4 Mobile Operators Challenge Short-Term Challenges Long-Term Challenges TOTAL COST OF OWNERSHIP Affording Growth & Differentiation Despite Flat or Decreasing Revenues ENERGY Oil Prices? Production SUSTAINABLE DEVELOPMENT End-of-Life Usage Demonstrating Engagement Setting a Strategy Making Business in a brand new world Energy Efficiency Towards Low OPEX and TCO Energy Efficiency Towards Sustainable Development DOING MORE IN AN ENERGY-LESS WORLD 4 September 22, 2008

5 Addressing Energy at All Network Layers ADVANCED EQUIPMENT FEATURES OPTIMIZED SITE ENGINEERING SMART NETWORK ARCHITECTURE & ENGINEERING More Integration & Intelligence using less Energy Less Power Wasted (thermal management, interfaces, etc.) Alternative Energy Production & Storage More Capability using Less Equipment DEDICATED SERVICES Energy Efficiency Assessment, Network Transformation, etc. 5 September 22, 2008

6 Advanced Equipment Features Hardware Hardware Integration the basis to reduce energy consumption 6 September 22, 2008

7 Wireless BTS Power Amplifier Efficiency Trend Efficiency 50% 45% 40% 35% 30% 25% 20% 15% 10% 5% 0% LDMOS / GaAs Doherty / Drain Modulation / Class F Trend driven by device technology improvement Class S / RF-to-RF Conversion Voltage Follower Trend driven by device technology improvement and high efficiency improvements Year 7 September 22, 2008

8 Advanced Equipment Features Reduce Cell Site Power Consumption - Distributed BTS Energy benefits from Remote Radio Heads (RRH) include: Near zero db feeder loss with RRH mounted close to the antenna (compared to 3dB loss with power amplifier installed at ground level) halve the energy loss Elimination of air conditioning equipment 8 September 22, 2008

9 Avoiding the Coverage Tax Power consumption 100% 70% Traffic Coverage Traffic Load From 0% to 100% Min. 70% of BTS instantaneous power consumption: for service coverage Wasted energy Wasted money Power savings from Alcatel-Lucent data CAN T WE JUST TURN THEM OFF? 9 September 22, 2008

10 Advanced Equipment Features Software Intelligence to adapt energy consumption to the traffic carried Energy Consumption WITHOUT Dynamic Energy Savings WITH Dynamic Energy Savings Saved energy Network traffic At the right level: 00.00hrs 12.00hrs 24.00hrs responsiveness Component level (CPU, FPGA) Board level (Channel Element) Cell level (Carrier) Site level (Base station) Lowering the energy required with reduced traffic by switching-off components Ensuring Quality of Service when traffic / need returns 10 September 22, 2008

11 Smart Network Architecture & Engineering Beamforming for Wireless Networks Smart Network Engineering to Optimize Radio Energy Usage WITHOUT BEAMFORMING WITH BEAMFORMING Reducing by up to 40% the amount of equipment required to cover a given geographic area Avoiding waste energy in useless radio coverage 11 September 22, 2008

12 Optimized Site Engineering Thermal Management Reducing the power wasted to cool / maintain the equipment Reduce it Direct air cooling system in outdoor wireless base station cabinet eliminates need for air conditioning Move it Liquid cooled cabinets dissipate heat more efficiently using less power Use it Energy harvesting from waste heat Hot IC IC Thermoelectric Module V Useful electricity is generated by Thermoelectric Module Cold 12 September 22, 2008

13 Wireless Base Station Cabinet Solutions Efficient Air Cooling System Two options WITHOUT AIR CONDITIONING Optimised heat exchanger up to 45 C with full configuration Heat exchanger located in front door Direct Air Cooling System up to 55 C with full configuration Membrane filter located in front door WITHSTANDING HIGH ENVIRONMENT TEMPERATURES WITH MINIMUM POWER CONSUMPTION 13 September 22, 2008

14 Optimized Site Engineering Alternate Energy Sources Leveraging field experience and innovation to make renewable energy a wider reality ALTERNATE ENERGY EFFICIENCY IMPROVEMENT + TELECOM NETWORKS ENERGY EFFICIENCY IMPROVEMENT ENLARGE THE RANGE OF APPLICATION OF ALTERNATIVE ENERGIES FOR TELECOM Source: BP Solar. 14 September 22, 2008

15 Alternate Energy Solutions Solar Energy 200 th Alcatel-Lucent solar-powered BTS site! Bettenty Island, Senegal On top: Affordable solar panel surface thanks to very low power consumption Batte ries BTS CBO + 3 GSM antennas + 1 FH 1.2m antennas + 1 working platform Solar panel Innovative Site Designs Answering Field Feedback TURNKEY APPROACH AND FIELD EXPERIENCE ARE KEY 15 September 22, 2008

16 Conclusions Transforming Communications for a Sustainable Planet Eco-sustainability is the defining challenge of our times that telecommunications can play a major role in solving. Products & Services focus on energy to address the short and long term eco-sustainability challenges.
