PURPOSE:To attain efficient transmission of the same information by sending information simultaneously by radio from each base station of its own system after all decentralized base station equipments receive the information. CONSTITUTION:The radio communication system having the centralized control function is provided with a master base station 5, decentralized base stations 6, 7 installed at a location remote from the master base station 5 and plural mobile slave stations 2 and each base station equipment makes communication with the slave stations 2 by a constant output in the same operating frequency. The master base station equipment 5 is provided with a means for sending a star/end signal of carrier sense to all the decentralized base stations 6, 7 of its own system at a prescribed time difference simultaneously and a means for transferring the information to all the decentralized base stations 6, 7 of its own system only when the result of carrier sense to all the base stations is enabled for transmission. After all the decentralized base station equipments receive information, the information is sent in radio from each base station of its own system at the same time. Thus, the same information is sent efficiently. |
