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

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

• 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
