Hi, we need to install wireless in a hard environment (with explosive atmosphere) classified as ATEX zone 20 and 21. Have anyone of you deal with something like this? In Cisco website we only see the ATEX certified in the AP 1522HR, but we don't know if also the antennas have to be certified (as they are a passive element) (we don't see any certified logo in the antennas)

Any experience?

Regards!
