I thought the limitation was on what a single SM did.
.....maybe mistaken.

I keep thinking at one time 450 APs were only capable of maybe 20 Mbps
but that can’t be right because I have some doing over 40. I think
Cambium said that firmware tweaking kept raising that number.
I’m asking because I have one lone site with a 450 and an omni, and
maybe a dozen subs scattered through the entire 360 degrees. So while
I am going to need more throughput, it just doesn’t justify 4 sectors,
and the cables are in conduit and I think we only ran 4 cables and we
have 2 backhauls. And it occurs to me what I need isn’t sectors, it’s
to increase the channel width to 30 MHz (450) or 40 MHz (450i). But
will a 30 MHz channel really help if the 450 AP is pps limited by the
CPU? I’m OK with replacing the 450 with a 450i if necessary. Most
sites we have at least 4 sectors, so mostly 20 MHz channels. But an
omni with a 40 MHz channel would use the same amount of spectrum as 4
sectors and 20 MHz channels.
