O2 pumps green appeal of 5G

While 2020 might not be the catalyst year for 5G some were hoping for, O2 has turned to the environmental benefits of the technology to engage enterprise customers.

ITU, ETSI set standard to measure RAN energy efficiency

The United Nation’s ICT body the International Telecommunications Union (ITU) and the European Telecommunications Standards Institute (ETSI) have agreed a standard to measure the energy efficiency of radio access networks (RANs). The ITU said this is the first such standard and claimed it will unify energy efficiency evaluations of live RANs and the interpretation of results of such assessments.

Prioritising efficiencies: energy versus spectrum

Efforts to improve energy efficiency in cellular have focussed mostly on the electrical efficiency of modules such as the power amplifiers or the cooling. But the higher level network design has largely escaped attention until recently. Simon Tonks, expert in Communications and Electronic Systems at PA Consulting Group, investigates.
