Abstract

With the usages of femtocells, users can achieve better coverage and QoS in home or office environment. But with this cheap solution in two-tier WCDMA systems the interference is increasing in the adjacent network. Because of interference the number of femtocells per macrocell is limited. This article analyse the downlink interference types in two-tier WCDMA network and sets up a simulation model for these femtocell generated downlink interferences. The simulation deals with the house/office wall penetration loss which is limiting the interference. The aim of this article to find out how many femtocells can be deployed to a macrocell, and which parameters vary this limit.
