If I remember right, PTP450 does support sync, just not sync over
power (so you have to use the timing port), but AF-3x does have a
pretty significant speed advantage, since they can use 40mhz
channels and the PTP450 is limited to 20mhz (if I'm remembering right).

Good point, I forgot the 3.65 band allows up to 1W/MHz EIRP, so
maybe the conducted xmt power is higher than the 2 and 5 GHz
variants.
Oh, and I was looking at AF3x vs PTP450 3.65 connectorized
today, and was surprised to see that Cambium was actually
cheaper. Not quite apples-to-apples since if I remember right
PTP450 doesn’t support GPS sync? And AFx includes the GPS antenna.

It may be amplifiers are the reason for the 3.65SM heatsink and
a contributor to the higher pricing. There's a variety of COTS
high-power 2ghz and 5ghz 256-QAM-capable amplifier ICs that I've
seen inside various WISP products, it could be there is nothing
easily available for 3.65 so that is a cause of the additional
hardware/cooling and partially cost.

I dont believe UBNT/Cambium does something LTE Based. This
SIM-Stuff and complicated infrastructure would hinder low
cost. Wasn't there any licensing the vendor has to pay for
patents? UBNT want to target their airmax price range.
