I don’t think it’s realistic to use a 40 MHz channel in the 3.65 band. If nothing else, the requirement to coordinate with other users. But also CBRS will be based around 10 MHz channels.
If PTP450 does accept timing port sync, that takes away my demerit against it.

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).

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.

They sell much less and in 5GHz there are more competitors. 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. > -----Ursprüngliche Nachricht----- > Von: Af [mailto:[email protected] <mailto:[email protected]> ] Im > Auftrag von Ken Hohhof > Gesendet: Montag, 21.
