22. Top measures of ICT energy efficiency From transformation to excellence to customer satisfaction
Energy-efficient NGN infrastructure
Sustainable customer solutions
NGN/All-IP transformation

Go with the technology (e.g. 15% improvement p.a.)

23. Common site concept(Fixed & Mobile, eventually IT) 24. Improved housing efficiency(UPS, HVAC, building practice) 25. Load adaptive network ops (Power mode, starting with fix & mobile access DSL & RAN) 26. Energy efficient CPE/HGW (e.g. functional integration, thin clients, ) 27. Green home networks(Energy Control Plane, ) 28. Green applications(Green App, smart homes etc.) 29. Minimized parallel operation of NGN and legacy platforms(turn off PSTN, SDH & ATM) 30. Capacity adjustment (from 100 ->50% market share) 31. Platform live cycle management. (e.g. mobile network)
