Re: [AFMUG] Cambium 450m uplink interference cancellation feature

[Ken Hohhof]

Back when we went down the WiMAX rabbit hole, we had a system where the web
GUI and user manual must have been taken directly from the SNMP MIB.
Explanations like it's a 32 bit unsigned integer.  Want to know more, we'll
explain what an unsigned integer is.  What does it do?  Sorry, we have no
information about that.

"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.

Oh sorry, I didn't mean to say that you were a hater.  I'm getting older, so
to act my age I have to do some general purpose grouching.

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.

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,

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
