Coverage behind a hill of earth fill near a water-treatment plant is dead. Staff debate reflection versus absorption as the main reason soil blocks the link. Which conclusion fits technician RF basics?
Select an answer to reveal the explanation.
Short Explanation
Dirt hills are sponges, not bathroom mirrors. Dense soil soaks up and blocks the wave, so behind the hill goes quiet. Smooth metal might bounce you a surprise path; a mound of earth usually just eats the link.
Full Explanation
Dense earth and soil are strong absorbers and blockers of WLAN RF compared with smooth conductive surfaces that may produce useful reflections. Expecting a reliable reflected path behind a dirt hill misunderstands typical absorption-dominated behavior. Soil does not retune carrier frequency or redefine PoE electrical delivery. Site obstacles of this type inform install-from-design constraints rather than CWNA-level redesign exercises.
