It enables devices to be allocated bandwidth on a Committed Information Rate (CIR) and also allows for rapid applications (Invsat.com). In a frame relay network, a geosynchronous satellite (GEOs) is used as the link between frame relay switches, or routers, and the other devices on the network (Shelly).
For three decades, satellite communications have been used for public switched telephone network (PSTN) and video broadcasting applications.
However, with daily technology advancements made in society and the requirement for global data connectivity, satellites are increasingly being used to provide data communication links at all data rates ranging from 64 Kbps to 155 Mbps (Buchsbaum).
Point-to-point links are achieved when only one receiver accepts the broadcast carrier.
Broadcasting is usually unidirectional while multicasting can be both unidirectional and bi-directional.
