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)
