In order to protect and develop digital mobile communnication, it is necessary to measure radio noise in the urban environment.The paper discusses the measuremet of effective antenna noise temperature, a characteristic parameter of radio noise power. A system has been developed for the measurement. According to the difference of radio noise power, this system makes two kind
