Also remember, its not only about doing the spectrum analsys upfront, but
also an issue of choosing a broadcast site, where the management is savy
enough to manage the spectrum use correctly at the site. Whether or not you
interfere with colocated equipment should have been caught before any gear
was ever even turned on, or a dollar spent in onsite time. Thats the
advantage of paying for the use of spectrum from a site. Many people will
install unlicensed gear, without contractually having the right to deploy it
in the first place. Many Licensed carrier don;t understand its the
appropirate practice to. So often, if you've paid for it, and they haven;t,
you can make them take it down.

Funny you mention that, But you are right. We are located on a tower with
a
2.4 WM and a 5ghz WM. We put our stuff up, ran the SA and went holy S***.
We
were able to move around them. But I forgot about them when I moved some
channels around, and sure enough about 3 months later I was taking to the
area tech and I asked how everything was working....... They never could
figure out why their t-1 radios kept dropping until I asked what channels
they were running.
Canopy gave them some problems, but we never saw anything. So now I have
those channels blocked out......

Not that this is a good practice...but
Wmux radios are extremely sensative to interference on the Rx size (a wiff
of anything takes it down)
Figure out the Tx/Rx spread (may be 5.3 GHz on that particular site), and
shut them down on the Rx side -- maybe then they'll talk =)
-Charles
P.S. -- if it's a short range shot, they can probably go licensed now for
the same price as unlicensed, and they'd get out of your hair completely

Triangulate in on where it's coming from and ask the folks that own

It might be cheaper to pay them to change polarities than it is to
reset
your plan.
I think the concensus - western multiplex - makes sense. And probbly a
cell carrier. I do totally understand legacy equipment and such, but
dammit I could get a few hundred mbps out of that same chunk and have
channel space left over... but again that's using moden equipment.
I know I probbly have zero chance of sucess, but would anyone think
(provided I can find the operator) that we could work something out -
either like a polarity change as marlon suggested, or just buy them some
more spectrally effecient gear...? I understand they may need to have an
actual T1 electrical interface, but there are a few players that can
actually do this job with much much less spectrum. I know of ceragon and
their fiberair, as well as redline can do this. I've never heard of a
deal like this but it would be helpful. Otherwise I'm going to have to
change plans and that's gonna be a little expensive. Sort of wish I'd
done an SA first but it's in the middle of nowhere and I just assumed
based on past experience it wasn't going to be a problem... WRONG!
