They wanted to reduce the energy consumption of mobile networks by half. Instead, they developed a framework that cut nearly three quarters of energy consumption.

Led by Alcatel-Lucent and Ericsson over the course of two and a half years, the EARTH (Energy Aware Radio and neTwork tecHnologies) consortium of 15 telecommunications providers, vendors and academic institutions developed everything from more efficient components in radio base stations to solutions on the radio network level, according to a press release from Alcatel-Lucent. The research was partially funded by the European Union’s Seventh Framework Program (FP7).

In the process, the consortium demonstrated how operators could save up to 70 percent of energy consumed in their networks using a holistic energy efficiency approach for 4G radio communications.
