The equation of duplex radio cellular system
The paper deals with the equation of a duplex cellular radio communication system, which includes all key parameters of transmit equipment of a base station and mobile station. The solution of the equation is possible with respect to any parameter of transmission equipment. The conditions of the balanced radio communication in the descending and ascending channels of cells are defined. The need of use of the antenna low-noise amplifier on a base station at essential losses in the combine operator or an antenna feeder is discussed.
