Abstract
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 terminalstoby switching a channel in each beacon period and transmitting a beacon frame, a control device: measures communication conditions of the channel and interference wave influences; determines availability of the channel; and stores available channel information. The control devicedelivers the available channel information in the beacon frame to the terminal devicesto. The terminal devicesto: 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.
