© 2012 Mobile VCE Green Radio Project Outcomes There is no one magic bullet to save energy  Rather we need to combine a range of solutions

© 2012 Mobile VCE Going Beyond Green Radio Tech  Future network architectures  Small cells vs Cloud base stations  Self-organising and self-healing networks  Energy efficiency of handsets  Smartphones but not-so-smart battery technology  Finding the balance between the network and handset  Future energy sources  Ensuring reliable energy sources beyond 2015  Renewable energy/off grid solutions  embodied vs operational energy consumption  Spectrum management issues  Coordination of multiple licensed spectrum bands that are opening up via auctions and unlicensed spectrum  Radio technologies to handle all the available bands!

© 2012 Mobile VCE Green ICT Applications  Future Cities  Ubiquitous, invisible sensors  Information harvesting and gathering  Intelligent Cyber-physical systems  Sustainable low carbon environments  Digital Economy  Reliable information infrastructure  Low Carbon Manufacturing  Sustainable communications systems  Intelligent Transport Systems  Low Carbon Vehicles and Transport  Driverless Transport Systems  Smart Roads and Junctions
