Intelligent Energy Managed Service for Green Base Stations

Energy consumption and CO2 emissions have recently become topics of particular interest across the cellular telecommunication industry. This situation is moving this industry towards the introduction of renewable sources of energy, such as solar energy, wind energy, etc. for the energy supply to their networks. These solutions are environmentally friendly and technically proven, but when it comes to real implementation there are several drawbacks that limit their applicability (e. g. instable sources of energy, number and size of energy system infrastructure elements, as solar panels). To cope with these constraints, in this paper, a method / system, jointly with some results of early implementations, is described for adapting the service (i.e. coverage and/or capacity) provided by a base station, as a function of the weather forecast (regarding the renewable energy source), the stored energy in the back-up battery supply, and historical base station power consumption data, over a time period.
