Description
IEEE 802.11 is the family of standards defining Wireless LAN PHY and MAC layers — the substrate of every CSI sensing paper in the bibliography. This umbrella entry canonicalises the bare aliases (WiFi, Wi-Fi, WLAN); the per-generation notes (ieee-802-11n, ieee-802-11ac, ieee-802-11ax, ieee-802-11bf) capture the CSI-relevant differences between generations.
Specs / capabilities
- 2.4 GHz, 5 GHz, 6 GHz, and 60 GHz bands across generations
- OFDM PHY since 802.11a/g; OFDMA + spatial reuse since 802.11ax
- Frame structure exposes Long Training Field (LTF) used for channel estimation → CSI
- MIMO since 802.11n; MU-MIMO since 802.11ac; OFDMA since 802.11ax
- 802.11bf (in standardisation) formalises Wi-Fi as a sensing modality
Tooling
- See per-generation notes for CSI extraction toolchains
