IEEE 802.11bf: Toward Ubiquitous Wi-Fi Sensing

Understand

Wi-Fi is among the most successful wireless technologies ever invented.

• As Wi-Fi becomes more and more present in public and private spaces, it becomes natural to leverage its ubiquitousness to implement groundbreaking wireless sensing applications such as human presence detection, activity recognition, and object tracking, just to name a few.
• This paper reports ongoing efforts by the IEEE 802.11bf Task Group (TGbf), which is defining the appropriate modifications to existing Wi-Fi standards to enhance sensing capabilities through 802.11-compliant waveforms.
• We summarize objectives and timeline of TGbf, and discuss some of the most interesting proposed technical features discussed so far.
