1. Green Meter Announcement Thierry Van Landegem, Chairman, Executive Board of GreenTouch Thierry E. Klein, Chairman, Technical Committee of GreenTouch

2. GreenTouch background Green Meter Analysis: results of research study into future energy efficient networks Upcoming GreenTouch milestones AGENDA 13 May 20132

3. Data traffic drives energy consumption and is increasing exponentially Today’s networks are optimized for capacity not energy All the technology available today cannot put the brakes on this energy consumption growth Reducing energy consumption depends on optimizing networks for energy consumption SETTING THE STAGE 13 May 2013 3

4. Accelerate trend towards reduction in energy consumption Create technologies for a different kind of network Enable better performance with less energy Built a theoretical framework to calculate energy reduction potential of different technologies Committed to open innovation and collaboration to accelerate progress VISION 13 May 2013 4

5. Green Touch initiative formed in 2010 to invent the technologies needed Global research consortium with major industry leaders, equipment providers, operators, research institutions, academia Developing to provide a roadmap, architectures, protocols and technologies to improve energy efficiency in networks by 1000x compared to 2010 levels Invent these technologies and provide roadmap by 2015 MISSION OF GREENTOUCH 13 May 2013 5
