The model was validated and adjusted using data obtained from measurement campaigns in the millimeter-wave band in different locations. The simulation uses deterministic methods to predict the received power, XPD (depolarization), RMS delay spread and mean delay in a channel with a high density of scatterers (trees, buildings, and poles). Simulated signals were transmitted in the vertical and horizontal polarizations considering the non-specular reflection caused by rough surfaces and the effect of the height variation of the transmitter in outdoor channels.
