We have had problems with the ePMP SM signals in the 2.4 band with LOS. I understand interference is going to be higher in this band than the 5GHz, however, with signals at -60, we have had modulation fluctuate almost constantly from MCS6 to MCS15. My question is, with a good SNR and signal, why the modulation will not stay constant? Something we are doing wrong?
a. Could you do a spectrum analysis and capture the interference leve that your SA reports. Once you have that, take a look at our RSSI for DL & UL. Depending on which MCS is going up and down, see what your actual CINR is but looking at the difference between your RSSI and interference reported by SA. This is actual C/I as opposed to SNR.
I think what we should do is hold a public webinar and talk through our roadmap. There are many exciting things coming your way aross HW & SW solutions. Everything from, new subscriber modules, new exciting APs with additional differentiated technology for interference, 2.5ms frame for lower latency, FSK co-location.
The first link is a little bit lower on the RSSI side. Have you tried using eAlign (Tools->eAlign) on the SM/Slave side to see if you have the best alignment possible?
The second link appears to be well aligned. Not much to tweak here.
I would recommend running a specturm analysis on all links on both sides to make sure you are using absolutely the cleanest channel possible in that environment.
Yes, please skip 2.4 and go straight to 2.4.1. It has some bug fixes for issues in 2.4 that was causing heartburn with users. If you haven't used eAlign yet, that is absolutely the first thing you should do with your links.
