What is Wi Fi 6?
802.11ax means Wi-Fi 6, it will achieve higher modulation mode (1024-QAM), higher frequency width (160M frequency width), and a more complete MU-MIMO.
(Multiple users, more in and more out), making the theoretical bandwidth up to 9607.8M. The latest Wi-Fi 6 standard can work in both the 2.4G and 5G frequency bands, and can replace the previous WiFi4 and WiFi5 standards in the future.
