WIRELESS COMMUNICATION SYSTEM

摘要

PROBLEM TO BE SOLVED: To reduce interference in a communication system using the same frequency band when transmitting a wireless signal from a master device to a slave device.

SOLUTION: In a wireless communication system 10 comprising a master device 100 and a slave device 200 connected electronically with the master device 100 via wireless communication, the master device 100 comprises: registration means for registering the slave device 200 in a memory 111 of the master device 100; transmission means 190 for transmitting a wireless signal to the slave device 200 registered in the memory 111; and a slave device state determination part 113 for determining whether the slave device 200 is in a state connected physically to the master device 100. When there is only one slave device 200 registered in the memory 111, and the slave state determination part 113 determines that the slave device 200 is physically connected to the master device 100, the transmission means 190 reduces transmission electric power of the wireless signal to be transmitted to the slave device 200.
