[AFMUG] CBRS Transition Woes

[dave]

How is everyone doing with their migration to CBRS before April 17?
I still have 30 more aps to move over with only 10 migrated.
Like chickens with our heads cut off here.
Then I get some moron who throws up a device in front of one my sectors 
and wreaks havoc for a few days setting us back for migration.

Anyone else running into such?

We finished all of our migration last Friday.

Approximately 60 cambium 450 ap’s

Some issues during transition.  Cambium was great help.  

So far working well.

We have migrated all but one AP as well.   All Cambium 450s.   Cambium is great 
help when you get to the right folks.   The normal technical support line can’t 
get off the call fast enough if you mention C, B, R, S  in one sentence, even 
if the letters aren’t next to each other.   As in “you said CBRS, we can’t help 
you with that, you need to work with your RTM” .   We haven’t had any luck 
getting response from our RTM.   We have had great luck working with Evan, but 
he is busy as heck.   We have one nagging issue in order to convert the last AP 
and we can’t fix it without Cambium help..   If anyone has any suggestions on 
how to get a response from Cambium past the normal opening of a ticket path (we 
have had a ticket open for 3 days) we’d be grateful.

Otherwise it has gone well.   The increased power is very nice.   Seeing some 
link status test numbers we never thought we would see.

Re: [AFMUG] giant cellular panel antennas

[Ken Hohhof]

I have the 12x36 IS III and I think that is probably the sweet spot in the 
lineup.  At 8x you don’t really need IS.  I think they make a 15x but that’s 
overkill for our purposes (maybe for a birdwatcher) and the price gets crazy.  
If you get one, make sure it takes AA batteries and not some weird camera 
battery you won’t have around when the batteries need changing.  They still 
work as regular binoculars when the batteries are dead, but the IS feature 
stops working.

 

The downside is they are expensive, that model is around $700.  Expensive 
enough that you will be paranoid about losing them and probably won’t loan them 
to anybody or equip employees with them.  You also might want a better case 
than what they come with, which doesn’t provide much protection.

I think we are at about 13% complete out of about 1700 clients.   So far going 
ok - but we have another year yet on our license.

Cambium doesn’t have a lot of support people familiar with the process yet but 
it’s coming along.   Just keep trying.   The good news is they seem to be much 
farther along than the other vendors.

Re: [AFMUG] CBRS Transition Woes

[dave]

Awesome,
Did any of you move to wider channel size as well for the increased 
capacity?
We  had to on most of ours due to density. I am really concerned about 
incumbents lighting up their stuff then we fight over a couple pals to 
stay alive.

How did most of you do your channel mapping for the spectrum?
I ended up segmenting into 3 30Mhz and 3 20Mhz sizes in order to 
accommodate an AB type channel depending on AP density.

Re: [AFMUG] CBRS Transition Woes

[Mark Radabaugh]

We moved a number of them to 30Mhz from 20Mhz.   I’m actually not a big fan of 
doing that since I think it’s going to be hard to sustain the 30Mhz channel 
sizes going forward and I know we will just end up loading the 30Mhz AP’s up to 
the point where we just make people mad if we have to go back to 20Mhz.

Re: [AFMUG] giant cellular panel antennas

[Caleb Knauer]

Sweet, thanks.  I recently bought 12x50 Vortex pair of binoculars that
where what I considered expensive, but I'll never not buy good binoculars
again.  The image quality is amazing.  But for the next pair I'll check out
something like this.

Re: [AFMUG] CBRS Transition Woes

That is my thought as well but we may just add some more APs LOL or 
another tower..

I am moving from a 15mhz wide net to 20 and 30
So anxious to see what 30 is going to do for us on the larger more 
congested Medusas

loading the 30Mhz AP’s up to the point where we just make people mad

We  had to on most of ours due to density. I am really concerned

How did most of you do your channel mapping for the spectrum?
I ended up segmenting into 3 30Mhz and 3 20Mhz sizes in order to 
accommodate an AB type channel depending on AP density.

Otherwise it has gone well.   The increased power is very nice.

How is everyone doing with their migration to CBRS before April 17?
I still have 30 more aps to move over with only 10 migrated.
Like chickens with our heads cut off here.
Then I get some moron who throws up a device in front of one my

Anyone else running into such?

Re: [AFMUG] PTP Microwave antenna question

Sounds like it's a big polarization cross, where's it's getting
something through but all out of alignment.  But if it's a circular
adapter then I don't see how that's possible.  Can you humor me and
take a pic of the other side of that adapter plate?

Re: [AFMUG] PTP Microwave antenna question

[Ken Hohhof]

OK, that says the antenna should be dual pol capable.  So … is a puzzlement.  
You’d expect a problem would cost a few dB, not 40 dB.  Unless H & V were 
swapped.

 

Sounds like Cambium is looking into it, maybe they come up with some ideas.

We have installed a lot of Cambium 820C radios without much trouble.  Yes, the

and installed, so it’s not like it’s our first rodeo configuring these things.

XPIC configuration.   We purchased the Cambium adapter plate that clips onto 
the antenna radio mount and presents the 820C mount for the OMT.   Take off the 
dual Horizon radio OMT, add the 820C and the RF signal is shit - in the -80’s 
from the mid 40’s.   Reverse the process and put the Horizon’s back on and the

So we thought we had a bad 820C.   It’s happened before.  So we take two

If you rotate the whole thing 90 degrees with respect to the antenna waveguide 
you could get the radios on the wrong polarizations.  
Or you are peaked on a side lobe.
Have you tried to swap radios on one end?

We have installed a lot of Cambium 820C radios without much trouble.  Yes, 
the configuration takes some getting used to but we probably have 46 links 
working and installed, so it’s not like it’s our first rodeo configuring these 
things.

 

And then we tried something new - reusing a 4’  Andrew Dragonwave antenna 
in a XPIC configuration.   We purchased the Cambium adapter plate that clips 
onto the antenna radio mount and presents the 820C mount for the OMT.   Take 
off the dual Horizon radio OMT, add the 820C and the RF signal is shit - in the 
-80’s from the mid 40’s.   Reverse the process and put the Horizon’s back on 
and the signal is fine.

 

So we thought we had a bad 820C.   It’s happened before.  So we take two 
different sets of 820C’s and test them one at a time swapping them in for known 
good installed radios on working links.   The 820C’s are fine.   

 

Okay… we forgot to test the OMT's when we did that.   So we try the OMT’s 
in the shop - and they work fine.

 

At this point the only thing left is the antennas themselves and the 
adapter plate.   The adapter plate is nothing more than a hole in a aluminum 
bushing with a couple of small steps to match diameter between the OMT and the 
antenna waveguide.   Pretty hard to screw up.

 

We have a pair of Dragonwave antenna’s in the shop that we can mount all of 
this to and try here - and we can’t get a decent signal even 20’ apart.   I’m 
at a loss at this point.   The only part that doesn’t appear to work is the 
adapter plate - and there is nothing interesting about it.

 

How the heck can this not work:

 



 



 

I can’t buy that the alignment of the antenna would need to be adjusted.   
That makes no sense in my head.   Am I wrong in that assumption?

Re: [AFMUG] PTP Microwave antenna question

With XPIC it wouldn't matter that slot 1 was talking to slot 2 on the
other side, it wouldn't know.  At least I think anyways.  Since it's
just looking for RX on the frequency it's set, and it's on the same on
both ends, and it'd still have XPD to separate the two.  You could
rotate one end 90 degrees to simulate on the office rig to test I
suppose.  Plus anyways if you can't get signal worth a flip on the
office rig, even if it was a polarity thing, that short of a link
should blast it through to something you'd see.

Only thing I can think of is that something in that tube is not
aligned, bad press fit or mill or something like that and the waves
are getting blown out of phase or similar.  There's not but one way to
put it together, and 820c -> OMT takes it to circular and you have
circular to dish.

Re: [AFMUG] PTP Microwave antenna question

[chuck]

Yeah, I was not thinking of a system with the same freq on both.
Odd.  Perhaps a rectangular waveguid somewhere in the system or the wrong 
freq waveguide somewhere.
The photos show what I would guess is 11 GHz.  That is about .750" dia plus 
or minus for most system.  I think dragonwave used .777"

Re: [AFMUG] PTP Microwave antenna question

[Ken Hohhof]

You look at Mark's photo and think what could possibly be wrong, it's a round 
hole.  How many ways are there to install a round hole, it's like the 
proverbial one car funeral procession.

And I guess with an 820C + OMT, having H and V swapped shouldn't be possible, 
and even if they were, it would still work if you did the same thing at both 
ends.  I wouldn't assume though that XPIC would straighten out an H/V swap, I 
don't think it's like MIMO on WiFi.  XPIC assumes the antenna cross pol 
rejection does most of the work and it has to clean up what remains.

I'm assuming you have the XPIC keys enabled, although that would probably 
create an alarm not the symptoms you are seeing.

Re: [AFMUG] PTP Microwave antenna question

[Mark Radabaugh]

Correct on size.  The adapter is stepped in three places to adjust the input 
and output diameters.  As far as I recall as long as the diameter is larger 
than the cutoff wavelength, larger doesn’t matter.

I think the next thing we are going to try is pulling the mounting plate off 
the Andrew/Dragonwave antenna and putting the Cambium plate and transition on 
and eliminating the Dragonwave adapter.   The fact that you can easily change 
any Andrew antenna to any other radio mounting bracket is one of the things I 
really like about the Andrew antennas.   RadioWaves can do it too but the kit 
varies by antenna size.  The Andrew one is the same from 2’ to 12’ (ok, never 
used anything over a 4’ but I’m pretty sure it’s the same).

When we used to do mailings, we would use the self-adhesive envelopes. 
No licking; just sticking.

Re: [AFMUG] CBRS Transition Woes

[Steve Jones]

we are moving 7mhz to 20, so we are good, but when we turn up cbrs im
taking it to 10 to see where the wall of worst case is
we lucked out and were able to get the vast majority to epmp
we have 20ish 450s to hang and under 50 customers to cut to them
some epmp will migrate over when foliage hits

we have til december but are trying to just be done by april so we

I've converted 100% of my certs to use Let's Encrypt. As long as your 
automated renewals are working you're golden. That's the catch though, 
LE certs are only good for 90 days, so you absolutely can't be brain 
dead about making sure automated renewals work. I use the default 
certbot client but there are many other clients.

Re: [AFMUG] PTP Microwave antenna question

[Caleb Knauer]

If that center part is press fit in slightly catawampus and not 100%
plumb then it could cause issues.  Or the pipe isn't 100% either.  But
kind of grasping at straws with that.

On the C's I've bench tested with XPIC without antennas, it'll talk to
either one IIRC if you run 2/1 or 1/2 as I've played with it.  It's
really not happy about it though.  I'd have to confirm though, been a
bit.

XPIC keys or settings wouldn't affect the raw RXL levels, it just
blows out your MSE if they're crossed.  I've seen links where they
didn't turn on anything XPIC but set it up and it works, just kinda
janky.

You could always mute one core on both sides and sanity check that way
too.  If something is crossed, it'd show the right RXL one on core and
30ish dBm down on the other core.

Re: [AFMUG] PTP Microwave antenna question

[Ken Hohhof]

I guess from the approach of not being afraid to ask stupid questions, is it 
possible you are the first customer to ever use the Dragonwave adapter?  Is it 
possible Cambium (or Ceragon if they are the source for the adapter) designed 
and made it but has never actually tested it?  And there’s some fatal flaw in 
the design?

 

This seems unlikely, but when none of the likely explanations pan out, you have 
to look elsewhere.

On the C's I've bench tested with XPIC without antennas, it'll talk to
either one IIRC if you run 2/1 or 1/2 as I've played with it.  It's
really not happy about it though.  I'd have to confirm though, been a

XPIC keys or settings wouldn't affect the raw RXL levels, it just
blows out your MSE if they're crossed.  I've seen links where they
didn't turn on anything XPIC but set it up and it works, just kinda
janky.

You could always mute one core on both sides and sanity check that way
too.  If something is crossed, it'd show the right RXL one on core and
30ish dBm down on the other core.

Re: [AFMUG] PTP Microwave antenna question

[Mark Radabaugh]

I think at this point we are just going to go back out and try it without the 
Dragonwave adapter by swapping the mounting plate on the back of the antennas 
to the Cambium plates.   We have a set of mounting plates on hand.

Wait, so ~25% of the known cases in Washington have died?  I know it hit a
nursing home but thats pretty rough.

"Of the 150 people who have tested positive for COVID-19 in the United
States, 39 are in Washington, making it the worst hit state. Ten residents
have died as of Wednesday."

Re: [AFMUG] OT Virus

its expected, if youre in a nursing home and get flu, youre normally done
~25% morbidity in a nursing home is actually a pretty damn amazing number.

Theyre going to have to delay the Census. at this point with the media
hype, nobody is going to answer their doors for the followups. my dad did
that gig for a couple years, its hard enough as it is to get them to open
the door

Re: [AFMUG] PTP Microwave antenna question

[Mark Radabaugh]

Same, but only just long long ago.   The course was Microwave and Antenna 
theory.  Prof was a younger Pakistani who didn’t believe in deodorant and spoke 
so softly your choice was watering eyes in the front or not hearing a thing in 
the back.   Midterm was a 200 point exam.   I think I scored a whopping 25 - 
which was the class average.Of course one kid had a 180.   Dual major 
premed and EE.  Early admission to Johns Hopkins.   Basketball all star.   When 
we asked him what he was doing in EE he said he wanted something to fall back 
on if he didn’t get into medical school.  Destroyed the curve for 4 years as a 
backup plan.  Couldn’t even hate him - he was too nice of a guy.

Wonder what happened to the guy…

 On the C's I've bench tested with XPIC without antennas, it'll talk to
 either one IIRC if you run 2/1 or 1/2 as I've played with it.  It's
 really not happy about it though.  I'd have to confirm though, been a
 bit.
 
 XPIC keys or settings wouldn't affect the raw RXL levels, it just
 blows out your MSE if they're crossed.  I've seen links where they
 didn't turn on anything XPIC but set it up and it works, just kinda
 janky.
 
 You could always mute one core on both sides and sanity check that way
 too.  If something is crossed, it'd show the right RXL one on core and
 30ish dBm down on the other core.

Might want to switch to peeing on them to avoid spreading anything.  According 
to the news stories droplets of saliva and rubbing your eyes are the ways it 
gets spread.  Urine might give you even more dominance than spit anyway.
