Patent ID: 8442446

Claim:
A radio communication device comprising: a first radio communicating unit configured to receive data according to a first radio communication type using one of a plurality of first radio channels provided in a first frequency band and configured to change the first radio channel to be used with a first period; a data processing unit configured to perform processing using data received by the first radio communicating unit; a first communication status determining unit configured to determine, for each first radio channel, whether a communication status of the radio channel is good; a ratio changing unit configured to change a ratio of setting, as the first radio channel to be used in the first radio communication type, a good channel whose communication status is determined as good by the first communication status determining unit, and a ratio of setting a not-good channel whose communication status is determined as not-good, according to a data receiving status of the first radio communicating unit and a processing status of the processing in the data processing unit; a setting unit configured to set, according to the ratios changed by the ratio changing unit, either the good channel or the not-good channel as the first radio channel to be used for radio communication according to the first radio communication type; a receiving speed calculating unit configured to calculate a data receiving speed of the first radio communicating unit; and a processing speed calculating unit configured to calculate a processing speed of processing by the data processing unit, wherein the ratio changing unit is configured to increase or decrease the ratio of setting the good channel and the ratio of setting the not-good channel as the first radio channel, according to the data receiving speed calculated by the receiving speed calculating unit and the processing speed calculated by the processing speed calculating unit.
