OPTICAL RADIO COMMUNICATION SYSTEM AND OPTICAL RADIO COMMUNICATION METHOD

摘要

PROBLEM TO BE SOLVED: To provide an optical radio communication system and an optical radio communication method which enable one optical radio master station and a plurality of optical radio slave stations perform intercommunication.SOLUTION: The optical radio communication system comprises optical radio slave stations and an optical radio master station. The optical radio slave station comprises: a slave station optical reception unit which receives downlink signal light; a slave station optical transmission unit which transmits uplink signal light; and a slave station communication control unit which controls one-to-N communication. The optical radio master station comprises: a master station optical transmission unit which transmits downlink signal light to the optical radio slave station; a transmission direction control unit which controls a transmission direction of the downlink signal light from the master station optical transmission unit; a reception direction control unit which controls a reception direction of the uplink signal light from the optical radio slave station; a master station optical reception unit which receives the uplink signal light from the reception direction control unit; and a master station communication control unit which controls one-to-N communication with the plurality of optical radio slave stations.
