Abstract
An estimator 120 of a mobile station 100a of the present invention estimates traveling speed information which is a value variable with either a traveling speed of the mobile station or a variation in the traveling speed. A comparison unit 130 or a comparison unit 320 compares the traveling speed information estimated by the estimator with a threshold defined as a value of traveling speed information for achieving a desired level of communication quality which varies depending on the traveling speed. A selector 150 or a selector 340 selects an applicable frequency band in response to a result of comparison.
