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: An electronic device is provided. The electronic device includes an ultra-wideband (UWB) communication circuit, a processor operatively connected to the UWB communication circuit, and a memory operatively connected to the processor. The memory stores instructions, and when the instructions are executed, the instructions, when executed, further cause the processor to establish a wireless communication channel with an external electronic device using the UWB communication circuit, perform positioning communication with the external electronic device based on a predetermined period, via the wireless communication channel, recognize a distance between the electronic device and the external electronic device, and a changing trend of the distance, based at least on the positioning communication, and change the positioning communication period based on the recognized distance and the changing trend.
