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.

Do you think the company that spend millions to operate in their PAL blocks 
would be willing to operate in GAA at all?

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channels in GAA and causing interference, but our grant won’t be withdrawn.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just gets withdrawn, and within 5 minutes our customers are down, and we have 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.

If Cambium support is ignoring your ticket, grab the email address of the guy 
sending out emails about the cnMaestro Cloud software update progress and send 
him a nice email asking for help.

The cnMaestro CBRS support folks are actually very helpful.  I’ve even had them 
remote control my screen, fix things, and teach me how to do stuff.  The trick 
may be getting the ticket past Level 1 support and assigned to the right people.

ok thats what i thought, i did all that have two AP's that are showing up in

ticket in with cambium for the last 3 days and nothing so far.

After someone takes the CPI test and gets the CPI certificate from Federated 
Wireless, do you then have to create an account on the Federated Wireless 
system controller website or can you just start a CBRS account with CN Maestro 
and upload the certificate on CN Maestro to then be able to start on-boarding 
devices?
