This is purely anecdotal, but I have noticed declined performance on
M2 (specifically, Rocket M2s in my case) where noise floor seems
higher, CCQ seems lower and customers report decreased download, but
upload is fine for them ( we offer 8 Mbps upload and they can almost
always get it). All our radios are on 5.6.9 or 6.0, both versions
seem to have this issue. I had been chalking it up to increased
interference because we've not had an A/B comparison like you've
described (replacing the one with the other), but perhaps it's more
than that. I'm getting ready to swap one of the M2s with a Rocket
2AC in mixed mode to see if things are any better. Jesse DuPont Network

Greetings, In several locations, I've replaced Mikrotik AP units with BulletM2 units; to enable AirMAX.This went quite well early in 2016 and the strategy was successful in improving performance at several locations, thanks to enabling TDMA. We converted several sites in early 2017, and almost all of them have been exhibiting symptoms of very poor performance, and awful noise floors. So for example, we would replace an RB433+XR2 with an BulletM2, using the same cables and antenna. The XR2 would be reporting a noise floor in the 'normal' range for us (around -95 to -100dBm). Then the replacement bullet would suddenly be reporting noise floors of -80dBm to -85dBm! Performance suffered along with the severe drop in SNR. Is this possibly a bad batch of radios or something along those lines? I bought them all from the same vendor at the same time. All units, both AP and SM, are running AirOS 5.6.9. Thoughts? |
