Cable modem networks are labor intensive in installation and have limited throughput when the last coax section is oversubscribed. This is where Satellite comes in. Satellite can fill in pockets where other technologies can t reach. You get global coverage in a flash. There is only one network to deal with.
Quality of service is high.
Satellites have a certain unique advantage. They are unequaled for broadcast applications such as the delivery of the same information to a large group of users. A majority of the Internet applications in the future will be streaming, broad- and multicast services such as playing audio or video. For GEO satellite communications systems, the latency is at least 250 milliseconds on each path. The latency might not affect bulk data transfer and broadcast-type applications, but it will hurt highly interactive applications that require extensive handshaking between two sites.
