Terrain Partial Obstruction LOS Path Loss Model for Rural Environments

The first Fresnel zone of direct path interacts differently with various terrain profiles, resulting in different partial obstruction losses. This letter presents a new model for partial obstruction of descending terrain extracted from a large number of terrain profiles representing various terrain characteristics and base-station antenna heights. The model is simple enough to be effectively used in system-level simulations and RF predictions without excessive analysis of the underlying terrain data.
