Name	Type	Description
FreeSpacePathLoss	compound module	Implements the free space path loss model, which models signal attenuation over distance according to the Friis transmission equation. Calculates signal power loss as a function of distance, wavelength, and configurable parameters. The alpha parameter controls the path loss exponent (default 2), while the systemLoss parameter accounts for hardware inefficiencies. Provides an ideal baseline model for wireless propagation in environments with line-of-sight and no obstacles.
