VSAT Network And Terminal: A General Overview

Byintersat

VSAT (Very Small Aperture Terminal) comprises of a terminal with very small dimensions that are able to offer bi-directional communication connectivity. This technology offers value added satellite connectivity for transporting data for varying Internet/Intranet applications, Video and Voice over IP, as well as general public or private networks. One can easily contact a good VSAT Engineer in Africa to avail the benefits of this system.

Owing to its rapid deployment, low costs of set up and operations and high flexibility, VSAT technology is being used in the deployment of networks across the world for private, public/governmental, and corporate applications. It is especially popular in regions of Africa where installation of typical terrestrial internet network is not that feasible. 

What are VSAT Terminals?

VSAT Terminals are also known as “private earth stations” and tends to be used primarily for business. However, many use them for personal purposes as well. The “very small” part of the acronym of VSAT terminals refers to the antenna reflector. Such terminals are relatively simple, and comprise of two primary components: The Outdoor and Indoor units. The outdoor unit encompasses of everything that one may see outside the building where the terminal is located. This equipment allows the terminal to transmit and receive signals to and from the satellite. Details of companies offering such VSAT Equipment in Africa can easily be found on the web.  The outdoor unit of VSAT terminals essentially includes:

  • The reflector
  • The feed
  • The Block Upconverter (BUC)
  • The Low Noise Block Downconverter (LNB)

VSAT technology is used in many sectors where internet is needed for crucial tasks and a highly reliable communication system is prioritized. This technology has been in the market for more than two decades with millions of sites in operation worldwide. Such factors make VSAT technology extremely dependable and “beyond tested.”  The networks based on VSAT technology are of two main areas, which includes dedicated services and the shared ones.  The shared ones generally allow multiple remote stations to share the same network in time division. Such dedicated services tend to communicate within each other without the need of a hub and on single carrier per channel. VSAT Internet in Africa is commonly used by businesses that want to have a private communications infrastructure that they have complete control over, without having to rely on existing infrastructure controlled by other parties.
