PROBLEM TO BE SOLVED: To realize method and system for a radio exchange where not only frequency hopping is freely realized but also its sureness is enhanced so as to reduce communication impossibility and, moreover, the problem in privacy and noise is eliminated. SOLUTION: A radio communication equipment at a transmission side decides (S2205, S2206) a succeeding frequency channel to which frequency hopping is executed from the present frequency channel at the time of starting communication, transmits (S2207, S2208) the information of the succeeding frequency channel which is decided by the present frequency channel and, then, the frequency channel is changed-over (S2209) into the decided succeeding frequency channel. The radio communication equipment at a reception side receives information by the present frequency channel, recognizes frequency channel information and changes-over the frequency channel into the recognized one. Data is transmitted from the radio communication equipment at the transmission side to the one at the reception side by the decided succeeding frequency channel. |
