Internet Via Satellite
The Internet “Bucket” is Far From Full…
 Only 5% of the world’s population use the Internet
 Penetration rate in North America is only 45%
Internet Over Satellites: A Summary
 INTERNET over INTELSAT’s satellites:
-Over 80% of African countries use INTELSAT for their Internet traffic with Europe and North America
-INTELSAT carries more than 10x36 MHz of Internet traffic
Internet Delivery via Satellites: What are the Drivers?
 Rapid and easy implementation
 Network congestion bypass
 High quality
 Delivering Cost savings
 Scalable capacity
 IP multicast
 Symmetric & asymmetric configurations
Benefits of 2-way Internet via Satellite
 Deployable almost anywhere
 No phone connection required
 Low cost
 Small antenna, variety of packages
 Easy installation
 One hour process, within days of order
 High speed and performance
 Always-on connection; 20+ times faster than ISDN
Drivers Unique to Africa
 Insufficient terrestrial facilities, no cable connectivity - leading to demand for satellite solutions
 Lack of Cross-border or regional backbones
 Local Web content development increasing
 Hosts went up from 290 (1995) to over 10,000 (1998) excluding RSA; leading to a dramatic increase in demand for bandwidth
 The factors above are driving growth
 1995 South Africa had 64kbps links
 Today, 17 countries have 512kbps satellite links or more
 Kenya, Nigeria, RSA have 8 Mbps or more satellite links in service
Asymmetry
 Internet traffic is asymmetric
 Ratio of request traffic to return traffic is typically 1:5
 Host location of Internet data is predominantly in North America (75% by some estimates)
 Terrestrial networks typically offer symmetrical links; Not cost effective
