6. Broadband Applications 6. 1 Classification 6. 2 "Killer Application“ 6. 3 Case Study - Korea 6. 4 Next Generation Broadband Applications
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
6. 2 "Killer Application" All countries are looking for "KILLER APPLICATIONS" now. General consensus is multimedia, in particular video such as Television Movie Video Conference
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
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) P 2 P (more to come)
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.
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
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 Vo. IP Video (3) Mobile Internet 50% penetration 2. 5 G/3 G are taking off
8. 3 Greater China (1) Internet is Taking Off in China 57 millions in 2002(2 nd 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. 4 Singapore (1) Internet Is Fully Deployed (2) Broadband Penetration Is Around 10%
8. 5 South/South East Asia DSL and/or Cable Modem are coming up.
9. What’s Next? 9. 1 Next Generation Broadband Access VDSL ( 20~100 Mbps) FTTH ( 100 Mbps ~ 1 Gbps ) Remark : Looking for “killer applications” Digital Video, Interactive Video, … Replacing wired telephone (and television ? )
9. 2 Ubiquitous Network “Broadbandization” of wireline and wireless networks Integration of wireline and wireless networks. RFID Networking everything
9. 3 Wireless Network Integration or Natural Selection Mobile Phone Wireless LAN Bluetooth RFID
