It's not just TV
There are plenty of other licenced users of unused TV frequencies. At work we pay an annual fee to enable us to operate a couple of dozen radio microphones in these channels. Are our microphones in this database? How do we go about getting remedies for interference?
What happens when they sell off even more of the spectrum for mobile services, squishing the existing TV multiplexes into a smaller pool and leaving even less space for other paid-up users? Who wins?
