• Abstract:
  The Indiana Department of Transportation(INDOT) is beginning to make widespread use of wireless communications for interconnect of traffic signals in coordinated systems. The radiotechnology adopted for use in these systems is based upon spread spectrum modulation (either frequency hopped or direct sequence) and the frequency band is typically the 900 MHz unlicensed ISM band. There are a number of manufacturers of applicable radios. The main goal of this project was to support INDOT's systems engineering by designing and building a test bed radio network on the Purdue campus, which could be used to test various vendor's radios. The radio network has been constructed and tested. The network involves three nodes terminating in the Wireless Communications Research Laboratory, one node terminating in the Harold L. Michael Traffic Operations Laboratory, and one node terminating in a traffic signal cabinet located at the intersection of Northwestern and Stadium Avenue in West Lafayette. In addition, portable nodes were constructed for testing at other locations or outside of West Lafayette. The network was used in a number of tests in West Lafayette and Indianapolis.
