What RF phenomenon results from a presence of metallic I-beams, conveyor belts, chain-link fences, and metallic shelves found in a warehousing environment?
A. scattering
B. absorption
C. free path loss
D. multipath
I’m sure it must be D.
A is not correct, D is correct
Scattering happens from micro particles in the air
Metal Reflects signals and relfections can cause multipath
remember there is a way to to turn omni directional antenna into a directional antenna by placing a metal plate behind antenna
so D is correct
This is a tricky question actually. both A and D could be the answer, but with your explanation, I agree that it is D then. Thanks Anon!
I think it is A. B is smart use of A.
I mean D is smart use of A.
I agree, A is the correct answer.
