Characterizing Indoor Wireless Channels Via Ray Tracing, and Validation Via Measurements

The authors investigate the reliability of radio channel simulators in capturing the important properties of radio channels throughout a well-specified environment. Indoor environments for which the geometric layout and material properties of surfaces are known lend themselves to such site-specific simulation. Their aim is to assess the performance of this approach by comparing its predictions with measurements in a specific environment. The measurements are made on 18 paths in the ORBIT Laboratory of Rutgers University's WINLAB; and the simulator they use is the WiSE ray-tracing tool developed by Bell Labs.
