Abstract
A wireless communication system is provided. A control device includes: a receiver configured to be able to receive information from radio frequency channels; a processor that judges whether a first channel is congested, and generates switchover instruction information when the first channel is judged to be congested; and a transmitter that transmits the switchover instruction information. Each node device includes: a receiver that receives information through the first channel; a transmitter that transmits information through a transmission channel; and a processor that recognizes whether a hop count from the control device is one, selects a second channel and specifies it as the transmission channel in a first case in which the receiver receives the switchover instruction information from the control device and the hop count is recognized as one, and specifies the first channel as the transmission channel in a second case in which the first case does not hold.
