<P>PROBLEM TO BE SOLVED: To prevent communication interference among two or more radio communication networks having mutually different physical layers. <P>SOLUTION: When two or more radio communication networks 10 having mutually different physical layers coexist and the respective radio communication networks 10 perform radio communication between a plurality of devices and coordinators, the coordinator 3a in one radio communication network 10a generates coexistence notice frame data for notifying the coordinator 3b of another radio communication network 10b of its own presence, encodes the generated coexistence notice frame data, inserts the original data before the encoding as source code data to the encoded data to achieve FEC data, modulates the FEC data by a Gaussian frequency shift keying system (GFSK) to achieve GFSK modulation wave signals, and transmits the GFSK modulation wave signals to the coordinator 3b in another radio communication network 10b. <P>COPYRIGHT: (C)2011,JPO&INPIT |
