birds is magic

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.

  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

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 usd....

          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 tower? I want to 
use LC most everywhere I can, 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)?

            https://www.fs.com/products/68962.html

            The goal is to emulate one of these:

            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?
