The Rayleigh scattering effect applies to 'light' signals, and the scattering of a signal when passing through a material medium, the amount of light scattered is proportional to 1/$\lambda^4$. I am curious as to why(or if) this wasn't considered when we established global communication systems through the various means of modulation. The high-frequency carrier/modulated signal used in say, FM, should visibly have a small wavelength, and since it is an EM wave too(like visible light or others) shouldn't we be concerned about its scattering as much as we are concerned about the consumed bandwidth or SNR etc. ?
I am not sure if I should be posting this in the Stack PE, I request the moderators to kindly direct me. Tag/post edits are welcome. Thank you!
