So by penetration, do you mean LOS range, or signal attenuation through foliage?
Another possibility, foliage probably depolarizes the signal, perhaps the two radios have differing ability to recover the two streams and achieve full MIMO-B throughput. Although I would expect they would both be relying on the 802.11 chip processing for this.

With epmp, i think it is bundled antennas... ----- Original Message ----- From: Ken Hohhof To: [email protected] Sent: Thursday, June 02, 2016 3:50 PM Subject: Re: [AFMUG] PMP450 vs. ePMP 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.

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?
