What enhanced wireless standard supports the 6 GHz frequency band?

The enhanced wireless standard that supports the 6 GHz frequency band is Wi-Fi 6E.

Wi-Fi 6E extends the capabilities of Wi-Fi 6 (also known as 802.11ax) by introducing access to the new 6 GHz band. This additional spectrum provides more channels, reducing congestion and improving overall wireless performance, especially in environments with many devices. The 6 GHz band offers broader frequencies which leads to better speed, lower latency, and enhanced capacity for simultaneous connections.

In contrast, Wi-Fi 5 (802.11ac) only operates in the 5 GHz and 2.4 GHz bands, while Wi-Fi Protected Access and Wired Equivalent Privacy are security protocols rather than wireless standards. Hence, those options do not pertain to frequency band support. Wi-Fi 6E is specifically designed to leverage the benefits of this additional spectrum, making it the clear answer.
