IEEE 802.11be is the next amendment of the IEEE 802.11 standard,which will be designated Wi-Fi 7 It will build upon 802.11ax, focusing on WLAN indoor and outdoor operation with stationary and pedestrian speeds in the 2.4, 5, and 6 GHz frequency bands. Speeds are expected to reach a theoretical maximum of 30 Gbit/s.
