In this paper, we present the influence of user density distribution in the base station cell on the (un)pairing probability and on the loss caused by the lack of idle traffic resources in GSM systems, which use VAMOS technology. The influence of use

In this short paper we consider a cell in the network of mobile users. It is proved that the mean value of distance between a user and a base station and the mean value of emission power to a user are calculated in a different manner. These two value
