It occurred to me the other day that white space devices, if they are ever deployed, present more of a threat to the FCC's handling of spectrum management that it does to broadcast/broadcast auxiliary uses of tv channels. Isn't the rationale of the devices that they can prevent signal interference in real time, without reference to any outside information? All you have to do is to require such an interference-detection system - and I am assuming for the sake of discussion here that these devices at some point will be able to at least fake achieving this goal - to know the "license status" of the user, and a priority level, and a way to detect the "license status" and priority level of the other signals it can receive, then arbitrate the 'best choice.' Extend that a bit further, and you can eliminate the need for the FCC to manage spectrum; replacing this function with private rights that can be enforced through federal courts. Don't worry about this causing many job losses at the FCC; the Media Bureau has many other functions, and it's not the largest bureau at the Commission. We could even permit states to handle spectrum-management, where, per my reading of the 10th Amendment to the U.S. Constitution, it should have been all along, due to an expansive reading of the "interstate commerce clause" of the Constitution. One notes that view has been severely constrained in recent decades.
