The Bell 101 Modem - The Very First Commercial Modem

In 1958, AT&T Laboratories released the Bell 101 modem, which was developed by Bell Labs. Like so many communications technologies, new developments in computer data networking often came from a demand that originated in the military. In this respect, the Bell 101 modem was no different. The Bell 101 was originally used in the United States as part of the SAGE (Semi-Automatic Ground Environment) national air defense system. SAGE was developed in order to produce one unified image of the airspace over a wide area of the country at any given time. This information was used by NORAD (North American Aerospace Defense Command) in order to track real-time inbound airborne threats to the United States. In order to perform this task efficiently, the system needed to be able to coordinate large computer networks at SAGE director centers, scattered across the country, which were in turn connected to strategically positioned air-defense terminals at various airbases, radar sites, and command-...

Lincoln Experimental Satellite LES-1

The LES-1 Communications Satellite (including booster) Part One - An Experimental Satellite On 02.11.65, an experimental satellite, designed and built in a laboratory created by the Massachusetts Institute of Technology, working closely with the United States Air Force and the Department of Defense, was launched from Cape Canaveral in Florida . Only two yeddars later, this very same satellite would be abandoned and unceremoniously take its' place in the skies above Earth as just another piece of orbiting space junk. Forty six years later, an amateur radio operator in Great Britain, carefully rotating the dials of his ham radio receiver, heard what he thought was a faint but distinct radio transmission, rhythmically emanating from somewhere above the earth. Detailed research into the signal's origin made it clear the transmission was coming from a satellite which had been launched into space on 02.11.65; it was the very same satellite which had been g...
