A wireless communication device is disclosed in which signal quality values C[t] of a wireless signal received by the wireless communication device is successively measured at variable time intervals &Dgr;t, mean value μ of the successively-measured signal quality values C[t] is calculated, standard deviation &sgr; of the successively-measured signal quality values C[t] is calculated, a determination is made as to whether the signal quality value C[t] at present time satisfies a predetermined inequality which represents that a signal quality value C[t] at arbitrary time lies within k times the standard deviations &sgr; away from the mean value μ, and lengths of the time intervals &Dgr;t for the measurement device are controlled based on the determination. |
