In a reflective city-hall lobby, clients show rapidly fluctuating SNR and MCS even when they remain near the same AP. Which RF explanation best accounts for that pattern versus simple distance-based path loss?
Select an answer to reveal the explanation.
Short Explanation
Marble and glass bounce RF around like mirrors in a funhouse — one step left and the echoes stack or cancel, so SNR jitters even when you didn't walk far. That's multipath, not 'you got farther from the AP' path loss. Wrong country codes and DFS chatter aren't the lobby story here.
Full Explanation
Reflective indoor materials create multiple propagation paths whose relative phases change with small movements or environmental shifts, producing multipath fading and variable SNR/MCS. Simple distance-based path loss predicts a comparatively steady decline with range and does not explain rapid fluctuations at a fixed location. Incorrect regulatory domains or DFS events are separate issues and are not the primary mechanism for continuous lobby multipath behavior.
