<p>A method of preventing interference of adjacent frequencies which selects and uses a carrier frequency which is not adjacent to another carrier frequency is disclosed. A cellular system A is composed of a plurality of base stations and a mobile station, and a cellular system B is composed of a plurality of other base stations and another mobile station. For cellular system A, a carrier frequency adjacent to a carrier frequency used in cellular system B and a carrier frequency not adjacent thereto are determined. If a received power of a perch channel sent by a base station of cellular system B is larger than a threshold value, the mobile station uses the carrier frequency which is not adjacent to carrier frequency used in cellular system B. <IMAGE></p> |
