I agree it sounds like noise.

Re: [WISPA] Backhaul Link gone bonkers
Scott, I had a problem once where the link (that had worked for years) would not connect or if it did would not stay connected. I swapped the configuration of which one was the ap and which one was the station and it worked. Must have been interference of some sort.

Re: [WISPA] Backhaul Link gone bonkers
Scott, Can you give us an idea of link distance and antennas you are using. Is the 30' piece of LMR400 a factory made jumper of did you put the connectors on? Weatherproofing? Lightning arrestors? Pigtail jumpers? Trying to get an idea of what your link budget should be and where you stand now. You have said you have changed all the hardware except the LMR400. What hardware do you have and what have you changed.

It could be interference, but even 3dB of on channel interference is enough to raise the noise floor and lower your S/N radio (keep in mind in a ofdm radio the RSL numbers given assume a perfect noise free system, for ever dB of noise you have add a dB to your RSL). If you want a 54mbit OTA rate you need a much better signal for it to be reliable. If you need no less than a -74dBm signal, ensure you have a -60dBm or better signal (rule of thumb) during steady state operation.

It comes right back up, usually at about 50%. I have tried 20MHz channels, 10MHz channels, 5MHz channels with about the same results from all. I have tried 5.2-5.3 frequencies and 5.7-5.8 frequencies. The higher frequencies work better, but still not well. I'm not that familiar with the ubiquiti products, but from the data sheet the radio will put out 23 dBm and requires a -74dBm signal to work (the data sheet does not say what channel size this measurement is from, I'll assume a 20 MHz channel). What strikes me is your normal RSL is is only 3dB more than the min RSL needed to link at 54 mbit/s. This is well within the normal variance of a radio path (+-3dB), and could be causing the radios to switch back and forth between data rates (only after taking some errors). It could be interference, but even 3dB of on channel interference is enough to raise the noise floor and lower your S/N radio (keep in mind in a ofdm radio the RSL numbers given assume a perfect noise free system, for ever dB of noise you have add a dB to your RSL). If you want a 54mbit OTA rate you need a much better signal for it to be reliable. If you need no less than a -74dBm signal, ensure you have a -60dBm or better signal (rule of thumb) during steady state operation. This will give you some head room for changes in the atmosphere (K value) and other issues that pop up from time to time. If you suspect interference, try to figure out if it's local or remote and where it's at. If you can use a HP dish to knock down off path noise, do it. When I was deploying backhaul radios in unlicensed space, I made HP dish's standard on all my links.

Re: [WISPA] Backhaul Link gone bonkers
One end is just us and the 4 other links there are fine. The other is is us and at least 2 other WISPS, an FM repeater station, some public service repeaters, some commercial 2-way repeaters and ... Just looking at the tower, I don't think there is anything new, but I will ask the tower owner tomorrow. We changed everything at one end and all but the cable at the other. Other 5GHz links we have for either tower do not show symptoms of interference, but that does not mean that isn't our problem.

Re: [WISPA] Backhaul Link gone bonkers
If you replaced all gear and even tried a different coax in place of the 60' of LMR then it would have to be some kind of noise, coming in via the power lines or radiated. Who else is on the tower? Did you only replace/try different gear on one tower or did you try both ends? Have you done any spectral analysis?

Re: [WISPA] Backhaul Link gone bonkers
We battle a problem similar to this last year, turned out BAE systems was @#$% testing military radar crap in the entire 5GHz spectrum. Any national guard or military bases in the area?

Re: [WISPA] Backhaul Link gone bonkers
Also, the only way we could solve the issue since BAE wasn't willing to corporate was to go in horizontal polarity...clearly this doesn't matter on a dual-pol system.
