We are a hybrid of mesh, p2p and point to multi-point (sector antennas). Whatever is most appropriate to give the best connection for reasonable price.
Considering the 5100 to 5850 MHz band noise floor in metro NYC, it's a minor miracle that outdoor, roof mounted, PtMP 802.11ac based systems work at all. (Or Cambium PMP450i in the same bands, etc).
Yes the noise floor is bad, but we get about a 2 mile range which covers a huge amount of people in Manhattan. The Ubiquiti sector antennas use TDMA so it is not standard 802.11ac.
That's a LiteBeam Gen1 installed in the east village on 5th St connected to 375 Pearl St downtown. The gen1 actually has a stronger signal than the gen2, so this is a bit better than our usual connection.
