Abstract: An electronic device according to an embodiment includes an mmWave communication module and a processor. The processor is configured to receive a first signal transmitted by a first external electronic device, identify a distance of a transmission path of the first signal, transmit a second signal, receive a third signal obtained when the second signal is reflected, identify a distance of a transmission path of the second signal based on a difference between a transmission time of the second signal and a reception time of the third signal, and determine whether the transmission path of the first signal is a line of sight (LoS) path between the electronic device and the first external electronic device based on a difference between the distance of the transmission path of the first signal and the distance of the transmission path of the second signal. In addition, other embodiments are possible.
