a semi deterministic propagation model based on De Jong recommendations is described. It is an extended 2D-ray tracing model for planning microcell in urban environment. It uses virtual sources, in order to model the Wave Propagation phenomena (building transmissions, tree scattering, diffraction by external corners, and wall reflections) of a base station emission that may reach even hidden buildings out of the line of sight even far beyond visible buildings, but also takes into account the channel influence in signal parameters like complex amplitude and frequency. New concepts and modifications introduced by the authors to achieve a practical implementation are also described.
