Abstract: An electronic device includes an ultra wide band (UWB) circuit and at least one processor operatively coupled to the UWB circuit. The at least one processor is configured to receive a response signal from at least one external electronic device via the UWB circuit; identify information on distance between the at least one external electronic device and the electronic device; identify an external electronic device located within reference distance from the electronic device in the at least one external electronic device; transmit a second UWB signal via the UWB circuit, toward the identified external electronic device; receive a reflected signal of the second UWB signal caused by an external object including the identified external electronic device within time interval identified based on distance between the electronic device and the identified external electronic device; and based on the reflected signal, obtain information on the external object. Other various embodiments are possible.
