PROBLEM TO BE SOLVED: To effectively utilize a radio resource by synchronizing radio blocks among pluralities of PHS base station devices thereby avoiding interference. SOLUTION: This system consists of a master PHS base station device 1, that generates a synchronizing signal and sends a control channel and two slave PHS base station devices 2, 3 that receive the synchronizing signal and are operated in accordance with the instruction of the master PHS base station device 1, and the master PHS base station device 1 collectively manages communication channels. The master PHS base station device 1 is connected to two sets of the slave PHS base station devices 2, 3 via a synchronizing signal transmission interface SYNC and a data communication interface DATA. |
