said by cornelius785:sorry to burst your bubble, but there are radios being researched that will hunt for the whitespace and use it intelligently. example: if the 'whitespace' radio sees a tv station active, don't transmit in that block frequency range at the moment.
my guess (hope even) is that we won't see any radio using the 'whitespace' for a couple years since well defined standards (i think there is something in the works though...) are there yet, the fcc hasn't really taken a firm stance, but more importantly, there is still plenty of research and testing to do.
Oh, don't get me wrong, I support the concept...BUT keep it unlicensed. I don't want the 'big guys' licensing away the only REAL spectrum left that the public can actually USE!
