I’m not sure a 5 GHz LTE product makes sense, unless you’re talking
carrier aggregation and LAA. Otherwise I question the “magic” of “LTE
modulation”, once you try to use it in dirty spectrum. Oooooh, 256QAM.
Like we haven’t been doing that for years. I put it in the same
category as “3.65 GHz goes through trees”. Only if the noise floor is
really low, and then it’s not the “S” part of SNR, it’s the “N” part
that’s magic.
Maybe I’m missing something, but I’m not wanting to spend big bucks (and
a big power budget) to use LTE in 5 GHz. Maybe if there’s some killer
antenna technology, but I think that’s what Medusa does too. Not that
it is any better on price or power consumption.

This would be better on the price front then if that is possible.

Baicells just announced 5Ghz LTE, might be others.
The brains of the Cambium 3G Medusa is apparently supposed to be
capable of LTE modulation is what I thought I heard at the roadshow.
It would be a future software option.

Meaning an unlicensed radio that uses LTE modulation methods.

What's nice LTE? Baicells?
A Telrad eNB might be "only" $7k, but you'll be north of $9k by
the time you figure out all the licenses you need.
I'd be curious about a 3.65 Medusa, but I wonder if I can set
TDD parameters that will line up with our existing LTE frames.

It's gonna be on display in Vegas. I'm not even in USA so
the CBRS stuff isn't really affecting us right now, but when
you start looking at 9k per ap you could get some nice LTE
instead.
It's just surprising being 2k more than the 5ghz pmp450m.
Especially with the cost of the SM being higher as well, but
maybe the 450b 3.65 will solve that? Time will tell I guess.

But if it’s really available “soon”, I’m a little
surprised, I was afraid they would wait to see what the
FCC did with the PAL auction rules. Also whether the
industry decided that CBRS is only for LTE devices, even
for fixed.
And I thought Ubiquiti had trademarked the term SOON™.
Anyway, I think something like LTE or cnMedusa is going
to be necessary for CBRS, especially with the cost of
paying a SAS vendor for each location and the cost of
acquiring PAL licenses, and then only getting 10 MHz
channels. You don’t get much capacity from 10 MHz of
spectrum unless you have all the fancy tricks like beam
steering and bidirectional MU-MIMO, and of course at
least 256QAM.

It's available very soon, but the pricing is nutty. $9k

We have a few towers with TOWER TOP control and
management.
The ones I designed are 24v and 48v.
We have only CMM4 boxes with the Planet switches
which I use LC the hybrid cable comes from Besttronics.
We have a #12 stranded pair in each of these. I have
to have transtector Part#1101-626 at top and bottom
to meet our
surge protection compliance.
Since those sites have been installed I have had
zero issues.
Seems that 3.65Medusa has made us change to a more
direct connection so my box design will have to be
modified.
All of the Orange tag cables will have to be removed
since the packet flux will not support the new power
requirements
Here is one design we have plans to deploy next week.

Are most people using SC or LC at the top of the

but I understand the advantage in SC on a tower
where it's easier to work with larger things.
What's the next bigger enclosure? Could you put
something like this on a swinging panel where I
could run a trunk cable into it and then plug
individual patch cables going to each radio?
Maybe easier on you if you just make it work
with something else on the market, like these
panels from FiberStore where someone can just
get whatever panel they want (LC\SC\whatever)?

The goal is to emulate one of these:

https://www.raycap.com/wp-content/uploads/2018/04/DC6-48-60-18-8C-EV_320-1315-1.pdf
Power and fiber in one box, transition from
trunk to the ground to the radios.
I'm sure they'd sell well.

Can put in a patch panel. Just a mechanical
thing to solve.
But patch panels have cutouts for couplers. And
different couplers need different size holes in
the part that holds them in.
So if someone could tell me which coupler will
always be needed, then this is easy.
Otherwise I have to offer a variety of coupler
options and that multiplies my part numbers etc etc.
Happy to do that but not if I only sell 1 per
month.

When do we see a 48v one of these? Also, more
density?
http://store.packetflux.com/sitemonitor-4-channel-relay-output/
When do we see one of these with a fiber patch
panel and slack storage?
