<p><P>PROBLEM TO BE SOLVED: To solve the problem of preventing communication interference between no less than two radio communication networks having mutually different physical layers. <P>SOLUTION: In order to prevent communication interference between radio communication networks 10a and 10b of mutually different communication standards, a coordinator 3a in each radio communication network 10 has a scanning period to scan a coexistence notification signal transmitted from a coordinator 3b in the other radio communication network 10b for a prescribed period before the first super frame after the power activation while transmitting its own coexistence notification signal in a format which is predetermined with the coexisting other radio communication network 10b. When the coexistence notification signal transmitted from the coordinator 3b in the other radio communication network 10b is obtained during the scanning period, control is made to prevent communication interference with the other radio communication network 10b. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
