Rough concrete columns in a municipal parking garage break up the Wi-Fi wave. Which RF behavior describes RF dispersing in many directions off uneven surfaces?
Select an answer to reveal the explanation.
Short Explanation
Rough concrete is like throwing a handful of gravel at a wave — energy sprays everywhere instead of one clean bounce. That spray is scattering. One shiny metal door might mirror; crumbly columns shred the wave into many weak paths.
Full Explanation
Scattering disperses RF energy in many directions when the wave interacts with rough or uneven surfaces such as coarse concrete. That differs from a predominantly specular reflection off a smooth surface. Concrete columns do not provide intentional antenna gain, nor do they change the assigned carrier frequency. Recognizing scattering helps explain fragmented multipath in parking structures.
