Implements the Stanford University Interim (SUI) path loss model, an empirical model used to predict radio signal attenuation over various terrain types. Path loss is calculated based on distance, frequency, and antenna heights, with parameter sets defined for different environments.

The model defines three terrain categories:

• Terrain A: Highest path loss (dense urban or hilly areas)
• Terrain B: Moderate path loss (suburban or mixed environments)
• Terrain C: Lowest path loss (flat/rural areas with light vegetation)
