Green energy solution for femtocell power control in massive deployments

Mobile data traffic has skyrocketed in recent years and will continue to grow and demand more capacity. Continued heterogeneous networks' evolution and the utilization of massive Femtocell deployments will facilitate the meeting of capacity demands as expected towards 5G and telecom 2020-vision. The CO2 footprint of power usage is becoming spotlighted and energy-aware solutions are required. This paper reviews recent Femtocell downlink power control frameworks and proposes a novel comprehensive one taking into consideration issues like intra-interference (Femto-Femto), dense-deployments and environmental impact. Simulation results show up to 68% user throughput improvement and up to 20.69kg/year CO2-emission reduction for one Femtocell.
