Abstract:
A wireless communication system using a GPS time signal from a satellite comprising:a plurality of communication networks including a first network operable under a first communication protocol and capable of transmitting a GPS-synchronization signal in synchronism with the GPS time signal, and a second network operable under a second communication protocol different from the first communication protocol; and a communication device operable to communicate with the first network and the second network under the first communication protocol and the second communication protocol, respectively, and including a receiving part which receives the GPS-synchronization signal from the first network, a transmitting part which transmits an output signal to the second network, and a controlling part which synchronizes a time of transmission of the output signal from the transmitting part to the GPS-synchronization signal, wherein the second network is constructed to correct a synchronization of operation time thereof based on the output signal received from the communication device.
