The noise floor comes up. As long as we have the allocation, we still 
have priority over unlicensed equipment provided we can run power above 
the power limits of unlicensed operation. Where this becomes an issue is 
that 1.2 GHz in many places is pre-empted by CARSR and with 3.3-3.5 GHz 
removed for FirstNet, we are left with few microwave bands that allow us 
to occupy the same tower as a WISP unless we land-rush the spectrum.

Nothing in Part 97 allows us to run encryption.

The concern here is that a co-secondary user has been removed. 

Unfortunately, the FCC has most recently treated spectrum without a 
carrier on it as blank space to be refarmed which is insane spectrum 
management. 

It appears that the FCC's approach is that spectrum is best used by a 
primary allocation, two secondary allocations, an unlicensed 
allocation, a space-ground application and a ground-to-space application 
at the same time. 

I did see something where someone was able to get a link working on 5.9 
GHz by selecting a region code of "licensed" in some equipment. I have 
also been told that some radios will actively prevent the use as a 
"licensed" radio, however we do have licenses.
