Performance analysis of femtocell network in macrocell environment

Femtocells (HeNB) are deployed within macrocell coverage area to increase performance of indoor user. In order to cover, all indoor users, HeNBs make a network, known as femtocell network. Since, HeNBs use same spectrum, they are causing interference on both MeNB users (MUE) and among HeNB users (HUE). The performance of the femtocell network depends on the SINR of HUEs of respective HeNBs, which eventually depends on the interference produced on it. In order to improve the performance, we need to minimize the interferences among themselves. In this paper, we first study the SINR performance of HUEs in the macrocell environment. We also analyze the outage probability in femtocell network. Finally, we consider the power consumption issue of femtocell network.
