We plan to enable GPS Sync for a single “SM” connected (i.e. a PTP link) in a software update coming in the near future. It will be a software update to any Force 110 PTP radios that have been purchased.

So come on Cambium, don't make me buy AirFiber 5X's. On 3/11/2015 7:19 PM, Mathew Howard wrote: Yes! If the force110 PTP will get a PTP-only sync ability at some point, I'm going to start using them everywhere even if I don't actually sync. as they are now, I'm not sure it's worth spending the extra money over just using a standard force110.

I can understand they don't want us buying the PTP radio at half the price and someone figuring out how to hack it into an AP. For PTP links, I would spend the extra $ for the PTP radio whether I need the sync or not, may need it in the future, so why not put it up now. And I'm talking both ends, you never know if you have to swap masters for timing. On 3/11/2015 5:13 PM, Mathew Howard wrote: I know... I was told they were looking into doing just that.

I'd like to see it limited to being only a PTP, just allow the sync.

PTP being possibly better if you have a large scale of synced backhauls I suppose.

PTP mode is TDD based and does support GPS Sync. The 2.5 msec frame also will support GPS Sync.

Is there a way to do it WITH GPS sync to allow frequency reuse for PTP yet? Running out of 5ghz spectrum.
