Free space propagation model
Model the behavior of electromagnetic radiation from a point of transmission as it
travels through free space by using a
FreeSpace object. Free space
propagation models have no enforced frequency range, assume line-of-sight (LOS) conditions,
and disregard terrain, the curvature of the Earth, and other obstacles.
FreeSpace objects have no properties.
