Network Systems and Examples
Satellite communication networks have evolved from broadcast systems, beam switched transponder systems, to IP packet forwarding, onboard processing and switching systems. The broadcast architecture of most commercial satellites yields bandwidths of 1 to 2 GHz or less. The new applications demand an effective bandwidth increase by an order of magnitude within the next few years. The mass of satellites has been growing at the rate of 8% per year and communication payloads have been getting more efficient capacity compounded over 35 years, to well over two thousand percent . The future satellite system designs employ multiple spot beams achieving maximum frequency reuse. Satellite systems can become the imbedded infrastructure in regions with less developed communication infrastructure and complement the Internet service over other technologies such as cable, DSL, fiber, and wireless. It is expected that the market for Content Delivery Distribution via satellite network will grow up to $4 billion by 2006 .
