I mentioned this in other threads - with a 2x2 radio, a -60 might be comprised of chains which are -63 plus -63 if perfectly balanced. Or more typically something like -62 plus a -66. But the point is, a -60 will usually be comprised of both chains being pretty good.
In 4x4, that same -60 can be comprised of (if perfectly balanced) -66 plus -66 plus -66 plus -66, if all perfectly balanced. It’s also possible that your 4x4 -60 client, the chains might be something like -65 -71 -64 -74.
So, the per-chain signal levels of an aggregate -60 is not the same in 2x2 vs 4x4 - they will be on average -3 db worse, and yet add up to the same -60 aggregate. A target of -60 as an aggregate signal might fine on a 2x2, but in 4x4, -60 is not be enough.
AND, I’ve asked repeatedly if we can somehow see and graph the receive signals on the AP - from the AP point of view. I’m told that’s not a feature, that it’s not needed, and it’s not necessary.
Respectfully Cambium, I totally disagree.
In my opinion, it’s absolutely imperative to be able to see the per-chain signals on both the SM side, and on the AP side. I’ll bet you dollars-to-donuts, if you could have seen your clients per-chain-signals, I’ll bet that your most frequently disconnecting clients, probably had some of the chains in the 70’s — and had you been able to see that, you would have had a solution years ago.
