The mobile industry through NGMN’s Green Future Networks Programme has come together to find solutions to increase network energy efficiency and enable operators to reduce their electricity consumption. In this publication we outline and prioritise the various options available to increase network energy efficiency. In particular energy saving approaches are organised into three broad categories (and time-horizons):
• process optimisations – short-term (chapter 2)
• engineering optimisations – medium-term (chapter 3)
• new technologies – long-term (chapter 4)
For each energy saving approach information is provided – based on data from live networks and/or simulations – on the size and scope of the potential energy savings.
