  1. Green Technology in Telecom Sector Samar Mittal Head of Global Services Sales, Nokia Siemens Networks

  2. Setting the Scene Decrease energy consumption by using smarter equipment Reduce equipment by deploying smart features Smartly reduce power consumption in end user devices More efficiency using renewable energy sources in a smart way

  3. energy costs are among largest OPEX items for cellular carriers Market drivers Efficiency drivers Building energy-efficient networks • 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 Utilizingmodern technology Renewableenergy sources Effectiveoperations

  4. Energy is used mostly in BTS sites Share of energy consumption BTS sites 65% Corporate sites12% Offices, facilities, etc. 12% Retail 1% Maintenance vehicles 1% Switch sites21% Source: ABI Research

  5. Setting the Scene Decrease energy consumption by using smarter equipment Reduce equipment by deploying smart features Smartly reduce power consumption in end user devices More efficiency using renewable energy sources in a smart way

  6. Flexi Base Station enables Green Radio:70% lower energy consumption and CO2 footprint Power consumption of a complete GSM & WCDMA BTS site • Green over the entire life-cycle • Production • 80% less material • Transport & installation • 25 l, <25 kg modules minimize logistics related environmental impact • Operation • 70% less energy • Extended operation • remote software-upgrade instead HW-exchange • End-of-operation • 95% recyclable Low power consumption enables RES 1470W >70% WCDMA GSM Multiradio 455 W 1500W 800 W 790 W 2010 2005 2008 traditional BTS design Measurement conditions: WCDMA 1+1+1@20W WCDMA BTS HW with 50% load and 4+4+4GSM (2% blocking, DTX and DPC active)

  7. Driving down energy consumption of controllers RNC energy efficiency development [W/Mbps] 20 15 Energy consumption per Mbps [W] 10 5 2.1 0 2008 2006 2009 2010 2007

  8. Setting the Scene Decrease energy consumption by using smarter equipment Reduce equipment by deploying smart features Smartly reduce power consumption in end user devices More efficiency using renewable energy sources in a smart way

  9. Up to 50% power reduction with OSC (orthogonal Sub-channel) OSC AMR HR Dual Half Rate voice codec Half Rate voice codec Link Adaptation OSC-0 OSC-1 2 users per TSL 4 users per TSL • 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

  10. DFCA NSN’s unique DFCA (Dynamic frequency channel Allocation) feature • 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

  11. Setting the Scene Decrease energy consumption by using smarter equipment Reduce equipment by deploying smart features Smartly reduce power consumption in end user devices More efficiency using renewable energy sources in a smart way

  12. Nokia Siemens Networks handles signaling differently Competition Active = >200 mA inactivity timer DCH/HSPA inactivity timer CELL_FACH Cell_FACH = >100 mA 30 signalingmessages Idle = <5 mA IDLE IDLE 2s Nokia Siemens Networks DCH/HSPA inactive Active = >200 mA 12 signaling messages inactive CELL_FACH Cell_FACH = >100 mA 3 signaling messages Cell update (RRC) Cell update confirm (RRC) UMI confirm (RRC) Cell_PCH = <5 mA PCH PCH Shorter time in active mode means longer battery life! Almost doubled battery life observed in field with Cell PCH! <0.5 s

  13. Setting the Scene Decrease energy consumption by using smarter equipment Reduce equipment by deploying smart features Smartly reduce power consumption in end user devices More efficiency using renewable energy sources in a smart way

  14. Opportunities for CSP,IP: -cover new potential markets in rural and remote areas -improve network availability and carbon foot print reduction Solar Panel Wind turbine Grid Battery Generator GreenEnergyControl Nokia Siemens Networks Off/Bad-Grid Site Solution • Dramatically reduces the power related network outages • Provides connectivity to rural/remote areas • Fuel consumption reduction • Increases battery life • OPEX reduction Renewable energy sources and green energy control to manage the site

  15. Nokia Siemens Networks Green Energy Control • Opportunities for CSP, IP: • reduce OPEX by remotely managing energy sources • efficient control and monitoring of multiple energy sources • charging & discharging cycles under control • Benefits for CSP,IP: • Up to 70% of OPEX savings • Up to 50% reduction of carbon footprint Interfaces all power sources and smartly manages performance remotely
