1. A band control method for controlling a frequency band which a first communication apparatus and a second communication apparatus use at data transmission, whereinfrequency bands which said first communication apparatus and said second communication apparatus use at data transmission are different frequency bands, the band control method comprising the steps of:

  • a bandwidth presumption step for presuming a first bandwidth required by said first communication apparatus at data transmission and a second bandwidth required by said second communication apparatus at data transmission;

    a bandwidth comparison step for comparing said first bandwidth with a first bandwidth used which said first communication apparatus currently uses and comparing said second bandwidth with a second bandwidth used which said second communication apparatus currently uses; and

    a bandwidth used determination step for adjusting said first bandwidth and said second bandwidth according to comparison results obtained by said bandwidth comparison step and for determining a third bandwidth used by said first communication apparatus at data transmission and a fourth bandwidth used by said second communication apparatus at data transmission.
