For a while, I tried to modify my behavior to not trample the feelings of
(several of) my kids that are a bit thin skinned. But this summer, having
almost lost my wife while on vacation in Barcelona, I just said screw it. If
they want the privilege of being around me, they will just have to put up with
me. They speak of boundaries, so I decided I have boundaries too. Deal with
it or leave. You might miss me once I am gone.

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

Turns out you are right, they haven’t released the license key to
distributors yet. I was looking at the P/N and price for the key 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.
