1. 1 WIRELESS ACCESS FOR THE 21ST CENTURY Anywhere - Anytime WIRELESS ACCESS FOR THE 21ST CENTURY Anywhere - Anytime IMT-2000 STANDARDIZATION Michael H. Callendar Chairman ITU-R Task Group 8/1

2. 2 IMT-2000 OBJECTIVES Global Service Capabilities in 2000s Terrestrial & Satellite Components Reduce the Telecommunications Gap Flexible/Seamless Service Provision Wider Range of Services/Terminals Fixed/Mobile and Public/Private Improved Operational Efficiencies

3. 3 MARKET FACTORS Market for IMT-2000 is truly Global Convergence of Wired/Wireless Networks Using Common Platforms Today’s Mobile Population Is Less Than 10% of That Forecast for 2015 Regional “Footprints” Today Should Not Unduly Restrict Technologies for a New ITU Standard for the 2000s

4. 4 IMT-2000 Dominated by Data Services Data Communication Between Devices Internet and Multimedia High Quality Voice Flexible Mixed/Multi-Service Provision Based on Compliance to ITU IMT-2000 Recommendations IMT-2000 SERVICES

5. 5 KEY EXPECTATIONS OF IMT-2000 Flexibility for Data & Multimedia Services (incl. Internet-based) Lower Cost Than 2G for “Basic” Services Plus New Service Capabilities Service Transparency/Global Roaming Significantly Improved Operational Efficiency (esp. Capacity/Spectrum Efficiency)

6. 6 FLEXIBILITY Service Provision –Multiple Service Categories –Higher Bit Rates –Asymmetrical –Multimedia Network Evolution –Common Platforms –Radio Independence –Mixed 2G and 3G Spectrum Management –Simple Reuse Plan –Bandwidth on Demand –Coexistence with 2G

7. 7 OPERATIONAL EFFICIENCY Spectrum Efficiency Improvements –Multiplexing Gain for Mixed Services –Technology Improvements –Space Dimension - Smart Antennas –Interference Cancellation Coverage Efficiency –Same Sites –Mixed 2G and 3G –Range with Higher Bit Rates Cost Structure –Optimize Resource Utilization –Bandwidth on Demand –Lower Cost Floor for Basic Services.

8. 8 3G - ROLE OF THE World-wide Spectrum Coordination Policy/Regulatory Harmonization International Standards for IMT-2000, Including Key Access and Network Interfaces Provide Foundation, Framework and Catalyst For 3G Convergence Across Regions And Technologies

9. 9 Teamwork with the ITU in Development of IMT-2000 Standards Harmonize Regional Input Contributions to the ITU Development of Specific Regional Requirements Within the IMT-2000 Family of Systems Evolution of Regional Pre-IMT-2000 Standards Towards IMT-2000 Capabilities ROLE OF THE REGIONAL STANDARDS BODIES

11. 11 Outside ITU Inside ITU RTT SELECTION PROCESS Consensus building Review Evaluations Request for Proposals Implementation of Recommendations Evaluation Proposals Development of Recommendations Develop, Submit & Evaluate Technologies

12. 12 Cost Reduction via Economies of Scale Enabler for “Globally Capable” Terminals (Including Embedded “Invisible” 3G Devices) Minimizes Global Market Fragmentation Reduces Barriers to Global Service Provision/Roaming (Technology Islands) Avoids Precipitating Unnecessary Complexity of Global Wireless Networks and Terminals IMPORTANCE OF RADIO CONVERGENCE

13. 13 Coexistence with Second Generation Systems, Especially in North America Vendors’ Desire for IPR Advantage Negotiating Agreements between Regional/Technology-based “Camps” Intensity/Diversity of 3G Standards Activities Is Stretching Scarce Resources ITU Consensus Building Can Be a Catalyst for Win/Win Convergence Operator Agreement on Value of Convergence Is Key to Success CHALLENGES AND OPPORTUNITIES
