clearwire is coming out with wimax systems at 2.5 gigahertz, and it works very well. you go beyond 3.5 gigahertz or so and the physics starts interfering. so there is a limit to the frequency range. >> host: for the sake of clarification, we talked about broadcasters getting spectrum back, chairman genachowski said the plan would be a voluntary plan, so tv stations could voluntarily return the spectrum and then share in the proceeds of the auction of that spectrum. obviously, that would take legislation, but just to clarify that because there had been fears early on by the broadcasters that the fcc would, in fact, kind of involuntarily reclaim part of that spectrum. >> guest: no, thank you, paul, for claire tie being that. don't get me wrong, i don't think there's anything wrong with redistributing the spectrum, but to believe that that's going to solve this problem is naive. the benefits, notwithstanding peter cursed me a little bit at the beginning, the benefits of broadband, of the ability to send various kinds of data between us is going to be enormously -- we've
