IEEE 802.11bn, dubbed Ultra High Reliability (UHR), is to be the next IEEE 802.11 standard.[9] It is also designated Wi-Fi 8. As its name suggests, 802.11bn aims to improve the reliability of Wi-Fi.[10]
802.bn will require more advanced antennas for channels above 6GHz which are used in 802.11be and lower. 42.5 GHz and 71 GHz require line of sight and cannot penetrate walls. Outdoors 802.bn will be attenuated by rain as is experienced by satellite communications. See rain fade.
The goal of 802.11bn is to reach 100 Gbps speeds. This is faster than copper Ethernet which tops out at 40 Gbps. This will require retrofitting ceiling mounted access points with single mode fiber.
