summary

P2PLocate localizes a single-antenna device by co-locating a batteryless on-body backscatter tag and using the tag to create intentional multipath plus user movement to infer direction and range, achieving median accuracy 0.88 m for static and mobile targets. It separates backscatter CSI, estimates motion parameters, and fuses Doppler-derived radial speed to resolve direction. Prototype uses Google Nexus 6P, Intel 5300, Raspberry Pi B4 and a custom tag with ADG902 & STEP-MAX10, tested across lab, meeting room, hallway, and corridor.
