Due to the increasing demand for higher data rates by mobile users, the deployment of femtocells under macro coverage has been adopted by 3GPP LTE-Advanced systems as one of the main proposals to enhance the network performance in the respects of coverage and capacity improvement especially for indoor users. However the random deployment of femtocells raise the issue of interference between macrocell and femtocells and its impact on coverage and capacity of the network which becomes a critical challenge for LTE-Advanced system designers. In this paper we study and analyze the efficiency of different deployment locations of femtocells. Simulations show that by deploying femtocells at an appropriate location, the coverage almost doubled while the data rate received by the end user enhanced by 28% on average as compared to random deployment.
