5G energy efficiencies: green is the new black (the sequel)

This follow-up report to 5G energy efficiencies: green is the new black establishes the context and rationale for improving energy efficiency among operators and their supply chain. This comes as 5G enters a new phase, with 5G adoption reaching more than 15% from almost nothing three years ago. From an energy perspective, the new stage is about cost efficiencies, network performance, densification, energy security, and contributing to carbon emission reduction efforts.

The report reviews the multiple lines of technical innovation underway, including leveraging efficiencies associated with passive infrastructure, cooling solutions and the use of AI to maximise equipment sleep states. Energy efficiency is now a core objective – just as security and performance are. This report provides an understanding of the factors helping or hindering that goal, and the outlook for the next five years on a technological and competitive level.
