The mobile industry today is in a state of constant growth. To adapt to these changing dynamics, operators are adopting multi-standard, multi-band, and multi-layer network architectures - rendering box-to-box energy comparisons relatively meaningless.
Rethinking energy performance: increase app coverage, lower energy

To achieve sustainable energy reductions, operators must address energy performance from a holistic perspective, considering impacts and improvements across their entire network. This paper discusses how operators can increase both the coverage and capacity of their mobile networks while reducing their energy use on the road to 5G. Rethinking energy performance means understanding the effects of both energy policies and mobile broadband growth and adopting a systematic approach that addresses today’s installed base and tomorrow’s network evolution.
