More Information
Summary:A method and system for phase shift based time of arrival (TOA) reporting in passive location ranging is herein provided. According to one embodiment, a method includes measuring, by a receiver station (RSTA), a first phase shift time of arrival (PS-TOA); measuring, by an initiator station (ISTA), a second PS-TOA; reporting, by the RSTA, the first PS-TOA, reporting, by the ISTA, the second PS-TOA; broadcasting, by the RSTA, time stamps; and determining, by a passive station (PSTA), a differential distance between the PSTA and a pair of the RSTA and ISTA based on the first PS-TOA, the second PS-TOA, and the broadcast time stamps.
