Alcatel Lucent: GreenTouch exceeding its targets and provides … –

GreenTouch ™, the global consortium whose mission is to significantly improve the energy efficiency of data communication networks, today announced its final results and unveiled new tools, technologies and architectures that will reduce energy consumption of communication networks in the coming years. During a ceremony in New York, GreenTouch revealed that his new approaches can multiply by more than 10,000 energy-efficient mobile access networks – a much higher number of the original objectives of the working group.

The consortium also announced research that will result in significant improvements in other parts of communication networks, such as core networks or fixed networks (wired) residential and enterprise. Through improved energy efficiency, the net energy consumption of communication networks should decrease by 98% between 2010 and 2020, despite a sharp increase in traffic. These savings represent the equivalent greenhouse gas emissions of 5.8 million cars.

“Time passed incredibly quickly since the start of GreenTouch project. But the most impressive are the results in just five years by our international team of scientists, academics and industry leaders to chart a course leading to more environmentally friendly networks, “said Thierry Van Landegem, President of GreenTouch. “With the public launch of tools and technologies that the market and academics can now use to design and deploy today and in the future more energy efficient communication networks. Our work will not only contribute to a more productive future and more environmentally friendly, but also connect many more people together. “

Formed in 2010, GreenTouch is guided by the vision and leadership of Bell Labs and aims to determine how to support the growth of communication networks in a more sustainable and economically viable way. At the time, the consortium was based on the premise that lower power consumption and greater energy efficiency can lead to a practical and wider use of renewable energy.

According to the SMARTer2030 report by GeSI ( Global e-Sustainability Initiative ), the information technology sector and communication (ICT), which includes the network of networks on which rests the global Internet, represent approximately 1.97% of carbon emissions on the planet in 2030. It is even possible that this figure is increasing because of the growing number of people looking to connect and access to more content, using new ways enriched. On the other hand, estimated the emissions avoided through greater use of ICT approaches would be almost ten times greater than the direct effect of emissions from ICT, which would have an impact on the possibilities for struggle against climate change and economic development with multiple services and applications emerging ICT.

During today’s event, GreenTouch announced that it was two tools at the disposal of businesses and other stakeholders who want to create more effective networks:

  • GWATT ( an interactive web application that offers a complete panorama of the entire GreenTouch technology portfolio and an end vision After the impact in terms of energy.
  • Flexible power supply model ( a power supply advanced model and a software tool that provide realistic power consumption figures for various types, configurations and scenarios current and future cellular base stations. This tool provides a technology roadmap for industry stakeholders.

The consortium members have also proposed key technology demonstrations that contributed to the results. Some of these innovations had not yet been announced by GreenTouch. Among the main contributions:

  • Beyond Green Cellular Generation (BCG2) – This architecture uses small cells (small cells) densely deployed and equipped with intelligent sleep modes, and completely separates the signal and data functions of a cellular network to dramatically enhance energy efficiency over the current LTE networks.
  • Large-Scale Antenna System (LSAS) – This system replaces the macro basis of today by a multitude of smaller antennas stations, low power and controlled individually to provide many bundles data per user, in order to optimize the energy efficiency of the system taking into account the power of radio frequency transmission and the energy to the internal electronics and signal processing.
  • Distributed Energy-Efficient Clouds – This architecture presents a new analytical optimization system to reduce energy consumption of content delivery networks (videos, photos, music and other large files – which constitute 90% of traffic on the network cores). This creates a new mini-clouds architecture distributed closer to the user, instead of large data centers.
  • Green Transmission Technologies (GTT) – This set of technologies is the best compromise between spectral efficiency and energy efficiency of mobile networks by optimizing the energy efficiency of different technologies such as MIMO ( Multiple-In Multiple-Out) for single or multiple users, multipoint transmissions coordinates, and the alignment of the interference.
  • Bit Interleaving Cascaded Passive Optical Networks (PON CBI) – This development extends the Bi-PON technology (Passive Optical Network Bit Interleaving) into a Bi-PON architecture cascade that allows anyone which network node (access networks, devices, metropolitan) effectively treat only the part of the traffic under this node, which significantly reduces the total energy consumption of the entire network.
