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

A wireless communication system that communicates using a frequency hopping method, comprising:

• a main communicating device that can be connected to an external communications path, said main communicating device including a hop frequency data generator that sequentially generates predetermined hop frequency data, a communication unit that uses the predetermined hop frequency data supplied from said hop frequency data generator to create transmission signals by frequency spreading input signals input from said main communicating device and to create output signals available in said main communicating device by frequency despreading reception signals, and a signal generator that generates predetermined control signals at predetermined timings and sends out through said communicating unit;
• and
• a plurality of sub communicating devices that can communicate wirelessly with said main communicating device, each of said plurality of sub communicating devices including a hop frequency data generator that sequentially generates the predetermined hop frequency data generated by said hop frequency data generator of said main communicating device, a communication unit that uses the predetermined hop frequency data supplied from said hop frequency data generator of an associated sub communicating device to create transmission signals by frequency spreading input signals input from said associated sub communicating device and to create output signals available in said associated sub communicating device by frequency despreading reception signals received from said main communicating device, and a signal generator that generates another predetermined control signals and sends to said main communicating device through said communicating unit of said associated sub communicating device after expiration of a predetermined period of time specific to each of said plurality of sub communicating devices from receipt of the control signals from said main communicating device.
