  5. (Unit:Million$) Infra Terminal service Source : Gartner, 2002.4 Background wireless internet services • Forecast of global wireless internet markets • Services leads the market(annually 10.2% growth)

  6. Background wireless internet services • Development trends of Wireless Internet Services `02 `03 `04 `05 Image, Sound Multimedia, GPS Convergence of Wire & Wireless Multimedia Introduction Multimedia elaboration Multimedia Proliferation Main Services • MMS (moving picture mail) • VOD/ MOD • Interactive Network • Game • LBS/ M-commerce/GPS • 3G and 3D (Video & Audio) • M-commerce based on LBS • Multimedia Broadcasting • MMS (photo mail) • Network Game • MIDI Ring Tone Network • 1x • 1x EVDO • GPRS • WCDMA(384Kbps) • 1x Upgrade(307kbps) • Open Platform • HSDPA • 1x EVDV • EDGE Issues on Terminal • Color Display • MIDI • Moving picture • Camera • GPS • W-LAN • Broadcasting receive Chip • Commercial OS (features ofvPDA) • VOD: Video on Demand • MMS: Multimedia Messaging Service • LBS: Location based Service • EDGE(Enhanced Data Rates for Global Evolution) • HSDPA(High Speed Downlink Packet Access)

  7. Background the status of Korean market • Groth of domestic mobile telecommunication industry • subscriber of mobile phone and wireless internet(2002. 10) (Unit: 1000, %) • reference : MIC

  8. OEM Drivers App Module Platform Wireless Internet LaunchPadTM Suite (Multimedia, UI, Storage, Positioning, Connectivity) Sockets EFS CallMgr REX Hand-Set SW Background wireless internet platform • Wireless Internet Platform • Is a common runtime environments for application programs • provides execution of downloaded programs through off-line • supports various multimedia services(high-level graphic, sound) • dynamic downloading of applications • provides rich and fast services to user • provides Cross-platform compatability

  9. Background various wireless internet platform in Korea • Each carrier has it’s own platforms • Contents Provider must develop programs for each platform • Manufacturere must porting each platform every new terminal • Contents provided to users are determined by carriers

  10. Vastly heterogeneous application run time environment SK Telecom KTF LG TeleCom GVM SK-VM MAP BREW CLDC/MIDP Content Provider Content Provider Content Provider Handset Vendor Handset Vendor Handset Vendor       • The RFP, containing the wish lists of the carriers, handset vendors and application developers, was disseminated by KWISF to platform developers • Development project for the specifications and implementation began in 2001, with ETRI as the project manager SK Telecom / SK IMT KTF / KTiCOM LG TeleCom WIPI Implementation1 , WIPI Implementation2 ,    WIPI Implementationn Content Provider Content Provider Content Provider Handset Vendor Handset Vendor Handset Vendor       WIPI Initiation

  11. WIPI means…… • Wireless Internet Platform for Interoperability • Developed by KWISF • V1.0 was announced in February 2002 • adapted as a TTA standard in May 2002 • V1.2.1 was announced in May 2003 • Currently WIPI 2.0 is developing in KWISF

  12. SK Telecom / SK IMT KTF / KTiCOM LG TeleCom WIPI Implementation1 , WIPI Implementation2 ,    WIPI Implementationn Content Provider Content Provider Content Provider Handset Vendor Handset Vendor Handset Vendor       WIPI It’s goal • For wireless carriers • Availability of broader range of compelling contents for delivery • More downloads through within service and roaming • For handset vendors • Reduction in engineering cost and time • If outsourcing, availability of broader choices of implementers • For content/application developers • More focus and resource allocation for designing the substance of contents • Wider distribution channel

  13. WIPI Architecture Application Manager : retrival, download, install, execution, removal of app. and mgmt .of life cycles of app. API Manager : add or delete the Basic APIs through download App. & API Manager IM MMS Group Chatting Character/Bell Video Streaming Email Location Based Games       APIs and Components that are added or renewed through dynamic download Dynamic Component Basic API WIPI Run-time Engine HAL (Handset Adaptation Layer) Handset Hardware & Native System Software Hardware abstraction layer for independency of platform from a handset APIs for application program developers and they sopports C and Java™ programming languages Java™ is a trademark of Sun Microsystems Inc. in the US and other countries.

  14. WIPI Technical Features • Supports multiple programming languages • C, Java • High speed binary runtime environment • Java program also must run as a binary • Running multiple application programs • Each program has it’s own address space • Supports IPC between applications

  15. WIPI Technical Features • Dynamic loadable modules of APIs or components • High level memory management • Supports shared memory • Memory compaction and Garbage collection • 3 levels of security • 3 levels are applied with APIs and file systems

  16. WIP Development of WIPI V2.0 • Extend the mobile platform special group in KWISF to promote the enhancement of WIPI • reorganized into 3 WGs and 1 TFT • over 40 companies including foreign companies join those WGs • Motorola, SUN, IBM, Microsoft are in WIPI 2.0 TFT • In WIPI 2.0 TFT, • the TFT meeting for WIPI 2.0 is held at every Friday. • the first draft will be produced by Oct. 31.

  17. WIPI New Features in 2.0 • Supports the compatiblility with J2ME(CLDC/MIDP) • General I/O interface • supports OFDA, Camera, one-chip • device open/close/control functions • data communication, register of callback function • Terminal Resource • management of terminal resource • group management of terminal resource • security of terminal resource

  18. WIPI New Features in 2.0 • PIMS and Camera API • 3 levels are applied with APIs and file systems • Supports vcard format • Supports OTA as a protocol between terminal and server • etc • high-level image APIs • more mathematics APIs

  19. WIPI Commercialization Status • Currently, 2 carriers produce 4 models of WIPI phones since this June. • SKT services 301 contents • KTF services 38 contents • 584,00 number of users • Until at the end of this year, 10 more models will be produced as their plan. <SKT, SKTeletec/IMT2000> <LGT, LG-LP1900>
