Abstract

The objective of this project was to design a radio architecture using the ITS spectral allocations in the 220-222 MHz Land Mobile band which provides a multi-mode operation optimized for point-to-point, mobile, and multiple access communications. A radio performance goal was to achieve greater than 3 bits/second/Hz transmission efficiency for mobile applications, and greater than a 5 bits/second/Hz transmission efficiency for point-to-point applications. An additional important goal of this project was to explore potential ITS applications of the modem technology particularly as applied to an application in sensor telemetry concentration. The fixed point modem will be deployed for remote surveillance camera control as a part of the Borman Expressway Advanced Traffic Management System in northern Indiana. In addition, a version of this communications architecture is being consider as a product for ITS applications by Welkin Systems of San Diego, CA.
