Apparatus and method for measuring wireless range

An apparatus of a first electronic device in a wireless communication system, the first electronic device comprising:

• at least one transceiver;
• and
• at least one processor operatively coupled to the at least one transceiver;
• wherein the at least one processor is configured to:
• receive, from a second electronic device, a wireless signal,
• receive, from the second electronic device, a first sound signal,
• receive, from the second electronic device, a second sound signal, wherein the second sound signal is transmitted when a time period elapses after the first sound signal is transmitted, and
• determine a change amount of a distance between the first electronic device and the second electronic device based on a first distance and a second distance,
• wherein the first distance is determined based on a reception time of the wireless signal and a reception time of the first signal, and
• wherein the second distance is determined based on the reception time of the first signal, a reception time of the second signal, and the time period.
