Description
IEEE 802.11bf is the upcoming Wi-Fi sensing amendment that standardises the procedures for negotiating, scheduling, and reporting CSI-style channel measurements between Wi-Fi stations. From the thesis perspective, 802.11bf matters because it promises a vendor-neutral substitute for the patchwork of CSI extraction tools (Intel 5300, Atheros, Nexmon, ESP32) that dominates current research and constrains reproducibility. It is treated here as a method/protocol rather than a piece of hardware.
When it's used
- Forward-looking system-design discussions where a sensing infrastructure is assumed
- Standards-aware ISAC research
- Reproducibility framing — what 802.11bf can and cannot replace
Limitations
- Deployment is still nascent; few commodity APs implement the full procedure
- Reporting cadence and quantisation may be coarser than research-grade tools
- Vendor extensions risk fragmenting the standard
