Ive used the nanobeam 5ghz and get like 400mbps up and down between 2 buildings about 2000' apart clear line of sight in a rural area. Now, I have the same devices in a metro area, about 100' from each other and they are extremely problematic, and I am having it hardwired as I type this.
When I say problematic, the AP disconnects from the other one, and if I don't have it programmed to autoreboot, its dead in the water. I recently had a pair totally drop offline to where I could not reach either.
Makes me rethink doing wireless.
