Faster Wi-Fi is here but what does it mean to you...Wi-Fi 6E?

What is Wi-Fi 6E

One variation of the 802.11ax standard is Wi-Fi 6E. It utilizes spectrum at frequencies of 2.4 GHz, 5 GHz, and, for the first time ever in Wi-Fi history, 6 GHz. Wi-Fi 6E, the most recent Wi-Fi generation, adds a number of new capabilities that enhance individual cells' and WLAN networks' overall capacity while also enabling faster speeds and lower latency. Additionally, Wi-Fi 6E needs to be properly designed and configured in order to completely reap its benefits, just like with earlier 802.11 variations.

How Does Wi-Fi 6E Work

Wi-Fi 6E's operating foundation is built on the IEEE 802.11 framework.

Wi-Fi 6E is a half-duplex technology that, like earlier Wi-Fi standards, is constrained by the laws of physics for interference and coexistence with signals in the same unlicensed spectrum.

discrete channel utilization also impose restrictions on it.

All three bands—2.4 GHz, 5 GHz, and 6 GHz—benefit from 6E's additional characteristics, but the 6 GHz band alone boasts the most striking features. With the addition of 6E's 1,200 MHz of additional frequencies to this spectrum, it is possible to create up to 59 new 20 MHz wide channels or seven new 160 MHz wide channels, with equally spectacular numbers for 40 MHz and 80 MHz wide channels.

Wider channels result in higher throughput, whereas more available channels result in less competition.

The following features are part of Wi-Fi 6E's technical details:

  • highest-performing modulation scheme ever used in Wi-Fi -- namely, 1024 quadrature amplitude modulation;

  • potential for up to 8x8 up-link/down-link, though most 6E access points (APs) top out at 4x4;

  • orthogonal frequency-division multiple access, which breaks up channels into new combinations called resource units with varying widths to service different types of client devices simultaneously; and

  • target wake time and basic service set coloring, which enable battery power savings for client devices and the ability to more efficiently coexist with other APs that may be using the same channel.

The fact that no legacy clients are permitted in the Wi-Fi 6E 6 GHz frequency is perhaps what makes it so amazing.

The highest-performance users were frequently sacrificed in favor of backward compatibility for client devices in all other 802.11 standards. The Wi-Fi 6E aspect of it comes to an end here.
