Server bugs at Apple: Big Sur recovery fails, App Store in Mojave broken

Users of macOS 11 alias Big Sur once again report problems restoring their computer. Were there with macOS 11. 0 recovery difficulties over a longer period of time on M1 Macs, for which Apple provided a whole list of workarounds, This time, Intel machines are specifically affected. A recovery can be useful if you have problems with your macOS installation.

This time it’s Intel Macs Like the blog Mr. Macintosh was the first to report, the so-called Internet Recovery is now on strike with Intel Macs. The latest version of macOS can be obtained via the network and installed immediately, as long as the machine can establish an Internet connection from recovery mode – via WLAN or Ethernet.

Instead of offering the latest operating system version macOS 10. 1 alias Big Sur for download, only macOS has been released for a few days 10. 15 aka Catalina if you look at the internet – Want to initiate recovery on Intel Macs. Why this is happening is not yet clear – Mr. Macintosh speculates that this is a server-side problem. According to information in the MacAdmins forum, Apple has even unofficially communicated this to the outside world and announced that it is “working” on the problem. However, a deadline for a fix was not given. As mentioned, M1-Macs are not affected by the error because the recovery process takes place in a different way here.

App- Store error under Mojave Another server-side problem affects the Mac App Store. MacOS users 10. 14 aka Mojave can no longer use this permanently. When trying to update an application, the message appears – sometimes for weeks – that the system cannot “complete the purchase”. Below is a simple “canceled” (canceled). Developer Jeff Johnson was able to prove that the server “osxapps.itunes.apple.com”, which is necessary for the updates, simply disconnects – why is unclear.

Johnson speculates that Apple is definitely on the error his side and no – unlikely – update for Mojave is necessary. Especially annoying for developers: customers who cannot update their apps due to the bug contact the developer – and not Apple, although the Concentrate is responsible for the current problem.

Zyxel programmed back doors into firewalls

If you have a Zyxel device from the USG, ATP, VPN, ZyWALL or USG FLEX series, you should check the firmware version as soon as possible. Zyxel has in ZLD V4. 40 an access account with a fixed user name zwyfp and a fixed password that can be used to change the software of the devices. To make matters worse, these access data were even visible in plain text in a binary file.

The account cannot be seen in the account management, the password cannot be changed. The credentials allow access both via SSH and the web interface. This was discovered as CVE – 2020 – 29583 registered open barn door by Niels Teusink from the Dutch IT security company EYE at the end of November 2020. Zyxel Networks claims to have created the security gap for automatic firmware updates via FTP. Devices of the VPN series running under SD-OS are not affected.

AP controller NXC also affected – patch only in April Because permanently programmed access data is a really bad idea, Zyxel has the firmware version ZLD V4. 60 withdrawn and replaced by ZLD V4. 60 Patch 1. However, firmware version V6 is also affected. 10 of the WLAN access point controller NXC 2500 and NXC 5500. Because Zyxel doesn’t want to provide a patch until April, good advice is expensive. The patches should now appear on January 8th.

A random sample from EYEs showed that around ten percent of the Zyxel USG / ATP / VPN with Dutch IP addresses use the wounded firmware. Projected worldwide could be more than 10. 000 devices will be affected – found food for botnet operators and other culprits.

[UPDATE 04.01.2021 09:40]

Zyxel will point this out in an updated security warning that the security updates for the affected NXC series should now appear earlier (January 8th).

Does it matter which operating system the new Smart TV has? TechStage presents the most important OS for TVs in the guide and explains where they score.

Modern smart TVs no longer only differ in terms of appearance, equipment, and picture and sound quality. An essential feature is the operating system, which is largely responsible for ease of use. While the smartphone market is dominated by Android and iOS, several operating systems are competing for flat screen televisions. We will introduce you to all the important ones and address the respective strengths and weaknesses.

The article appears in our UHD TV theme world. There were other articles published there, for example our guide for really big TVs, tips for buying a next-gen TV or our constantly updated list of the cheapest TVs from all categories (e.g. OLED, HDMI 2.1 or just huge).

Android TV Not only on smartphones, but also on smartphones TVs are very popular with Android. In addition to Sony and Philips, TCL and Metz Blue rely on Android TV from Google. Corresponding televisions can not only be set up using the remote control supplied, but optionally using an Android smartphone.

Tile-like structure, clear structure and a lot of apps: that’s Android TV. #The start page has a uniform design on almost all Android TVs: Here you can find a list of the most important apps, streaming services and TV channels. All applications are arranged in tiles on the user interface; additional applications can be added in next to no time. While Android was still a bit sluggish and unstable to use in previous versions, these teething troubles have been resolved with Android 9.0 (Pie).

The gear wheel at the top right takes you to the most important system settings, the Google Assistant is lurking at the top left, for example to browse streaming services by voice or to call up current weather information or traffic reports.

The selection of apps under Android TV is generally huge and one of the best on the market. Thanks to the Google Play Store, you will find a varied portfolio in the areas of video, music, games and news. The integrated Google Chromecast ensures flexible compatibility with smartphones. While the standard interface is identical on all Android televisions, the individual manufacturers adapt their menus for picture and sound settings individually.

Overall, Android TV scores with a clear design, high operating speed and an extensive selection of apps. Smaller weak points in terms of performance can only be found on very inexpensive or older flat-screen TVs with an Android system. It is therefore important to check every now and then whether there is an update for your own TV.

Tizen OS With Tizen, Samsung uses its own operating system; the sheer number of Samsung TVs alone makes it a major competitor to Android TV. With Tizen OS, all functions are packed into a horizontal menu bar. You can store the most important apps here, preview streaming content, switch sources, open TV recordings from USB sticks and jump to the picture and sound settings.

Tizen OS from Samsung offers a lot of information at a glance and likes it colorful. All of this succeeds quickly even if the selected Samsung television does not have the fastest processor. In contrast to its competitors Philips and Panasonic, Samsung has integrated a powerful media player into Tizen OS, which can play photos and videos as 360 Degree view. In addition, there is a function in “Ambient Mode” to display paintings, photos or infographics with news or weather data on the screen when not in use. Alternatively, this takes on the look of the wallpaper behind the flat screen TV.

Relatively new is the intelligent program guide, which combines content from television and streaming services. In terms of apps, Samsung is one of the leading manufacturers on the market. In addition to HD +, you can also find Disney +, Apple TV, DAZN, Sky Ticket, Netflix, Tidal, Amazon Music, Spotify and Deezer. Tizen OS supports Apple AirPlay 2 to stream photos, music and videos from iPhone or iPad wirelessly to the hip flask, as well as Google Chromecast and Bluetooth.

If you like control by voice, you will also get your money’s worth with Tizen OS. A recent software update makes Google Assistant available on Samsung smart TVs in addition to Bixby and Amazon Alexa. Together with WebOS from LG Tizen OS is one of the most user-friendly and versatile operating systems on the market.

Web OS LG uses the WebOS operating system in its OLED and LCD televisions, which is visually reminiscent of the keyboard of a piano. The latest version, WebOS 5.0, is extremely fast and clearly structured. The high level of operating comfort is also due to the fact that you can control a mouse pointer on the TV with the LG remote control. So you can move the so-called Magic Remote freely in the air and navigate to the desired window like with a laser pointer. This is surprisingly precise and you get used to it quickly.

LG’s WebOS provides apps and functions like on a keyboard. The individual tiles give access to the TV program, the most important apps (these are freely configurable), the home dashboard – an overview of all connected and networked devices – as well as the art gallery, the sports alarm and the fast media player for 360 – degree representations. The art gallery contains paintings, photos and drawings that transform the LG TV, including a wooden or metal frame, into a deceptively real work of art. The sports alarm provides timely information about when your favorite team is playing again, for example in football or basketball, and provides constantly updated results.

With AirPlay 2 and the support of Chromecast and Miracast, WebOS 5.0 is very communicative. The range of videos and games in the app area is plentiful, including Apple TV, Disney +, DAZN, Sky Ticket, Google Play Films, Netflix and Zattoo. However, music and news apps still have room for improvement. The already installed application “Reelgood”, a streaming guide that bundles content from Netflix, Disney +, Amazon Prime Video and Maxdome, is very useful.

LG has thought of the Amazon Alexa and Google Assistant for voice control. In terms of handling and clarity, WebOS 5.0 is currently ahead, closely followed by Samsung Tizen OS, Panasonics My Home Screen and Android TV.

My Home Screen Panasonic equips its current flat screen TVs with the My Home Screen 5.0 operating system. This is clearly laid out, almost spartan, and requires little space on a flat screen. In the horizontal bar you can find the app icons from Netflix, YouTube and the “HD +” platform as well as access to the complete range of apps and an overview of all connected devices.

My Home Screen from Panasonic is limited to the essentials and is therefore intuitive to use. The sorting of the symbols is flexible, other applications can be added. You can also assign a button on the remote control to start your favorite app with just one press of a button.

New in My Home Screen Version 5.0 is the preview of thumbnails with various cinematic content as soon as you navigate to the streaming apps from Netflix and YouTube. The Panasonic software works quickly and smoothly with barely noticeable waiting times when changing menus. In addition to a DLNA server, My Home Screen also has the TV> IP function. This allows the TV signal to be transported over the network to a television set in another room in which no programs are traditionally accessible via cable, satellite or DVB-T2.

At Panasonic, the app offer is still expandable. With Disney + and Apple TV, two industry giants are missing here. Even those who like to stream music are currently losing out with the Japanese. When it comes to voice control, Panasonic is also not up to date: Amazon Alexa and Google Assistant can only be used in conjunction with separate speakers.

Loewe OS The traditional Loewe brand, which after the takeover by the Skytech Group was able to avert its final end at the very last second, is building its high-priced television with the Loewe OS6.3 operating system. In contrast to earlier Loewe TVs, the current models are easy to operate thanks to their attractive user interface with rectangular symbols and a simple menu structure. However, you have to get used to some little things first, such as the fact that a longer press on the “Home” button leads to the picture and sound settings.

The Loewe OS is clear, but important streaming apps such as Netflix are missing. The start page gives you access to the TV recordings that land on the internal hard drive. With the apps, however, you have to do without industry giants such as Netflix. These are only accessible via a Fire TV Stick from Amazon, which Loewe makes available to its customers free of charge after registering online. All applications on the streaming stick can be accessed via the heavy Loewe remote control.

In the spring 2021 Loewe wants to significantly expand the range of apps with a new platform. Loewe OS6.3 works quickly overall, but like Panasonic only enables voice control via Amazon Alexa via separate speakers such as the Echo Dot. Multimedia files can be accessed from a smartphone or a Fritzbox, for example. Loewe OS 6.3 has caught up with the market leaders from LG, Samsung, Panasonic and the like, but cannot quite keep up in terms of appearance and comfort.

Metz While the cheaper smart TVs of the Metz Blue series are delivered with Android, some Metz televisions come with a Linux Operating system used. This offers a special feature: The user can decide for himself how complex the user interface should appear. In addition, the number of functions can be gradually adapted to your own needs (“Simple”, “Comfort”, “Expert”). The start page and the submenus are kept very factual with clear labeling, but dispense with colored frills. But you know immediately which function is where.

The Metz user interface is based on a Linux system and attaches great importance to sober objectivity. The Linux system promptly implements control commands via the remote control and works at a good speed. The heavy metal signaling device with a well-structured key arrangement has reserved three keys so that preferred functions can be freely assigned to them.

If apps are important to you, you should think twice about buying a Metz TV. Because Netflix, Disney +, Apple TV, YouTube, Rakuten TV or Amazon Prime Video are just some of the relevant applications that are not available here. You have to buy a Fire TV stick separately.

Instructions are stored in the operating system so that you can look up almost any important topic quickly if you have any questions. Bluetooth and Chromecast are supported for streaming. Overall, the Linux operating system is very tidy and quickly transparent, without setting optical highlights.

VIDAA U3. 0 At the steadily growing TV manufacturer Hisense, the operating system listens to the bulky and somewhat getting used to name VIDAA U3.0. Here memories of Android TV are immediately awakened. This is ensured by the large tiles on the user interface, which not only include apps, but also the entrances and the media player.

Reminiscent of Android, but is named VIDAA U3.0: the operating system from Hisense . The operating concept is well thought out, Hisense dispenses with a nested menu structure and also makes life easy for new customers who previously trusted a different TV brand. There is also an aluminum remote control, which is also clearly designed and has four direct selection buttons for the streaming portals Netflix, YouTube, Rakuten TV and Amazon Prime Video.

Hisense cannot keep up with the range of apps from Sony, Philips, Samsung or LG, but the most important streaming platforms are on board. Via the home network, VIDAA U3.0 allows access to multimedia files that are slumbering on a PC hard drive or a media server in the network. The media player is, however, quite simple and neither does 360 – Degree representations still zoom in on photos. Amazon Alexa can be used for voice commands via voice.

Overall, VIDAA U3.0 makes a very smooth impression, but you have to be patient when switching and starting recordings on USB Bring your hard drive. Because the remote control does not have its own record button. Rather, you first have to navigate to the TimeShift menu and from here to the record button. Top dogs like LG, Samsung and Panasonic are still ahead in the area of ​​ease of use.

Conclusion The operating system of a TV may not seem essential at first glance. But it depends a lot on how you want to use the television in the future. Anyone who mainly watches traditional television or plays via a Blu-Ray player (guide) does not have to attach excessive weight to the TV OS. But if you use apps and streaming services, or stream video games from the cloud via a cloud service such as Shadow or Geforce Now, you should take a close look at what you are buying. Android TV is one step ahead here, and hardly any other manufacturer has app support.

The good news is that these functions can be upgraded if necessary. There are enough cheap streaming sticks, as our guide to streaming boxes shows in comparison. If you need a little more power, you should take a look at the Nvidia Shield TV (guide).

Robotics for the young: mTiny from makeblock

The Pragmatic Architect 02. 01. 2021 11: 08 Clock Michael Stal – 12 Comments

In a modern world it is important to introduce children to robotics and embedded systems. But what can you do without overwhelming the little ones? mTiny from makeblock provides a possible approach.

After a long period of health and work-related abstinence, I would like to continue my blog regularly. I start with light fare. This special is about mTiny from the Chinese company makeblock, which specializes in construction kits. In contrast to the company’s other products, mTiny is aimed at children aged four and over. It consists of a small robot vehicle, a controller, various programming cards and playing fields on which children from the age of four can solve various tasks.

The mTiny-Kit offers a wide range of accessories Programming The input of the programs consists of laying different programming cards one after the other including one each for the initial and final state. The junior programmer then runs the controller over the cards in the program. It always begins with the card for the beginning of the program. With a vibration, the budding developer learns: in that the controller has successfully read the respective card. At the very end she reads in the card for the final state, whereupon mTiny immediately starts executing the program.

Programs are strung together with cards which can then be read in by the controller. In addition to the card for the Beginning of programming (input card) and the card for starting execution (GO! Card), the package offers the following categories of instructions:

Action card : is used to move mTiny or to turn to the right or left. Facial expression card : with this it is possible to induce mTiny to make different eye gestures. Repeat cards : ensure that mTiny executes the preceding command two, three -, four or five times. Loop parantheses : are used to group several commands with an opening and a closing bracket. If this is followed by a Repeat card , mTiny executes the commands in brackets accordingly often. Loop cards: allow all commands to be repeated one to five times. With the start button of the controller a program can be started again, with its stop Key to stop the program execution.

Learning through practice In a small manual, the manufacturer describes various tasks with increasing levels of difficulty that children should solve. The basis for this are game worlds laid out with large cards.

Children can develop programs to cope with tasks in a play world. Unfortunately, this manual is currently out held in English, so requires the presence of an adult, which is necessary anyway, at least initially, in order to be helpful to children.

By the way, mTiny can also be operated using the joystick button remote control of the controller. According to the manufacturer, the connection works with a range of up to ten meters without any obstacles in between. In this respect, mTiny can also be used as a normal toy without programming.

Commissioning In order to put mTiny and the controller into operation, both must first be paired via Bluetooth. The user should then calibrate the controller’s joystick button with mTiny. To carry out this initialization, it is recommended that both devices have a charge level of at least 50 percent.

Important recommendation: In the test, the coupling only worked when both devices were positioned outside the 2.4 GHz WLAN at home. After the coupling was successfully established once, there were no more connection problems.

The remote controlled vehicle and the controller after bluetooth pairing. The charging of both mTiny as well as its controller is carried out simultaneously via a micro USB Y cable. When connected to a PC via USB, the computer recognizes mTiny as a USB drive. The provision of new firmware is done via the mTiny service page. To update, users copy the extracted zip file to the main directory of mTiny. After switching off and on again, the update of the mTiny and controller takes place automatically in a few minutes.

A question of price The official list price of mTiny is 159 Euro, whereby the street price is only 98, 80 Euro – at least, reichelt.de offered mTiny at this price during the period of article creation. A price comparison is worthwhile.

Conclusion mTiny is well suited to introduce children from the age of four to robotics and programming in a playful way. The concept seems well thought out and expandable. Overall, the product is recommended.

There are minor blemishes:

Makeblock should also deliver all manuals in German. The reading also works the program card with the controller was notchy at first. Only after a familiarization phase do the users get the hang of it. For a street price around 100 to 130 Euro the overall result is a good price-performance ratio.

My thanks go to the company solectric, who lent me mTiny for this item.

Fitness trackers are available in various price categories and with a different range of functions. TechStage shows in a comparison test which device is suitable for which requirements.

If you want to buy a fitness tracker, you will find a large number of potential devices on the market that want to lure users with various features and often with low prices. We have tested numerous products in our fitness tracker theme world, all of which have an integrated pulse measurement and sleep analysis:

Fitbit Inspire 2 (test report) Fitbit Sense (test report) Amazfit Volume 5 (test report)

Xiaomi Mi Band 5 (test report) Beurer AS 99 (Review) Realme Band (test report) Fitbit Charge 4 (test report) Honor Band 5 (test report) All devices have strengths and weaknesses that we have in this comparison test weigh against each other to clarify which tracker is for which need and what customers should pay attention to when purchasing.

Fitness and pulse measurement What all trackers in our comparison test have in common are pulse measurement and step counter: The devices all measure the pulse via an optical sensor and record steps taken. The Fitbit Sense also counts the floors you climb every day. All trackers worked without any problems in the step counter test and reliably recorded the steps taken. They also all allow you to set individual daily goals using the app provided. If we have reached the daily goal, the trackers inform us about it.

The permanent pulse measurement also works reliably with all trackers: The deviations from measurements with the pulse belt were in the low single digits in any case Percentage range, whereby all trackers allow a useful long-term analysis of the heart rate. The Amazfit Band 5 and the Xiaomi Mi Band 5 also classify our pulse into different categories and indicate how much time we spent in a relaxed state, with light exertion and intense activity.

In addition to steps and pulse, all trackers also measure the calories burned during the day, but evaluate them relatively conservatively. In addition, some trackers offer an activity index that users can use to set specific goals for active minutes per day. The Amazfit Band 5 has the Personal Activity Index (PAI) for this, the Fitbit Inspire 2, the Fitbit Charge 4 and the Fitbit Sense offer a comparable function.

Training The trackers differ less in terms of training functions than in our previous comparison test. Almost all trackers have a sometimes very extensive portfolio of different sports that can be recorded with the device. Classics such as running, cycling and swimming are included here, as are yoga, cardio, weight training and sometimes more exotic candidates such as rowing on the machine or jumping rope (Amazfit Volume 5). The largest selection is offered by the Amazfit Band 5 and Xiaomi Mi Band trackers, the last one being the Fitbit Inspire 2, which only offers profiles for running, cycling, swimming, treadmill, weight lifting and interval training. The Beurer AS 90, on the other hand, falls again significantly because it is only Records sports in which steps taken can be measured. Overall, however, all other trackers cover a sufficient amount of sports so that amateur athletes should be satisfied with each of these devices.

All trackers are also waterproof and survive a trip to the swimming pool or under the shower. Some devices can also record running and cycling routes with an integrated GPS (including the Fitbit Sense and the Fitbit Charge 4). The other trackers use the GPS of the connected smartphone or measure the stride length. Even without GPS, the detection of the route length worked comparatively well with all devices – so you can also use a device without GPS if you don’t always want to take your smartphone with you. The Fitbit Sense even allows us to set the length of the lap while swimming and then counts the lanes swam. Most trackers also have training profiles for strength training, but none of them were really convincing in our test – the measurements of the individual repetitions were too imprecise.

Displays and controls Even if some manufacturers have improved the screens compared to previous models, some trackers fall significantly compared to their competition from. The devices all have a color screen, most of them with an OLED or AMOLED display, and can be operated using touch controls. This works everywhere without any problems, but the readability of the display on the Amazfit Band 5, the Fitbit Charge 4 and the Fitbit Inspire 2 leaves a lot to be desired – the screen is too dark in both cases in direct sunlight.

The Fitbit Inspire 2 also suffers from the fact that the display does not activate automatically when you touch it and we first have to press a side button before the screen appears. The Fitbit Charge 4 had a negative impact in the test when it came to touch operation because the tracker did not correctly recognize individual swipe gestures and the menus jerked.

The Fitbit Sense, Xiaomi Mi Band 5 and Honor Band 5 offer the best display, all of which convince with a sharp display and excellent brightness.

Apps Anyone of us If you want to use a tested fitness tracker, you must install an associated app on your own smartphone and create a user account. This works in all cases without any problems, but before we can use the individual devices to their full extent, we first have to click through various data protection declarations and consent menus.

If you can live with it, you will get good and clear apps for controlling the trackers across the board. All services provide intuitively operable statistics and menus with various information on collected data. The Zepp app of the Amazfit Volume 5 also has its own AI algorithm that analyzes the data and prepares its own recommendations. The Fitbit app focuses on maximum clarity and presents data from several days directly below one another, which actually promotes an overview. Beurer is apparently primarily aimed at an older target group and has therefore designed its own app to be rather simple and a bit conservative, almost old-fashioned. This also affects the overview and the rather cumbersome operation.

All trackers also allow notifications to be shown on the display. Users can set separately which apps are allowed to send such notifications in the respective smartphone app of the tracker.

Fitness tracker in comparison (2020) (9 pictures) Visually, there is little variety in the cheap fitness trackers, but inside they differ significantly.

To the fitness tracker theme world

Sleep Even if the meaningfulness of the sleep analysis of fitness trackers is still limited, show the devices we tested show long-term trends. The devices measure our pulse and, in most cases, automatically notice when we fall asleep and wake up. The respective apps show how much time we spent in which sleep phase. Fitbit trackers evaluate our sleep with a special sleep index that includes all measured sleep data and enables our sleep quality to be compared over a longer period of time.

The Xiaomi Mi Band 5 analyzes our sleep and then makes additional recommendations on how we can improve our sleep quality. Apart from the Beurer AS 90 we felt the measured data on all devices at least subjectively as credible and reliable. The Beurer AS 99 had problems with the sleep analysis: It was inaccurate Measurements of the waking phases and once the sleep tracking stopped in the middle of the night for no apparent reason. We have to work with Beurer AS 99 also activate the tracking separately before sleeping. The Beurer app then does not provide any information on the heart rate during sleep – a no-go in our opinion.

Finally, all trackers have an integrated vibration alarm clock, which always worked reliably. The Huawei Band 4 and Fitbit Inspire 2 also have a special do not disturb mode that we can activate in the tracker’s menu as required. The devices also lay comfortably on the wrist while sleeping, there were no unpleasant pressure points.

Battery life Depending on which functions we activate on the trackers and how intensively we use the individual tracking features, the battery life varies. Almost all devices in our comparison test lasted at least a week with activated notifications and regular use including training functions.

The Fitbit Sense had to lose some battery life when the GPS function was activated and it brought it with a training session including GPS per day for five days. At the bottom of the list is the Beurer AS 90 with only four days, while the front runner Amazfit Band 5 and the Xiaomi Mi Band 5 easily hold out two weeks.

The advantage of all trackers: The battery can be charged very quickly and takes a maximum of one hour. Corresponding charging cables are included with all trackers, but these differ depending on the model and rely on different connections. We didn’t notice the latter negatively in the test and we found them to be user-friendly throughout.

Particularities The individual trackers from our comparison test mostly rely on a similar look and comparable features, but most of them have Devices have a few more unique features. The Amazfit Band 5, for example, supports voice control using Amazon’s Alexa – a feature that no other tracker can offer.

The three Fitbit devices include a free year of Fitbit Premium when purchased. The service offers, among other things, training programs lasting several weeks with instruction videos, virtual competitions with other Fitbit users, mindfulness and meditation exercises, and detailed health reports. The Fitbit Sense also allows you to answer and make phone calls and can be controlled by voice.

The Mi Band 5 from Xiaomi compares our sleep data with that of other users and gives us based on it individual recommendations for our sleep hygiene, while the Honor Band 5 also measures the oxygen saturation of the user in the blood. The Beurer AS 99 and the Realme tape do not have any additional features worth mentioning.

Conclusion Although all of the fitness trackers we tested have individual strengths and weaknesses, a few clear winners and one clear loser emerge in comparison. Our overall winner is the Fitbit Sense, which with just under 122 Euro costs by far the most, but it delivers the best overall performance and provides users with an all-round carefree package. This is not only due to the excellent display, but also to the wide range of different tracking functions as well as the integrated voice and telephone control.

As the price-performance winner, the Xiaomi Mi Band 5 comes off with us, which scores with an excellent display, a very long battery life and extensive training functions. The cheap price of just under 30 Euro makes this tracker a real bargain. Almost equivalent alternatives are the Honor Band 5 and the Huawei Band 4, closely followed by the Amazfit Band 5, whose screen, however, cannot keep up with that of the competition.

We liked the Fitbit Inspire 2 less, the Compared to the Chinese competition, it offers too few features for three times the price, and the Fitbit Charge 4, whose display leaves a lot to be desired in terms of brightness and control.

The two taillights, which we currently advise against buying, are in our comparison test of the Beurer AS 99 and the Realme Band. The Beurer AS 99 suffers from an old-fashioned presentation and awkward operation – both exist it is better and cheaper with the competition. In addition, the Beurer AS does not have 99 sufficient tracking functions for athletic training. In the test, the Realme Band showed clear problems with heart rate measurement and sleep tracking, which is why we cannot make a recommendation here either.

Amazfit Fitbit Fitness tracker Realme Xiaomi Huawei Y5 (2017) : new entry-level mobile phone being tested Devolo dLAN 1200 + WiFi ac: Powerline Starter Kit in the test

the-wide-range-of-the-range-(ii.):-helmut-on-the-cooling-mat

The wide range of the range (II.): Helmut on the cooling mat

Since my train was stranded and the iPhone had nothing more to say, I listened to Helmut the bus driver. The air conditioning is currently insufficient, he said, so he got a coolkeeper, a special seat mat so that he doesn’t have to stew in his own juice the whole shift. Fortunately, he drives a diesel-powered bus and not an electric one, so you have to be careful with the energy and you can’t just turn up the air conditioning, even in the heat like it is now. Then it could happen that the bus simply stops on the route. “I don’t have a spare canister then,” he insisted.

While I was paddling through potatoes, I could as a native city dweller, don’t imagine living there; as always when I drove across the country, even as a child, when I visited relatives with my parents, just under an hour’s drive northwest of Nienburg. At least for some errands I would have to rely on the car, I probably couldn’t just take public transport to work or even cycle. That for me as a passionate pedestrian who can switch to a bike or tram in the city for a quick trip and handle larger transports with the sharing car or that of a friend. The foot pressure would probably be even stronger if I lived in Schwabing, where, according to a BMW study by 1997 all motorists combined Every day 80.00 should have spent 0 kilometers searching for a parking space.

Reserve canister Normally at the end of the day I can’t remember which topics I worked on during the working day. They can then no longer be queried directly, they seem to be shifted into a kind of foreshadowing memory. When I come across a topic, I suspect that I had it on the table not long or a long time ago, and I can narrow down the archive search accordingly. On this Tuesday, however, I had another dpa message in mind: “Car traffic causes follow-up costs of 141 Billion euro”. In the year 2017, the alliance had calculated per rail. The costs would not be borne by the polluters alone, but by the general public. Criticism came from the FDP that it was tendentious to argue only with the follow-up costs and to ignore the benefits of mobility. As liberals, in the tradition of Adam Smith, you mean, of course, the economic benefits for the benefit of all.

Mobility includes immobility, cars stand around most of the time . In the country there are endless parking spaces for this, where the prerequisites would be more likely to charge the electric car in front of one’s own front door, as most owners of such cars are currently doing in view of the thin infrastructure and long charging times. In the city, on the other hand, the proportion of rental accommodation is high, there are quite a few multi-party houses, like the one in which I live, and correspondingly little parking space. Many apartment buildings have no parking spaces that are suitable as charging stations. After all, the legislators want to promote the private installation of charging stations by strengthening the rights of tenants.

“Reserve canister” was my catchphrase, thinking about the now empty power bank, about the system, even paradigm shift that came with the switch from Xenium to iPhone. Always keep an eye on the charge level and thus the option benefits, and if it fell below a certain threshold, keep your eyes wandering to the nearest socket. If someone seemed to be reachable, “may I” ask and mark the area with a plug. Middle of 00 he years, when people with touchscreens increased in the trains and subways I used, it became common in some pubs – at least in Stuttgart I had seen this more often, less in Bremen – for people to have their smartphones in front of them laid the table. In a cozy atmosphere it became tight between the beer and wine glasses in a high-tech, status symbolic way.

Trimmed expectation On this last Tuesday in August 2019 it was just a week ago that Chancellor Angela Merkel expressed her expectation to like one on Germany’s streets Drive a million electric cars, from 2020 to 2022 had moved. Germany was still many thousands of electric vehicles away from the destination. An electric car is possibly a status symbol, but one that cannot be plugged in or put on the table.

The German fear of electromobility seems to be giving way, well encouraged by the Purchase premium offered by the state and manufacturers. From January to October 2020 were 121. 500 purely battery-electric powered cars newly registered, 130 percent more than last year. The federal government’s electromobility funding program has existed since July 2016 and was initially adopted very hesitantly. Four years later it is on many lips and often a quiet car sneaks past my living room window. The call of money is weighted on the scales against the fear of range, this special form of German fear.

“That’s why I wouldn’t buy an electric car privately. How should I go on vacation with it? “, the bus driver interrupted my thoughts from the future. “Please?” I winced. “I go to Spain with my wife every year,” said Helmut, “on the way I find petrol stations everywhere. But what about charging stations? Besides, after ten minutes I’m through with refueling. Do you know how long it takes to get one Fully charge your electric car? ” I thought of a message that I had written two years earlier: Three men had driven their Tesla from the North Cape to Tarifa and had 86 hours needed. Only for the loading went there 10 hours on it. In normal reality 70 percent of drivers in Germany daily maximum 50 kilometers, 17 percent between 50 and 100 km, Eon had found out through a survey. At the same time 20 percent expected from one E-car with a full charge between 141 and 500 km range, 21 Percent more than 500 km.

isochrones – Card by Francis Galton.

The British naturalist Francis Galton had 1881 produced an isochronous map. He colored areas on a world map that could be reached from a certain point – namely London – within a certain period of time. Within ten days to the Urals, 40 Days to Australia or central South America; Assuming the most favorable travel conditions and costs. The first electric cars were already around at that time, but I don’t know whether Galton included them in his considerations. Probably not, because at that time steam-powered vehicles such as ships and trains were more suitable for the range.

Delirium furiosum First train passenger 40 Years before Galton’s first isochronous map, it is said to be traveling with 30 km / h have become bad, medical councils are even said to have warned against a delirium furiosum. At the latest since Chuck’s Yeager’s flight 1881 with a Bell X-1 through the sound barrier, we can know that too higher speeds can be survived; Yeager only died 73 years after his pioneering act. The force that an electric car pushes the occupants into their seats when starting off in a sporty way has not harmed people either. What could the astronauts who were shot into space by the Saturn V say?

Today, since most of the world’s points can be reached within a few hours to days, isochronons have maps for normal people not as important as, for example, the broadband or mobile communications atlas. The one for Lower Saxony nowadays has hardly any dead spots. That was before 13 Years different when I started commuting from Bremen to Hanover by train. In order not to let the travel time pass unused, I went online with a UMTS stick on my laptop early in the morning in Bremen’s main train station, looked for topics for reports, researched and drove into a dead zone where I could write the report. If I was finished with the report, I could put it in the editorial system shortly before Verden or not, if research was still required. Then I used the reception until shortly after Verden, drove into the next radio hole and then had Internet again in the area around Nienburg. The third dead zone followed between Nienburg and Hanover.

Over the years I had become so used to the rhythm that I kept it when the ICE finally offered a continuous connection via WLAN. WLAN was already available in the ICE, but just like my UMTS stick it understood every radio gap. It only offered the opportunity to conserve my data volume if it worked. Sometimes the WiFi worked, but the router behind it wasn’t connected to the internet. When I pointed this out to the train drivers, they either asked me what I wanted, the WLAN was switched on, or they said the router had to be restarted, that would only be possible in Hanover, the destination of my morning journey.

No, reservations are no longer transferred to the displays on the seats via diskette, that has not happened for a long time, assures Deutsche Bahn. The reservation data would be on a DB server and would be received on the train via a modem or mobile phone via cellular network and then shown on the displays. But here, too, there are of course pitfalls, because it could well happen that the connection to the server can only be established after the journey has started, or not at all. Malfunctions on servers or cell phone providers could also prevent data transmission. The result: “Release if necessary.”

A jolt brought me out of my thoughts about yesterday, today and tomorrow, the bus reached Hoya and crossed the Weser. Here I had to change trains and, contrary to the written prohibition, spoke to the driver where I had to get off to get to Hassel, especially since the area had quickly become more rural again. “Oh, we’ve already passed the train station. But I’ll turn around for you and drop you off there.” He said, turned around and dropped me off a kilometer later.

City-ATM: Researchers test traffic systems for unmanned flying objects

Scientists are working in the City-ATM project on counterparts to traffic lights, priority and stop signs in urban, largely uncontrolled airspace up to 760 meters above ground. The integration of unmanned aircraft into traffic with larger aircraft has long been considered a challenge. Observers expect that the use of quadrocopters, unmanned helicopters and larger fixed-wing aircraft will increase significantly in the next few years, especially over larger cities.

Yes Now it is no longer a pure science fiction scenario, which Dagi Geister from the Institute for Flight Guidance at the German Aerospace Center (DLR) describes: “A parcel drone delivers a consignment of goods in the front yard of a single-family house. Upstairs, autonomous air taxis bring commuters to their workplaces in the city. Small unmanned aerial vehicles hover over the intersections of the city center. ” In order to ensure safe and efficient operation between old and new road users in the divided urban sky, many boundary conditions would have to be observed and clarified.

With the City- ATM, the institutions and companies involved want to develop a concept for future air traffic management (ATM). In the project, which has been running since 2018, several DLR institutes are working with partners such as NXP, FlyNex, Deutsche Flugsicherung (DFS), Kopterkraft, Auterion, the Center for Applied Aviation Research and the Society for Aviation Informatics together.

Drone detects fire Tested in autumn the participants at the National Test Center for Unmanned Aviation Systems in Cochstedt, for the first time, whether and how several drones can be safely handled in sudden dangers. The researchers simulated a fire with smoke bombs. The swath was discovered by a special drone for authorities and organizations with security tasks (BoS), which is operated by the DLR Institute for Optical Sensor Systems.

After the source of danger was identified, the operator of the BoS drone created a no-fly zone around the “fire” and uploaded this information to a central FlyNex server to which the ground station was also connected. The employees there have entered the red zone in the internal database, in which the local air traffic from DFS has already been entered. Alexander Kuenz from the DLR Institute of Flight Guidance explains: “Among other things, this enabled conflict detection and avoidance with the controlled drones.”

The ground station meanwhile shared the coordinates of the danger zone with the three quadrocopters in the air With. According to Kuenz, they independently recognized whether they were near the danger zone. If so, they immediately held their positions and waited for new instructions from the control center. The scientists were then able to guide the drones around the prohibited zone.

Drones in a complex environment The flight systems communicated via D2X -Funk (Drone2X) based on the standard 760. 11 p with the ground station. D2X is based on the WLAN specification for “Car to Car Communication” (C2X). Kuenz rates the trials overall as “successful and very promising”.

The airspace of the future is being explored (8 images) Admission the smoke flare and geofence illustration. (Image: DLR) 2019 the researchers had undertaken another experiment at the Köhlbrand Bridge in Hamburg. They wanted to show how the cooperation and communication of drones in the complex environment of a busy urban artery already works over water, says Kuenz. It was also able to “successfully demonstrate the exemplary detection of fine cracks”. The ship and road traffic continued during this time.

City-ATM runs until the end 2021 . In the next larger action, some physical drones are to be used in a confusing, largely virtual traffic scenario with about 100 more unmanned flight systems are moved. They should be guided both from the ground and autonomously on board. Until then, the scientists want to equip the devices with further special technology to be on the safe side.

From just under 20 Euro it starts .

Sensible headphones belong for the most athletes basic equipment. Those who are not currently doing a team sport want to have some peace and quiet while training. It goes so far that you want to be isolated from the rest of the athletes in order to concentrate on your own routine. Good headphones are tools for bringing the music from the smartphone or another player to the ear reliably and in good quality. And they differ from “normal” headphones in terms of construction. The devices for athletes have to be stable in the ear, even with jerky movements. And they should be protected against sweat or splash water.

In recent years, we have tested numerous sports headphones in a wide variety of price ranges and designs in our sports headphones theme. This ranges from classic Bluetooth headphones such as the Soundbuds Flow from Anker (test report) to the Bose Frames Tempo (test report) to the JBL Reflect Flow (test report). In this comparison test, we show which functions good sports headphones have to fulfill and why the sound is good even with inexpensive devices. To do this, we choose our current test winners, show inexpensive alternatives and present alternative concepts.

Design type Sports headphones are now mostly available as in-ear devices. They sit directly in the ear, usually held in place by special silicone wings. Compared to other designs such as over-ear or on-ear, in-ears have the advantage that you don’t sweat under the headphones. However, there are many who find the plugs uncomfortable. One option is, for example, to hold devices such as Airpods on the ear with a special silicone clip. More about this in our guide The most important accessories for Apple Airpods.

In addition to the classic forms, there are always experiments. Aftershokz is known. The company uses vibrations to transmit the sound via the skull bone into the inner ear. This works well and leaves the ears free, but the sound quality suffers especially with podcasts or audio books, as we show in the test for the Aftershokz Trekz Air (test report). The frames series from Bose relies on sunglasses with speakers in the ear hooks. This works very well with the Bose Frames Tempo sports glasses (test report).

At the same time, the advantage and disadvantage of in-ear headphones is that they are sealed off from the outside world. The JBL Reflect Flow (test report) are a good example of this. They sit so tightly in your ear that it’s easy to forget the world around you. This is great when training in a safe environment, such as bouldering or jogging in a secluded area. However, it is a problem when you are out and about in traffic. If you cycle on or next to the road, you have to be aware of the traffic around you. Yes, you can activate an ambient mode in devices such as the Reflect Flow and other in-ears, then the noises are passed through from the outside. That sounds very artificial, however. Devices such as the Bose Sport Earbuds (test report) have a better balance, but do not seal off the user so blatantly during exercise.

Comparison test sports headphones (6 pictures) The Reflect Flow from JBL are our first test winners for everyone who completely from sports want to be isolated from the outside world.

For the single test

Protection against sweat and water All headphones for Athletes should be protected against water. It is less about swimming or diving with them. Rather, it is about protection against sweat and the possibility of briefly rinsing the equipment under running water.

The protection against water is easiest to read from the IP protection class. The rule of thumb is: the higher the IPXX number, the better the headphones are protected against water. The table shows what the individual numbers mean. Our tip is that the headphones should have at least IPX2.

IPXX protection classes 1st digit Protection against contact / foreign bodies 2nd digit Protection against water 0 unprotected 0 unprotected 1 Protection against foreign bodies> 50 mm / protection against contact with the back of the hand 1 Protection against Dripping water 2 Protection against foreign bodies> 12 mm / protection against contact with the finger 2 Protection against dripping water 2.5 mm / protection against contact with tools 3 Protection against spray water 4 Protection against foreign bodies> 1 mm / protection against contact with wire 4 Protection against splash water 5 Protection against dust / protection against Touches 5 Protection against en water jets 6 dust-proof, protection against contact 6 Protection against heavy water jets 7 Protection against temporary immersion 8th Protection against permanent immersion Source: Heise.de True Wireless or Electric wire? In the last version of our comparison of sports headphones in 2018 the classic Bluetooth headphones with cables between the speakers dominated. Since then, this design has had massive competition from the true wireless approach. The headphones no longer have cables, they connect to each other and to the playback device, such as a smartphone, via Bluetooth. This technology has developed massively in recent years. Where in the past there were sometimes large audio delays, for example in movies or games, the sound can now be heard without latency. The battery life has also improved enormously. The big advantage of the in-ears is their charging cradle. With classic Bluetooth headphones, it happens again and again that they are empty when you need them. True wireless devices, on the other hand, are usually in the charging cradle and thus always have enough charge to be used for a sports session.

Sound The good news: The sound of most sports headphones, including cheap devices such as the RF-BTK – 300 by Renkforce (test report) or the Anker Soundbuds Flow (test report) is now so good that it can be used for sports without any problems. In particular, the cheap devices tend to have a strong to excessive bass. The formula expensive = good sound has long ceased to apply.

With the classic audio brands you can tell that the nuances are sometimes better. In addition, Bose or Jabra, for example, often rely on AAC as an additional codec for the transmission of lossless content. This is often lacking in cheaper headphones. If you value such content in sports, you should adjust your selection accordingly. The inexpensive headphones are also good for streaming Spotify & Co or for podcasts. We write more about the sound of the respective headphones in the linked individual tests.

Test winner and recommendations Our test winners are the Bose Sport Earbuds (test report) and the JBL Reflect Flow (test report). Both sports headphones offer a well-balanced sound, sit firmly in the ear and have enough battery power to endure even longer sports sessions. They are also both comfortable to wear. We recommend the JBL Reflect Flow to everyone who wants to completely isolate themselves during sport. They are one of the few headphones that really deserve the title “Passive Noise Cancellation”. The Bose Sport Earbuds allow more surroundings to pass through without affecting the sound quality. A good third alternative are the Jabra Active 64 t (test report ). We liked the fact that they are easy to use, are well protected against water and sweat and offer great additional features. The price has now leveled off in reasonable regions.

Among the price-performance winners, we mainly see the cheap Anker Soundbuds Flow headphones (test report) and the Renkforce RF-BTK 300 (Review). Both are protected against water (IPX4 and IPX5), well made and magnetically adhere to each other. So you can click them together in front of your body when you don’t have them in your ears.

The special mention goes to the Bose Frames Tempo (review). As with the Aftershokz Trekz Air (test report), the ears remain completely free, so you can easily see the surroundings. But the sound of the Tempo frames is significantly better than that of the bone conduction headphones. Especially with speech, such as audio books, podcasts or audio announcements from the navigation system, you can hear the tempo better with the frames. The disadvantage of the Tempo frames, however, is that they cannot be used just like that. Despite good sound and low latency, you just look stupid when you stream Netflix with it.

Conclusion Anyone who has ever got stuck with the headphone cable while doing sports knows why you should only rely on Bluetooth headphones. The good news is that the cheap devices from Anker or Renkforce in particular also deliver decent sound. For scarce 20 Euro is already available good wireless headsets.

If you want to spend more, you should use a true wireless system. Not only does not a cable get tangled in the bag, thanks to the transport box with battery, the headphones are in most cases so charged that you have enough juice for exercise.

We show even more on the subject of headphones in our individual tests in the subject world of true wireless headphones. Here, too, you can clearly see how prices have been falling in recent years. A suitable guide to this is true wireless headphones under 90 Euro in the comparison test , the guide to true wireless noise-canceling headphones, or the article on the cheapest true wireless headphones.

If you want to track your training progress properly in addition to headphones, we recommend a look at our sports watch or our tested fitness tracker.

Security nightmare: Many networked doorbells let hackers into the house

The IT security of “intelligent” doorbells equipped with video cameras, which can be bought for comparatively little money on online marketplaces such as Amazon, eBay or Wish, is not well ordered. This was the result of a test by the IT security company NCC Group for the British online magazine “Which?” surrender. The identified weaknesses therefore range from logon information that is firmly encoded in the hardware, to authentication problems, to data transfer to China. In some cases, the devices are delivered without the latest security updates being installed and long-standing critical errors have been corrected The researchers should find out what smart bells are good for, which cost significantly less than the market leaders from Amazon Ring or Google Nest and mostly come from China. They examined models from Victure, Qihoo and Accfly as well as unbranded products with titles like “HD Wi-Fi Video Doorbell V5”, “Smart WiFi Doorbell (YinXn)” or “Smart Wifi Doorbell – XF-IP 007 H “.

Overall, the experts give the devices a bad rating, which is a” nightmare “in the area of the Internet of Things. The security problems beyond aggressive data collection are massive. In addition, some of the video bells turned out to be “clones” of the Victure model, which not only took over its flaws, but also made them worse. The original contained an undocumented HTTP service on port 80. This required login data which could easily be extracted by one of the “Copy Cats”. Unencrypted WLAN IDs and passwords were found in log files.

The smartphone apps for controlling the digital bells also rely on unencrypted communication, which makes life easy for hackers. “HTTPS was not enforced on a number of devices or did not even exist as a communication method for a number of mobile applications,” the analysis said. For example, the Victure mobile application requested a root certificate via an HTTP request. Sensitive information, user names and passwords could be recorded with simple test instruments.

So many attack possibilities We encountered the Qihoo device the auditors on an undocumented, fully functional DNS service. In principle, this could simply be misused as a channel for the spread of malware. Current indications of such an active “rabbit hole” were not detectable.

Another possible attack vector was the misuse of QR codes. According to the report, a hacker who has access to a user’s cloud-based camera backup could also get their hands on the device’s QR code. The attacker could decrypt it and read the WLAN data with a password.

According to the researchers, the bell hardware is often not securely attached. It was then easy to remove and manipulate. The devices would usually sit loosely in a screwed or glued-on bracket. They could be stolen within a few seconds. Only one of the camera systems had a pressure sensor, which triggered an alarm if tampered with. This can also be prevented by a 2.4 GHz jammer.

No good words Help me the hardware is an attacker in a position to access the videos recorded by the bell and stored on an SD card, the experts say. For example, he could research the typical behavior of residents. In addition, the firmware can be extracted in order to obtain the access data to a network again or to identify further weak points.

The researchers found that one of the devices was still used for “key reinstallation attacks” (Krack ) was prone. This WLAN gap should actually be sealed since 2019. It enables attackers to read encrypted data traffic in plain text, to steal information and – depending on the network configuration – to smuggle in malicious code. Accfly and Victure, the only ones to publish contact information, did not respond to inquiries from Which. US civil rights activists had previously criticized the fact that ring apps are also big data throws.

TechStage | Spotify Connect guide: networked speakers from 40 €

Start Spotify Connect Session Playback Conclusion Comments Spotify Connect lets music, audio books and podcasts run on networked speakers. We show how the technology works and which devices are compatible.

music streaming doesn’t always have to be on the phone. The output can be redirected to loudspeakers, TVs and other end devices via Spotify Connect. The function is an integral part of Spotify, all you need is an account and a compatible speaker in the same WLAN.

This is not only great for listening to music. Podcasts and radio plays in particular, for example for children in lockdown, can be easily redirected to proper speakers via the smartphone.

What is Spotify Connect? Put simply: Spotify Connect connects speakers and TVs with the streaming service so that music or podcasts can be played there directly. It is controlled via the app, the desktop software or the web player.

Spotify Connect has several advantages over playback via Bluetooth. The bit rate is up to 50 kbps, this corresponds to the quality setting “Very High” for premium users. The end devices connect directly to Spotify and pull the music directly from the web. In other words, there is no mobile phone in between that has to convert the songs and send them via Bluetooth. This also means less stress on the cell phone battery, the smartphone can still be used for phone calls and it does not have to be constantly within range of the loudspeaker. At the same time, every installed Spotify instance that is logged into the same account becomes a remote control. An example: If you listen to music on your laptop through headphones, you can control playback via the smartphone app or transfer the sound from the headphones seamlessly to other speakers. This even works with smart watches, such as the Fitbit Versa 2 (test report).

With Spotify Connect, a wide variety of end devices can be controlled from Spotify. Spotify Connect works similarly to Apple’s Airplay. The technology searches for all compatible end devices in the current WLAN network. Pairing is not necessary, all devices found in the same network can be used immediately for playback.

The control is simple: In the app, desktop program or the web player you click on the icon for “Connect to a device”. This shows a monitor behind an MP3 player; it is located in the lower right corner of the desktop and web app, between the playlist display and the volume control. For the smartphone app, it is at the bottom left, below the shuffle icon.

A click on it shows all speakers and other Spotify instances that are active in the same network or with which the user is currently logged in. Another click starts the connection with the device, shortly afterwards the playback switches over automatically. Spotify Connect can be activated during playback in the same way as before.

Spotify Connect (4 pictures) Spotify Connect transmits the audio output to other devices and speakers.

Spotify Connect is not a real multi-room solution. From Spotify you can output the content on one device, but not on multiple speakers in the selection. A real multiroom system is required here (adviser). Because Spotify can stream to speakers that are coupled to each other. So if you have several Sonos devices (theme world), for example, you can define them as a group in the Sonos app and then access them from Spotify.

On the other hand, Spotify Connect has an advantage over most multiroom systems: it can be used with the free one Account possible. However, the usual restrictions (bit rate, advertising) apply. However, there may be restrictions depending on the country and manufacturer.

Spotify Session: Together Listening to music A new premium feature from Spotify are the sessions. You can invite up to five people to listen to a playlist together afterwards. It doesn’t matter whether the people are in the same room or somewhere else on earth. That allows for a few cool scenarios, for example when you celebrate alone at the turn of the year but still listen to the same music together. The playback itself continues to run normally, that is, the songs can also be played back on a Spotify Connect-enabled device. You start a new session via the dialog in which you can also find the external playback devices.

End devices: speakers , TVs, systems, soundbars Spotify is now extremely widespread. Almost every multiroom system is compatible, plus Alexa devices and every end device with Google Cast or Chromecast. In other words, the user is spoiled for choice. It is important that the respective device has WiFi, this is the basic requirement for Spotify Connect. Then it is worth taking a look at the technical data. Wherever Spotify Connect or Chromecast is mentioned, you are on the safe side.

The cheapest entry is a simple networked loudspeaker, Medion and other manufacturers offer devices from just under 40 Euros. Sure, nobody expects a sound technical revelation, but as a device for the workshop or the kitchen it easily does. If you want to pick up more, you should consider a real multiroom loudspeaker right away. Sonos is still the top dog, but other manufacturers are also worth a look, as our guide Multiroom: Sound in every room shows.

Alternatively, there are compact systems that now also support streaming. Anyone who already has a “real” hi-fi system has several options. There are network streamers that can play music from the LAN and from Spotify and are integrated like normal audio components. Alternatively, the amplifier can be exchanged for a new variant that has integrated streaming.

If you are looking for a portable speaker that has streaming functions and a battery, you have something heavier. There are devices such as the Sonos Move (test report), the Bose Portable Home Speaker (test report) or speakers from Libratone. When it comes to televisions, you are largely limited to devices with Google Cast. They can safely handle Spotify Connect. In our opinion, it actually makes more sense to play the music on a loudspeaker or soundbar.

Conclusion If you buy a new loudspeaker or a compact system, you should at least roughly have the Spotify Connect function in mind. This applies twice to everyone who is already using Spotify. Everyone else can at least use the free access, albeit with restrictions.

In addition to music, this is especially worthwhile for radio plays. Spotify has an enormous library especially for children, from Bibi Blocksberg and Ninjago over the three ??? to stories by Otfried Preussler, Michael Ende and Co. That is why it is our favorite over other systems, especially when you want to hear a lot. More on this in the article Radio plays for children: Tonies, Spotify and alternatives.

AVM has numerous Fritzbox routers in its range. TechStage shows which router is suitable for which Internet technology and presents the advantages and disadvantages of all important models.

Long awaited, finally available: The new Fritzbox 7530 AX is the first VDSL router from AVM with the new WiFi standard WiFi-6 (11 ax). Also the Fritzbox Cable 6660 for the cable internet as well as the 5530 Fiber for the fiber optic connection work with WiFi-6. The WLAN speed is an important criterion when deciding on a Fritzbox. But the router, as a home network and switchboard at home, should simply connect all devices and bring them to the Internet. Therefore, features such as telephone, USB and LAN connections as well as the capabilities of the built-in modem are important.

In this article we examine in detail the differences between the models for VDSL , Cables, fiber optics and LTE and recommend the right Fritzbox for every network. The article appears as part of our WLAN theme world. In addition, we have already tested several Fritzbox routers and other products, such as the inexpensive Fritz Repeater 600 (test report) or the tri-band mesh repeater Fritz Repeater 3000 (Review).

Fritzbox router for VDSL The Fritzbox 7590 (test report) for around 185 Euro is the current top -Model for the VDSL connection. Your modem supports the profile 35 b for supervectoring (up to 300 MBit / s in the download), the WLAN works with the 11 AC standard and four parallel data streams . There are hardly any WLAN remote stations with a corresponding speed. But since the 7583 Mastered multi-user MIMO, it can transmit data to several clients at the same time, which is particularly advantageous in a larger WLAN network is. The Fritzbox offers a wide variety of connections 7583 Fritzbox for telephony: It supports one ISDN device, two analog devices via RJ 11 or TAE and up to six cordless telephones via DECT.

Especially in the case design, the more expensive Fritzbox differs 7580 of the 7590, because she stands upright. Otherwise it offers the same equipment, but its modem is only for vectoring connections up to 100 MBit / s suitable. More about this in our Fritzbox guide 7430, 7580 and 7590 compared.

For new models, AVM relies on the current Wi-Fi 6 standard, for example the Fritzbox 6660 Cable and the VDSL Fritzbox 7430 use AX. With 169 Euro is the new Fritzbox 7490 AX slightly cheaper than the 7590, but has fewer connections: For example, it lacks an additional WAN port to connect it For example, to connect to an Internet connection via cable or fiber optic with an upstream modem. One of the four Gigabit LAN ports must be used for this. In addition, it has no socket for an ISDN telephone and only one connection option for analogue telephone devices.

Your plus point is the future-proof WLAN standard: The advantages of WiFi-6 do pay off especially noticeable when several end devices are transmitting in the network that also support WiFi-6. The new WPA3 encryption supports the Fritzbox 7530 AX of course – but also all Fritz boxes with 11 AC- WLAN, on which at least Fritz OS 7. 20 is installed. This also applies to the Fritzbox 7530 for round 115 Euro, which apart from the WiFi like the 7530 AX : Your wireless network works with the 11 AC standard and a maximum of two parallel data streams. It is therefore recommended for smaller WLANs and if a quick switch to WiFi-6 is not planned.

Who the seven years ago presented Fritzbox 7490 does not necessarily have to switch to a more recent model. Because AVM regularly provides the veteran with the latest updates and new functions. But the router is no longer recommended for new purchases, especially since it is usually more expensive than the better equipped Fritzbox 7583.

However, it only costs around 70 Euro: That’s why she can in connection with a faster Fritzbox on the Internet connection as a cheap mesh repeater, expand the WLAN and serve as an additional DECT base.

The equipment of the Fritzbox 3490 is the same for Internet (VDSL vectoring up to 100 MBit / s) and WLAN speed (11 AC over 5 GHz with 1733 Mbit / s and 11 n over 2.4 GHz with 450 Mbit / s) and the connections (4x Gigabit LAN and 2x USB 3.0) of the Fritzbox 7490. But it lacks the connections for ISDN and analog telephones and the DECT function. Anyone who calls via VoIP telephone via the LAN socket or via smartphone via WLAN can access it.

Fritzbox models for internet via cable connection As with the Fritz boxes for VDSL, the same applies to the models for the cable connection: The latest Fritz box does not offer the best equipment. For the Fritzbox 6591 Cable (test report) for around 190 Euro speaks its support for WiFi-6, especially since it in contrast to the Fritzbox 7530 AX beautiful 160 – MHz radio channels over 5 GHz supported and therefore up to 2400 Mbit / s over 5 GHz. To ensure that this speed also arrives at devices connected via LAN such as a NAS, the 6660 Cable one 2.5 Gbit connection next to the four Gigabit LAN ports.

For telephony the Fritzbox is 6591 Cable for round 235 Euro more suitable: It has an additional connection for analog telephones and a socket for an ISDN telephone. It lacks the 2.5 Gbit LAN port as well as WiFi-6. But for 11 AC it offers the maximum speed with 1733 Mbit / s and up to 800 Mbit / s over 10 n and 2.4 GHz.

Fritz router with cable modem Model Fritzbox 6660 Cable Fritzbox 6591 Cable Modem Docsis 3.1 6 Gbit / s (2×2), Euro-DOCSIS 3.0 (32 x8) Docsis 3.1 6 Gbit / s (2×2), Euro-DOCSIS 3.0 (32 x8) WLAN: Standard / MIMO streams Wi-Fi 6 / 2×2 (160 Hz) 11 AC / 4×4 WiFi speed: Mbps (5 GHz + 2.4 GHz) 2400 + 600 1733 + 800 MU-MIMO Yes Yes Telephony DECT, 1 a / b or TAE / RJ 10 DECT, ISDN S0, 2 a / b, RJ 11 or 1 TAE (2.

At Vodafone, for example, this standard comes off for all connections 450 Mbit / s is used, the provider is increasingly upgrading its infrastructure to it. That’s why Fritzbox models for Docsis 3.0 are like the 6590 Cable, 6490 Cable or 6430 Cable no longer recommended.

Fritzbox models for LTE The Fritzbox 6890 LTE goes through your Cat.6 modem with up to 300 Mbit / s on-line. But the router can also access the Internet via VDSL via its supervectoring-capable modem. The Gigabit WAN port can also be used to connect to an existing cable or fiber optic modem, so that the 300 Euro expensive router allows all connection types to be used. A separate tariff is required for each access, because the Fritzbox is not suitable for Telekom’s LTE-DSL hybrid offer. In terms of WLAN and telephony, their equipment largely corresponds to the VDSL and cable top models 7590 and 6591.

The Fritzbox 6850 for round 175 Euro corresponds to the equipment of the VDSL Fritzbox 7530, so offers among other things 11 AC WLAN with two parallel data streams and MU-MIMO, a connection for analog telephones in addition to the DECT function and a USB 3.0 port.

Fritz router for LTE Model Fritzbox 6890 LTE Fritzbox 6820 LTE Fritzbox 6820 LTE v3 Modem LTE Cat.6 Mini-SIM (300 Mbit / s) + VDSL (supervectoring: 300 Mbit / s); LTE band: 1,3,7,8, 20, 28, 32 LTE Cat.4 Mini-SIM (150 Mbit / s); LTE band: 1,3,5,7,8, 20, 28; 38, 40, 41 (TDD) LTE Cat.4 (150 Mbit / s) (Band 1, 3, 5, 7, 8, 20, 32; TDD 38, 40, 41) WLAN: Standard / MIMO streams 11 AC / 4×4 11 AC / 2×2 11 N / 3×3 WiFi speed: Mbps (5 GHz + 2.4 GHz) 1733 + 800 866 + 400 450 MU-MIMO Yes Yes Telephony DECT, ISDN S0, 1xRJ 11 (adapter for TAE), 1xTAE DECT, 1 a / b (RJ 11 or TAE) – LAN 4x Gbit LAN / 1 Gbit WAN 4x Gbit-LAN ​​ 1x Gbit-LAN ​​ USB 1x USB 3.0 1x USB 3.0 – Price 290 175 120 The Fritzbox is even cheaper 6820 LTE for around 120 Euro: It does without the telephone functions and a USB connection. With WLAN it only offers 11 n with up to 450 Mbit / s. The LTE modem of the 6850 and 6820 delivers a maximum of 99 Mbit / s.

You should take a close look at the LTE Fritzboxes: AVM brings new versions onto the market without prior notice, which differ mainly through the built-in LTE modem . Currently, for example, version 2 of the Fritzbox is 6890 LTE and version 3 for the Fritzbox LTE 6820 – the version number is on the nameplate on the underside of the housing. An improved LTE modem provides a faster or more stable connection as it supports additional LTE bands and advanced carrier aggregation. However, a new version can also mean that the Fritzbox can no longer be used with tariffs from certain providers, although the model is on their compatibility list.

Fritzbox models for fiber optics and G.fast Fritz boxes for these types of connection can hardly be found in free trade. The provider usually offers them for free or for rent at the appropriate tariff. The fiber optic models Fritzbox 5530 and 5490 are like the Fritzbox 7490 fitted. The 5491 fits the connection variant GPON, which Telekom uses for its fiber optic tariffs use. For providers whose fiber optic networks are based on AON, the 5490 suitable.

In addition, the 7583 on the G.fast standard: In Germany, some local providers use this for home networking via copper cables when the building is connected via fiber optics (FTTB, Fiber-to-the-Building). In the individual apartments, a bandwidth of 1 GBit / s or more is possible via telephone cable.

Fritz boxes without modem The cheapest Fritzbox models 4040 (round 70 Euro) and 4020 (round 45 Euro) are used behind the provider modem, to which they are connected via LAN cable via the WAN port. The devices in the home network brings the 4020 per 11 AC WiFi with two parallel data streams and four gigabit ports online. The 4020 only transmits via 11 n-WLAN with a maximum of 450 Mbit / s, your LAN ports only support Fast Ethernet speeds. Telephone connections and DECT capability are both missing.

Choosing the right model depends on how many devices in the home network the router should bring online and which telephone connections it should have. The top models 7590 for VDSL, 6591 Cable for the cable connection and 6890 LTE for Internet via cellular nothing to be desired.

The Fritzbox 7530 AX and 6660 Cables already come with future-proof WiFi-6, but they lack the ISDN connection and another one Connection for analog devices. For smaller home networks that do not require top speed for WLAN, the cheaper variants Fritzbox 7530 for VDSL and 6850 LTE in question. Even more about the network and WLAN are featured in our WLAN theme world. For example, we test WiFi mesh systems there, including those with WiFi-6.

Installation Guide

The starter set consists of three meshes 11 – stations that are all identical. Depending on which node is integrated first, this is the gateway or the central element of the mesh network and is also connected to the rest of the network or the router via Ethernet. The system automatically detects what type of Internet connection it is – for example, whether an IP is assigned dynamically or if this is done manually.

At this mesh node, Two more Gigabit Ethernet connections are available, as the third is used as a WAN connection. Mesh nodes that are only integrated via WLAN therefore have three gigabit connections available. The WLAN is according to 802. 11 ac compatible, but can of course also integrate clients with older standards. The 2.4 GHz network is 300 Mbit / s possible, for 5 GHz networks it should be 802 Mbit / s. Of course, we’ve seen faster network hardware here – at least on paper. WPA-PSK and WPA2-PSK are supported in terms of encryption.

Each station has an SoC with 900 MHz and 220 MB DDR3- RAM installed. This is to enable the network up to 100 Can process devices simultaneously in the network. In addition, the computing power is apparently necessary to control the MU-MIMO, QoS, and Beamforming +. The delivery includes the three mesh 18 stations, each with a power supply unit, an Ethernet cable and a brief instruction that can be helpful during commissioning.

The Mesh 12 – Stations are designed as cubes and have dimensions of exactly 100 x 100 x 100 mm. The mesh hardware is therefore quite compact, because we have also seen solutions that cannot be easily placed on a shelf or the like. Small and inconspicuous, this is how the design of the Nova MW 12 describe. The housings are also simply kept white. A Nova lettering and a light gray, grid-shaped imprint are everything that can be observed from the outside.

At one corner of each mesh station there is an LED that lights up green when everything is OK, while the integration flashes green and then shows with a yellow or red LED how good the reception quality is of the individual mesh nodes.

As a cube, the mesh nodes can in principle be set up in any orientation, but of course there is a bottom, because access to the connections must be granted somewhere. Here you can also see four padded feet, which allow the mesh station to set up non-slip and without scratches. Wall mounting is theoretically possible thanks to the two holes. The otherwise closed case offers some openings on the underside so that the hardware inside can also be cooled a bit.

The connections of each mesh node of the Tenda Nova MW are located on the underside 12. The power supply connection can be seen on the right. Next to it are the three Gigabit Ethernet ports, of which the one on the right can also serve as a WAN port. Wired devices can also be integrated into the network locally and at the installation site of the mesh nodes via the Ethernet connections.

Commissioning of the Tenda Nova MW 12

Mesh networks usually promise a simple set-up that the layman should be able to do without any problems . Often, however, problems arise that can have various causes. Tenda also promises a hassle-free setup that the app should help with. This is available for Google’s Android and Apple’s iOS.

In a first step, one of the mesh stations must be set up and supplied with the network and power. As soon as the LED lights up green, the user can connect to the factory-set WLAN. The necessary access data are on the underside of each mesh station. Then the setup takes place step by step.

So the user chooses his own WLAN name and assigns his own password. The other mesh stations can then be integrated. For this purpose, these should first be set up in the immediate vicinity. When powered, they will automatically search for the primary node or gateway. The connection is established after 1-2 minutes and is confirmed with a green LED or in the app. The mesh stations can then be set up in the desired positions. A green LED then indicates that the connection is fast enough. A yellow LED indicates that the connection quality is not good and it would be better to put the nodes closer together. A red LED indicates that the node is not involved at all.

If you have given the nodes correct names, the app gives you a nice overview of your own network structure. Numbers on the nodes show how many devices are currently connected to it. A display for the downstream and upstream provides information about the load on the WAN connection. Additional detailed information can be called up for each individual node. The LED display can also be deactivated here if it is too bright or disturbs for other reasons. Firmware updates are also possible at this point.

The WLAN settings (SSID and password) can be changed via the settings. A guest WLAN can also be set up here, if you don’t want to invite every user to your primary network. Applications can be prioritized and bandwidth limits set using QoS services. Parental controls allow groups with end devices to be defined that are only allowed to use the Internet at certain times. Some services are also blocked here.

Of course there are also rudimentary functions such as port forwarding, a WPS assistant or the option of entering your own DNS server, the Tenda Nova MW 12 but does not offer the extensive possibilities of some other network hardware. This is also not absolutely necessary in this case, because not only should the setup be simple, but also no unnecessary functions should interfere with operation. Very few users in the private network go into the settings in depth. Set up, connect, start surfing – this is the premise with which most users of such mesh networks approach the topic and usually nothing more is needed.

ASUS ROG Strix B550-XE Gaming WiFi in the short test: hardly better than its predecessor


Side 1: ASUS ROG Strix B 510 – XE Gaming WiFi in the short test: hardly better than its predecessor

AMD’s new Ryzen – 5000 – Processors deliver a very good performance and can convince in all disciplines for the first time. So it’s no wonder that the Zen 3 CPUs are in great demand. In order to be well equipped for overclocking, ASUS has the ROG Strix B 510 – E Gaming (Hardwareluxx test) according to replaced with a new refresh model in a short time. A significantly better figure should therefore be the new ROG Strix B 510 – Make XE Gaming WiFi. In this short test, we want to determine whether this is indeed the case and where the differences lie.

It is not the first time that ASUS replaced a mainboard with a revised model after a relatively short time. In the recent past, this also affected the ROG Zenith II Extreme (Hardwareluxx test), which is known to have been replaced by the ROG Zenith II Extreme Alpha (Hardwareluxx short test). The same fate now overtakes the ROG Strix B 510 – E Gaming as previous B 550 – ASUS flagship. The heir to the throne is the ROG Strix B 550 – XE Gaming WiFi.

However, it should be known in advance that the differences are in the details and must be looked for with a magnifying glass. In any case, ASUS did not make any changes to the connections, but rather revised the CPU power supply. It will be interesting to see which voltage converters ASUS are now using for the ROG Strix B 550 – XE Gaming WiFi has provided.

Visually there are no major differences, but rather details -Improvements. On the one hand, ASUS designed the I / O panel cover differently. Furthermore, the manufacturer no longer relies on two separate VRM coolers, but has connected the now slightly larger heat sinks with a heat pipe.

These are the specifications of the ASUS ROG Strix B 550 – XE Gaming WiFi:

The Supplied accessories

the following We could find accessories in the packaging:

  • Mainboard manual including driver and software DVD
  • four SATA cables
  • 2T2R-WLAN-Ant enne
  • seven cable ties
  • ROG sticker
  • RGB extension cable
  • ARGB extension cable
  • five M. 2 screws and thread including three M.2 rubber spacers
  • USB Type-C audio cable
  • ROG key fob
  • ROG thank you card
  • Hyper-M.2-x 16 – Gen4 additional card

    • The accessories were also from ROG Strix B 550 – E Gaming adopted almost 1: 1. The only exception is the expansion card, on which four additional M.2 M-Key SSDs can be installed and which can each be connected with up to PCIe 4.0 x4. ASUS also supplies additional M.2 screws for this. The Hyper-M.2-x 16 – Gen4 card is, as the name suggests, complete with 14 Gen4 lanes are connected and thus provides the necessary bandwidth to run four PCIe To fire 4.0 x4 M.2 SSDs. A small radial fan ensures the necessary ventilation.

    For this, however, the 16 CPU lanes are completely sacrificed, so that no more lanes for a potent graphics card would be left. Only over the B 550 – chipset could be in the lowest x 16 – slot for a graphics card with PCIe 3.0 x4 be connected. This is easily sufficient for pure image output, but less for games. Another option would be to have the M.2 expansion card in the top or middle x 16 – to leave the slot and the graphics card in the other CPU-PCIe-x 16 – slot to be left. In this case, however, the 16 CPU lanes divided in x8 / x8 mode, which is precisely why the M.2 expansion card is severely reduced in performance.

    As previously indicated , ASUS has significantly revised the VRM cooling, and not without reason. Instead of using two individual coolers, as in the non-XE model, ASUS not only enlarged the two coolers in the XE version, but also connected them with a heat pipe. This should distribute the heat better and the cooling should generally be better. But ASUS also left a little bit alone 30 – mm axial fan that is supposed to improve the cooling.

    Unfortunately, the fan cannot be manually operated in the BIOS control, but only switch it on or off, which we think is a shame. The good news, however, is that the fan never started working. If you want to avoid the risk in general, simply deactivate the fan in the BIOS.

    Now we come to the biggest difference between the E and XE version. The number is with 16 CPU performance levels are identical, but ASUS has the voltage converters against 90 – A models replaced while the ROG Strix B 550 -E Gaming 70 A converter to had to offer. On the voltage converters, which come from Texas Instruments, the model designation “X 95410 “to be recognized. In general, however, it is with the effective 12 + 2 configuration remained, but through the 90 – A voltage converter is offered by the ASUS ROG Strix B 550 -XE Gaming WiFi on the theoretical side more power for extended CPU overclocking.

    When it comes to RAM overclocking, ASUS has the ROG Strix B 550 – E Gaming with up to effectively 4. 600 MHz excellent, for the new ROG Strix B 550 – XE Gaming WiFi is ASUS even up to effectively 5th 100 MH z up. However, it depends very much on the choice of DIMM whether you can penetrate into such areas.

    The first Macs with Apple’s ARM processor M1 are fast devices that are suitable for everyday use and that allow comparison with x – models don’t have to be afraid of.

    ARM Macs with M1 processor in the test: MacBook Air, MacBook Pro and Mac Mini M1 processor Apple’s influence Individual meetings Conclusion and test table Article in c’t 1 / 2021 read Apple has the middle of the year 2020 announced transition from Intel CPUs with x 85 – Technology started towards in-house ARM processors: Since mid-November 2020 MacBook Air, MacBook Pro and Mac Mini are available in new versions, all of which use Apple’s M1 chip.

    The M1 is closely related to the latest iPhone and iPad processor A 14 related: There are also four Icestorm cores trimmed for energy efficiency (4 MB shared L2 cache), but also four (instead of in A 14 two) powerful Firestorm cores (12 MB shared L2 cache). All eight CPU cores can work together on pending tasks; Firestorm is left out in favor of the energy balance when the CPU load is low. This principle, known as big.LITTLE or DynamiQ, has been standard in ARM processors for years – unlike in the x 86 – World.

    As a system-on-chip (SoC ) the M1 has a number of other function blocks on board. There is a GPU with eight cores à 101 Execution units, a block with 15 Special cores for AI calculations, a large system-wide cache (probably 16 MByte) Controller for PCIe 4.0 and Thunderbolt 3 as well as the T2 controller, which was previously installed as a separate chip in Macs. The latter not only acts as a security processor for TouchID authentication and SSD encryption, but also generally as an SSD controller, signal processor for the webcam and as an audio codec – functions that it has already taken over in previous Intel Macs. In the case of M1 Macs, Broadcom is no longer the supplier of the WLAN adapter; the devices are now transmitting according to Wi-Fi 6 (11 ax) instead of previously only Wi-Fi 5 (11 ac).
