Abstract :
A number of three-dimensional (3-D) direction-of-arrival measurements in a small campus environment at 1845 MHz are described. The impulse responses and the power have been measured using an 80-MHz wide-band receiver applying correlation techniques. These measurements are compared with theoretical predictions made with a site-specific ray-based propagation predictor tool to determine the coherently reflected part of the signal. Furthermore, radiosity is applied as a model to determine the power scattered by the surfaces
