19. - 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

20. (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

21. (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 8.2 Japan

22. (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

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