A Simulation Framework for LTE-A Systems With Femtocell Overlays

Free registration required

Executive Summary

The use of femtocells is an efficient way to improve coverage and quality of service while on the other side the deployment cost for the service provider is kept in extremely low level. Long Term Evolution Advanced (LTE-A) systems with femtocell overlays aim to provide better indoor voice and data coverage and to increase network capacity. One of the major technical challenges that femtocell networks are facing nowadays, is the cross-tier interference, i.e., the interference between the femto base stations and the macro-cell infrastructure. To this direction, the authors have designed and implemented a framework that simulates femtocell overlays integrated over LTE-A macrocellular systems.
