Radiosity-an approach to determine the effect of rough surface scattering in mobile scenarios

An important factor in positioning the base station in a cellular communication system is the propagation pathloss as a function of the environment. Radiosity is applied to radio propagation problems showing that the influence of the rough surface is not just included by reducing the specularly reflected component since also contributions from the rest of the surface contribute to the total received power, confirming the cluster theory. Furthermore, the decay factor is determined for both indoor and rural environments and approaches the power of -2 and -2.5 respectively, having line of sight.
