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

(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 6.1 Classification

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

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

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)

- 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. 7. Current Status of Broadband Access

(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 8. Country Report 8.1 Korea

(1) Fast Growth in 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 8.2 Japan

(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 8.3 Greater China

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

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

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

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

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