Why choose TONEX for your VSAT Training?

VSAT Training covers Very Small Aperture Terminal (VSAT) systems. VSAT is growing throughout the world as a way of establishing private satellite communications networks for large organizations that have several widely dispersed locations, or providing higher bandwidth for the individual.

Depending on bandwidth requirement (data speed and/or communications channels), VSAT systems can be relatively small and easily installed.

A VSAT is a two-way satellite ground station with a dish antenna that is smaller than 3 meters (most VSAT antennas range from 75 cm to 2.4 m).

Very Small Aperture Terminals data rates typically range from narrowband up to 18 Mbit/s.

Very Small Aperture Terminals access satellites in geosynchronous orbit to relay data from small remote earth stations (terminals) to other terminals (in mesh configurations) or master earth station hubs (in star configurations).
