VSAT Training | Very Small aperture Terminal Training

VSAT Training, Very Small aperture Terminal (VSAT) Training by TONEX since 1998.

VSAT Training is an intensive, learning experiences that cover the essential elements of learning VSAT, ideal for busy technical and non-technical professionals who want to stay current in the VSAT field.

Benefits of VSAT Training by TONEX

This intensive technical VSAT Training provides the attendees with an in-depth background of VSAT techniques, operations, issues, optimizations, applications as well as a state of the art update on key emerging technologies and future systems.  VSAT are used by a number of customers including enterprises, governments and other remote users.

The fundamentals of Constituent parts of a VSAT configuration, planning, network architecture, orbits, link budget, coverage, ground equipment hardware, installation, operation, and maintenance are covered.

VSAT (Very Small Aperture Terminal) is based on the satellite technology enabling real-time broadband communications in areas where traditional terrestrial and communication infrastructure is unavailable or unreliable. Remote users can use VSAT systems (using satellites, hubs and remote site equipment) for voice, data, video and fax capabilities including:

• Telephone calls
• Access the Internet operating in isolated or harsh environments
• Virtual Private Networks (VPN)
• Video 
• Other business applications

Very Small Aperture Terminal (VSAT) is growing throughout the world as a way of establishing private satellite communications networks for organizations, schools, remote industries 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).VSAT data rates typically range from narrowband up to 18 Mbit/s.

VSAT 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).
