PROBLEM TO BE SOLVED: To provide a communication system which always allow for communication in a good channel, with a limited energy, while enhancing the reliability of communication without requiring a complicated conventional procedure such as carrier sense.SOLUTION: In one transmission operation, a transmitter 10 transmits the same transmission data in more than one channels sequentially in given order at prescribed intervals, receives information indicating the transmission channel priority from a receiver 20 and stores the information, notifies the receiver of the current transmission channel priority, and performs time division multiplexing transmission of the same data and reception of the information indicating the transmission channel priority from the receiver 20 at prescribed intervals, while switching the priority of transmitting channels, based on the initial setting priority or the transmission channel priority received from the receiver 20.SELECTED DRAWING: Figure 1 |
