For Cambium.... we have a very remote tower that feeds several other towers.
Everything is OSPF but logically...
Tower R (the main remote tower - a 190 ft. Rohn 25G with several anti-twist
devices) is "fed" by...
Tower A - 26 miles away - UBNT 3.65ghz Rocket M5 AND a Mikrotik RB912 5
Ghz
This commercial tower (Tower A) has over 300Mbit of usable
bandwidth and feeds about 75 to 85 Mbit to Tower A
Tower B - 9 miles away - UBNT 5ghz Rocket M5
This tower (Tower B) is a 90 ft. Rohn 25G
Tower R then feeds...
Tower C - 12 miles away - Mikrotik RB912 - 5 GHz - 50 Mbit of usable
bandwidth. (Rohn 25G 120 ft.)
Tower D - 15 miles away - Mikrotik RB912 - 5 GHz - 40 Mbit of usable
bandwidth. (Rohn 25G 120 ft.)
Tower E - 17 miles away - Mikrotik RB912 - 5 GHz - 40 Mbit of usable
bandwidth. (Rohn 25G 120 ft.)
Tower F - 14 miles away - Mikrotik RB912 - 5 GHz - 40 Mbit of usable
bandwidth. (Rohn 25G 120 ft.)
To get all this to work without Sync was quite a frequency juggling act. There
are other towers in the area and towers C, D, E, F connect (chain) to each
other on the "back side" and we use a couple 3.65Ghz UBNT radios on the
backside links.
The challenge...
First of all, I need more BW to each tower, but mostly Tower C. 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.
So, what would be the best solution that Cambium can recommend other than a ton
of licensed links? Obviously, the gear I am using now is inexpensive.
The PTP110 solution ... 2ms unsynced.... can it sync, now or tomorrow?
Latency with sync?

Reading this spec sheet.

>>>LATENCY (nominal, one way) < 2 ms (PTP Mode), 6 ms (Flexible Frame
>>>Mode) , 17 ms (GPS Sync Mode)
