PROBLEM TO BE SOLVED: To attain high speed data communication by using lots of channels. SOLUTION: A communication equipment M is provided with radio communication sections MSR1 -MSRn and a communication equipment S is provided with radio communication sections SSR1 -SSRn . Let transmission frequencies of transmission sections MS1 -MSn be fS1 -fSn , let reception frequencies of reception sections SR1 -SRn be fR1 -fRn , let reception frequencies of reception sections SR1 -SRn be fS1 -fSn , and let transmission frequencies of transmission sections SS1 -SSn be fR1 -fRn , then transmission reception frequencies fS1 , fR1 are allocated for a control channel Cs and transmission reception frequencies fS2 , fR2 -fRn are allocated for data communication channels DS2 -DSn , and the control channel Cs is utilized to exchange communication channel information or the like served by itself with a destination communication equipment so as to utilize simultaneously the data communication channels DS2 -DSn for data communication. |
