ITU and ETSI agree method to assess energy efficiency of mobile networks
New standard applicable to live radio access networks
Geneva, 17 March 2015 – ITU and the European Telecommunications Standards Institute (ETSI) have agreed a new standard to measure the energy efficiency of mobile radio access networks (RANs), the wireless networks that connect end-user equipment to the core network.

The standard is the first to define energy-efficiency metrics and measurement methods for live RANs, providing a common reference to evaluate their performance. Its application will build uniformity in the methodologies employed by such evaluations, in parallel establishing a common basis for the interpretation of the results.

“Improving the energy efficiency of ICT has become central to all fields of technical standardization at ITU,” said ITU Secretary-General Houlin Zhao. “We are moving towards a world that will host billions of connected devices, things and objects, making energy efficiency essential to the functionality and environmental sustainability of ICT networks.”…
