During an 18-month network modernization initiative, Three UK collaborated with Ericsson to enhance network energy efficiency by utilizing cutting-edge energy-efficient radios and employing AI and data analytics.

In late 2023, Three UK became one of the first major UK operators to adopt Ericsson's dual-band Radio 4490, known for its reduced power consumption and lighter weight, streamlining site access and accelerating site upgrades.

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.

In addition to deploying more energy-efficient radios, Three UK introduced software features that consume less power per radio during low-traffic periods. The new generation of radios leverages machine learning, passive cooling, and power-saving functionalities to autonomously manage 4G and 5G networks by deactivating radio components when idle and swiftly reactivating for service requests.

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.

The collaboration between Three UK and Ericsson has yielded up to a 70% improvement in network energy efficiency at selected sites. These enhancements have not only boosted network performance but also reduced site footprint and lowered CO2 emissions.
