  1. Mobile Data Services Evolution to the 3rd Generation Mobile Communications Global Summit Japan 3rd Generation Mobile Comms & IMT-2000 17&18 March, Keio Plaza Inter-Continental Hotel, Tokyo, Japan Byung-Keun Lim, Ph.D. e-mail : bklim@ lgic.co.kr Senior Research Engineer, R&D Center, LG Information & Communications

  2. What is IMT-2000 ? Communication Anywhere-Anytime-Anytype Graphic Source : ITU-T document

  3. Wireless Mobile Data Services Evolution Handheld Device and Mobile Terminals drives the Wireless Mobile Data Communication needs 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

  4. Data Oriented Mobile Data Communication • 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

  5. 2nd Generation Mobile Data Services Evolution • Digital Cellular/PCS makes Paradigm shifting for • Mobile 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

  6. Cellular/PCS Data Speed Evolution (to IMT-2000) Low Speed Data Medium Speed Data High Speed Data 8Kbps ~ 14.4Kbps 32Kbps ~ 64Kbps 144Kbps ~ 384Kbps Text data, Graphic Remote Login, E-mail, Text mode Internet Graphic,Image Internet, Internet VOD Image,Video Multimedia, VOD, Now ~ 1999 2000(IMT-2000) ~ • Data Speed Performance will reach to the IMT-2000 grade, • Data Service Applications will be completely matured before • the Commercial Deployment of the IMT-2000 system.
