Provided is, a wireless network that conducts wireless communications having superior latency and power-saving performance, while avoiding interference wave influences by using multiple channels. Besides conducting communications with wireless communication terminals 102 to 104 by switching a channel in each beacon period and transmitting a beacon frame, a control device 101: measures communication conditions of the channel and interference wave influences; determines availability of the channel; and stores available channel information. The control device 101 delivers the available channel information in the beacon frame to the terminal devices 102 to 104. The terminal devices 102 to 104: select an optimum channel by switching the channel in each beacon period depending on the available channel information in the received beacon frame and on transmission conditions of the channel used by oneself; and conduct the wireless communications. With this, it is possible to switch usage channels rapidly while avoiding interference wave influences.
