I made that mistake also when we first went live with CBRS. I was so
happy to see all channels available. Then someone pointed out that is
only because there are no incumbents or PALs, and the SAS doesn’t
protect GAA. Obviously there are no PALs yet because the auction
hasn’t taken place.
There won’t be specific frequencies assigned to PAL holders except on
a grant-by-grant basis. But once they get a grant, no GAA user can
get a grant in that PAL protection area on the same channel. That
tells me a GAA user could get kicked off a channel because a PAL
holder got a grant and now is being protected. You could move to
another channel, but I fear that will be a manual process. Customers
go down, WISP scrambles to find another clear channel, CPI enters data
for new grant request.
I’d like to think the SAS would send a request to the domain proxy
(cnMaestro) please move the following sector to new frequency XYZ, but
I doubt that’s how it works.

Well I'm not limiting myself to that 50 MHz first off. Secondly, I
don't know what the PAL frequencies will be but I'd obviously prefer
to avoid those. Right now everything is wide open according to
Google's SAS...

I expect they’ll do both.
But are you planning to only use 3650-3700 because it’s dedicated
GAA? In 3550-3650 I don’t think there’s dedicated GAA and PAL
channels, and PAL licensed don’t come with assigned channels. So
the limit on number of PALs per county mean there would be at most
7 PALs in that 100 MHz, but I don’t think you can predict which
channels would always be GAA, other than the old NN 50 MHz.

But I don’t think we’ve experienced yet what happens if we get
kicked off a channel. Right now in GAA, we can experience the
telco firing up 80 MHz channels in GAA and causing
interference, but our grant won’t be withdrawn.
But what if the telco has a couple PALs and submits a grant
request, and the only way to accommodate their request is to
repack and assign us a new frequency. We can still get a
channel, but it may be a different channel. Is it like DFS or
LBT and we automatically get moved to a different channel, or
a narrower one, or whatever? Maybe, but I don’t think so. My
guess is our grant just gets withdrawn, and within 5 minutes
our customers are down, and we have to manually determine and
submit a different grant request to get a new channel. And we
would need to quickly determine which channel to request
because some could be occupied by other GAA users and there
would be interference.
Or will it happen automagically and I’m being too
pessimistic? Not really sure how auto would work. It seems
like the SAS only approves or rejects grant requests, it
doesn’t generate them on your behalf.

If all of them get bought I'm left with at minimum 80 MHz of
GAA. That's the worst case scenario! Before this I had 50
MHz in NN.
Now I'm not going to say I like the SAS requirement and
especially after Friday's issues showing what can happen when
someone needed to plug their coffee maker in, but any spectrum
is a good asset.

Where it gets a little trickier is when you want to change
parameters on a working system. Like frequency, channel
width, moving SM to a different AP, etc. Cambium
accommodates all of these with clever features, but it can
be confusing to the operator if you don’t do it all the
time. Some of these you do from the device and the change
just gets reflected in cnMaestro.
CBRS isn’t simple.
One other thing to get out of your brain is if you think
the SAS hands out frequencies to GAA operators in a
fashion that avoids interference. You still have to do
spectrum analysis and work around other operators just
like unlicensed. The SAS protects incumbents and PAL
holders. Other than that, it will happily give you a
grant on 3555 even if another WISP is right next to you on
3555, at least that’s my understanding.
I’m not looking forward to what happens if/when the
cellcos buy up a bunch of PALs.

After someone takes the CPI

Wireless, do you then have to
create an account on the
Federated Wireless system

just start a CBRS account with
CN Maestro and upload the
certificate on CN Maestro to
then be able to start
