发明名称 Wireless communication device, wireless communication system and wireless communication method
摘要 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.

主权项 1. A wireless communication device that is configured to conduct wireless communication in both of a first wireless communication configuration and a second wireless communication configuration that differs from the first wireless communication configuration in communication characteristics, the wireless communication device comprising: a memory storing a software component; at least one processor configured to execute the software component in order to perform: switching, when the first wireless communication configuration is being used by the wireless communication device, the first wireless communication configuration to the second wireless communication configuration and switching, when the second wireless communication configuration is being used by the wireless communication device, the second wireless communication configuration to the first wireless communication configuration; forming an ad hoc wireless communication network together with different wireless communication devices; determining, at least when forming the ad hoc wireless communication network, whether or not there is a wireless communication device that becomes unable to conduct wireless communication due to changing the first wireless communication configuration to the second wireless communication configuration, from among the wireless communication device itself and the different wireless communication devices; controlling, when there is no wireless communication device that becomes unable to conduct wireless communication and it is necessary to change the first wireless communication configuration, to switch from the first wireless communication configuration to the second wireless communication configuration; and controlling, when there is a wireless communication device that becomes unable to conduct wireless communication, to leave in use the one of the first and second wireless communication configuration being used.
