Abstract
A wireless communication system includes a plurality of base stations that can switch to either first or second communication method and that communicates wirelessly with terminals by the switched communication method and a control apparatus that manages the plurality of base stations. The control apparatus includes: an acquisition unit that acquires, from each base station, throughput of the base station and RSSI of each terminal that communicates wirelessly with the base station; and a switch instruction unit that instructs to each base station switch the current communication method when there is, among the plurality of base stations, a base station in which throughput has decreased within fixed interval, and instructs to re-switch to the communication method before switching to base stations in which throughput before and after switching of communication method is same but a specific standard, based on RSSI after switching of communication method, is not satisfied.
