PROBLEM TO BE SOLVED: To provide a wireless communication system that can optimally conduct communication control in response to a state of communication traffic. SOLUTION: A master set counts number of idle communication slots not occupied by a slave set during communication at present, sets and transmits the information as to the counted idle slot number to a super-frame and shifts to a halt state where the transmission of the super-frame is stopped when the master set receives super-frames from other master sets in the same area and no slave set is in connection. |
