A designer applies a free-space path loss estimate from a rooftop PTP worksheet to predict coverage inside a multi-floor atrium with glass and walkways. What is the expert critique?
Select an answer to reveal the explanation.
Short Explanation
Free-space math is for open sky, not a glass atrium full of floors and railings — that's a different movie. Use indoor models and measurements. Copy-pasting rooftop FSPL into city hall is how designs go sideways.
Full Explanation
Free-space path loss models assume an unobstructed free-space path and do not capture indoor multipath, floor attenuation, or complex atrium geometry. Expert indoor design uses appropriate indoor models, predictive tools with correct materials, and measured validation rather than rooftop FSPL worksheets alone.
