Which and what type of urban environment?

Urban areas is just to high for 2.4 in general. 3.65 pmp450 has brought us mucho success in this area and the newest 900 450i rocks. I just need those KP higher gain cpe Ant to get a little deeper distance from the tower. We have a few customers on new 900 running 17-20 Mbs through the thickest crap around 3 mile out some less than this but with a little more cpe gain we will get this. With the dense urban area we have there is no way I could use epmp at my dense tower locations or ubnt for that matter. I do however have about 15 subs on a single epmp AP in an area that does fine with 10Mbx10Mb service rate. The coolest thing about that site is that it has 2 epmp panels back to back on same channel using the gps sync working great.

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 <blockquote> ----- Original Message ----- From: Mathew Howard To: af Sent: Thursday, June 02, 2016 4:31 PM Subject: Re: [AFMUG] PMP450 vs. ePMP 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.

With epmp, i think it is bundled antennas... <blockquote> ----- 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? </blockquote> </blockquote> </blockquote> </blockquote> </blockquote> </blockquote> </blockquote>
