RADIO FREQUENCY HOPPING COMMUNICATION METHOD AND RADIO COMMUNICATION SYSTEM

摘要

PROBLEM TO BE SOLVED: To always ensure a high communication efficiency while precluding the possibility of use of a same frequency at the same time by plural base stations. SOLUTION: An identical frequency hopping pattern is used for each of base stations 21-24. Furthermore, a frequency changeover timing of each of the base stations 21-24 is synchronized. Moreover, each cycle of the frequency hopping pattern is deviated among the base stations 21-24 so that plural base stations 21-24 do not use one frequency at the same time.
