A festival temporary WLAN plan places every 5 GHz AP only on DFS channels to maximize count. Mid-event radar detections force channel moves and capacity collapses. What risk should have been highlighted in the design review?
Select an answer to reveal the explanation.
Short Explanation
DFS channels are extra lanes that close when weather radar—or anything that looks like it—shows up. If the whole festival plan lives only there, one detection sends APs packing. Keep some non-DFS capacity so the show survives radar days.
Full Explanation
DFS requires channel availability check and vacating when radar is detected, which can drop capacity and force disruptive moves during events. Designs that exclusively use DFS maximize channel count on paper but concentrate operational risk. Balanced plans retain sufficient non-DFS capacity for critical coverage. MCS myths and 2.4 GHz radar claims are incorrect.
