IEEE 802.11be Extremely High Throughput (EHT) is the potential next amendment of the 802.11 IEEE standard.,[1] and will likely be designated as Wi-Fi 7.[2][3] 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.[4]

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.[3]

Candidate features[edit]

The main candidate features mentioned in the 802.11be Project Authorization Request (PAR) are:[5]

  • 320 MHz bandwidth and more efficient utilization of non-contiguous spectrum,
  • Multi-band/multi-channel aggregation and operation,
  • 16 spatial streams and Multiple Input Multiple Output (MIMO) protocols enhancements,
  • Multi-Access Point (AP) Coordination (e.g. coordinated and joint transmission),
  • Enhanced link adaptation and retransmission protocol (e.g. Hybrid Automatic Repeat Request (HARQ)),
  • If needed, adaptation to regulatory rules specific to 6 GHz spectrum,
  • Integrating Time-Sensitive Networking (TSN) IEEE 802.1Q extensions for low-latency real-time traffic: [6][7]
    • IEEE 802.1AS timing and synchronisation
    • IEEE 802.11aa MAC Enhancements for Robust Audio Video Streaming (Stream Reservation Protocol over IEEE 802.11)
    • IEEE 802.11ak Enhancements for Transit Links Within Bridged Networks (802.11 links in 802.1Q networks)
    • Bounded latency: credit-based (IEEE 802.1Qav) and cyclic/time-aware traffic shaping (IEEE 802.1Qch/Qbv), asynchronous traffic scheduling (IEEE 802.1Qcr-2020)
    • IEEE 802.11ax Scheduled Operation extensions for reduced jitter/latency

Additional features[edit]

Apart from the features mentioned in the PAR, there are newly introduced features:[8]

  • Newly introduced 4096-QAM (4K-QAM),
  • Contiguous and non-contiguous 320/160+160 MHz and 240/160+80 MHz bandwidth,
  • Frame formats with improved forward-compatibility,
  • Enhanced resource allocation in OFDMA,
  • Optimized channel sounding that requires less airtime,
  • Implicit channel sounding,
  • More flexible preamble puncturing scheme,
  • Support of direct links, managed by an access point.
