Abstract :
Toward the goal of achieving robust ray tracing based channel models this paper compares simulation results using a 3D ray-tracing tool [F. Aryanfar and S. Safavi-Naeini, 1998] vs. field measurements in different environments. The tool has been validated for many outdoor and indoor scenes at different frequency bands and is capable of accurate prediction of wireless channel parameters. To test model robustness, we also examine the sensitivity of the predicted results on inputs such as angular resolution, material properties and detail of geometry.
