This is not accurate. Contact your SAS and they will absolutely cut the
pie up to avoid interference... that is their job.... and then will do it.
We just moved Verizon around in our area so we could both exist.

Remember that as a GAA user just because you are in the SAS you do not
have first in rights. The SAS only protects the licensed PAL holders.
Anyone who shows up to play in the GAA channels has to fight among
themselves the same as you do on any unlicensed channels.
I repeat, the first users on a GAA channel in the SAS have ZERO
protections from other GAA users, even if they were already shown in the
SAS as active registered users. The SAS will not protect you from
someone else turning up equipment on the same GAA channel.
Thank you,

I’ve been seeing this thread on the list for a while but hadn’t really
read it. Probably worth keeping in mind when we do turn our stuff on to
see how much interference there might be

T-Mobile took over lots of 2 and 3Ghz stuff from Sprint...maybe

LOL, Mike you got to get in the game bro.
I typed that up half asleep as well.
It’s not always that easy, but yes we have done all that.
You really think Crown, SBA, American care?
Crowns answer: 3ghz isn’t licensed anyone can use it plus you
would need to contact the interfering party directly
Well they are partially right.

I just woke up, so maybe my reading comprehension isn't the best
yet.
Can't you use a spectrum analyzer to track down the sources of
the interference and then work with the tower owner on who it is
that's on that tower and contact information?

*Subject: *[AFMUG] T-Mobile PALs and CBRS GAA
Good morning AF Geeks-
Someone help me understand this better. Several questions below.
We operate in six counties in Indiana. Some rural some not so much.
In our main county (johnson) we are starting to get interference
even when we are connected to the SAS.
While we cannot prove anything yet, each tower we are seeing
this on recently had new T-Mobile equipment deployed.
I reached out to our attorney, Steve Coran, this week and asked
him to pulled the county PAL winners. Listed here:
PAL winners for Johnson County, IN:
XF Wireless Investment, LLC (Comcast) -- 20 MHz
Actel, LLC (CenturyLink) -- 20 MHz
Wetterhorn Wireless L.L.C. (DISH) – 30 MHz
-Century Link has zero cell services of any kind in our county
and currently not deploying in fixed wireless.
-Comcast floats off Verizon
-Dish also has zero cell services of any kind in our count
So what we ended up with is PAL winners who have nothing to
offer locally yet unless subleasing.
Questions are:
is T-Mobile subleasing PAL’s from any of these three?
Is T-Mobile illegally just rotating PAL’s anywhere they want in
the country instead of just local counties?
Anyway to clearly isolate the offending carrier sucking up so
much spectrum and causing all the interference?
Another member brought up T-Mobile as a possible offender. Did
any data come from that?
What time of the day do the SAS databases sync with each other
and does this force other carriers to cut back on total GAA –
share nicely?
Has anyone found the other SAS providers to be better then
GOOGLE. Starting to think their system is worthless or
inaccurate. Truth is I think this whole concept of spectrum
sharing is poorly handled and not fully tested on 3g.
If a carrier is on the same tower, how will that affect sync? I
ask because we found some very interesting work arounds and
results with upload when we started playing with sync
settings…ie distance, frame, channel.
If the customer SM is moved from one spot to another or from a
roof to a post how badly does this affect the calculations on
the SAS side?
Things we have discovered:
* Even when we find noise floors on spectrum analysis in a
reasonable range and move to the cleaner channel on the SAS
the interference still trashes the uplinks.
* In some cases the SAS is blocking the cleanest of channels
which could be PAL related.
* In some cases customer SM’s going off other ‘unaffected’
sites nearby may get knocked offline by the new noise.
* In some cases we have had to drop off the SAS and found
switching to other regulatory has allowed us to switch to
cleaner channels and stabilized subs. (which is exactly
what we shouldn’t be doing)
* We have a ton of 450m units going on towers as both new and
upgrades. I am concerned that the more urban areas will
struggle with capacity since we have to break this up across
multiple sectors.
History and Equipment:
Again this seems very isolated to our more urban deployments
which have historically been awesome in the 50Mhz channels prior
to CBRS turn ups.
Our more rural areas are not seeing this issue at all.
All three locations have very specific and brand new T-Mobile
equipment so this has been our assumption of the cause without
such proof.
Equipment on these commercial towers has been no more then two
450i AP’s with KP 120’ sectors (pending 450m upgrades).
