TASK GROUP BF (WLAN SENSING)

Leadership

ChairTony Xiao Han (Huawei)Vice Chair Sang Kim (LG Electronics) Vice Chair Assaf Kasher (Self) Secretary Leif Wilhelmsson (Ericsson) Technical Editor Claudio Da Silva (Meta Platforms)

Background

802.11bf is a new Task Group about WLAN sensing within the IEEE 802.11 working group.

WLAN sensing is the use of PHY and MAC features of IEEE 802.11 stations to obtain measurements that may be useful to estimate features of objects in an area of interest.

  • Features = Range, velocity, angular, motion, etc.

  • Objects = Human, animal, etc.

  • Area of interest = Home, enterprise, vehicles, etc.

Goals (Derived from PAR)

Task Group bf is expected to develop an amendment that defines modifications to the IEEE 802.11 medium access control layer (MAC) and to the Directional Multi Gigabit (DMG) and enhanced DMG (EDMG) PHYs to enhance Wireless Local Area Network (WLAN) sensing (SENS) operation in license-exempt frequency bands between 1 GHz and 7.125 GHz and above 45 GHz.

This amendment enables:

  • Stations to inform other stations of their WLAN sensing capabilities

  • Request and setup transmissions that enable WLAN sensing measurements to be performed

  • Exchange of WLAN sensing feedback and information
