Summary

The rapid development and commercialization of 5G radio communication technology is further accelerating 5G network construction. While it is an important enabler for the digitalization of other industries and thereby contributes to significant energy savings and emission reductions, it is also important to consider the energy consumption of the 5G network infrastructure itself.

Recommendation ITU-T L.1390 identifies energy saving potentials, describes energy saving principles and technologies for 5G RAN and related equipment, and provides best practice recommendations on when and how these technologies should be used and controlled, thereby reducing 5G RAN energy consumption, saving operational costs and making 5G RAN a green and high-efficiency network.
