IEEE 802.11bf is an amendment to the IEEE 802.11 wireless LAN standard specifically designed to standardize WiFi sensing procedures, enabling interoperable and multi-vendor channel state information (CSI)-based sensing applications. It matters to the field because it provides a unified framework for wireless human sensing that moves beyond proprietary, device-specific implementations, facilitating widespread adoption and reproducibility across diverse hardware platforms. The amendment builds upon prior 802.11 physical layer variants such as 802.11ac, extending their sensing capabilities through formally defined sensing procedures applicable across varying channel bandwidths and deployment scenarios.
