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.

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.

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.

Page 1: Tenda Nova MW 12 in the test: Mesh system at an attractive price
In the mesh network hardware sector, Tenda is unlikely to be a household name for many, even though the company has been active as such for some time. In the past few months there has been more attention in this country – especially with regard to cheap, yet fast mesh hardware. One wants to have left the established providers behind. We have the Tenda Nova MW 11 looked more closely as a beginner’s solution.
Tenda is in the year 2012 partnered with Broadcom and has become a key partner in China. The company has been using Broadcom’s chipsets since then and wants to be able to guarantee a certain degree of compatibility and performance. In addition to the mesh products, routers, switches and much more in the area of network hardware are also available.
The Nova MW 12 with its three stations covers an area of 500 m² from. The set consisting of three stations can be extended to 12 Mesh node can be expanded and then covers up to 2. 000 m² from. With the help of the Tenda WiFi app, the stations can be managed and, if required, a guest network can be set up or a child lock can be activated.
Now we come to the Nova MW 12 or to the technical data of the mesh system:

Scope of delivery
3x mesh 12 stations three power supplies Ethernet cable 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.

In this tutorial, we’ll install Alexa Smart Screen SDK on a Raspberry Pi 4 to essentially “make” our own version of the Echo Show. We’ll nickname this project, “PiShow.” This project is possible with the Amazon Alexa Smart Screen SDK, in addition to the Alexa Voice Service (AVS) SDK discussed in our previous article, How to Build an Alexa Speaker with Raspberry Pi.
Caveats about PiShow
PiShow is not intended to be a replacement for the Echo Show. While many of the Echo Show capabilities are included with this version, significant capabilities including the ability to play videos natively were intentionally excluded from this build.
This smart screen version of AlexaPi does not include the vocal wake word trigger “Alexa.” The user will press the ‘A’ key when speaking to Alexa.
PiShow cannot launch with VNC active. VNC must be disabled on the Raspberry Pi.
Music – The user can pause music on a Pi touchscreen. Music capabilities are the same as described in the AlexaPi article.
Alexa Skills are available on PiShow, and any visual screens within an Alexa Skill are also visible on PiShow. Furthermore, touchscreen functionality is enabled for Alexa Skills.
If you are using a touchscreen, and you tap the screen while Alexa is speaking, she will stop speaking. This is the same behavior on the Echo Show.
Why Build a PiShow?
In our previous article, we addressed the cost differential of purchasing the AlexaPi project components vs. an Echo Dot. In this post, we fully disclose that it is less expensive to purchase an Echo Show vs. the components for PiShow.
If you already own a Raspberry Pi and a touchscreen, this could be a fun weekend STEM project. The fun is in the making and learning about how voice technology works behind the scenes.

PiShow Setup and Install
1. Important: Complete the AVS installation as detailed in our previous article, How to Build an Alexa Speaker with Raspberry Pi.
2. If your AlexaPi is currently running, press Ctrl-C to stop the script. Speaker, mic and power should still be connected.
3. Attach your screen : I added a 7” Raspberry Pi Touchscreen for the PiShow version. But you could use a third-party touch screen that connects via either HDMI or via the GPIO pins. You can find such screens for as little as $23 on Amazon. If you use a screen that’s non-touch, you can’t use those features.

4. Open a Terminal.
5. We will start by creating the folders and installing the libraries and apps we will need for PiShow. Enter the following commands.
6. Next, we will install PortAudio to record microphone data.
cd third-party
wget -c http://www.portaudio.com/archives/pa_stable_v190600_20161030.tgz
tar zxf pa_stable_v190600_20161030.tgz
cd portaudio
./configure --without-jack

When the make install is complete, there should be no error messages on your screen.
9. Copy the config.json file from the AlexaPi project (/home/pi/) to the Install folder and generate the AlexaClientSDKConfig.json file.
14. You can also save a backup copy as AlexaClientSDKConfig_backup.json
(Image credit: Tom’s Hardware)
15. Close your Text Editor.
16. Create or modify your /.asoundrc file.
cd
sudo nano ~/.asoundrc
17. Add the following lines to ~/.asoundrc
pcm.!default {
type asym
playback.pcm {
type plug
slave.pcm "hw:0,0"
}
capture.pcm {
type plug
slave.pcm "hw:1,0"
}
}
(Image credit: Tom’s Hardware)
18. Press Ctrl-X, Y, and Enter to save your ~/.asoundrc file.
19. Test your progress so far.
cd $HOME/sdk_folder/sdk-build
PA_ALSA_PLUGHW=1 ./SampleApp/src/SampleApp
./Integration/AlexaClientSDKConfig.json DEBUG9
20. Similar to the authentication you completed during the AlexaPi project, in the Terminal, scroll up to find your code, then navigate to http://amazon.com/us/code and enter your code.

23. This AlexaPi works slightly differently from the original AlexaPi project in that you’ll have to type ‘t’ followed by the Enter key before speaking to Alexa. Try it now. Press ‘t’ enter and say, “What time is it?”
If Alexa provides the time, then you have successfully completed installing the AVS Device SDK sample app. Congratulations!
24. Press Ctrl-C to stop the sample app.
25. Next, we will download and ‘make’ the APL Core Library. The last command in this sequence ‘make’ took approximately 15 minutes to complete.
cd $HOME/sdk_folder
git clone --single-branch --branch v1.4.1 git://github.com/alexa/apl-core-library.git
cd $HOME/sdk_folder/apl-core-library

Next, we can test our PiShow app. (If you are using VNC, you will need to stop and disable VNC in order for the app to launch.)
Run PiShow
28. Open File Manager and navigate to: /home/pi/sdk_folder/ss-build/modules/GUI/index.html
(Image credit: Tom’s Hardware)
29. Open index.html with your Chromium browser by double-clicking on index.html
(Image credit: Tom’s Hardware)
30. Go back to your Terminal and enter the following commands to start your PiShow.
cd $HOME/sdk_folder/ss-build
PA_ALSA_PLUGHW=1 ./modules/Alexa/SampleApp/src/SampleApp -C
$HOME/sdk_folder/sdk-build/Integration/AlexaClientSDKConfig.json -C
$HOME/sdk_folder/alexa-smart-screen-sdk/modules/GUI/config/SmartScreenSDKConfig.json -L INFO
31. You may need to authenticate the PiShow sample app as you did during step 22. If so, scroll up to find your code in the Terminal, then navigate to http://amazon.com/us/code and enter your code.
32. Go back to your Chromium browser and you should see the message “Press and Hold “A” then Speak”
(Image credit: Tom’s Hardware)
33. Give it a try! Quick note: index.html in Chromium must be the active window for PiShow to work. Hold down the ‘A’ key while you say, “Tell me the weather.”
Congratulations! You have made your PiShow!
(Image credit: Tom’s Hardware)
Always use the same process: With /home/pi/sdk_folder/ss-build/modules/GUI/index.html as the active window, hold down the ‘A’ key while speaking to Alexa. You do not need to say the wake word, “Alexa.”
Things to Try on your new PiShow
“Play Music” – If using the touchscreen, you can pause the music by tapping the pause button on the screen.
“Tell me a joke.”
“Open Big Sky” – Weather app with great graphics.
“What does Planet Earth look like?”
“Enable Space Station”
To stop PiShow, go back to your Terminal and press Ctrl-C.
(Image credit: Tom’s Hardware)
If you turn off or reboot your Pi, you can restart PiShow with the Terminal command:
cd $HOME/sdk_folder/ss-build
PA_ALSA_PLUGHW=1 ./modules/Alexa/SampleApp/src/SampleApp -C
$HOME/sdk_folder/sdk-build/Integration/AlexaClientSDKConfig.json -C
$HOME/sdk_folder/alexa-smart-screen-sdk/modules/GUI/config/SmartScreenSDKConfig.json -L INFO
If you intend to purchase a online beauty product, Google gives you the opportunity to see how they fit your body. The function is available thanks to the collaboration with ModiFace and Perfect Corp
by Lorenzo Tirotta published 19 December 2020 , at 15: 31 in the Technology channel Google
Buying products online has now become a consolidated reality for millions of people, thanks to the convenience and an unprecedented shopping experience . Today the online sales methods have multiplied like wildfire, even in the apparently more difficult sectors such as clothing and cosmetics which, thanks to technological innovation, do not always make physical presence in the store necessary.
According to some surveys the 73% of US citizens, for the Christmas holidays are willing to shop online . An exponentially increasing phenomenon also characterized by the ongoing pandemic that limits physical purchases. Although the internet offers us this great possibility, a large portion of the population still prefers to shop in physical stores to take full advantage of expert advice, try products live or simply help small shop owners who don’t have an online site.
This is how Google allows you to try products virtually
A everyone at least once has happened to buy a product online and be disappointed by the final result once tried. With clothing and cosmetics is a risk to be taken into account , since trying it on the body first is a crucial step for the buyer. Google worked on just that, and through its app will make it possible to try tricks such as eye shadows, lip glosses and lipsticks of the biggest cosmetic brands directly from the screen of your PC or smartphone or tablet .
The function is made possible thanks to the collaboration of data partners such as ModFace and Perfect Corp and technology offered by Google. Through this new function it will be easier to find a perfect match with the tone of our skin. Through the app it is possible to quickly try each shade of the collections of famous brands such as L’Oreal, MAC Cosmetics, Black Opal and Charlotte Tilbury.
Google finally offers the possibility of receive advice from industry experts of products you want to buy directly from the app. A fundamental tool for concluding an online purchase, implemented thanks to the work of the Shoploop team .

Iliad has revolutionized the fares market mobile rechargeable by introducing a new way of making tariffs. In recent times the company has produced new offers but has not abandoned the old ones that always remain activable even if hidden. Here they are all.
by Bruno Mucciarelli published 19 December 2020 , at 00: 01 in the Telephony channel Iliad
Iliad is the mobile operator that has literally exploded since it arrived in Italy. It immediately captured the attention of the public by revolutionizing the world of telephony in its way with low-cost rates but with almost unlimited bundles. Since its arrival, the other operators have begun to offer users increasingly cheaper rates with the formula of calls and SMS without limits but with variable prices based on the quantity of Giga.
Iliad: here are all the offers that can be activated
The operator after a few years from his debut continues in the proposition of always interesting offers that even allow you to have up to 50 GB of data traffic to surf without speed limits and with still calls and SMS without limitations. However, alongside this offer there is also the older one that is currently hidden by Iliad on its website. Yet it is that can be fully activated by users who can save even more if you are satisfied with a bundle with 12 GB of data traffic per month.
To find the Giga 40 it is necessary to move from the homepage of the official website Iliad , the operator offers the tariff ” Giga 50 ” which is basically the most important and convenient rate of the moment. At a cost of 7. 99 ?? in fact it is possible to have 50 GB of data traffic to surf at unlimited speeds with also unlimited calls and SMS.
GIGA 50
Unlimited minutes of calls to all national fixed numbers and furniture
Unlimited SMS to all
50 GB of data traffic under the 4G network with Hotspot included
COST: 7. 99 ?? per month
WHERE TO ACTIVATE IT: ONLINE or STORE
Activation COST + SIM: 9. 99 ??
Next to this the only item offer is proposed which allows you to have unlimited calls but practically without data for internet browsing. Here is specifically what it provides:
VOICE
Unlimited Minutes of calls to all national fixed and mobile numbers
Unlimited SMS Towards all
40 MB of traffic data under 4G network with Hotspot included
COST: 4. 99 ?? per month
WHERE TO ACTIVATE IT: ONLINE or STORE
Activation COST + SIM: 9. 99 ??
But alongside these two offers, Iliad still proposes the old Giga 40 which, although not visible on the website directly, can still be activated. In this case from the Giga 50 it is possible, scrolling the whole page up at the bottom, find the offer from Giga 40 that is with 40 GB for the price of 6, 99 ??. At this point, just tap or click on ” Discover other offers ” . From here you enter the Giga offer page 40 which provides therefore specifically:
GIGA 40
Unlimited minutes of calls to all national fixed and mobile numbers
Unlimited SMS Towards all
40 GB of data traffic under the 4G network with Hotspot included
An amendment to the Budget law would be ready to introduce a so-called “ digitization kit ”, an experimental measure for families with ISEE income lower than 20 thousand euros for a smartphone connected to the internet and a subscription to two press organs for a year. Here are the details.
by Bruno Mucciarelli published 19 December 2020 , at 10: 01 in the Telephony channel
A ‘citizenship’ smartphone. It is the new idea of the Government for all families with an ISEE lower than 20 thousand euro and therefore I cannot always afford an internet subscription or a connected mobile phone. In this case the ” Phone Bonus 2020 ” which will be called more specifically digitization kit , is a novelty that should be introduced in the new Budget Law with a specific amendment ready to go to the vote in the next few days.
Phone Bonus 2020: what it consists of and to whom it will be
In this case if the proposal should go through here that to citizens with an ISEE lower than 20. 00 0 ?? it would be “ on loan for use ” a telephone connected to the internet, with a subscription to two press organs, the pre-installed IO application and above all the internet connection for one year. A benefit that would be granted to only one person for each family unit. In this case, in order to access the digitization kit, the Spid and, of course, compliance with income requirements. To finance the measure, an allocation, again through this fund, of 20 million of euro for the 2021.
All this is added to the so-called ‘Fund for technological innovation and digitization and continuity of the management of the Covid alert system’ and aims to reduce, as far as possible, the phenomenon of the digital divide. For this reason the idea is to at least try to allow even those who cannot, a smartphone connected to the internet and which allows them to stay in touch with the world. In this case the most important stakes for accessing the possible free loan proposal for the smartphone are those having the ISEE lower than 20 thousand euros but also of have no internet connection contract or even an active mobile phone contract.
The year 2020 that is about to be concluded has highlighted an important digital divide that characterizes the whole of Italy. Lo smart working as well as DAD (Distance Learning), have partially recognized the limits of Italians in this sense. The State is trying to limit or reduce these situations by proposing the various PC bonuses and Internet or even the state cashback . Being able to have a PC for those who have an ISEE lower than 20. 00 0 euro and without Internet connections with speeds of at least 30 Mbit / s and now even a connected phone can undoubtedly mean a start to a digital improvement albeit a small one.

Intel today started the process of discontinuing its Intel Core Avengers Edition processors , which were released a few months ago and, despite their potential appeal, don’t seem to have seen big sales, especially given the low popularity these chips have had on the internet.
This discontinuation has been officially announced in a PCN (Product Change Notification), in which we can see that once these processors are discontinued, the recommended product is still the standard chip , remember, the Intel Core Avengers Edition processors never had anything special beyond out of the box, so internally Intel may have moved some processors from some boxes to others for sale.
This PCN with the number 117894 – 00 mentions the day 16 December as a common date for the four phases of this process , which are the beginning of the discontinuation of the support of the product, the deadline for distributors to order this product, the date orders become non-cancellable, and the final shipping date.
Be that as it may, this document finally goes on to mean that Intel completely ends manufacturing, distribution and support for Intel Core Avengers Edition processors.

Google’s operating system for internet of things is facing certain death. The company declared the plan for dismantling the project.
by Nino Grasso published 18 December 2020 , at 18: 51 in the Operating Systems channel Google Android
Google planned the deletion of Android Things , a version extremely lightened by Android designed for smart home devices. The operating system has never reached great levels of adoption and never achieved great success, so Google’s decision doesn’t surprise much . This is one of the many projects canceled by the company, whose enormous success hides numerous failed and ended experiments in a huge cemetery full of finished projects.
Android Things originates in 2015, inside of a project that was called Brillo and which intended to create an operating system at the base of the world of the Internet of Things. A year later, Google relaunched the initiative under the name Android Things, which evolved for introduction on more complex devices, such as connected speakers, security cameras or routers. At the base of the redesign was the need to offer a platform known to developers.
Based on Android and probably similar development dynamics, the operating system would have captured the attention of the insiders, at least according to Google’s initial idea. In reality, however, it did not go quite like this . In the 2018 some (few) products, such as smart speakers or smart displays, have relied on Android Things , but it didn’t last long. At the beginning 2019, in fact, Google announced new plans for the operating system.
Two years later, however, the news of the cancellation of the project arrived. The Android Things Console, where developers can upload device updates, will no longer accept non-commercial projects starting January 5th 2021. One year later, on January 5th 2022, “the console will be completely disabled and all project data will be permanently deleted” , Google pointed out. The developers therefore have about a year to suspend all their projects and decree their end without the possibility of second thoughts.
This is a an unglorious end for a project that was introduced into a very sparkling market , such as that of home automation and Smart Home, which is growing above all in terms of interest by people and potential users. However, Google has not managed to make its mark with respect to the many proposals already present, and therefore Android Things is destined to die with unusually fast timing.
Although it is possible that we have never heard of Android Things , we have all seen the advantages and disadvantages of Internet of Things or IoT devices, and it is that Android Things was a platform launched by Google in 2018 and it came as a much simpler operating system , designed for these devices, which promised security updates, an established SDK, and access to the Google Cloud platform.
However, the devices that made use of Android Things were significantly larger, more expensive, and required more power than the competing IoT devices , based on other platforms, so this is a disadvantageous platform.
Google decided last year to turn Android Things into a platform for smart speakers and displays , something that could have had some success if it weren’t for the detail that Google didn’t even bet on Android Things at any time , preferring the Google Cast platform for these purposes.
The developer console of Android Things will stop accept new projects from January 5, 2021 , day on the that updates can only be released for applications already published until January 5, 2022, where data and projects will disappear forever.

Python has established itself as the language of choice for machine learning, artificial intelligence and data science in recent years. There are good reasons for that.
Of
Marcus Hanhart Denis Stalz-John This is why Python has blossomed into the language for machine learning Easy to learn Expand the language Conclusion Read article in iX 1 / 2021 Social networks, the Internet of Things and the further development of hardware, software and infrastructure There has been a significant increase in the amount of data stored in recent years. By intelligently analyzing this data, companies gain a competitive advantage over their competitors. In addition, data science is finding its way into university research – not only in computer science, but also in subjects such as biology, physics and sports science. Modern technology makes it easier to record a wide range of data, for example movement profiles of athletes. The use cases in the area of data analysis thus range from productive use in companies to trying out in student projects.
This wide range of application scenarios creates a demanding requirement profile for the development environment. In the business world, the practices of Continuous Integration and Deployment (CI and CD) and DevOps are often lived. The programming languages used are usually object-oriented, can be modularized and have a suitable test framework. In research, however, software engineering is in the background. The main thing here is that the programming language used has a simple syntax and can be learned quickly. Scientists have to implement evaluations efficiently, whereby it is often sufficient to develop a script instead of extensive software.
Regardless of the user, when working with data it is important that intermediate results are displayed dynamically as well Have the final results visualized interactively. This helps to improve the model and to check the feasibility of the evaluation. Python has established itself as the language of choice. Jupyter notebooks support users to analyze and visualize data interactively.

In addition to SpaceX, other companies with large satellite constellations also want to provide better Internet access. OneWeb has now launched dozens of satellites.
(Image: OneWeb)
The European rocket operator Arianespace has sent further satellites into space for better Internet supply on earth. On Friday evening (local time), a Russian Soyuz rocket took off from the Vostochny spaceport in the far east of the country, as the Russian space agency Roskosmos announced on Twitter. On board were 36 satellites from the British communications company OneWeb.
Further starts planned It was not the first start of this kind: Overall will be 672 Satellites put into near-earth orbit are now 110 above, Arianespace announced . The satellites are intended to provide a high-speed network for the Internet on earth, by sea, on land and in the air. In addition, further starts are planned until the end 2022.
The OneWeb group, which has been saved from bankruptcy, plans to start commercial services by the end of 2021. The competition is fierce: Billionaires like Tesla boss Elon Musk with his space company SpaceX also want to set up satellite networks for Internet supply. The Vostochny spaceport around 2022 kilometers east of Moscow was only 2016 opened.
You’ll likely use your headphones more than any other piece of hi-fi equipment. At any one time in the What Hi-Fi? office at least half of us are using them, and not exclusively due to our questionable personalities (though this figure will spike, depending on who’s talking).
We’re well aware there is personal preference in what you want from your headphones – even we aren’t precious enough about hi-fi to assume the success of companies such as Beats is reliant only on good marketing. But by and large there’s no reason you ought to expect a radically different performance to that of your amplifier and speakers. (We’ve also suggested best songs to test your speakers.)
You may already have your own playlist to test equipment before you buy it – if not, it’s a worthwhile exercise – but we’ve put together this collection of ten tracks to help highlight what we believe to be the most important aspects of your headphones’ performance. If they’re found lacking in any department, you may want to consider an upgrade.

Best headphones 2020: all styles, all budgets
Explosions in the Sky – Wilderness
To test overall balance
Why? Balance isn’t always an easy one for headphone manufacturers to get right. Quite often we find them overloading the bottom end in an overzealous attempt to keep their product from sounding lightweight or rolling off the treble to avoid any sharpness nearer the top of the frequency range.
In order to test the overall balance, you want a track that covers as much of the frequency range as possible. You’ll get that from a lot of orchestral works – but more contemporary pieces can work as well, such as this from Explosions in the Sky. There’s plenty of low-end heft in Wilderness‘s percussive pulse, while some of those guitar harmonics will reach high into the treble frequencies.
View Explosions in the Sky at Amazon
Fleet Foxes – Fool’s Errand
To test midrange quality
Why? By and large, the midrange is where you’ll find your vocal lines: pretty important, then. Clarity is, of course, a primary concern, as are stability and warmth. If there isn’t enough midrange support from lower frequencies, vocals can sound thin and lack human quality.
Finding a track with a clear, prominent vocal line is all you need do, but it’s even better if it includes such gorgeous vocal harmonies as Fool’s Errand from the latest Fleet Foxes record. Robin Pecknold’s voice ought to soar, flanked by those luscious harmonies without disappearing into them.
View Fleet Foxes at Amazon
Darkside – Paper Trails
To test bass control
Why? We mentioned some brands’ tendency to skew the balance toward the bottom end, which we understand suits a certain section of the market. But if that’s what you like, it is perhaps even more important those bass frequencies are articulate and suitably agile.
It isn’t enough for your headphones to make your earlobes wobble if you can’t actually hear what’s going on down there. A track with a moving bassline will either drive or confuse a performance, depending on the aptitude of your kit. Darkside’s Paper Trails has the added benefit of testing a vocal line deep into the frequency range, which will really highlight the clarity of the bass – or lack thereof.

Pharoah Sanders – You’ve Got to Have Freedom
To test treble quality
Why? Coarseness in treble frequencies is probably one of the first things you’ll notice in headphones because it’ll make your ears hurt. If that’s happening once you’ve given your headphones a day or two to run in, you’ll end up wanting to bin them altogether. But sometimes it can go the other way – perhaps in an attempt to rid a performance of any sharpness, manufacturers will roll the frequency range off at the top end.
Either way, you aren’t getting the rich treble frequencies you and your ears deserve. This particular track from Pharoah Sanders finds his saxophone in full-on attack mode. Without making your ears bleed, it ought to sound like a mother goose being prodded with a knitting needle, and you should accept nothing less.

20 of the best albums of 2020
Havergal Brian – Symphony No1 in D Minor (The Gothic)
To test level of detail
Why? It’s rare we really criticise a product for lack of detail alone, but when we hear something particularly insightful it can really make a difference. The term itself is pretty self-explanatory: it’s about digging deep into what is being performed, rather than how.
Large-scale orchestral pieces, with a grand range of instruments and timbres, will highlight just how much insight is being delivered. This particular symphony, written by Havergal Brian, is a veritable behemoth, spanning the piccolo to the timpani via two harps and a children’s choir. Live recordings are another decent test: hand-claps are one of the more difficult sounds to reproduce.
View Havergal Brian at Amazon
John Martyn – Small Hours
To test space
Why? Space may appear a peculiar concept when it comes to sounds being played directly into your ears, but a claustrophobic performance can be the enemy of deeper listening. You don’t want instruments to sound detached from one another, but each line should have space to breathe.
Again, live performances are a good test as to whether your headphones are able to judge the size of an auditorium – or you can go a step further with this album closer from John Martyn. It was recorded outside, so there is no excuse for Martyn’s guitar to sound at all boxed in.
View John Martyn at Amazon
BadBadNotGood – Speaking Gently
To test rhythm and timing
Why? Anyone who was ever in a school band will know how infuriating it is to play with somebody who can’t keep time – if you didn’t know that, it was probably you. The same goes for hi-fi, and your headphones should be able to make sense of polyrhythm just as adeptly as they lock into a rigid 4/4.
This particular track from BadBadNotGood’s album IV offers a simple, solid beat as it opens, before sprawling into a freer percussive mindset. Timing also feeds into how instruments interact, how they question each other and then answer. If the performance sounds loose, disorganised or dull, it’s probably down to timing.
View BadBadNotGood at Amazon
Arvo Pärt – Tabula Rasa
To test dynamic range
Why? As good as your four-year-old nephew may be at playing the recorder, you probably don’t want your headphones to play like they’re at a school assembly. A dearth of dynamic range will give you a flat performance, sometimes sounding almost like a rehearsal, undermining any emotion on the original recording.
Pick a piece where small- and large-scale dynamics fluctuate as they do in Arvo Pärt’s Tabula Rasa and you’ll hear whether your headphones are up to the job. It’s often the smaller-scale dynamics that make the greatest impression: those are what will give voices their expression, which will be especially important if you use your headphones for watching films and TV as well.

Ólafur Arnalds – Ljósi∂
To test subtlety
Why? Getting you out the door and enthused for your run is one thing, but if you use your headphones for anything else then a little subtlety and restraint will be as important as that drive.
This Ólafur Arnalds piece, from his album Found Songs, is a lesson in refinement, with piano keys wanting to be stroked rather than hammered, violin weeping rather than in the midst of a full-on gin-sob. If your headphones can render this as well as they do Black Sabbath, it’ll really pay off in the subdued moments of tracks before they end up letting fly.

Joe Goddard – Lose Your Love
To test excitement, enthusiasm and drive
Why? All of this may seem like arbitrary box-ticking if your headphones’ performance doesn’t make you want to move. Really, this kind of enthusiasm and drive is a combination of timing, low-end stability and a good grasp of dynamics – but we have heard products seemingly adept at each of these that ultimately fail to enthuse.
You can insert your favourite groove-laden track here, but we’ve opted for Lose Your Love from Joe Goddard’s 2017 album Electric Lines. If your headphones are doing it right, you’ll be anticipating the beat dropping, and you’ll look unhinged to your co-workers as soon as it does.

News from the cemetery of Google projects: Android Things, an operating system for embedded systems and the Internet of Things, is apparently about to be finally over. From January 5th 2021 the Android Things Dashboard will no longer accept new projects, updates for existing deployments will run on January 5th 2022 from.
Silence in the forest since last release Originally, Google had promised to deliver at least three years of updates (purely arithmetically: by May 2021), but the last release has already hung off (August 2019). A look at the release page reveals that there are no more waiting in the pipeline. Apparently Google wants to bury the project in silence, an official statement beyond the dashboard deadlines in the FAQ is – at least so far – not available.
Android for every thing? With Android Things, Google had gone beyond the smartphone and had taken “an aggressive step into the world of hardware control”, as hardware experts said Tam Hanna had commented on the first announcements. Google launched Android Things with the official release in May 2018 after a year and a half of development, then there was nothing to hear for a long time. Android Things was intended as the successor to the less successful Brillo (from ).
Already in February 2019 the Californians cut the initially very broad approach as a large IoT platform with Android for Everything and rowed back a more modest project with a continued existence as Android Things SDK as a platform for experimentation for hobbyists and OEMs (original equipment manufacturers, i.e. manufacturers of hardware components). At that time, Google referred commercial customers to Cloud IoT Core and Cloud IoT Edge, the in-house cloud offerings for everything to do with the Internet of Things.
Deadlines in the FAQ stone chiseled The original support promise for updates for three years can still be read in the first release message in the Android developer blog. The frozen release plan had been fueling the assumption for some time that Google discontinued the project internally after the fall 2019. This is underpinned by an FAQ entry, which now sets the deadlines in stone.
