That I don't know, although if you take the current neutrality issues, (please don't anyone steer us there, this is an example only) I suppose it could be.
You have to consider, EVERY network, radio and TV, every cable company, and even the small dish companies would be badly impacted by this if their downlinks were interrupted. As one person who wrote the FCC said, even the small dish UPLINK companies have to get their signals some...from C-band!
I think this is a case in which our FCC chairman is caught between a rock and a hard place. He's committed to local (AM) radio but many stations derive their broadcast day FROM c-band. It's a huge cliff he's standing on, and he may only have brought this up to prove that it cannot be done based on comments and objections, thus telling the wireless and other industries that would use the bandwidth, "find another way."
The FCC does sometimes do the right thing. They just shut down an objection to commercial radio AM stations having translators. Not just one objection, but 998 of them....and the FCC Said, "No!"....the translators can be built unless there are technical issues or cross complaints by other existing broadcasters, not by people crying because they can't be "entitled" to a low power FM in their area.
We can't afford not to have those letters uploaded to the FCC by the deadline.
good question! Wish I had a better answer.
