In Russia BSs are radiotransmitting radiotechnical objects that radiate electromagnetic power in UHF band (300-3000 MHz). Besides each BS is supplied with a set of radiotransmitting equipment of radiorelay communication working in SHF band (3-30 GHz) that is responsible for BS integration in the net as a whole. The radiating power of BS transmitters as a rule does not exceed 5-10 W per channel. BS antennas are usually set at the height of 15-100 meters from the ground on already existing constructions: public, official, industrial and residential buildings, chimneys of industrial enterprises etc., or on the specially built towers.
