WiFi CSI Human Sensing

Wi-Fi Channel State Information (CSI) sensing for human activity recognition—including gesture detection, occupancy monitoring, and multi-person tracking—is the central problem, addressed through signal processing and machine learning applied to CSI measurements from commodity Wi-Fi hardware. Work spans dataset collection, end-to-end sensing frameworks, and the IEEE 802.11bf standardization effort aimed at formalizing Wi-Fi sensing capabilities. A recurring concern is improving generalizability across domains and environments while reducing computational overhead through lightweight learning approaches.
