TwoRayInterference¶

Package: inet.physicallayer.wireless.common.pathloss

compound module TwoRayInterference

Path loss model that accounts for interference between direct and ground-reflected signal paths. Considers phase differences, polarization effects (horizontal or vertical), and ground permittivity to accurately model constructive and destructive interference patterns, yielding a more accurate approximation than TwoRayGroundReflection even on short distances.

Based on research by Sommer and Dressler, this model is particularly suitable for vehicular network simulations where ground reflections significantly impact signal propagation.
