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.”
Luis Jorge Romero, ETSI Director General: “ETSI has a track record of
developing market-driven standards and specifications to deliver improved energy
efficiency in telecommunications networks and equipment. We are particularly
pleased by the result of this cooperation which has produced ITU-T L.1330 and
the technically equivalent ETSI ES 203 228.”
The new standard, Recommendation ITU-T L.1330 “Energy efficiency measurement
and metrics for telecommunication network”, was developed by ITU-T Study Group 5
in cooperation with the ETSI Technical Committee on Environmental Engineering
and in liaison with the 3rd Generation Partnership Project (3GPP) and the GSM
Association (GSMA).
ITU-T L.1330 accounts for the fact that optimizing the energy efficiency of
equipment within a network does not guarantee the optimization of its overall
energy efficiency. The standard takes a more comprehensive view of a RAN,
incorporating impacts on energy efficiency caused by the interactions of
interconnected equipment within complex networks.
The scope of the standard extends to radio base stations, backhauling
systems, radio controllers and other infrastructure radio-site equipment. The
technologies covered are GSM, UMTS and LTE (including LTE-Advanced).
ITU-T L.1330 offers a pragmatic measurement approach that focuses on the
performance of ‘partial’ networks to extrapolate estimates of the energy
efficiency of ‘total’ networks. It provides for a total network to be defined by
topologic, geographic or demographic boundaries, enabling estimations of the
energy efficiency of an operator’s network, a country or continent’s networks,
or networks distinguished by their coverage of urban or rural areas. The result
of these estimations is captured by an ‘assessment report’, the form of which is
detailed by the standard.
