Zenitthys, an innovating solution to reduce environmental impacts of telecom networks development

Published on in Latest News

Conflans-Sainte-Honorine, FRANCE – 8th December 2014 – ARELIS and Thomson Broadcast part of Arelis Group today announced the development of the ZENITTHYS (Zero Energy Network In Telecom and Television Hybrid System) project supported by the General Environment Directorate.

The European Commission has approved on April 30th in Brussels the funding of €282.6 million for 225 new projects under the LIFE+ program, the European Union’s environment fund. This financing which aims at achieving sustainable growth through investment in a low carbon and resource efficient economy, represents an essential financial support for added value environmental and nature conservation projects with a significant increased budget, for the period 2014-2020.

ZENITTHYS project selected with 224 other projects among 1468 applicants aims at drastically reducing carbon footprint and other environmental impacts of telecommunications networks such as visual and electromagnetic pollution. This will be achieved with the development of an innovative hybrid pilot station that benefits from recent advances in electronic devices, signal processing and renewable technologies.

This 4G and television broadcasting pilot station, solar and wind energy, allows to converge telecom and terrestrial broadcasting for a drastic decrease of transmission sites. While the immediate proximity of antennas causes besides visual disturbances, strong electromagnetic pollution for the inhabitants, an impact on human beings rarely addressed by latest technical developments, this type of station can be installed in remote areas without access to the grid.

In pursuit of the European Opéra-net2 project aiming at developing a hybrid open test site producing carbon-free energy while optimizing energy efficiency for 4G mobile networks, ZENITTHYS offers a viable economic and social alternative to the duplication of telecommunications and broadcasting stations. There are already 38,000 base stations in France for both 3G and 2G network and almost 12 500 additional authorized ones with the 4G network deployment. Moreover the use of high-efficiency amplification technologies combined with application sharing on a site would lead up to 40% energy savings for a national network. .

Beyond this rationalization, it is primarily a society response to these low power but high gain base station installed at the heart of cities exposing inhabitants to load up more than 10V / m. Indeed a hybrid telecom/broadcast stations located on the edge of cities of cities would dissociate mobile signal reception kept in the base stations from emission which then exposes populations to less than 0.6 V / m charges, i.e. the prevention threshold recommended in 2011 by the Council of Europe (1815 Resolution (2011)) for the long-term exposure to microwaves indoor levels. The reception quality would be maintained at a high level while the indoor penetration would be preserved through femtocells.

Pascal VEILLAT, Chairman of Arelis Group and Thomson Broadcast is pleased that ZENITTHYS project do bring together telecom operators and broadcasters and create strong synergies to offer renewable energies sustainable networks. « The future is green energies used in sustainable efficient systems which may integrate short- and long-term storage for a complete autonomy. We are strongly committed to ZENITTHYSs and all entities of Arelis group are involved» adds Pascal Veillat.

4G and television broadcasting station design

With a long experience in software development and signal processing, Thomson Broadcast provides a platform which manage both mobile and digital video signals. Meanwhile, expert in amplification linearity corrections for television transmitters, Thomson Broadcast will achieve an excellent linearity whereas the mobile signal is much less filtered than the television one. Responsible for many deployments of complete national transmission system, Thomson Broadcast conducts a comprehensive study on the antenna systems for an integrated transmission capability.
