Wi-Fi near a glass curtain wall at city hall behaves oddly, with coverage appearing in unexpected directions. Which RF behavior best matches RF bouncing off that smooth surface?
Select an answer to reveal the explanation.
Short Explanation
Smooth glass can act like a mirror for RF — the wave hits and ricochets. That bounce is reflection, and it is why a client around the corner might hear the AP while someone in the 'obvious' spot sees weird fades. Mirrors redirect; they do not eat the whole meal like heavy absorption would.
Full Explanation
Reflection occurs when an RF wave encounters a surface and bounces, potentially sending energy into unexpected coverage areas and contributing to multipath. Smooth surfaces such as glass curtain walls are classic reflection candidates. Absorption removes energy into materials, FSPL is distance spreading in free space, and antenna gain is pattern focusing — none of those is the primary match for bounce-off-glass behavior described here.
