Vodafone UK and Ericsson have partnered for a trial exploring how AI can improve network efficiency for the telco’s 5G network.

According to Vodafone, the tests have reduced daily power consumption of 5G radio units by up to 33 percent at some sites in London.

Ericsson provided its AI and ML-powered software for the trial. It says its Service Continuity AI App can be used by mobile carriers to manage network energy requirements, reduce operating expenditure, and cut carbon emissions.

The trial focused on three use cases: 5G Deep Sleep, 4G Cell Sleep Mode Orchestration, and a Radio Power Efficiency Heatmap. The features work together to measure, predict, and optimize energy consumption across the network.

This gives Vodafone the option to reduce power in certain components of its network during low-traffic periods and rapidly reactivate them when needed. Through the use of 5G Deep Sleep, Vodafone can cut energy consumption by 70 percent during low-traffic hours.

“By working with Ericsson to successfully apply these innovative software solutions to our network, we’re able to significantly improve energy efficiency without impacting the service our customers receive,” said Andrea Donà, chief network officer & network director, Vodafone UK.

“Reducing power consumption at our trial sites is a big win – both financially and environmentally – and shows we can continue to improve the efficiency of our network as we build 5G coverage across the UK.”
