A general overview of VSAT system: A popular way for availing internet in remote location

Have a stable internet connections is important in almost all business environments today. However, a lot of businesses that are based in remote locations do struggle to avail proper Broadband Solutions.  For these businesses, it is better to opt for more reliable, flexible satellite communication systems, rather than typical terrestrial networks. One of the most dependable and efficient satellite internet solutions available today is VSAT. It has become a popular choice for businesses located in third world countries and far flung regions, but requires unlimited geographic reach and efficient data transmission.

What is VSAT?

Very Small Aperture Terminal or VSAT is a two-way satellite ground station that allows for fast internet connectivity. This system comprises of a dish antenna, transceiver and a satellite router (modem). The “very small” part of the VSAT acronym refers to the physical size of a satellite dish. This size can vary from .75 to 3.8 meters. VSAT system connects to geostationary satellites that stay in the same position relative to the earth. This basically means that VSAT antennas do not need require to track moving satellites, ensuring a more reliable internet connection.

How does VSAT work?

You first need to first link your computer to an outside antenna with a transceiver to connect to the internet. This transceiver subsequently sends and receives signals to a satellite transponder in the sky. VSAT can then transmit satellite communications like video, voice and data with ease. In case of VSAT Services, the communication satellites receive signals from these satellite dishes and then retransmit them to the earth. As long as they are within the coverage area of the satellite, an unlimited number of satellite antennas can receive these retransmitted signals.

“Star topology” refers to the typical setup for VSAT networks. Several VSAT terminals tend to be spread through a particular region and controlled via a central hub station. Certain businesses may also implement a mesh topology so that just one terminal can transmit data from the satellite to all other terminals. VSAT satellite technology can be availed in varying frequencies, sizes and shapes. Its typical operating frequencies include Ku-band and C-band, and they work with star network for a private hub. These systems may also work point-to-point for a customized private hub capable of supporting many locations
