Name	Type	Description
TwoRayGroundReflection	compound module	Implements the two-ray ground reflection path loss model for wireless communications. This model accounts for both the direct line-of-sight path and a ground-reflected path between transmitter and receiver. For distances less than the crossover distance, it uses the free space model; beyond that, it applies the two-ray formula which considers transmitter and receiver heights above ground. (The crossover distance is computed from the heights and the frequency.) This model provides more accurate predictions than free space models for medium to long distances in environments with significant ground reflections.
