x19 on Ubiquity. We use several nanos at work to shoot network over long distance to remote locations where we don't have fiber. The traffic includes everything, including phone.
I used a pair of Nanos to shoot our internet 400' down an alley to share our bandwidth. Beam went through some tree fodder and into the front gable of a house, with the target nano INSIDE the house attic. So "line of sight" can be modified somewhat. Link was reliable like a wire.
Also not mentioned - Ubquity setup is typically non-trivial. Their stuff comes out of the box needing configuration with the nanny-type setup wizard you find in other home use devices. Unifi is pretty easy and has good management. We're using Unifi mesh APs to blanket a football field. One AC-MESH threw a signal over chain link, across a college width football field and up in to a glass front press box, recording a -65 dB signal inside the pressbox, measured with a phone.
Note above - sheet metal will significantly weaken the signal, not sure of a figure. In the above notation about Unifi Mesh, when the test AP was hanging inside the "bread truck" (just what you'd think - big steel van) it cut the range by over half. Brick is good for average -10 dB signal loss. If your far target includes sheet steel facade of any sort, I'd suggest mounting a Nano outside.
If you are worried about Nanos being out in the sun and rain, note that we've had some on station for over 4 years. Outdoors, on a pole, up in the air and exposed to sun. They get quite a tan. Also, in the big hail storm back in 2014 that did over $1m damage to our campus, not a single nano took a hit. Right now I have a Rocket on a sector antenna with 4 remotes, closest about .4 mile, farthest .6 mile. If I didn't have a Wiki page on the setup, I'd forget how to log into them. Never an issue.
