IMT-2000 STANDARDIZATION
Michael H. CallendarChairman ITU-R Task Group 8/1
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
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 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
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
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
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
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
• 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

• 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
• 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

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
