A frequency determination apparatus (30) acquires a past dataset in which given frequency-specific time-series data indicating frequency-specific communication status of a wireless base station (10) based on a signal-to-noise ratio (SNR) over a predetermined monitoring period in time series is associated with frequency-specific evaluation value data indicating an evaluation value evaluating the communication status during a subsequent period following the monitoring period by frequency. The frequency determination apparatus (30) generates an evaluation value inference machine learning model. The frequency determination apparatus (30) inputs the frequency-specific time-series data with a given preceding period as the monitoring period to the evaluation value inference machine learning model to acquire an output of the frequency-specific evaluation value data with a future period following the relevant preceding period as the subsequent period, and determines a frequency to be used for the wireless communication based on the acquired frequency-specific evaluation value data.
