According to prompting for the question, a more complete answer would be: The IEEE 802.11 PHY specification that includes support for operation in the 2.4 GHz, 5 GHz, and 6 GHz bands is IEEE 802.11ax. It is also known as Wi-Fi 6E. IEEE 802.11ax was released in 2021 and is the latest Wi-Fi standard. It offers a number of improvements over previous standards, including: Increased speed and capacity Improved performance in congested environments Reduced latency Support for new features such as MU-MIMO and OFDMA IEEE 802.11ax devices can operate in all three frequency bands, but the 6 GHz band is the most exciting new feature. The 6 GHz band offers more channels and less congestion than the 2.4 GHz and 5 GHz bands, which can lead to significant performance improvements. To take advantage of the 6 GHz band, you will need a Wi-Fi 6E router and Wi-Fi 6E client devices. Wi-Fi 6E devices are still relatively new, but they are becoming more and more common.
