  14. 6. Broadband Applications 6.1 Classification 6.2 "Killer Application“ 6.3 Case Study - Korea 6.4 Next Generation Broadband Applications

  15. 6.1 Classification (1) General Internet Access- Browsing    - Messaging    - File Downloading    - Games(2) Audio and Video- Audio Delivery    - Internet Telephony    - Video Delivery    - Video Conference(3) New Applications- Peer-to-Peer Applications    - Distributed Work     - Distance Learning    - Home Content

  16. 6.2 "Killer Application" All countries are looking for "KILLER APPLICATIONS" now.General consensus is multimedia,in particular video such asTelevision  Movie  Video Conference

  17. 6.3 Case Study - Korea 6.3.1 Killer Applications - First Wave   (1) Heavy Internet users(always on)     (2) Adult content     (3) Stock exchange(Day Trader)     (4) Online game 6.3.2 Killer Applications - Second Wave      (1) Broadband Portal     (2) Education     (3) Music     (4) Movie     (5) Television Program

  18. 6.4 Next Generation Broadband Applications ( or Why do we need Gigabit Ethernet? ) (1) Higher Definition Video Streaming Down loading (2) High Definition Video Conferencing and Class (3) High Definition Online Game (4) Bulk File Transfer (5) P2P (more to come)

  19. 7. Current Status of Broadband Access • Broadband access with always-on capability • becomes social infrastructure in Korea with • other Asian countries following. • (like telephone, and television) • Virus and intrusion become serious social • problems since general users with always-on • connection are not ready for these problems.

  20. 8. Country Report 8.1 Korea (1) Broadband Is Fully Deployed    - 60% of household    - Dialup has become "horse carriage"    - Broadband become social infrastructure like       telephone or automobile or television(2) Looking for Next Generation Broadband    - VDSL(>10 Mbps) vs FTTH(100 Mbps~)    - LAN(~FTTB) deployment at 10~15%(3) Side Effects    - Intrusion    - Virus(4) Mobile and Wireless     - Mobile Internet is taking off    - Major deployment of wireless LAN

  21. 8.2 Japan (1) Fast Growth in 2002     3 millions --> 8 millions (--> 11 millions in 2003)      Tough price competition (~ $20/month) (2) Looking for Killer Applications     VoIP     Video(3) Mobile Internet     50% penetration     2.5G/3G are taking off

  22. 8.3 Greater China (1) Internet is Taking Off in China     57 millions in 2002(2nd after USA)     Expected to take over USA in 2005     Beijing and Shanghai are similar to Korea and Japan(2) Hong Kong and Taiwan Are Following Korean Pattern     ~10% penetration and taking off

  23. 8.4 Singapore (1) Internet Is Fully Deployed(2) Broadband Penetration Is Around 10%

  24. 8.5 South/South East Asia DSL and/or Cable Modem are coming up.

  25. 9. What’s Next? 9.1 Next Generation Broadband Access VDSL ( 20~100 Mbps) FTTH ( 100Mbps ~ 1 Gbps )Remark : Looking for “killer applications” Digital Video, Interactive Video, … Replacing wired telephone (and television ?)

  26. “Broadbandization” of wireline and wireless networks Integration of wireline and wireless networks Networking everything 9.2 Ubiquitous Network . RFID

  27. 9.3 Wireless Network Integration or Natural Selection Mobile Phone Wireless LAN Bluetooth    RFID
