The distribution of angle of arrival of multipaths in a novel three- dimensional approach is modelled. The approach followed takes into consideration a cluster of scatterers local to the mobile and models it using mixtures of Von Mises Fisher (VMF) distributions. Real MIMO experimental data was collected in a drive test campaign in Ilmenau city of Germany and was used to validate the proposed model. Results show a good match between the proposed model and the two-dimensional experimental histogram.
