WIRELESS COMMUNICATION SYSTEM, AND INTERFERENCE PREVENTING METHOD

摘要

To prevent communication interference between two or more wireless communication networks having mutually different physical layers. In a case where two or more wireless communication networks having mutually different physical layers coexist, and wireless communication is performed between a plurality of devices and a coordinator in each one of the wireless communication networks, the coordinator 3a of one wireless communication network 10a generates coexistence notification frame data used for notifying coordinators 3b of other wireless communication networks 10b of existence of the coordinator, encodes the generated coexistence notification frame data and inserts source data before the encoding into the encoded data as source code data so as to be set as FEC data, modulates the FEC data through a Gaussian frequency shifting keying system (GFSK) so as to be set as a GFSK modulated wave signal, and transmits the GFSK modulated wave signal to the coordinators 3b of the other wireless communication networks 10b.
