Abstract:
A wireless communication device includes two wireless communication units, each switching one of a VHF band and a UHF band to another to conduct wireless communication; a determination unit which determines whether or not it is necessary to change a frequency band when one of the wireless communication units uses the VHF band to conduct the wireless communication, and further determines whether or not there is a wireless communication device that becomes unable to conduct wireless communication due to using the UHF band when the change is necessary; and a communication control unit which performs control to switch the band to the UHF band when it is determined that there is no wireless communication device which becomes unable to conduct wireless communication, and to leave the band as the VHF band when it is determined that there is a wireless communication device which becomes unable to conduct wireless communication.
