No > Is the overlap same county/neighboring county? Not in a test environment > What are the SAS controls looking like. EIRP alterations, channel changes, > channel size decreases, etc? The experimental versions of all the SAS’s as far as I am aware were not actually doing anything other than checking for incumbents. I don’t think any of them were doing actual RF propagation modeling. > How often are SAS commands being issued? (constantly, hourly, daily, weekly, > rarely, etc?) The database between the SAS’es only updates once per day. You likely won’t see updates other than overnight (at least initially). > Is there any site/POP colocation with other CBRS/SAS trial operators?

There are hooks in the SAS where you can request frequencies, but you can’t necessarily query what is in use. It’s a stupid security thing the telcos insisted on. So you can ask “can I have 3550 in 10Mhz” and it will tell you it’s not in use. And then you can ask about 3560 and it will tell you. But it won’t answer “What is available”. > Are there real time tools for monitoring your regional CBRS environment? > How have you dealt with non CBRS/SAS trial operators still operating under > the N license?
