A transit hub near an airport sees APs repeatedly leave DFS channels after radar events. What is the correct expert interpretation?
Select an answer to reveal the explanation.
Short Explanation
Near an airport, DFS is the AP politely leaving the room when radar knocks — that's the rules, not a broken PoE brick. Plan around non-DFS channels or accept validated DFS churn. Blaming SAE or copper misses the regulatory RF behavior.
Full Explanation
Dynamic Frequency Selection requires WLAN devices on certain 5 GHz channels to detect radar and vacate the channel per regulatory rules. Proximity to aviation radar makes DFS exits expected, not evidence of PoE or AKM failure. Channel plans should account for non-DFS inventory, CAC timing, and potential service interruption on DFS channels.
