Air Marshall Collisions with Friendly Wireless APs. - How to co-exist?

nClarity_2023

We deploy a large number of cellular wireless gateways as part of our IOT solution, which operates on rooftops and outdoor spaces to collect IOT data on building equipment.

We are finding that in some cases, an unknown Air Marshall is shutting down our networks using disassociation packets, causing our wireless clients to constantly disconnect / reconnect.

How can we co-exist with Air Marshalls? How do we find out who they are? I know about white-listing, but that means you need to know who is running the air marshall and contact them.

What about hidden networks? e.g. if we deploy in a hidden fashion, will the Air Marshall still detect them and shut us down?

Can anyone advise if the Air Marshall will detect hidden networks?

Yes. Also, never use a hidden network on 5 GHz. Clients will struggle as they can’t probe on a DFS channel
