Recently I’ve run into a few customers with really good signal, SNR and modulation but constant loss of registration and drops in the SNR graph. I move them to an adjacent sector and their signal drops, but the problem goes away. The most recent case was a customer on a 450b high gain at 2 miles with a -54 signal and really bad dropouts. Between the dropouts though they were at 8X and really good SNR on both HPOL and VPOL.
I didn’t think the signal could be too strong until it was in the 30’s or 40’s. Could -54 be too hot?
What about the SM receive target, can there be a problem is the signal at the AP is above or right at the target? Usually I leave the default of -52, sometimes if I remember I change it to -62.
