But with that one PMP450M AP, you'll use only one channel. Define
expensive. Expensive money-wise? Sure. Expensive spectrum-wise? Quite
the opposite.

Loading Sector with 20 Users you are at $1750 for AP and CPEs. (With
Litebeam CPEs you’re even cheaper).
With used PMP450 you are at $4950 with limited CPEs.
UBNT AC does TDMA (Mimosa does not) both do no GPS Sync (Dont know who
does when but this is how it is now).
With UBNT AC you can dare to do 20 CPEs / AP and will see very good
results. I would not scale it to > 30 now but looking at the price of
APs this is not neccesary. As it is .ac it might get an 802.11ax
upgrade in the future. UBNT-802.11n products have an upgradepath which
might not be perfect but it is not dead end like PMP320/FSK.
So yes PMP450 is expensive.

I can buy a used PMP450 AP for $1200.00. Add KP Omni for $250 so
$1,400.00. The mimosa A5-18 Omni lists for $999.00 so the PMP450 is
not that much more. I've seen used 450 SM's go for $175 for 20mbps
ones. I think the Jury is still out on how well the Mimosa is going to
scale. It probably will take years before we know for sure. I
definitely would deploy Mimosa over UBNT AC right now. Sounds like
Mimosa will have sync and anything without sync these days is
basically un-scalable.
Now on the PMP450 being expensive, yes if you add up the initial
expenses upfront costs are more. But you really have an asset with the
450 because it holds re-sale value very well compared to 802.11
radios. I just sold some old FSK SM's over the weekend for 35% of what
i paid for them 10 years ago. Assuming the 450 will still have 50-60%
of its value 5 years form now, and the ability to re-coup that money
out of the equipment, does it really costs more? I think factoring the
re-sale value down the road that it costs less....

For sure frame utilization is important. My thoughts are that if
you're loading up that many clients on an AP, maybe you ought to
be offering faster plans or removing other restrictions instead of
loading up more on an AP.
Then again, I don't deploy 450, so I don't have high AP costs to
be worried about.

As long as your downlink and uplink frame utilization is not
maxing out on the 450 you can definitely load 100 subs on an AP.
With the 30mhz channel width and soon to be 40mhz channel width
option with the 450 that will just help get more subs on per AP. I
personally have had 50 subs on an old FSK 2.4AP as recent as 1
year ago. that AP was capping out at 10mbps on the downlink side.
I have no doubt that with a 40mhz channel width 450 AP which would
net about 175-200mbps downlink on average depending on how many
subs you have running 6x-8x connections and how busy they are that
you could easily fit 100+subs on that AP. With Medusa and the
ability to push 300-400mbps per AP I wouldn't be surprised if we
start seeing some people get close to 200 subs on a single AP. Its
all about % of frame unitization.
Now my next question, is Medusa considered Beam Forming? Wasn't
the FCC originally going to allow higher EIRP on "Smart Antennas."
Isn't the Medusa about the most smartest AP/Antenna you can get?
Just think if the FCC allowed a little more power on the Medusa
how much more clients you could get because the range would be better.

I wouldn't load 100 subs onto any platform out there. There's
just not enough capacity on any of them.
Same frequency. Technology is how they do it. Tons of stuff
out there on how beamforming and mu-MIMO works.

Cambium will never lower SM price until a competitor brings
another solution to market that you could also load 100subs on
and not have the thing choke. Hopefully Airfiber PTMP will be
that. Also what I don't understand about Medusa, since it has
a bunch of smaller sectors inside of it,, is the sectors
inside of it running ABABABAB frequency re-use? Why is the
SM's not getting interference from the adjacent array if they
are all operating on same 20mhz frequency?

Update all SMs on the sector to 15.0.0.1. Hang 450m. Shut

Don't have high expectations if you have a high
concentration of SMs in one direction. But you should
really see a difference where they're fairly spread out
over 60-90 degrees. Remember it's 7x 13-degree beams and
tweaking the azimuth just a little bit may help balance
things out.

The data that Matt showed us at HQ a few weeks ago
where an operator (not in the US) with over 100 SMs!
on a single 450 sector proved that a performance boost
of 3-3.5x is possible simply by swapping to a 450m
sector. And that's still using only that single 20MHz
channel in 90 degrees. They created this thing for a
reason. And that right there is it. Nuckin futs.
