Researchers at the University of Southern California, working with Samsung, have developed a model for a small cell that could be powered by solar or wind energy, eliminating the need for backup energy from "dirty" power plants. The theoretical model and the leader of the team that developed it, Harpreet Dhillon, were praised by Jeff Reed of Virginia Tech. "One of the chief obstacles of setting up modern communications in emerging countries is finding a steady source of power. He has shown theoretically the mechanism that allows renewable energy harvesting alone to power the network," Reed said.
