Abstract
In this paper we developed the method for determination of output power of base station as the function of distribution of users’ density in one GSM cell. The method consists of several steps: determination of the function of density distribution (PDF) and function of distribution (CDF) of distance between user and base station, finding PDF of output power of one GSM channel. In order to prove calculated results, we developed the program for simulating seizure and release channels in one GSM cell. It is necessary that inverse function of CDF of distance between user and base station exists in order to implement this program. This simulation program can be used to estimate CDF of total emission power of base station. Calculation of CDF of total emission power is, except in simplest cases, pretty complicate.

Summary
One of the main guidelines in the design of all telecommunication systems, including the systems in mobile network, is power saving, [1]−[7]. In this paper we present how to calculate the mean value of total BTS output power in the case of non−uniform users’ density. In order to investigate the dependence of output power on the users’ density, let us suppose that that output power of one channel depends only on distance MS–BTS It means that output power of the channel, when connection is established on it, is random variable, which can be expressed in the function of d as w v(d) a d ,. The emission power of BTS is random variable designated by wB and its PDF is fwB(x), CDF is FwB(x) and mean value is wBm. It is necessary to use one channel for each connection.
