Comparison of predictions from a ray tracing microcellular model with narrowband measurements [PDF]
In this paper predictions from a 3-D 'image-based' ray tracing model for microcellular environments are compared with three sets of narrowband measurements performed in a typical urban area. The comparisons illustrate that good agreement can be obtained,
