Course Description

Satellite data networks have become an important tool of corporations, government agencies as well as consumers needing remote access to the Internet. In this intermediate level, one-day course the instructor reviews the design and use of such networks, which employ inexpensive very small aperture terminals (VSATs).  The instructor will provide up-to-date information and methodologies to employ communications satellites specifically for data communications and the Internet. The focus is unique because it combines theory and practice, addressing currently available technology solutions as well as the foundations needed to understand them.

Who Should Attend

Communications engineers and networking specialists who wish to understand how communications satellites are employed to provide data communications services, particularly with TCP/IP-based very small aperture terminals (VSATs). A background in satellite communications or radio frequency systems is desirable but not essential. This course will apply to any commercial or government organization that currently employs satellite communications for data applications, or to those considering how to do so.


NEW!  Satellite Data Communications and VSAT Networks

Bruce R. Elbert

BEE, MSEE, MBA, President, Application Technology Strategy, LLC

Bruce R. Elbert is president of his own satellite technology consulting firm, Application Technology Strategy, L.L.C., Austin, Texas; and retired Adjunct Professor (ret), College of Engineering, University of Wisconsin, Madison. Mr. Elbert is a recognized radio engineer and satellite communications expert, and has been involved in the satellite and telecommunications industries for over 40 years. His consulting practice has assisted major organizations, both public and private, in the selection of the best space and ground resources, and the optimization of elements of the system at the user and provider ends. During 25 years with Hughes Electronics (in divisions now part of Boeing Satellite Systems, Intelsat and DIRECTV), he directed communications engineering of several major satellite projects, including Palapa A, Indonesia's original satellite system; the Galaxy follow-on system; direct-to-home-satellite broadcasting satellites at Ku and Ka bands, and the development of the first GEO mobile satellite system capable of serving handheld user terminals. Mr. Elbert also worked as a communications engineer for the INTELSAT system, contributing to the early development of Ka-band satellite-switched multi-beam systems and mobile satellite service to ships and aircraft. He was a radio officer in the U.S. Army and taught microwave and VHF radio at the Signal School. He has written eight books on telecommunications and IT.

Learning Objectives

  1. Understand how communications satellites are applied to two-way data communications
  2. Be able to configure a satellite data network to provide Internet-based services
  3. Identify the strengths and weaknesses of satellite data links as compared to land-based fixed and wireless data communications
