The critical role of communications and networking in the defense community has been widely recognized. The field is both broad and dynamic; while progress proceeds at a phenomenal pace, new issues and problems arise almost as fast. The underlying principles, however, change either slowly or not at all. A conceptual understanding of these principles can help those who work in all aspects of the field see the forest through the ever-changing trees. The course presents an introduction to the technical concepts that underlie the field: analog and digital communications, packet and circuit switching, voice and data networks, and the physics of radio, terrestrial, and satellite links.
This course is intended to provide an overview of the key principles of communications and networking theory, using operational and developmental military communications systems to illustrate these principles. This is not an instruction course on how to design or operate specific systems, although it can help all technical professionals understand the nuances of their systems better. Rather, the objective is to provide a mixed technical and non-technical audience with a conceptually rigorous technical foundation. It deliberately covers a very wide array of topics, based on the view that in the future all forms of military communications and networking will be tied more closely together, and thus a broader understanding will be of use to all. If successful, this course will further allow the graduates to converse more intelligently with subject-matter experts, and pave the way for further learning in more specific areas. While equations are kept to a minimum, the concepts presented are rigorous.
WHO SHOULD ATTEND
Those who have responsibilities for planning, acquiring, managing, monitoring, operating, and/or regulating communications or networking programs or systems in a military-oriented environment. The course is specifically intended for those who do not have an extensive formal background in the principles of communications but find themselves in a position where such a background would prove useful. It should also be of interest to engineers trained in other areas, and communications specialists seeking to review and expand their knowledge of the theory and practice of military communications.

Dr. Lawrence N. Goeller
Larry Goeller is a civilian working for the Office of the Secretary of Defense, in the office of Programs Analysis and Evaluation (OSD/PA&E), as an analyst for the Cost Analysis Improvement Group (CAIG). Prior to joining the government in 2004, he worked as a contractor for ASD/NII’s Communications Directorate, and before that as an analyst for the Air Staff in the area of military satellite communications. He obtained his doctorate in physics from Rice University in 1986.
