<p><P>PROBLEM TO BE SOLVED: To prevent communication interferences between wireless communication networks where frequency hopping is performed. <P>SOLUTION: A wireless communication network 10a switches a communication frequency between a device and a coordinator every time zone by a frequency hopping method to perform radio communication, and sends an EB composed with a switched communication frequency every time zone. A wireless communication network 10b sets, before a first communication period immediately after power-on, a scanning period for scanning the EB sent from the wireless communication network 10a, and, if the EB received in the scanning period matches its own communication frequency, acquires it and exerts control for preventing communication interferences. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
