Wireless technology continuouslyimprove and develop. The first devices using Wi-Fi 6 technology were certified in September 2019, and have not yet received widespread distribution. However, developers are already developing the next standard of Wi-Fi 7 wireless technology, which provides data rates that are unprecedented today.
According to the information that has appeared, the theoretical maximum speed of the new Wi-Fi 7 will be about 30 Gb / s, which is more than three times faster than the standard Wi-Fi 6, which is 9.6 Gb / s.
Meanwhile, the most used todayday, the Wi-Fi 5 (802.11 ac) protocol, in turn, is 40% slower than Wi-Fi 6 (802.11 ax) and at the same time requires much greater power consumption. Another significant advantage of Wi-Fi 6 will be the use of a more secure WPA3 protocol. Wi-Fi 6 also supports 1024 quadrature amplitude modulation (1024-QAM) technology and MU-MIMO technology, which allows you to transfer data over 8 streams and transmit data to more devices.
Future Wi-Fi 7 standard instead of technologyMU-MIMO CMU-MIMO technology will be introduced, working already on 16 streams. In addition, the signal modulation method will be updated to 4096-QAM and support will be introduced for three frequency ranges: 2.4 GHz, 5 GHz and 6 GHz, which will work simultaneously.
In early 2020, the Wi-Fi industry regulatorThe Alliance announced the extension of the standard specification to the Wi-Fi 6E version, for which operation with a frequency range of 6 Hz is available. The national regulator, the United States Federal Communications Commission (FCC), allowed the unlicensed use of the 6 GHz frequency band a few days ago. A similar decision must be made by the European regulator. The introduction of Wi-Fi 6E is scheduled for 2021, when the Wi-Fi Alliance will issue certificates for devices that support this standard.
