I hate that. I see this with Man pages on all kinds of software too!
Open source projects have this bad habit. Just tell us what changing
the settings will do please….
Thank you,

“Telrad documentation would take a whole paragraph to tell you how to
change an integer value and not ever tell you what it does. “
Since I’m feeling grouchy, I really want to expand on this story.
There was a setting for the Wimax firmware on the Telrad 1000 called
“Frame Offset”. The manual droned on at length to tell me that it’s
an integer and you can set it from 0 to 32, and went into tedious
detail on how to use the terminal menu system to change it. I asked
our vendor support what it did and he said “we just leave it at 0”,
but could not explain what it was for. I chased that up the totem
pole with Telrad, and I think I concluded that nobody in the North
American office knew what the hell that setting would do. That one
was an illustrative example, but the entire manual was like that.

I didn’t mean to come across as a hater. The 450 features they have
given us are impressive, in my case a bit overwhelming. I feel like I
just sat down in the cockpit of a big commercial airplane.
Everything you say is true, I just need some quiet time and some brain
enhancer pills to wrap my head around all the options.
I hope the money guys aren’t leaning too heavily into “FWA is dead,
gotta pivot quick to fiber”. Yes, do new things if you have some
advantages that will allow you to be successful, but you also have to
be able to walk and chew gum.

I loved that stats were there and that documentation accurately
described what they meant and what the knobs are for. I also always
felt that Cambium was listening to the operators and trying to give us
what we needed and wanted.
If you can read, you can use the product without support, but in the
few cases I did need support it was available and I didn’t have to pay
for it. They also never BS’d me about what the product could do, and
they never failed to support a product for a reasonable amount of
time….even the 320 which was kind of a dog.
Telrad documentation would take a whole paragraph to tell you how to
change an integer value and not ever tell you what it does. We also
paid real money for support who couldn’t help us, and certain people
there made absurd claims about capabilities.
Ubiquiti gives you what they give you and doesn’t help you at all. You
can try to get answers on the forum, but the signal to noise ratio on
a support forum can be terrible. Alvarion VL was a decent product for
it’s time, but all their Wimax stuff was garbage. I’d actually take
PMP320 with all of its idiosyncrasies over any Alvarion BreezeMax or
whatever else. And the list of terrible PMP products is too long to
get into. There must have been three dozen stupid WiFi things
packaged up like they were something more awesome than just a stupid
WiFi thing.
I don’t know what’s up with Cambium haters. Did they actually use it
and objectively compare it to the competition, or are they blinded by
the desire to save a few dollars?
Anyway…..the short version of all that is that all I had to do to
appreciate Cambium PMP was try someone else’s crap for awhile. If the
worst thing we have to complain about is that a feature shipped before
a license key was on the market then that’s not a bad product.

450m and 450 in general has so many knobs you can tweak and stats to
analyze it seems they should have an AI powered advisor in cnMaestro
to help you optimize the settings.

Cambium is in a bit of scramble mode with everything going on and
folks breathing down their neck. I fully expect this to be a free
unlock at this point.

Turns out you are right, they haven’t released the license key to

to unlock MU-MIMO on a 450m Lite. My mistake.
What is Cambium thinking, put the feature in a production release
with a 30 day trial license, but not sell the key to use it beyond
the 30 days? And how are customers supposed to decide if it’s
worth the price if they don’t tell us the price?

I was told they are still talking about the final price. Either
way I can see the benefit here if you have to give up some of the
AP features to work.

I think you know the answer, it's $2000 per AP. $2500 MSRP.
I'd pay it if 3x and 4x modulations were suddenly 6x or 8x. But
they're not.

This sector has a lot of long links, subs clustered in the middle
of the sector, and several Ubiquiti WISPs in the same direction.
So the uplink modulation is poorer than downlink. The SMs have
narrow beams but the AP sees 90 degrees.
The other case where we get uplink problems is in 3 GHz when
Verizon lights up CBRS on a celltower, but we can (mostly) solve
that by matching LTE timing.

I haven't seen a 450M sector get bad uplink modulation rates
without downlink getting trashed too unless it was caused by a
misconfig on our end causing self interference.

Has anyone else tried the interference cancellation feature in
22.2 FW? (Free 30 day trial but license key is $2000.)
I tried it on what I thought was an ideal candidate sector,
but my first impression is that it helps a little not a ton.
My uplink multiplexing gain was 1.0 so I figured I had nothing
to lose.
