Cons: Limitations in the distance from the central office; compatibility problems with some central office chip sets

Pros: Always on; no distance limitations; higher availability; increasing availability of retail modems and equipment

Cons: Shared bandwidth (more subscribers in your neighborhood means lower bandwidth); security issues

Estimated subscribers in 2000: 1.97 million*
Projected subscribers in 2004: 12.2 million*
Estimated subscribers in 2000: 3.4 million

Pros: Relatively easy end-user installation; works in areas lacking a wired infrastructure; easy to deploy; easy to secure with IP-based routers and firewalls

Cons: Service and equipment can be expensive; not yet widely available

Pros: Good for those who cannot get broadband any other way

Cons: Shared bandwidth; the transmission distance (44,000 miles round-trip) means some latency; occasional weather and solar interference; unobstructed view of the southern sky required; long service waits possible

Estimated subscribers in 2000: 144,000
Projected subscribers in 2004: 1.5 million
Estimated subscribers in 2000: 75,000
Projected subscribers in 2004: 2.4 million

This is the average throughput observed by 800 testers; it represents real-world performance and takes into consideration latency, overhead, and HTTP limitations. ISP responses for eight major Web sites are represented by the red bars and all other activity by the green bars. For comparison, the average actual throughput of a 56K modem is 5 Kbps.
