ATEX compliant WiFi AP- Explosive Atmospheres

[bruce_richards1]

Hi,

I'm looking for a way to put WiFi into a factory area that requires special consideration for explosive atmospheres. The official spec I have to comply with is ATEX

I have found these enclosures but they need APs with external antennas

Does anyone have any ideas. We are running Ruckus everywhere else so I'd like to keep using Ruckus for this as well. 

Regards
