How to improve energy efficiency

Discover our RAN modernization guide

Energy efficiency

Energy efficiency is on top of CSPs’ agenda – together with the increased capacity demands and the need to address the challenge of exponential data traffic growth. That’s why we are constantly innovating our portfolio and integrate our solutions with renewable energy sources. So, we improve energy efficiency while increasing performance and accelerating the build of nationwide, fully performing 5G.

Our approach to energy efficiency

Data traffic on mobile networks continues to grow - but that doesn't mean energy use and related emissions in mobile networks need to grow along with it. CSPs have a pressing need to consider how to evolve their current networks, while reducing energy consumption and carbon emissions.

To reduce the overall networks energy consumption, break the energy curve, our holistic approach consists of these three steps:

  • Sustainability in the center of network planning
  • Expand and modernize the existing network while scaling up 5G
  • Use AI/ML and automation for intelligent operations to boost energy savings and secure user experience


“Ericsson is reducing the embodied carbon emissions of its own products to help CSPs meet the Net Zero challenge. We are enabling our customers to develop and expose new network capabilities with the common goal of providing affordable and sustainable connectivity for all.”

- Freddie Södergren, Head of Technology and Strategy, Ericsson Networks
