EPSRC/VCE Strategic Partnership: Green Radio

Department Name: Institute of Advanced Telecommunications

Abstract

There is a need on environmental grounds to reduce the energy requirements of radio access networks. From an operator perspective, reduced energy consumption translates directly to the bottom line - lower Operating Expenditure (OPEX). These are the key drivers of the Green Radio programme. Both wide area public networks (traditionally cellular ) and local area private networks (traditionally wireless LAN ) will be considered, recognizing that the structure of a Green Radio Network may differ from today's radio networks. Thus in essence, the specific objective of the Green Radio programme is to investigate and create innovative methods for the reduction of the total power needed to operate a radio access network and to identify appropriate radio architectures which enable such power reduction.

Description That small cells and cell densification in radio access networks helps to save energy consumption while growing capacity. That the salient energy and capacity metrics in radio access networks is area averaged power, area averaged throughput and their product. That energy efficiency should be evaluated in terms of both energy savings and capacity gains separately and not as one bit/joule metric.
Exploitation Route Findings can be used to design future radio access networks such as LTE-Advanced (4G). Findings directly support and initiate research into 5G radio access networks.

Title VCE System Level Simulator (VCEsim) 
Description As part of the Green Radio project, a system level simulator for modelling the performance of multi-user, multi-cell LTE radio access networks was developed. The software was used to evaluate the energy efficiency of techniques developed by researchers across Bristol, Edinburgh, KCL and Sheffield to established an integrated energy solution. The software was made available in open source form to the member companies of MVCE and the partner Universities.
