Training Course: Fundamentals of VSAT Systems & Protocols

Introduction

This course 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. This course provides the attendees with an in-depth background of VSAT techniques as well as a state-of-the-art update on key emerging technologies and future systems.
