ABSTRACT:
A wireless communication system having wireless terminal stations to perform direct communication without passing through a wireless base station. This system includes a wireless communication device which performs either a first wireless communication using a first channel having a first frequency band or the second wireless communication using a second channel having a second frequency band with a bandwidth greater than that of the first frequency band. This system also includes a generation device which generates a switching control frame to control switching between a communication period by the first wireless communication and a communication period by the second wireless communication, and a communication control device which controls the wireless communication device so as to transmit the switching control frame. A wireless terminal station is selected as a temporal central control station having a switching control right to control switching between the first and second wireless communications.
