Abstract

In telecommunications, femtocell technology has been introduced to improve indoor coverage and capacity. Femtocell is a small, low-power cellular base station deployed to offer better good services with low cost as it reduces the transmitted power. It is also designed to offload the traffic in macrocell to the femtocell network. However, the unplanned deployment of femtocells and their uncoordinated operations may result severe interference conditions among the femtocells and between macrocells and femtocells. In this paper, power control techniques has been proposed at the base stations to mitigate interference and increase the network capacity. Power control equation is applied at the base stations for both outdoor macrocell users and indoor femtocell users, and a framework is developed by using the MATLAB software to analyze the signal performance. From the results obtained, this proposed technique has increased number of successful handover and hence, can effectively eliminates co-channel interferences between macrocells and and femtocells in urban and busy area.
