• Abstract:
  This purpose of this project was the design and construction of a testbed network for experimentation with spread spectrum communications in the 900 and 2400 MHz band. The current network consists of five fixed nodes and two portable nodes. Of the fixed nodes, three are located in the Purdue MSEE building, one is located in the Harold L. Michael Traffic Operations Laboratory, and one is located in the experimental traffic signal cabinet at the intersection of Stadium and Northwestern Avenues in West Lafayette. The testbed has been used to evaluate spread spectrum radio technologies from vendors Microwave Data Systems, GINA, and EnCom, as regards radio performance as a function of link distance and with varying levels of interference. The project has produced software that can be used to test any radio presenting a standard RS-232 interface to customer equipment. The testbed can also be interfaced with wireless channel emulator equipment located in the Wireless Communications Research Laboratory in order to test radio performance in multipath and fading environments.
