WiFi mesh recommendations for a site with multiple steel porta cabins?

In a "Faraday cage" environment like a steel cabin, would you recommend wired backhaul between every unit, or can the Orbi Pro wireless backhaul punch through windows effectively enough?

Hard to say if you'll get signal through the cabins, it depends in part on whether the windows are in the line of sight.  Some window coatings are metallic, and might also block some signal.

You can test this by putting a wifi router or AP inside the cabin (it doesn't matter what model), and measure the WiFi RSSI outside on your phone.  You'd ideally want -30 to -50 dbm at the spot where you'd put the second mesh element.  I doubt you'll get that, but you will want at least -65 dbm.

Wired backhaul is a more conservative approach, as long as the distance between the cabins is less than 100m.  

Do you want wifi outside the cabins?  Or only inside?
