PROBLEM TO BE SOLVED: To provide an optical space transmission system in which a communication available area is avoided after the fact in the case of building up a wireless network. SOLUTION: This system is provided with a base station 10 that builds up a network by using an optical carrier with respect to a single or a plurality of optical radio transmitter-receiver sets A1-A3 in existence in a coverage area of its own system, and with a wireless controller 20 that sends a coverage control signal denoting the necessity of transmission of an optical carrier through an optical radio communication means to the base station 10. The base station 10 controls a liquid crystal display switch on the occasion of receiving the coverage control signal from the wireless controller 20 to dynamically change a forwarding direction of the optical carrier in the coverage direction. |
