Abstract (en)
[origin: WO2019120582A1] This invention relates to methods and systems for for localization. It is particularly concerned with localization techniques based on TDoA for wireless devices. Embodiments of the invention relate to techniques in which a transmitter transmits periodic distinguishable signals which are relayed upon receipt by the client whose location is sought in a form distinguishable from that of the transmitter. Signals from both the transmitter and the client are received by at least three signal receivers which generate a TDoA based on the difference taken for a signal to reach the receiver directly and via the client. Further embodiments of the invention provide a phase detector in the receivers to determine the TDoA between the signals.
