Hi Chris, We have a wide variety of Manufacturing customers that leverage Meraki in harsh environments including steel foundry, casting, and parts manufacturing facilities. In most cases, as @PhilipDAth mentions, the MR84 (4x4:4) would be recommended for harsher/RF challenging environments or outdoors as well as the MR74 (2x2:2). MR84: https://meraki.cisco.com/products/wireless/mr84 MR74: https://meraki.cisco.com/products/wireless/mr74 As an additional option, we now have external antenna models of both the MR42 and MR53 that have been very successful in challenging Manufacturing and Warehouse RF environments that don't have extreme environmental requirements. MR53E: https://meraki.cisco.com/products/wireless/mr53e MR42E: https://meraki.cisco.com/products/wireless/mr42e As @GB4Meraki mentioned, we have many partners who can further reinforce the MR's for extreme environments. Here are links to a few we leverage in Manufacturing and Chemical Processing...
