A courthouse installs patch antennas aimed into drywall that contains foil-backed insulation. Coverage that looked acceptable in a soft-office predictive model collapses. What should the expert conclude?
Select an answer to reveal the explanation.
Short Explanation
Foil-backed drywall is like aiming a flashlight into a mirror wrapped in tin foil — a lot of energy never gets where the soft-office drawing said it would. Measure the real loss and rethink aim or placement. Directional patches don't get a free pass through metalized walls.
Full Explanation
Metallic and foil-backed building materials introduce substantial attenuation and reflection that office-default predictive models often understate. Directional patches aimed into such materials can worsen coverage relative to a clear path. Expert remediation revises material assumptions, measures loss, and adjusts placement, aiming, or AP density accordingly.
