1. A wireless communication system in which wireless stations are configured to perform transmission, and a plurality of wireless modules are configured to operate in a shared frequency band and are installed in the wireless stations,
wherein each of the wireless stations is configured to notify a control device of environment information that includes capacity information regarding the wireless station and information regarding a surrounding wireless environment, and to set frequency channels in the plurality of wireless modules, the wireless stations being notified of the frequency channels by the control device, and
the control device is configured to calculate a frequency channel of each wireless module of the each wireless station based on the environment information collected from the each wireless station, following a control guideline that is determined in advance, and notify the wireless stations of the frequency channels, wherein calculating the frequency channel of the each wireless module of the each wireless station comprises:
selecting, from the wireless stations that are connected to the control device, a wireless station of which throughput is degraded most, and
reselecting a frequency channel that increases throughput for a wireless module that has the smallest throughput out of a plurality of wireless modules that are installed in the wireless station.
