VSAT is the truncated form of
very small aperture terminal. It can be defined as a satellite system of
communication that helps the home users and the business users. Those who will
use this VSAT would require a box that will interface between the user’s
computer and an antenna outside with a transceiver. This transceiver does the
function of receiving or sending a signal to a satellite transponder in the
sky. This satellite obtains and directs signals from a location in earth that
acts as a center for the arrangement. Each user is connected with the centre
through the satellite. The main function of VSAT is handling data, video
signals and voice. VSAT internet in
Africa is used by domestic people as well as private companies. VSAT
proposes a number of gains over terrestrial substitutes.
Satellite Internet in Africa has been booming in recent times.
Satellite internet has certain advantages which make it popular:
·
Satellite internet gives a global exposure. This
is the most important plus point of satellite internet. A single satellite has
the strength to cover a large distance. It can be as large as covering ocean
·
This coverage of the wide range gives speedy
internet.
·
With the help of this satellite internet remote
places can be located and connected.
·
Due to topography of earth a long network on
terrestrial land cannot be erected, with the help of this satellite we can
access internet.
·
Places like oceans cannot be connected easily
with the terrestrial connection. With the help of this satellite connection we
can connect to any part of the world.
·
The very important thing about this satellite
connection is that the connection is speedy and good.
·
Other than terrestrial connection which is quite
costly this is satellite connection is less costly and stands the test of time.
·
The location is independent and can be used
anywhere.
·
A connection by the satellite can be easily
installed and uninstalled.
C band in Africa is still working
well because many people still listen to radio. With the help of this radio
transmission can work better.
The internet service which is
provided helps us a lot. But it has certain disadvantages:
·
There is a lot of wrong information in the
internet. This leads us to a wrong place.
·
People wait in the internet to make prey of
innocent people.
·
People are getting attracted to the internet and
hence causing a problem to daily life.
Thus internet facilities are
improving and we should use it intelligently.
