1. A method, performed by an electronic device, of determining a location of an external device, the method comprising:
receiving a trigger signal, which is output at a first location;
receiving, after the trigger signal is received, a first chirp signal transmitted from a first external device among at least one external device present at a different location from a location of the electronic device, the first chirp signal being transmitted according to the trigger signal being received by the first external device;
obtaining, based on a time point at which the first chirp signal is received, a difference value between a time point at which the trigger signal is received by the electronic device and a time point at which the trigger signal is received by the first external device; and
determining a location of the first external device based on the difference value.
