WI-FI TRACKING AND LOCALIZATION

passive target tracking via 5G wifi system

  • Existing passive target tracking methods require known receiver locations, which is difficult to satisfy in practice.

  • WiSLAT eliminates this requirement by achieving simultaneous localization and tracking via Doppler frequency shift measurements in a commercial WiFi system.

INDOOR POSITIONING OF UE VIA 5G WIFI SYSTEM

  • The emerging WiFi 7/8 Multi-Link Operation (MLO) presents an opportunity to achieve unprecedented robustness in RF sensing.

  • We demonstrate this by developing a tracking system that correlates Doppler frequency from multiple APs to cancel common errors and extract precise UE trajectory.
