Wireless communication system communicable among a base unit and a plurality of handsets

DETAILED DESCRIPTION In view of the foregoing, it is an object of the present invention to provide a wireless communication system in which exchanges of control signals between the base unit and plurality of handsets can be completed more quickly.
To achieve the above and other objects, there is provided a wireless communication system capable of communicating by a frequency hopping method, which includes a main communicating device and a plurality of sub communicating devices in which the a main communicating device can be connected to an external communications path, and includes a hop frequency data generator that sequentially generates predetermined hop frequency data, a communication unit that uses the predetermined hop frequency data supplied from the hop frequency data generator to create transmission signals by frequency spreading input signals input from the main communicating device and to create output signals available in the main communicating device by frequency despreading reception signals, and a signal generator that generates predetermined control signals at predetermined timings and sends out through the communicating unit.
The sub communicating device can communicate wirelessly with the main communicating device, and includes as in the main communicating device a hop frequency data generator that sequentially generates the predetermined hop frequency data generated by the hop frequency data generator of the main communicating device, a communication unit that uses the predetermined hop frequency data supplied from the hop frequency data generator of an associated sub communicating device to create transmission signals by frequency spreading input signals input from the associated sub communicating device and to create output signals available in the associated sub communicating device by frequency despreading reception signals received from the main communicating device.
The sub communicating device further includes a signal generator that generates another predetermined control signals and sends to the main communicating device through the associated communicating unit after expiration of a predetermined period of time specific to each of the plurality of sub communicating devices from receipt of the control signals from the main communicating device
