PROBLEM TO BE SOLVED: To provide a radio audio transmission method that performs both transmission of an audio signal by radio and communication by another radio device, and that has increased resistance to radio wave noise.SOLUTION: A transmitter and a receiver select one channel from a channel group; the transmitter detects that the channel has become idle, then waits for a waiting time T1 shorter than the shortest packet interval defined by other radio communication procedures, and then transmits an audio packet; the receiver waits for a waiting time T2 shorter than the shortest packet interval after completion of receiving the audio packet, and then returns a response signal. After completion of transmitting and receiving a prescribed transmission packet number of audio packets according to this procedure, the transmitter and receiver switch the communication channel and repeat the above processing. If an error rate of any of the channels has exceeded a prescribed value, the transmitter and receiver switch the channel group and move to a channel on which there are few errors. |
