IEEE 802.11 has approved the creation of a new task group to work on a major amendment, IEEE 802.11bn, for next generation wireless LAN, that applies to carrier frequency operation between 1 GHz and 7.250 GHz.
This amendment defines modifications to both the IEEE Std 802.11 physical layer (PHY) and the IEEE Std 802.11 Medium Access Control (MAC). The amendment adds an Ultra High Reliability capability to a Wireless Local Area Network (WLAN). The Ultra High Reliability capability is defined for both an isolated Basic Service Set (BSS) and overlapping BSSs as:
· At least one mode of operation capable of increasing throughput by 25%, as measured at the MAC data service Access Point, in at least one Signal to Interference and Noise Ratio (SINR) level (Rate-vs Range), compared to the Extremely High Throughput MAC/PHY operation, and
· At least one mode of operation capable of reducing latency by 25% for the 95th percentile of the latency distribution compared to the Extremely High Throughput MAC/PHY operation and
· At least one mode of operation capable of reducing MAC Protocol Data Unit (MPDU) loss by 25% compared to the Extremely High Throughput MAC/PHY operation for a given scenario, especially for transitions between BSSs.
This amendment provides a mechanism to reduce power consumption for Access Points (APs) (including mobile APs) and improved Peer-to-Peer (P2P) operation compared to the Extremely High Throughput MAC/PHY operation.
This amendment shall ensure backward compatibility and coexistence with legacy IEEE 802.11 devices in the 2.4 GHz, 5 GHz, and 6 GHz unlicensed bands.

TGbn had scheduled 11 sessions during the November plenary. The group discussed around 60 technical submissions, covering a variety of topics, including but not limited to: spatial reuse, feedback, low latency, channel access, distributed RU, preemption, power save, non-primary channel access, coexistence, coordinated beamforming, sounding, security, enhanced long range, multi-AP, coordinated rTWT, L4S, coordinated TDMA, preamble and PPDU format, control, roaming, unequal modulation, QoS enhancements, etc.
The group approved over 110 motions that added additional concepts to the SFD such as 2xLDPC, ELR, (joint/sequential) CBF sounding, high priority EDCA, coexistence modes, more details for DRU, ELR, UEQM, C-TDMA, PS, NPCA, MAP, C-RTWT, AP PS, eMLSR, roaming, etc.
