Vodafone UK and Ericsson have successfully tried innovative artificial intelligence (AI) and machine learning (ML) solutions to enhance the energy efficiency of 5G networks. The trial, conducted at select sites across London, achieved up to a 33% reduction in daily power consumption of 5G Radio Units. These advancements mark a critical step toward reducing the environmental impact of mobile networks while maintaining seamless connectivity for users.

The trial utilised Ericsson’s Service Continuity AI App suite with Intelligent Energy Efficiency, which dynamically adjusts energy usage in the radio access network (RAN) based on live traffic data. By leveraging real-time insights, the system optimises power consumption without compromising performance. This approach not only supports sustainability goals but also lowers operational costs for network operators through reduced energy expenditure.

Three key features were tested during the trial: 5G Deep Sleep, 4G Cell Sleep Mode Orchestration, and the Radio Power Efficiency Heatmap. These tools collectively enable the network to intelligently manage energy use. For example, 5G Deep Sleep allows radios to enter an ultra-low power state during periods of minimal activity, while the Radio Power Efficiency Heatmap uses ML to pinpoint inefficiencies for targeted improvements. Together, these innovations pave the way for smarter, greener telecommunications infrastructure.

Andrea Donà, Chief Network Officer & Network Director, Vodafone UK, stated that “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. 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”.

Katherine Ainley, CEO, Ericsson UK and Ireland, likewise, mentioned that “It’s exciting to see how our work with Vodafone UK is making a real difference. Our ability to significantly reduce network energy consumption while maintaining high performance standards is a testament to the innovation and expertise of our combined teams. I’m really proud of what we’ve achieved here, it’s an important milestone in our ongoing journey to make networks smarter and more sustainable.”
