HetNets Powered by Renewable Energy Sources: Sustainable Next-Generation Cellular Networks

Renewable energy could be the key for sustainable next-generation cellular networks. The authors´ approach would let mobile operators feed base stations in a heterogeneous network using renewable energy sources. The authors compare their method to a classical grid-powered solution. They evaluate costs and CO₂ emissions savings for different scenarios to demonstrate that properly powering a heterogeneous network with renewable energy can be a sustainable and economically convenient solution.
