It's for the lower price point..

The 110 PTP unit has sync on board...disabled...expect that's to keep us from 
buying that unit and swapping the radios for a connectorized unit without sync.

I expect that, like the connectorized radio without sync, that you can take 
sync from a different source, like a CMM4.

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?

Hi,

Please allow me to clarify.

The Force 110 uses the Connectorized UnSync'd unit with the two 10/100 FE ports.

The Force 110 PTP uses the Connectorized GPS Sync'd unit with the
single GigE port that supports 802.3af PoE in addition to proprietary PoE. GPS 
capabilities will be disabled (but the radio can still use the on board GPS 
chip to track satellites and provide coordinates).

The 2ms latency is achieved purely through software changes in Release 2.4 and 
will apply to both products.

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)
