Abstract:
A radio communication system for performing communication using frequency hopping, comprising:a radio control unit, anda plurality of radio communication units each radio communication unit being controlled wirelessly by said radio control unit;said radio control unit including:first storage means for storing a predetermined hopping pattern; andtransmitting means for transmitting wirelessly information, which is for generating another hopping pattern from the predetermined hopping pattern, to a radio communication unit; andeach said radio communication unit including:second storage means for storing the predetermined hopping pattern;receiving means for receiving said information transmitted wirelessly by said transmitting means; andcommunication means for generating another hopping pattern by causing the predetermined hopping pattern to be shifted, based upon said information received by said receiving means, and for communicating with another said radio communication unit by using the other hopping pattern in a case where communication is performed within a area controlled wirelessly by said radio control unit,wherein said transmitting means transmits information, which differs for every hopping pattern to be used in a case where a plurality of hopping patterns are used within the area controlled by said radio control unit.
