Abstract :
The paper is concerned with the study of the co-channel cross-layer interference which appears in evolved mobile networks, in which femtocell access points (FAPs) have been deployed. We will investigate the levels of interference for the downlink communication channel, in two cases: macrocell base station (MacroBS) interference at the femtocell user (FUE), and FAP interference at the macrocell user (MUE). The simulations are carried out in a combined indoor-outdoor environment. The performances of the network are evaluated according to the signal to interference plus noise ratio, measured on the downlink communication channel. The results of the study reveal the impact of the deployment of femtocells in existing mobile networks.
