With the increasing need of accuracy, deterministic propagation models have been widely adopted in site-specific wireless applications. Compared to empirical models, they are usuaIIy more accurate, but time-consuming. Several acceleration techniques have reduced the simulation time and yet the computation of typical scenarios remains complex. In this paper, a novel 3D model, namely IRLA (Intelligent Ray Launching Algorithm) is presented to predict a huge number of receiver pixels (few millions) in a large scenario (few square kilometers) within few seconds, which is beneficial to relevant academics and industries.
