There may or may not be interference to the broadcast stations in this plan. And based on past experience, I'll assume there will be interference no matter what the coalition says. But the whole justification for using this swath of spectrum is bogus. Here is the claim:
They insist such unused white space "could deliver Internet access to every American household for as little as $10 a month, by some estimates".
Now if you believe Microsoft and Dell can deliver $10 broadband to the masses if they get what they want, then I have a bridge I'd like to sell you in Brooklyn.
