A frequency-hopping radio communication system is disclosed comprising a control unit which transmits to and receives from each of a plurality of slave stations using a frequency-hopping mode of operation. During a start-up mode, the control unit communicates a starting message to each slave station using a predefined frequency. The message identifies to each slave station a frequency-hopping sequence to be used to select the frequencies from a group of frequencies for transmission to and reception from the control unit. This message also specifies to each slave station unique starting frequencies in the frequency-hopping sequence at which to begin transmitting and receiving. All slave station transmissions are synchronized to the control unit transmissions, thereby preventing any two stations from concurrently using the same frequencies for either transmitting to or receiving from the control unit.
A radio communication system including a control unit which transmits information to and receives information from each of a plurality of stations using frequencies selected from a group of frequencies using a frequency-hopping sequence, said system comprising
A control unit for use in a radio communication system including means for transmitting information to and receiving information from each of a plurality of stations using frequencies selected from a first group of frequencies using a frequency-hopping sequence, said control unit further comprising
A station for use in a radio communication system including means for receiving information from and transmitting information to a control unit using frequencies selected from a group of frequencies using a frequency-hopping sequence, said station further comprising
