Nokia Siemens Network (NSN) has set up a base station for German mobile service provider E-Plus that is powered by renewable energy.
The transmission plant relies on a combination of solar and wind power, supported by fuel cell and deep-cycle battery technology. It is the first base station to operate without using Germany’s grid electricity.
“With this innovative energy concept, we show how mobile-phone transmission sites can become carbon neutral,” says E-Plus chief technology officer Rafael Markiewicz.
NSN, headquartered in Espoo, Finland, has provided a tracking system that follows the sun and turns the maximum surface of the solar panels towards it to increase solar energy production for the site’s operation. NSN’s remote energy management enables the monitoring of all green-energy components. In addition, the possibility of remotely maintaining and installing new software obviates the need to visit base station sites, further preventing carbon dioxide emissions.
Grid-independent base stations can be used at locations lacking an affordable energy grid connection to cover so-called ‘white spot’ areas and increase the broadband penetration.
E-Plus is the third-largest mobile network operator in Germany. More than 20-million customers use its network to make calls and send text messages or data.
NSN is a leading global enabler of telecommunication services. Focusing on innovation and sustainability, the company provides a complete portfolio of mobile, fixed and converged network technology, as well as professional services, including consultancy and system integration, deployment, maintenance and managed services. It is one of the largest telecommunications hardware, software and professional services companies in the world. It operates in 150 countries.
The State Grid Corporation of China is building a Quinghai-Tibet power grid to improve and optimise power allocation in the region. It has selected NSN’s optical transmission platform to help ensure con- sistent power supply for the world’s highest power transmission line. The power grid is the largest con- struction project in the region and is scheduled to be operational by mid-2012.
Construction of the Qinghai-Tibet inter- connection project began in July 2010. The highest elevation in the project is at 5 200 m, with 87% of the construction area being above 4 000 m.
NSN’s dense-wave division multiplexing (DWDM) solution, comprising hiT 7 300 and TransNet DWDM planning and automation tools, provides a cost-optimised, flexible and automated platform, offering a viable answer to extensive traffic demand, reconfiguration and cost pressure issues. The design principle of the DWDM platform is based on high modu- larity and high reuse, creating a single platform from metro to core.
