It probably seems that F/B ratio doesn’t need explaining. The biggest hurdle is probably when WISPs start looking at third party antennas and other shiny objects (like price and antenna gain) distract them from looking for a F/B spec around 32 dB if they ever want to do frequency reuse. The main thing this video probably does is to focus on why F/B ratio is important, even with GPS sync.
I would add that uplink interference can be worse because of varying distance to SMs. A near SM can blast through the backside of the sector and overwhelm the signal from a distant SM on the front side. ATPC can help with uplink interference by at least equalizing the received levels from near and far SMs, but ATPC typically doesn’t help with downlink interference.

From: Forrest Christian (List Account) Sent: Tuesday, December 22, 2015 3:24 AM To: af Subject: Re: [AFMUG] Cambium Headphone adapter I really wish I could find a custom cable manufacturer who I could have make these for me again. The company I was having make them kept raising the per piece prices and also the minimum order... then was shocked when I refused to order several years worth for twice what I was currently charging my customers.

You could easily buy that or anything like it, clip the rj plug off and crimp a new properly wired rj12 on it. The best kits were the ones Forrest had made that were molded and are no longer made. And of course every freakin tech lost them.

I used to have a pile of them, but I Can't find them now, and I'm too lazy to go get the components to make one. I think once upon a time, someone was selling a default plug and headphone adapter in a combo pack.
