Base station equipment for communication systems

The basic base station equipment for digital mobile communications systems consists of amplifiers (AMP) to amplify the transmission and reception signals to desired levels, modems (MDE) to convert base band signals to high-frequency signals, speech processors (SPE) to convert voice signals to digital code strings, base station control equipment (BCE) that allocates radio channels and switches over channels with adjacent base stations, and the base station antennas (ANT).
