Provided is a wireless communication control system including a first radio having a directional antenna, a second radio, a directivity control unit controlling the directivity of the directional antenna of the first radio, and a directivity information storage unit storing directivity information relating to a directivity, the directivity information being applied to the directional antenna of the first radio in relation to wireless communication between the first radio and the second radio in accordance with a plurality of change patterns indicating a temporal change in a received signal intensity. The directivity control unit acquires a temporal change in a received signal intensity during wireless communication between the first radio and the second radio, selects, from among pieces of the directivity information stored in the directivity information storage unit, directivity information corresponding to the change pattern corresponding to the temporal change in the received signal intensity, applies the selected directivity information, and executes wireless communication between the first radio and the second radio. Accordingly, the influence of fading between radios is suppressed as much as possible and wireless communication between radios is suitably performed.
