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.

IIRC, no new UBNT products have DFS certification. Some of the newer ones 
(Maybe all?) have 5150 certification.

Hi Darin,


Comparing Ubnt AC to EPMP ... it is not a fair, apples to apples comparison.. 
one is a 802.11ac based and the other is 802.11n based system.


in regards to certs... actually, both are now certified for all of the bands... 
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.

  Hello guys, 

  Have any of you used Ubiquiti M-Series and also used ePMP now to compare the 
differences in your network? 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. Thanks
