Alpha wireless is putting on a cbrs webinar and cambium will be there,
hopefully the Q&A is similar to the cambium even, it's worth signing up for it

There is something weird there though - a few WinnForum presentations have
the GPWZ’s expiring by 2023. I’m guessing that is when the last of the
licenses that have GWPZ’s expire even though there are NN licenses that last
longer. I’m guessing none of those later expiration date licenses had
registered locations in 2015. Hum… actually that makes sense - to have a
license that expires in 2025 you would have had to get it on or around 2015 and
would not have had registered locations at that time.

Mark,
Do the GPWZ areas expire on April 17th 2020 also? Or they expire whenever
the grandfathered NN license expires?

from interference from a CBRS operator, but a person better make sure they
don't have any of those "bodies in the trunk" if they try to call the FCC for
help with that. We'd also likely be stuck with old equipment in that case. If
we use the advantages of the new rules then it's hard to argue that we should
be protected by the old license, and if we're using old Wimax gear with our old
license then we'll be less competitive than someone with modern electronics,
another 100mhz, and 8 or 10 more db in the link budget.
It’s not theory that you will be protected from CBRS interference if you
are in the grandfathered wireless protection zones (GWPZ’s). The SAS is
REQUIRED to honor the GPWZ and CAN NOT assign a CBSD a frequency between 3650
and 3700Mhz. You do not need to contact the FCC if you are getting
interference from a CBSD - you need to contact the SAS the screwed up and
granted the request.
Note this is a little problematic - you can’t get a 3650-3700 frequency
for a CBSD in a GWPZ even if it’s your own equipment. There is no current
mechanism in the SAS to say “It’s my GPWZ and I want to change the equipment
I’m using to SAS operation and use the same frequency. You would need to
unregister the existing 90z equipment and then hope that someone else doesn’t
get the channel.
