IEEE 802.11bn
Wireless networking standard in development / From Wikipedia, the free encyclopedia
Not to be confused with IEEE 802.11b.
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]

Close
802.bn will require more advanced antennas for channels above 6 GHz 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.
- Multiple access point (AP) coordination and transmission
- Millimeter wave (mmWave) frequencies
- Low latency
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 optical fiber.
