A versatile ray tracing model for microcellular planning

Describes a microcellular model, based on ray tracing techniques, which has been devised in order to address some of the considerations that are unique to microcells. Ray tracing is a stationary phase technique which relies on the quasi-optical properties of radio waves in regions where any obstacles are large in terms of a wavelength. The model described is a very versatile implementation, which can be used to study both indoor and outdoor propagation phenomena for a number of different types of service. In its fullest form it requires input data of a sophistication that is not commercially available. However, this has been carried out intentionally so that the model can be used to assess the implications in terms of accuracy of using commercial building databases
