A warehouse channel shows a steady high noise floor, and a spectrum check shows constant energy from a wireless camera. No beacons come from that camera. What is it?
Select an answer to reveal the explanation.
Short Explanation
The camera is making noise, not introducing itself. You have a non-Wi-Fi interferer on that channel. A rogue would be sending beacons, and this camera is not.
Full Explanation
A rogue access point is a Wi-Fi transmitter, and it sends beacons. This camera puts constant energy on the channel, raises the noise floor, and sends no beacons, so it is a non-Wi-Fi interferer. Constant energy does not mean the device must be beaconing an SSID. A coverage hole is a weak corporate signal, not a camera filling the channel. DFS is a reaction to radar, typically on certain 5 GHz channels. A camera's continuous energy is not a radar signature just because it occupies a channel. A wireless camera floods a channel with energy and sends no beacons. That is a non-Wi-Fi interferer, not a rogue access point. Check one live client after the change and leave the rest of the floor alone until that client matches the result you expected. Read the live counters after you retest. Exam caveat: if a later capture shows beacons from that device, reclassify it. The classifying fact here is energy without beacons. Operational check: note the channel, move the corporate radio off it, and confirm the noise floor on the new channel is quiet.
