Abstract
The role and the importance of diffuse scattering in urban radio propagation is evaluated using a new, simple analytical scattering model and a ray tracing tool. The scattering model is arranged so that the main parameters, having a precise physical meaning, can be easily tuned using classical measurement or simulation results reported in the literature. A basic urban topology has been considered and the impact of diffuse scattering on narrowband as well as wideband propagation parameters has been investigated. Although the scattering parameters have been underestimated (with respect to literature data) in order for the evaluation to be more conservative, the scattering contribution has shown to be very important for both received power and channel dispersion in a variety of cases
