MICROWAVE TRANSMITTERS WERE USED TO LINK 11 INSTITUTIONS OF HIGHER LEARNING IN THE CENTRAL TEXAS AREA. THIS DEMONSTRATION WAS PLANNED AS A PILOT PROGRAM FOR THE USE OF MICROWAVE CHANNELS TO ACHIEVE A SINGLE CLOSED-CIRCUIT SYSTEM AMONG A NUMBER OF INSTITUTIONS. THE OBJECTIVES WERE (1) TO DEMONSTRATE THE FEASIBILITY, BOTH ECONOMIC AND PROGRAMMATIC, OF SUCH A SYSTEM, (2) TO MAKE IT A VIABLE, PERMANENT OPERATION, (3) TO EXPLORE THE PROBLEMS AND SOLUTIONS WHICH WOULD EMERGE IN ITS ESTABLISHMENT, AND (4) TO PROVIDE A PILOT PROJECT FOR SIMILAR DEVELOPMENTS THROUGHOUT THE NATION.
