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. http://www.cambiumnetworks.com/files/PRODUCTS/ePMP/FORCE/Force%20110%20PTP_Oct2014.pdf >>>LATENCY (nominal, one way) < 2 ms (PTP Mode), 6 ms (Flexible Frame >>>Mode) , 17 ms (GPS Sync Mode)
