Abstract: A method and an electronic device for ranging are provided. An ultra-wideband (UWB) signal is received from an external device through a first antenna. A communication state between the external device and the electronic device is identified using information about communication quality included in the UWB signal. A signal received through a second antenna is identified by decoding the received signal based on the identified communication state. A distance between the electronic device and the external device is determined based on whether the received signal is a low frequency (LF) signal.

Abstract: A method includes receiving at least one wireless signal measurement and motion sensor measurements. The method also includes generating a location estimate based on the at least one wireless signal measurement. The method also includes determining whether a step is present based on the motion sensor measurements. The method also includes, in response to determining that a step is present, determining a step heading offset based on the location estimate and the motion sensor measurements, and determining a step length and heading based on the motion sensor measurements and the step heading offset. The method also includes determining a location of an object based on at least one of (i) the at least one wireless signal measurement or (ii) the step length and heading.
