Claim Text:
1. A wireless communication system comprising: a master device including a first time measuring unit configured to count time, a first wireless transmitter-receiver unit configured to perform wireless communication by a frequency hopping system and configured to output a first change timing signal and configured to output a transmission timing signal at a time of wireless transmission, and a first control unit configured to output a first sync signal to the first time measuring unit, after the transmission timing signal is received and then a carrier frequency is changed a predetermined number of times according to the first change timing signal; and a slave device including a second time measuring unit configured to count time, a second wireless transmitter-receiver unit configured to perform wireless communication by a frequency hopping system and configured to output a second change timing signal and configured to output a reception timing signal at a time of wireless reception, and a second control unit configured to output a second sync signal to the second time measuring unit after the reception timing signal is received and then a carrier frequency is changed the predetermined number of times according to the second change timing signal, wherein the first change timing signal, the transmission timing signal, and the first sync signal are different from one another, and wherein the second change timing signal, the reception timing signal, and the second sync signal are different from one another.
