PROBLEM TO BE SOLVED: To provide a synchronism establishing method applicable to high speed radio communication between an optical radio relay and a plurality of optical radio terminals. SOLUTION: In the optical radio communication method where data signals are transmitted by time sharing while performing synchronization control when data is transmitted/received between an optical radio relay 3 and one of a plurality of optical radio terminals 1, 2 within communicable range of the optical radio relay 3, the synchronization control synchronizes transmission frequency of the optical radio relay 3 with transmission frequency of each optical radio terminal 1, 2 by delivering a sync signal at a constant interval from the optical radio relay 3. High speed data transmission/reception is effected using a high frequency data signal and reflected light from the optical radio relay 3 can be removed using a low frequency sync signal. |
