DESCRIPTION OF THIS TWO-WAY DIGITAL COMPUTER TERMINAL AND THE RESULTS OF OPERATIONAL TESTING OF THE SYSTEM IN KANSAS CITY (MO), NASHVILLE (TN), WEST PALM BEACH (FL), AND THE STATE OF NEW YORK.
Abstract
THE MOBILE COMMUNICATIONS TERMINAL (MCT-10), DISCUSSED IN THIS ARTICLE IS A VISUAL DISPLAY TERMINAL WITH A KEYBOARD WHICH THE PATROL USES TO COMMUNICATE WITH THE POLICE DISPATCHER OR DIRECTLY TO THE COMPUTER. THE MCT-10 SYSTEM HAS THREE PRINCIPAL COMPONENTS - A TWO-WAY TERMINAL FOR THE PATROL CAR, A FLEXIBLE INTERFACE SYSTEM FOR THE LAW ENFORCEMENT AGENCY'S COMPUTER, AND A POWERFUL RADIO TRANSMISSION TECHNIQUE, CALLED PHASE SHIFT KEYING, TO LINK THE TWO. THIS NEW TECHNIQUE INVOLVES DIGITAL TRANSMISSION OVER TWO-WAY FM RADIOS.
