You have dozens of devices in what sounds like small locations across your state. I have 11k users online in North America and I would never trust Unifi for any part of my network. They have their place but enterprise is not one of them. SMB is not the same.
All parents and responses to my posts are probably right, and I'm probably wrong!
My experiences aren't wrong, of course, but it's an apples to oranges comparison. My IT MSP is only small to medium sized businesses (as I think all IT MSPs are since Enterprise level environments don't contract out it and hire their own department - this is an educated guess). We do very little Enterprise work and have no single client with more than 300 users.
However, I will defend my position and consumer grade ubiquitis on a (significant) technicality. Higher models beyond what my company sells are not cost effective. Buying higher grade waps at no less than double the price is more expensive than just running cables. If you WANT to make everyone get 200mbps wifi, you will pay for it, but that's a convenience you pay for, not a requirement. UAP-AC-Pros are perfectly capable of handing out up to 50mbps pipes to multiple endpoints without huge (or even medium) upfront capital investments, overheating or DB problems. In my opinion, just run cat6 lines. Itll be cheaper than spending thousands on Enterprise waps for only 30 people.
