A wireless communication system that includes a hub and multiple nodes is provided. The nodes include a wireless communication control unit that acquires, during a predetermined communication time period, a signal transmitted to the hub by a node; an RSSI calculating unit that calculates propagation information from the signal acquired by the wireless communication control unit; and an RSSI table creating unit that transmits the calculated propagation information to the hub. The hub includes a wireless communication control unit that receives propagation information transmitted by each of the nodes and an RSSI table aggregating unit that aggregates the received propagation information.
