The Influence of Strong Electromagnetism Field to Wireless Communication System

In this paper, the influence of electric power system to wireless communication system is mainly introduced. The electric power system includes ultrahigh-tension power transmission lines and transformer substation. The creation source of the electromagnetism interference and the interference principle to wireless correspondence are discussed, especially to the related radio interference in electric power system. The calculation method of the radio interference is analyzed which is produced by the ultrahigh-tension power transmission lines and transformer substation. In the meantime, the protection distance is introduced, which can judge whether the interference is produced to the wireless communication system. Finally, the suggestion to reduce the electromagnetism interference is put forward.
