PROBLEM TO BE SOLVED: To provide an interference prediction system 1 and the like that efficiently identifies a booster 70i about which it is predicted that it will suffer interference due to IM distortion in advance when part of the band of a radio signal for television broadcasting is shifted to use in a mobile communication system such as a mobile phone, and can achieve highly economical countermeasures before the shift.SOLUTION: At the installation position of a booster 70, the reception level Rof a downlink reference signal included in a downlink radio signal of an existing cellular base station 10 is measured. An interference level prediction value Ithat can be input into the booster 70 is obtained by adding a correction valueΔL of the amount of radio wave propagation attenuation of the downlink reference signal from the cellular base station 10 to a communication module 40 after shift based on the reception level Rand parameter information acquired by a parameter information acquisition unit 53, a transmission power maximum setting value Pafter the shift, and an antenna directivity gain correction value C, and subtracting a transmission power value Rof the downlink reference signal.
