A broadcast wave retransmission system is provided at a low cost, in an extended radio base station system (10) having a master base station (20) for mobile communications and an extended radio base station (40) that is connected to the master base station (20) via a communication line (9) and that has a radio transmitting/receiving function for the mobile communications, by receiving a broadcast wave, superposing a broadcast signal obtained from the received broadcast wave onto a mobile communication signal sent from the master base station (10) to the extended radio base station (40), transmitting the resultant signal to the extended radio base station (40), and separating the broadcast signal from the superposed and transmitted signal and retransmitting the resultant signal as a broadcast wave in the extended radio base station (40). In this way, broadcast and mobile communication signals can be received in hard-to-reach areas such as underground malls without having to provide separate extender equipment for each. |
