IEEE P802.11be™/D1.5, March 2022
(amendment to IEEE 802.11-2020 standards
as amended by IEEE P802.11ax™-2021,
IEEE P802.11ay™-2021,
IEEE P802.11az™/D4.0,
IEEE P802.11ba™-2021,
IEEE P802.11bb™/D0.7,
IEEE P802.11bc™/D2.0,
IEEE P802.11bd™/D2.1)
and IEEE P802.11-REVme™/D1.1)

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 Gbps, 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
