The wireless network should be up to four times faster. But what is left of it in practice on Apple devices and what are the requirements?

Fast WLAN: This brings Wi-Fi 6 to iPhone, iPad and Mac Transfer more data Better to radio in parallel Some with neighbors Save energy Continue to transmit Combine several networks Check data paths What can be expected? Available hardware and Apple devices with Wi-Fi 6 in the test Item in Mac & i 6 / 2020 read WLAN has become indispensable, because most Apple devices do not have Ethernet sockets, but only go to the Internet wirelessly. In addition, there are more and more household devices such as televisions, radios and smart home devices that use WiFi. However, if you live in an apartment building in the city with many radio cells in the neighborhood, the bandwidth for video streaming or video telephony is sometimes no longer sufficient because the base stations have to constantly wait for each other. The new Wi-Fi 6 standard aims to address these problems. On the one hand, it should make WLAN faster and, thanks to new technologies, more efficient.

Instead of the new standard, IEEE 802. 11 ax, the Wi-Fi alliance has decided to name it Wi-Fi 6. In Germany it is sometimes called WLAN 6. At the same time, retrospectively 802. 11 ac in Wi-Fi 5 and 802. 11 n renamed to Wi-Fi 4.

Transfer more data Wi- Fi 6 initially increases the maximum gross data rate by just under 40 percent, through a higher modulation level (more on this in a moment). Theoretically possible with Wi-Fi-5 / 192. 11 ac 6900 Mbit / s, provided that eight MIMO streams and 160 MHz wide channels used. This maximum value increases with Wi-Fi 6 to 6900 Mbit / s. Per antenna (MIMO stream) the rate increases from 802 to 1200 Mbit / s, i.e. over 1 GBit / s – which can be marketed effectively for advertising.
