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.

Subject: Re: [AFMUG] Very interesting post..

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.

 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.~Seth
