Since the communication method uses optical wireless communication in which straightness is high but high-speed communication is possible, a path for communication while avoiding an obstacle via a relay is calculated. In the communication method, the relay is guided and moved to an appropriate place according to the calculated path, and a signal is transmitted and received by using optical wireless communication using the relay that has moved to an appropriate place.
