Satellite Services Satellite Applications and Uses Why Satellite


A quick look at two protocols for transferring data.

Satellite communications networks, like all digital telecommunications networks, employ prescribed procedures for transferring data. These are referred to as data communications protocols, or simply, protocols.

In the past ten years, satellite networks have embraced standardized protocols, allowing earth stations and user terminals to easily interface with the terrestrial world. Also supporting the same family of protocols are common user devices like PCs, video displays and cell phones.

Kinds of Protocols
  • MPEG, the dominant standard for TV encoding and transmission.
  • IP, Internet Protocol, an entire family of data communication protocols, popularized for email and Web browsing.
  • Proprietary protocols used in enterprise networks and by the government are supported by satellite links. Being replaced as organizations move applications to IP, they include:
    • Asynchronous Transfer Mode (ATM).
    • Frame Relay.
    • X.25.
