IEEE 802.11bn, dubbed Ultra High Reliability (UHR), is to be the next IEEE 802.11 standard.[4] It is also designated Wi-Fi 8. As its name suggests, 802.11bn aims to improve the reliability of Wi-Fi.[3] It is projected to be finalized in 2028.[5]


Notes

  1. ^ 802.11ac only specifies operation in the 5 GHz band. Operation in the 2.4 GHz band is specified by 802.11n.
  2. ^ Wi-Fi 6E is the industry name that identifies Wi-Fi devices that operate in 6 GHz. Wi-Fi 6E offers the features and capabilities of Wi-Fi 6 extended into the 6 GHz band.
  3. ^ The Wi-Fi Alliance began certifying Wi-Fi 7 devices in 2024, but as of January 2025 the IEEE standard 802.11be is yet to be ratified.
