The wireless ad-hoc communication system includes first and second networks each including one or more communication terminals; and one or more synchronizing terminals. The synchronizing terminals are capable of transmitting/receiving the beacons to/from the communication terminals. In the wireless ad-hoc communication system, at least one of the communication terminals belonging to the first network and at least one of the communication terminals belonging to the second network exist within a reachable range of the beacons from one of the one or more synchronizing terminals to construct one synchronized network with the first network, the second network, and the synchronizing terminals.
