发明名称 RADIO COMMUNICATION SYSTEM
摘要 <P>PROBLEM TO BE SOLVED: To provide a radio communication system in which the number of accommodated APs can be effectively utilized in each of communication areas when the plurality of communication areas are present. <P>SOLUTION: An Ethernet(R) signal is inputted from the outside of the areas E and F to an SW 70. The SW 70 distributingly outputs the acquired Ethernet(R) signal to any of APs 91a-91e according to network structure managed by the SW 70. Each of the APs 91a-91e converts the Ethernet(R) signal into a radio LAN signal in the form of an electric signal and outputs the signal to a master station 10. The master station 10 multiplexes frequencies of signals outputted from the APs 91a-91e, converts the result into an optical signal and outputs it to slave stations 20a and 20b. Each of the slave stations 20a and 20b transmits the signal transmitted from the master station 10 to a terminal in the form of a radio wave. <P>COPYRIGHT: (C)2005,JPO&NCIPI
