I do not believe we have had both on the same tower. We had diverted to doing
epmp 2.4 not long after it came out as we had lots of problems with ESD on ubnt
2.4 rockets. Changed some things and they are surviving storms much better.
Tests near EPMP vs. tests on other towers (3 miles away? - totally same
environment) just revealed in dramatically different results. Not as much
speed, maybe, but at least we're getting a usable signal up to a mile or two
away. With epmp we're lucky to get a mile way.
Understand we are in THICK tree country. 900 is still our primary product

But does it actually perform worse that UBNT 2.4ghz on the same link, or is
it maybe just differences in how they calculate signal levels? It doesn't make
any sense that two different radios running on the same frequency putting the
same amount of power into the same antennas would give significantly different
signal levels...
The closest thing I've done to a comparison was playing with a Force 200
2.4ghz in wifi mode... there didn't seem to be a significant difference between
it and a PowerBeam connecting to the same AP.

hmm, i will check into that. Pretty sure with ubnt we're using kp
performance. With epmp, i think it is bundled antennas...

Jay, I suspect the difference you are seeing may be mainly in the
antennas. 2.4 GHz from any vendor should penetrate the same, the radio waves
don’t care what brand radio launched them. And I think the difference between
the platforms will be most evident in low interference environment where they
can achieve their full modulation and throughput. With low SNR, I think it’s
kind of like arguing Ferrari vs Porsche for off road racing, neither will be
able to show off its capabilities. Receiver sensitivity and bits/sec/Hz won’t
matter.

Also interested in interference rejection of the pmp450 - is there any
(in 2.4)
we are getting better foliage penetration with ubnt 2.4 than epmp 2.4 -
- and from the performance of
the epmp 2.4 i wish wish wish it penetrated better!

We have mostly PMP100 and PMP450 deployed. Some Ubiquiti we tried and
some we inherited as well. Have some ePMP we have tested but so far
have not deployed more then couple test links.
For those who have tried both ePMP and PMP450 what are the differences
you have seen in performance? Interference tolerance among others?
For those that have gone with PMP450 over ePMP what was the reasoning?
