Abstract
In this paper, we present a simulation model for the Universal Mobile Telecommunication Systems (UMTS). For validation purposes, we have developed a much more detailed simulation of the system written in C language. The results of a previous mathematical model showed that, the product form holds in the case of two cells, and the objective of this paper is to prove the same result using simulation, and to show that the behavior of the system is similar to that in the previous work done in the mathematical model. Once the product form of Jackson's Theorem is Shown to hold, then it is possible to go to a more advanced stage to analyze the 3G network, and to get the performance measures, which will help in making decisions at the design stage
