Professor Santiago developed the Educomm System during his tour at the
United States Air Force Academy
(1984-89) to provide a systems perspective on communications. This
presentation was recorded during his visit to the USAF Academy in 1994 and he was able to get
one Educomm back to his home base at Eglin Air Force Base when he was
station there from 1991-96. He used the Educomm to demonstrate to his people that the
key communications concepts can be applied to laser radar technology (or
ladar -- the mother of all acronyms).
Professor Santiago visit to the Academy was to remind folks why he developed Educomm
and show the numerous ways how important communications concepts can be
demonstrated. The idea of Educomm came from Dr
Wickert of the
University of Colorado, Colorado Springs in a campus to share ideas.
Professor Santiago was with two Academy instructors and long time friends
from the EE Department.
