A sector Rocket AC Prism with AC Sector Antenna is $350.
Nanobeam AC 19 is $70.
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 off 450 sector and turn 450m on. Collect stats
and share. :)
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.
