Urban channel propagation modeling using the shooting and bouncing ray technique

With the increased demand for wireless technology, there is a growing need for accurate propagation channel models in urban environments. In this work, we carry out a study to characterize the urban propagation channel using the shooting and bouncing ray (SBR) technique. Simulation data are generated using a CAD model of the downtown area of Austin, Texas, and an SBR-based simulation code BATCH (Lee et al. 1994). Propagation characteristics from the simulation data are examined. The quantitative behaviors of both the slow and fast fade characteristics are extracted and compared with existing models.
