<P>PROBLEM TO BE SOLVED: To provide a radio communication system which can appropriately set a frequency channel used for radio communication between a radio reader-writer device and a radio tag device. <P>SOLUTION: When radio communication is performed using different frequency channels between a plurality of different types of radio reader-writer devices 2 and a radio tag device 3 to offer different services, one of the radio reader-writer devices 2 receives a radio signal transmitted from the other radio reader-writer device 2, and transmits information contained in the radio signal such as frequency channel information (peripheral frequency channel information) and type information (peripheral type information) along with the radio signal which includes those pieces of information. The radio tag device 3 sets a frequency channel used in radio communication between the radio reader-writer device and itself on the basis of the frequency channel information, type information, peripheral frequency channel information and peripheral type information included in the radio signal from the radio reader-writer device 2. <P>COPYRIGHT: (C)2013,JPO&INPIT |
