    IEEE 802.11be Extremely High Throughput (EHT) is the potential next amendment of the 802.11 IEEE standard,[9] which will likely be designated Wi-Fi 7.[10][11] 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.[12] Speeds are expected to reach a theoretical maximum of 30Gbps.[13]

    Development of the 802.11be amendment is ongoing, with a goal of an initial draft by March 2021, and a final version expected by early 2024.[11]

    Candidate features

    The main candidate features mentioned in the 802.11be Project Authorization Request (PAR) are:[14]

    Additional features

    Apart from the features mentioned in the PAR, there are newly introduced features:[19]

    1. ^ a b c d e f g This is obsolete, and support for this might be subject to removal in a future revision of the standard
  • ^ For Japanese regulation.
  • ^ a b IEEE 802.11y-2008 extended operation of 802.11a to the licensed 3.7 GHz band. Increased power limits allow a range up to 5,000 m. As of 2009, it is only being licensed in the United States by the FCC.
  • ^ a b c d e f g h i Based on short guard interval; standard guard interval is ~10% slower. Rates vary widely based on distance, obstructions, and interference.
  • ^ a b c d e f g h For single-user cases only, based on default guard interval which is 0.8 microseconds. Since multi-user via OFDMA has become available for 802.11ax, these may decrease. Also, these theoretical values depend on the link distance, whether the link is line-of-sight or not, interferences and the multi-path components in the environment.
  • ^ a b The default guard interval is 0.8 microseconds. However, 802.11ax extended the maximum available guard interval to 3.2 microseconds, in order to support Outdoor communications, where the maximum possible propagation delay is larger compared to Indoor environments.
  • ^ Wake-up Radio (WUR) Operation.
  • ^ a b For Chinese regulation.
