PROBLEM TO BE SOLVED: To provide a wireless communication system capable of preventing degradation of communication conditions due to a variation of reception power without reducing workability of radio reception checking operation.SOLUTION: When an operation input reception section 6 of a master unit TR1 receives an input operation to start a radio checking operation, the operation input reception section 6 outputs an operation signal to start the radio checking operation to a control section 1. A control section 1 of a slave unit TRj compares the reception strength of the radio signal including a radio checking message transmitted from the master unit TR1 to a threshold value, and notifies a notification section 5 of the comparison result. As a result, degradation of the communication conditions due to a variation of the reception power can be reduced without reducing the workability of the checking operation of received radio. |
