1. A wireless communication device configured to communicate with another wireless communication device, the wireless communication device comprising:
an information wireless communicator that is configured to transmit first control information to the other wireless communication device by a first wireless communication method, the first wireless communication method being a wireless LAN communication method;
a sound signal transmitter that is configured to transmit a first sound signal to the other wireless communication device by a second wireless communication method different from the first wireless communication method, the second wireless communication method being a wireless microphone communication method; and
a selection controller that is configured to select at least one of a first transmission processing of transmitting the first control information from the information wireless communicator to the other wireless communication device by the first wireless communication method and a second transmission processing of embedding the first control information in the first sound signal and transmitting the first control information from the sound signal transmitter to the other wireless communication device by the second wireless communication method,
wherein the selection controller is configured to select the second transmission processing and to switch a processing from the first transmission processing to the second transmission processing when a wireless communication intensity of the first wireless communication method is equal to or smaller than a threshold.
