An overview of how VSAT system works
Very Small Aperture Terminal or VSAT involves a two-way satellite ground station that facilitates the
communication of data, video and voice signals. VSAT Internet in Africa is especially popular as this system
is able to deliver a smooth internet connection to areas where installing a terrestrial network is not
feasible. A lot of businesses and on-the-move professionals use this technology to enjoy smooth internet
connectivity, no matter whether they are. Right from education and banking to airlines and defense, you
may find the application of VSAT in many sectors.
VSAT system majorly comprises of two parts, a transceiver and an indoor device. VSAT users require a box
to read between the computer of the users, as well as an outdoor antenna that has a transceiver.
Transceiver tends to be used for sending and receiving signals to and from a satellite transponder via an
earth-based station that is known as ‘hub’. This hub is interconnected with the satellite. Every transmission
goes to the hub station first, which then retransmits the signals via the satellite reaching the VSAT of the
end users. You can always contact a good VSAT Engineer in Africa to deploy this system at your property.
VSAT technology comes with a lot of benefits. This system requires low transmission power and is relatively
affordable. Its construction cycle involves two simple steps, first is the installation of the necessary devices
at both ends of communications and then proper assembly of the equipment. The longer the distance, the
better would be the VSAT communication. Moreover, VSAT communications remain unaffected by location
or climate that can be slightly interrupted by the ground. VSAT is a pretty flexible technology, and is easy to
maintain and expand. Details of VSAT Equipment in Africa can be found online.
