energy costs are among largest OPEX items for cellular carriers
• Limited energy supplies
• Energy costs rising
• Ethical consumerism becoming more mainstream and sustainability reporting to be expected from corporations
• Increasing government regulation and subsidies for ecologically friendly solutions. Including e.g. emissions-trading schemes or mandatory network sharing

• Nokia Siemens Networks’ unique OSC feature allows to reduce BTS power consumption up to 50%
• OSC-DHR introduces the concept of Dual Half Rate• Dual Half Rate allows multiplexing of four AMR-HR users to one timeslot at the air interface
Up to 50% power reduction with OSC (orthogonal Sub-channel)AMR HR OSC

• A unique and innovative feature which up to doubles the BTS traffic handling capacity in synchronized BTS clusters
• DFCA is a powerful algorithm in BSC which ensures optimum radio channel allocation for every new call and incoming handover
NSN’s unique DFCA (Dynamic frequency channel Allocation) feature

Cell_FACH = >100 mA
Active = >200 mA
Shorter time in active mode means longer battery life!Almost doubled battery life observed in field with Cell PCH!
