Mike,

I was just about to post the same quote, and I looked down and saw it in your 
post.

How viable is 5GHz in this situation?  I mean, we've now rolled out two AC 
buildings.  The signals go through 1 wall fine, but 2 walls or a single outside 
wall and the signal is non-existent.  If they won't be allowed to crank it up 
to 11, is it useful?  What am I missing?

Quote from the article:
T-Mobile wrote. Qualcomm said its 
testing<http://apps.fcc.gov/ecfs/document/view?id=60001104452> shows that Wi-Fi 
access points often have better throughput when sharing a channel with LTE-U 
than when sharing a channel with another Wi-Fi access point.

Here's my comment:
We'll duh.   Two AP's on the same channel is something we try to avoid, because 
"It's Bad®".  How about comparing throughput of an AP with no interference 
(Cause that's what we call two AP's on the same channel), and a AP with LTE-U 
on the same channel.

The good news is that LTE-U still has the same power limitations as other 
unlicensed uses. Telecom companies won't be able to easily provision an LTE-U 
"tower" every 30 meters within our campus, limiting their ability to cause 
interference.

Instead, I see them mostly using this fill coverage gabs by selling wifi 
routers with an LTE-U service built-in for rural and other underserved areas. 
Additionally, I see them using this to try to push their backhaul costs onto 
other providers. A Verizon could get a Cox to help foot their transit bill by 
selling their special routers to customers at just below their cost. Consumers 
would buy these routers because they are cheaper, and suddenly Verizon gets 
some "free" spectrum in that area and can manage things so the call terminates 
at the Verizon location nearest the other end of the conversation.

The biggest risk on our end is probably having students bringing routers with 
this ability into their residences, but we can deal with that the same way 
we've always done... well, almost, depending on how the whole Mariott thing 
turns out.

We can now combine three threads that we have had over the summer on this list
5 GHz, Containment, and the LTE-U controversy (this thread just started)

LTE-U and Jamming…will my Wi-Fi equipment provider enable LTE-U “containment” 
and as a University/College how can I prevent LTE-U from interfering
with my 5GHz deployment.

Oh boy…
