Interesting no rants yet about disabling a feature to charge less. Yet look at all the SKUs that Intel creates by disabling cores, disabling hyperthreading, disabling some of the cache, etc. It feels OK to buy an inexpensive 4 core CPU until you find out it’s a 6 core chip with 2 cores disabled. But if it’s cheaper for Intel than actually making different dies, what does it matter if the end result is the same? I think it’s human nature, we’re happier not knowing some things.

Via onboard GPS and the external puck (for added gain) or via CMM on the Ethernet side. The CSM (Connectorized Module without sync) CANNOT be used as a sync device whatsoever. As for the Force PTP, yes, it does use the GPS unit but sync is disabled in the Force PTP configuration. Hope this helps. Sakid p.s.

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?

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)
