Abstract
A communications system that includes a transmission data generator configured to generate frequency band information indicating which frequency band is to be used for transmission of data information between said communication apparatuses; a transmitter configured to transmit the frequency band information by using a specific frequency band, set from among a plurality of frequency band assigned to the communications system, to transmit data information using at least one frequency band set from among said plurality of frequency bands; a receiver configured to receive the frequency band information, using the specific frequency band. The frequency band set as said at least one frequency band set from among said plurality of frequency bands, other than the specific frequency band, is made variable, at the time of establishing the wireless channel, the frequency band usable by the communications apparatus is restricted.
