In a wireless microphone system, a master device includes a master device control unit that generates a communication table in which a pair of a carrier wave and a slot which are used for communication with m microphone slave devices are set for one frame period, based on a total number of six carrier waves in a DECT system and n slots constituting one frame period of the DECT system, and k wireless processing units that perform communication using the DECT system with corresponding individual microphone slave devices among m microphone slave devices, based on the generated communication table. The k wireless processing units respectively operate synchronously based on the same clock signal.

Communication apparatus, wireless microphone system and communication method

In a wireless communication system, transmitters that transmit data, receivers that receive data, and repeaters that relay data communicate with one another in a wireless manner. The transmitter wirelessly communicates with the receiver by using first slave-device identification information for performing communication as a slave device of the receiver. The receiver wirelessly communicates with the transmitter by using first master-device identification information for performing communication as a master device of the transmitter, and wirelessly communicates with the repeater by using second slave-device identification information for performing communication as a slave device of the repeater. The repeater wirelessly communicates with the receiver by using second master-device identification information for performing communication as a master device of the receiver.
