Wi-Fi 6 is a transmission standard for WLAN networks that was published in 2020 by the Institute of Electrical and Electronics Engineers (IEEE) and the Wi-Fi Alliance. Here, high transmission rates in the gigabit range are possible on up to eight channels. It is more stable and faster than its predecessor.
Wi-Fi 6 follows the 802.11ac (Wi-Fi 5) standard and can provide up to four times the data throughput. It is considered to be particularly energy-efficient and suitable for real-time applications. Wi-Fi 6 is also known as High Efficiency WLAN (HEW) or IEEE 802.11ax.
The standards were renamed in 2018 to simplify the notation: 802.11n became Wi-Fi 4, 802.11ac became Wi-Fi 5, and 802.11ax became Wi-Fi 6.
Speed with Wi-Fi 6
Wi-Fi 6 offers speeds of up to 4800 Mbit / s. However, this speed is only possible in theory; in practice, it also depends heavily on other factors, such as the bandwidth used and the number of connections.
More devices with Wi-Fi 6
Significantly more end devices can connect via Wi-Fi 6. This is so important because the number is constantly increasing. Whereas in the past only the cell phone and the computer were connected, today there are often many more in the smart home . Televisions, tablets, vacuum robots, heating, smart lamps, intelligent loudspeakers and much more are added here.
With MU-MIMO (Multiple Users, Multiple Input, Multiple Output), the router can communicate with up to eight devices at the same time instead of processing the requests one after the other. In addition, the flow of information is improved by OFDMA (Orthogonal Frequency Division Multiple Access). This creates a significantly improved data throughput.
Back to the tried and tested: WiFi 6 frequency bands
While the previous standard only used the 5 GHz frequency band, Wi-Fi 6 also works again in the 2.5 GHz range. As with its predecessor, Wi-Fi 6 also works with up to 160 MHz channels. Under the same conditions, Wi-Fi 6 theoretically has 37 percent more bandwidth than Wi-Fi 5. In practice, however, the difference is significantly smaller. Nevertheless, the latency is noticeably reduced.
In order to avoid interference, however, Wi-Fi 6 only uses channels 1, 6 and 11 in the 2.4 GHz range. In the 5 GHz range, significantly more channels are available.
In addition, the expansion to Wi-Fi 6E took place in 2021, which means that the 6 GHz frequency band can now also be used. So there is even more space.
Clutter-free Wi-Fi 6
The more routers there are, the more there are overlaps in radio traffic. With the spatial reuse function, a router can now use time control to identify which data concerns it. Several routers can use one channel without interference.
The overcrowded channels are also dealt with with the BSS Coloring function. This means that end devices determine whether communication is taking place on the same channel in their own network or in a third-party network. With the latter, end devices can now try to send data instead of having to wait as before.
Wi-Fi 6 is compatible with all predecessors. This is particularly useful because it usually takes some time for all end devices to come out with the new technology.
Environmentally friendly Wi-Fi 6
With the Target Wake Time (TWT) feature, end devices can be put into sleep mode, thus saving energy. This is entirely in line with environmental protection and green IT
