5 Two Sides of Broadband Internet Business in Korea Threat Revenue: Saturating market with flat rate Expenditure: Increasing CAPEX/OPEX due to doubling traffic High customer expectation level: - avr. ~4.5Mbps bandwidth per customer - customer sensitivity to network quality & Opportunity Has established - high quality infrastructure - Large customer base Opportunities in application & value-added services

6 The Way Broadband is Being Used Today Main Internet usages (%) Mainly used for best-effort, data/control/file-oriented, store-&-forward applications seldom used for high quality, interactive/ distributive media servic (%) Where people are using Internet today Today s broadband Internet service is limited to specific locations specific time of day specific terminal specific applications Home Work School PC café etc Should overcome these barriers to generate mass application market

7 Beyond Broadband Service From simple Internet access to quality life/work services Yesterday Today Tomorrow Any-Access Access Rich Contents Browsers P2P,Game HTTP FTP Web Pages Servers Wireline HTTP WAPVoIP WAP Wireless RTP RTSP

8 Beyond Broadband Service: Features Different business From access service to end-to-end service Both best-effort & quality service From network service to solution/application services Applications: from niche market to mass revenue market Different focus Ubiquity Convergence Bandwidth Handy Beyond broadband business Quality Current broadband access business Personalization
