Remember something like 8 years ago when the FCC retroactively required DFS in U-NII-2 and some manufacturers just dropped support of that band instead of getting DFS? (Cough, cough, Trango) I wonder if the whole industry is abandoning DFS. I see that tri-band AC routers now come set by default to use U-NII-1 and U-NII-3, and why not, given the higher xmt power and no DFS. I know that I’m reluctant to use DFS bands outdoors unless it’s the middle of nowhere, because even a couple false DFS events per month will now cause customer complaints.
Probably it’s just part of Ubiquiti seems to have lost their mojo. Reminds me of this article on the once great Russian space program: http://www.nbcnews.com/news/world/russias-geriatric-space-program-creaking-n413607 But Optimus Prime is not dead, just damaged, and Mark Wahlberg will rebuild him ... oops, wrong movie.

EPMP is available for use today, Ubnt AC products, awaiting a new firmware to unlock the channels. ><I'm most interested in how ePMP scales on towers compared to UBNT If you are feq. constrained, the re-use of freq with EPMP will be highly desired. If you are not freq. constrained then ability to do higher bandwidth with the AC products will be appealing. >>>how it handles a low signal client better than UBNT when a dish gets >>>misaligned For all systems, irrespective of who makes them... the key factor is Signal to Noise Ratio... if that is decent stuff will work well, if not then they all come down to their knees.... How much and how quickly....would be very difficult to describe....(kind of like asking someone what does a rose smell like ?) >>>Consistent jitter and ping is also something I'd be interested in hearing >>>about to see how it handles VOIP and gaming better than UBNT. On any GPS based system, you will have a higher ping time....(latency) EPMP's have a very decent QOS mechanism, and voip works well . Ubnt works pretty decent too. However as a general rule.... non gps based systems are more susceptible to interference... but then keep in mind that is a relative statement, depending on the strength of the interfering signal, even the gps based units will come down to their knees.

We're building out some new sites and comparing Ubiquiti AC gear to ePMP and really would like to hear some more recent feedback on the ePMP platform since it always seems like it isn't talked about much on the list or in the forums. I know ePMP is fully certified for all bands while Ubiquiti is still only certified and running in the upper bands, except for beta which now has UNII-1 as well. I'm most interested in how ePMP scales on towers compared to UBNT and how it handles a low signal client better than UBNT when a dish gets misaligned. Consistent jitter and ping is also something I'd be interested in hearing about to see how it handles VOIP and gaming better than UBNT. Any feedback would be great.
