IEEE P802.11be/D3.0, January 2023

Draft Standard for Information technology— Telecommunications
and information exchange between systems Local and metropolitan area networks—
Specific requirements

Part 11: Wireless LAN Medium Access Control (MAC) and Physical Layer (PHY) Specifications

Amendment 8: Enhancements for extremely high throughput (EHT)

Prepared by the 802.11 Working Group of the
LAN/MAN Standards Committee of the IEEE Computer Society

Abstract: This amendment defines standardized modifications to both the IEEE Std 802.11 physical layers (PHY) and the Medium Access Control Layer (MAC) that enable at least one mode of operation capable of supporting a maximum throughput of at least 30 Gbit/s, as measured at the MAC data service access point (SAP), with carrier frequency operation between 1 and 7.250 GHz while ensuring backward compatibility and coexistence with legacy IEEE Std 802.11 compliant devices operating in the 2.4 GHz, 5 GHz, and 6 GHz bands. This amendment defines at least one mode of operation capable of improved worst case latency and jitter.
Keywords: EHT, extremely high throughput, jitter, latency, MAC, medium access control, PHY,physical layer, wireless local area network, WLAN
