Three UK has improved its network energy efficiency by up to 70 per cent at selected sites as a result of its partnership with Ericsson.
Three has achieved this saving through the deployment of Ericsson’s next-generation AI-powered hardware and software solutions, at the same time as improving its network performance, reducing site footprint and lowering CO2 emissions.
As part of an ongoing network modernisation initiative over the last 18 months, Three has worked with Ericsson on improving network energy performance through a combination of energy efficient radios and the use of AI and data analytics.
Late in 2023, Three became one of the first major operators in the UK to deploy Ericsson’s dual-band Radio 4490, which consumes less power and is 25 per cent lighter than previous models, simplifying site access and speeding up site upgrades.
Combined with the deployment of more energy efficient radios, Three has also implemented a series of software features that consume less power per radio during low traffic hours. By using advanced machine learning, passive cooling and power-saving features, the new generation of radio works autonomously across 4G and 5G networks to switch off radio components when not active, while having the capability to switch on again in microseconds for the next service request.
Iain Milligan, chief network officer, Three UK, said, “Three UK’’s collaboration with Ericsson marks a milestone in our commitment to sustainability. We’ve achieved excellent improvements in energy efficiency while expanding network capabilities for our customers. We plan to take these learnings on board for future projects, ensuring that we continue to improve the environmental impact of our network.”
Evangelia Tzifa, chief technology officer, networks and managed services, Ericsson UK and Ireland, said, “Together with Three UK, we are redefining the network of the future and making it both smarter and more energy efficient.
“To increase network availability and performance while reducing network energy consumption is a testament to the technology and expertise of our two great teams. I am both excited and proud to know that we are building a modern digital infrastructure together that brings not only superior performance for Three customers, but also helps to make the future more promising and sustainable.”
