Re: I'm Curious
I don't get it, the FM band is a worldwide simple standard. They can't easily sell it off because it would still want to be used for sporting events etc. In any case the bandwidth is small, only 20MHz all-told, and the useability is not good, you are reckoned to be able to use 1/15th for big transmitters (i.e. national networks), the figure for little low-power users cannot easily get below 1/4 due to the 4-colour theorem.
So, in all, maybe 5MHz of bandwidth in any given place. Get Tim Worstall onto it, he will agree that there is no exploitable resource here.
The DAB bandwidth, on the other hand is 174MHz-239MHz, or 65MHz, over three times as much. We currently use just seven of the available 40 bands, in London, broadcasting about 80 stations. I can't see us ever needing much more than this, if you really can't get enough christian thrash metal genre, then get a computer, or a life.
So, they could sell the DAB band, or half of it, for more money, it doesn't need such a long antenna, half what the FM band needs, but I can't think of a use for the bandwidth, given that there is "white space" radio spectrum coming along that allows all users to use what they like within reason and license-free. There will be no market at all for odd bits and pieces of RF-bandwidth when this comes in.
Don't bash DAB, it is a really good system, its hugely efficient in BW terms, allowing a national network using only one frequency and greatly reduced megawatts, it just needs more time. Also, sure, really don't abolish FM, there is no need to and no benefit forthcoming from it.
