Presence Tech Showdown: Wi‑Fi Sensing vs. UWB vs. Soli Radar – Who Will Own the Future?
Wi‑Fi Sensing (IEEE 802.11bf) repurposes 2.4 GHz, 5 GHz, and 6 GHz Wi‑Fi signals to detect movement across a typical home, offering tens of meters of range, millisecond‑level latency, and energy‑efficient operation by piggybacking on existing routers. Ultra‑Wideband (UWB; IEEE 802.15.4z) uses ultra‑wide pulses
