However, their performance can be compromised by the cross-tier interference with existing macrocell infrastructure or between adjacent femtocells, especially in the case of co-channel deployment. One way to address this, is adjusting the transmit power of every femto base station with respect for overall performance. To this direction, we have implemented a framework that simulates femtocell overlays over LTE-Advanced (LTE-A) macrocellular systems. The framework allows power management over user-defined femtocell deployment, deciding their power levels according to three different power schemes. The resulting throughput is presented for every point of the macrocell in a user-friendly GUI. In this paper, we present the design of this framework and discuss the results.10aFemtocell10aPower Control1 aBouras, Christos1 aPapazois, Andreas1 aKokkinos, Vasileios1 aDiles, Georgios  uhttp://telematics.upatras.gr/telematics/publications/power-management-over-co-channel-femtocells-lte-systems
