This document discusses the standardization of IMT-2000, which aims to develop standards for 3G mobile networks and services in the 2000s. The objectives are to provide global services, reduce the digital divide, offer flexible services on fixed and mobile networks, and improve efficiency. IMT-2000 is expected to be dominated by data services and offer high quality voice and multimedia. Key expectations are flexibility, lower costs than 2G, improved efficiency, and global roaming. The document outlines the roles of ITU and regional standards bodies in developing IMT-2000 through consensus building and evaluations.

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

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. 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
