A radio communication apparatus includes a communication selecting unit for switching a plurality of communication units from one to another, a storage unit to hold spatial positions of a plurality of fixed stations for the communication means or semi-fixed stations for which position information can be acquired, and a characteristic of a radio wave used by the communication unit; an interference source prediction unit for monitoring a position of an interference source that will interfere with the communication unit, and predicting the position, a moving direction, and a characteristic of the interference source; and an interference determination unit for determining whether or not interference will occur as the spatial position and the characteristic of the radio wave held by the storage unit overlap with the position and the characteristic of the interference source predicted by the interference source prediction unit.
