Introduction:

VSAT Training - Very Small Aperture Terminal Training In Depth

VSAT Training - Very Small Aperture Terminal Training is an intensive, learning experiences that cover the essential elements of your chose subject. VSAT Training is ideal for busy professionals who want to stay current in their fields but have limited time to be away from the office.

This intensive technical VSAT Training - Very Small Aperture Terminal Training 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.

VSAT technical boot camp details the technology of satellite communications, focusing on VSAT networks and how they compete with terrestrial alternatives. 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.

Customize It:

With onsite Training, courses can be scheduled on a date that is convenient for you, and because they can be scheduled at your location, you don’t incur travel costs and students won’t be away from home. Onsite classes can also be tailored to meet your needs. You might shorten a 5-day class into a 3-day class, or combine portions of several related courses into a single course, or have the instructor vary the emphasis of topics depending on your staff’s and site’s requirements.
