PROBLEM TO BE SOLVED: To provide a communication device for use in a radio network that can determine a channel to be changed in a relatively short time when interference occurs, and also suppress increase in types of channels to be used while avoiding interference.SOLUTION: A communication device 10 has a first radio communication unit 11, a second radio communication unit 12, a channel selection unit 13 and a channel management unit 14. The first radio communication unit 11 has a function of communicating with a master station 20, and a function of transmitting a packet containing information of a channel determined by the channel selection unit 13 at a predetermined time interval. The second radio communication unit 12 communicates with equipment 40. The channel management unit 14 extracts, from the packet received by the first radiation communication unit 11, a channel which another communication device uses to communicate with the equipment 40, and stores the extracted channel. The channel selection unit 13 determines the priority order of the channel selection by using the information of the channels stored by the channel management unit, and determines a channel to be used in the second radio communication unit 12 by selecting the channels according to the priority order.SELECTED DRAWING: Figure 1 |
