<P>PROBLEM TO BE SOLVED: To provide a radio communication system which can reduces consumption power of a slave unit and is resistant to interference from other radio communication systems. <P>SOLUTION: A radio communication system 1 comprises a plurality of slave units 2 (A and B) each having a communication function between the slave units, and a master unit 3 having a communication function with the slave units. The master unit 3, when receiving interference from other radio communication systems, switches a communication channel used for the radio communication with the slave units 2. The slave unit 2(A), after the communication channel is switched, notifies of channel information indicating a current communication channel to be used for the radio communication with the master unit 3 using the prior communication channel having been used for the radio communication with the master unit 3 before the switching of the communication channel. When the slave unit 2(B) receives the channel information notified by the slave unit 2(A) as another slave unit using the prior communication channel, the communication channel used for the radio communication with the master unit 3 is updated. <P>COPYRIGHT: (C)2012,JPO&INPIT |
