New Link up for 2-3 weeks now. Using bonded 40mHz frequencies 5750 and 5825 Seem to be working fine passing our client traffic without delay with the exception of just stopping for a few seconds randomly. Folks that use real-time services like Zoom and VOIP have started complaining… Obviously, data …

Hello David, can you share this signal status of your link? How much capacity are you carrying on this link? Sincerely yours, Niragira Olympe

[Screen Shot 2020-11-12 at 6.04.30 PM] You can see a drop of several seconds around 7:02 on this graph.

Hello Mr. David, do you maintain a constant ping between the two ends of the link at least to see if the radios maintain communication? Try to know if the radio maintains communication while dropping traffic. Let us know again the signal you have on your link. Sincerely yours, Niragira Olympe

Hello Mr. David, if so, I believe the channels used are not clean. Do you use a connectorized or integrated radios? Do you have other radios in 5 GHz on the same location/tower/rooftop? What is the link range? Sincerely yours, NIRAGIRA Olympe

We do not have other radios operating in the same two 40mHz wide spectrums. The path is about 1/2 mile. That is not to say there may be others we do not know about… How do we check?

A relatively simple thing you could try is to narrow your channels down to 20Mhz widths, and to see how that fares? From your graph above, you’re not carrying a whole lot of traffic, so going to 2 channels of 20Mhz widths should be ample to carry the traffic you currently have. If that changes thi…

That all looks pretty decent. Signals are great and decently balanced too. What is your TX power on each side to achieve those -47 RSSIs? If anything, that ‘maybe’ could be a few db quieter, but I doubt your overdriving anything. Looking at PERFORMANCE, I guess Radio 2 has a bit more retransmissio…
