Wi-Fi and the Problem with Radar (DFS)
Wi-Fi and the problem with RADAR is that the frequencies can overlap - they can interfere with each other. There are some solutions - let's explore DFS.
You may have seen a large radome (tallish building with a giant golf ball on top) near such facilities and it turns out that this can be operating in some of the 5GHz spectrum. The DFS process is all about detecting when a radar facility is nearby and ensuring that any Wi-Fi devices can't interfere. If you have newer APs, you'll find you can use the UNI II Extended band, which will allow some additional channels to be used - which depending on the region you're in, might help.
