What is IMT-2000 ?

Communication Anywhere-Anytime-Anytype

Graphic Source : ITU-T document


Wireless Mobile Data Services Evolution

One-Way Data Communication Services => Two Way Data Communication in Paging System

Cellular modem Services => CDPD data Services

Wireless LAN => Wireless Mobile LAN

ARDIS, RAM=> Commercial Mobile Data Service Networks

Handheld Device and Mobile Terminals drives the Wireless Mobile Data Communication needs


High Mobile Data Services Costs<= Specialized Terminals and Infrastructure Systems

Specialized Applications and Low Speed<= Not End-User applications like an Internet Access

Small Coverage<= Focused on Business Area

Data Only Service Terminal<= requires Additional Cellular Phone

Barriers for the Mobile Data User Subscription

Data Oriented Mobile Data Communication


2nd Generation Mobile Data Services Evolution

Digital Cellular/PCS makes Paradigm shifting forMobile Data Services

Higher Cost => Low Cost

Specialized application=> Wellknown Landline Data Communication Services

Large Coverage=> Cellular & PCS Service Coverage

Voice /Data Services=> Multiple or Simultaneous Service

Drives the Mobile Data User Penetration


Cellular/PCS Data Speed Evolution (to IMT-2000)

Low Speed Data Medium Speed Data High Speed Data

8Kbps ~ 14.4Kbps 32Kbps ~ 64Kbps 144Kbps ~ 384Kbps

Wireless Mobile Internet on PCS

GWR(Gateway Router) : Interface the Internet and has its Internet Network ID, Each Mobile Host may have Internet IP address which is one of the host identifier within the GWR’s Network ID. This is a gateway between “Mobile Internet” and “Internet” and is theanchor system for the Internet IP datagram transmission. May act as IP manager
