Abstract: A method includes determining, for each time interval in a series of time intervals, (i) whether at least one wireless signal measurement was received in the time interval, each wireless signal measurement associated with a pair of anchors, and (ii) whether at least one step was detected in the time interval. The method also includes selecting a state of a tracking filter state machine based on whether the at least one wireless signal measurement was received in the time interval and whether the at least one step was detected in the time interval. The method further includes determining a location of an object using the tracking filter state machine based on the selected state.

Abstract: According to certain embodiments, an electronic device comprises: a wireless communication module configured to support ultra-wide band (UWB) communication; and at least one processor operatively connected with the wireless communication module, wherein the at least one processor is configured to: set the wireless communication module to a wake-up state; when a given number of first ranging response messages (RRMs) are received from second external electronic devices after receiving a first ranging initiation message (RIM) from a first external electronic device in a RIM slot of a first ranging round, set the wireless communication module to a sleep state after receiving a first ranging final message (RFM) from the first external electronic device in a RFM slot of the first ranging round until a RIM slot of a second ranging round is reached after the first ranging round; set the wireless communication module to the wake-up state in the RIM slot in the second ranging round; and set the wireless communication module to the sleep state if a second RIM is not received from a third external electronic device in the RIM slot in the second ranging round.
