Abstract
This invention is a system polarization base station antenna anti interference arrangement method that base stations do not communicate with each other but to the third station of a mobile, PHS wireless city call. In the anti interference field that a antenna's emission and another receive are co-frequency or adjacent frequency, the antennas that emit or receive signals are vertical polarization and horizontal polarization antennas. Stations that may interfere with each other emit different polarized wave, one is vertical polarization and the other is horizontal polarization, and the two waves can not interfere each other, so the interference problem is solved radically. Cell phones can receive horizontal and vertical polarization waves, and cell phones signal can also be received by horizontal and vertical polarization waves. So the utility factor of frequency resources is raised.
