Bell Labs study claims to halve mobile network energy costs

27 January 2015 |


Alcatel-Lucent’s Bell Labs has completed its IntelliSpekrum research project and discovered that mobile networks can deliver energy savings of up to 50% by deploying a mixture of macro and small cell radio base stations.

The IntelliSpektrum project was designed to prove that as mobile traffic dramatically increases, base stations can be adapted to manage this traffic and save energy, with no loss to end-user service quality. 

“We are committed to the research and development of energy-efficient products and technologies that offer improved network performance,” said and Marcus Weldon, president of Bell Labs and CTO at Alcatel-Lucent.

“Findings from the project underscore the critical importance of small cells and prove that by deploying a mix of base station radios operators will see better energy efficiency and increased network performance – thereby improving their customers’ experience and increasing efficiency.”

Bell Labs claims that the project showed significant energy savings in heterogeneous (HetNet) mobile networks, those with a mix of Macro, Metro Pico and Femto base stations.

HetNets are able make more efficient use of infrastructure because they are able to adapt to high and low load traffic environments.

Bell Labs worked with the Fraunhofer Institute for Applied Solid State Physics, the Fraunhofer Heinrich-Hertz-Institute and Intel Mobile Communications on the project.

“In order to deliver an excellent user experience, future wireless networks will need more intelligent devices,” said Stefan Woff, VP of the platform engineering group at Intel.

“This project provides some new key features in order to make that happen. This project adds to our ongoing efforts to increase power efficiency and user experience of our wireless communication.”
