Market dynamics, architectures, solutions
Satellite Access systems use satellite links to provide “always-on” broadband connections to the Internet. A satellite access system is typically composed of the satellite and server at the service provider end, and satellite receiver, satellite modem, and analog modem at the consumer end. A Digital Video Broadcast (DVB) signal is sent from a satellite to a receiving dish at rates ranging from 6 to 33 Mbps. This receiving dish is connected to a satellite modem with DVB processing capability and processes the Select a Solution for 
data for the PC. To upload data to the Internet, a 56 Kbps dial-up modem is used since upload requests are less bandwidth intensive than download data. The server at the service provider end manages these requests. Simultaneous use of satellite technology as a Digital Video Broadcast system and an Internet access system is made possible by the spare transponder space on satellite channels. Some of the different standards are DSS (Hughes proprietary), DVB (ETS 300-421, an open standards consortium), and Primestar (ITU-R 217/11, being phased out).
