You're not.
Explain to me how single player GPS sync helps in a mixed environment of
various vendors when your equipment is in the beamwidth many other
competitors and your radios suck in the presence of adjacent channel
noise? It doesn't. It doesn't at all. Notch filters would help those
radios in that scenario, but it's not really practical unless you just
like to climb towers for kicks.

Nope. Having great success with no sync using Ubiquiti radios. Now
with new channels even better. Just like Mesh. Not ready for prime
time on my TV...

AF absolutely has sync?
As far as AirMaxAC, sure, no sync.. At this time.
In the end though, there are a lot of operators that simply don't
care about sync.
Eventually in many markets it will come to a point when you simply
run out of clean frequency, ie: using one or two or three per
tower won't cut it, due to competitors, cell offload, etc. In that
scenario where GPS sync is virtually useless (because you're
picking the best freq per direction), its pretty obvious that
there are a few radios that would currently excel in that scenario.
There are many places where we are, for instance, where multiple
competitors, city and state links, federal, etc have towers less
than a mile from us. Having the ability to "shrug off" that
adjacent and co channel noise is critical for us.

This test ignores a few kind of important details... the UBNT
and Mikrotik AC radios have no ability to sync, which gives
them a significant disadvantage. also, the Mimosa radios are
(theoretically) capable of higher throughput since they are
the only ones with the ability to use two 80mhz channels...
granted, it's pretty rare that is actually possible in the
real world, but if you had synced Mimosas everywhere, it could
be done. He's also using a $499 ePMP radio, when he should be
using a $200 Force110 PTP.
That said, the conclusion the the AF5x is the best is probably
right :P

If your criterion is performance in the presence of a
signal on a different frequency 30 dB stronger than the
desired signal, this analysis is relevant. Also, this
seems to be the scenario airPrism is designed to address.
But how often would this occur? Even if the interference
is from another non-synced transmitter on the same tower,
you’d think directional antennas would knock the
interfering signal down to less than 1000 times the
desired signal.
I guess this could be realistic if you have a point to
point link in the same band as a sector, so that a giant
dish at the other end is pointed right at your sector.

Horseshit, read the article. Did you miss the portion
where Jim said "it's the exact same chip that's in the RM5"?
I would have liked to have seen the RM5 in this test as a
baseline, but ignoring the results simply because it's N
tech in the EPMP is silly. Not only does the throughput
drop, but the LEVEL it degrades at is only "bested" by the
B5C in a few of the tests. N or not, that's a very poor
result.
I would love to see other tests posted on this from other
people, its always nice to have multiple sources to remove
any potential level of bias.
Jim did an excellent job on this and should be commended.

Dude didn't seem to catch that the ePMP is an N radio and
dismisses it
as worst of the worst. Looks to me like it would probably hold
up
comparably to its AC counterparts if you take that into
consideration.
