+1..
I have couple in play now shot links of about 3 miles with 8x8
modulation getting 60+Mbs both directions.
12mile LOS would be much with good dishes

Unfortunately, the 14, 15, 16 mile links in Florida would be fairly
difficult at 11 ghz, even with 4ft dishes, which I cant load up on a
Rohn 25G tower.

i would go licensed gear from SAF (or your favorite licensed PTP vendor).
we keep all the unlicensed bands available for PMP...we use licensed
for PTP.
the difference between a wifi backhaul and a licensed backhaul is like
the difference between a Ford Focus and a Ferrari F12berlinetta. they
are both cars that drive on roads but that's about where the
similarities end. same thing with backhauls.

And, I need better consistency... at times the links do not perform as
I expect and then I get customer complaints etc. I hate that.
