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!
