Performance evaluation of indoor geolocation systems using PROPSim hardware and ray tracing software

In this paper we present a real-time channel simulation environment for performance evaluation of the indoor geolocation systems using RSS. The EKAHAU positioning software is used as the test positioning system for performance evaluation. The core of the testbed hardware is the PROPSim real-time channel simulator originally developed for real time performance evaluation of wireless communication modems. We interface the hardware to 2D ray tracing software to make it suitable for simulation of the indoor location identification. This paper provides implementation details of this testbed and presents the preliminary results of our performance evaluation.
