It's inverse square -- think of it as the surface area of the sphere a specific distance from the source at any given instant. Not the volume of the space between the frontier and the source.
- hyeonwho4 8y agoAlthough the free space attenuation is inverse square, interference effects can increase power attenuation for radio waves in the far field limit. If there is reflection off the ground, the power attenuation is closer to inverse quartic in the far field. https://en.m.wikipedia.org/wiki/Two-ray_ground-reflection_model https://en.m.wikipedia.org/wiki/Two-ray_ground-reflection_mo...
