A solution to dynamically decrease power consumption of wireless base stations and power them with Alternative energies

Abstract

Wireless network operators are facing the challenge of reducing their operating costs and carbon footprint, while extending operations to areas beyond electricity grids. In mature countries, reducing energy bill becomes a priority to support data growth despite flat revenues, and help finance strategic goals of innovation and differentiation. In emerging countries, alternative energy solutions are required to connect the next billion subscribers located in areas off the electricity grid without wasting all revenues in diesel generators running: diesel generator power can account for up to 35% of a Base Station site Total Cost of Ownership (TCO). The proposed paper describes how wireless equipment power consumption savings can be combined with efficient power management and by adding a mix of Alternative Energy sources to reduce the operating expenses of network operators, open wide opportunities to expand their network in off-grid regions and reduce their carbon footprint.
