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
2
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. IMT-2000 SERVICES
• 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
4
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)

–Lower Cost Floor for Basic Services. 7
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
8
9. ROLE OF THE REGIONAL
STANDARDS BODIES
• 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

12. IMPORTANCE OF RADIO
CONVERGENCE
• 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
12
13. CHALLENGES AND
OPPORTUNITIES
• 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

14. CONCLUSIONS
• ITU/Regional Standards ‘Team ‘
• Radio Convergence - Key to Realizing Cost
Reduction/3G Market Growth
• Significant Challenges Remain to be
Overcome but a “Window Of Opportunity”
Exists
• Operator Commitment to Convergence
Needed to Ensure Window Is Not Missed
