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 user distribution is analysed together with the influence of environmental attenuation coefficient and allowed power difference in emission power between two signals, which are paired. It is pointed out that decreasing user density from the base

It is further presented to what extent the total loss in the system with the implementation of VAMOS technology is greater than the loss in the classic Erlang traffic model with the same traffic characteristics.
