The space right now is planned for television broadcasters. What can they do with that space? Well, moving from analog to digital allows a more efficient use. That's why you're clearing up what you're mentioning there. They get to keep a level of spectrum similar to what they were using before, but it's used more effectively. They can use what they have in order to do a variety of things.
Right now most broadcasters are aiming towards providing high-definition television. That's what Canadians and their customers seem to have told them they want. So as opposed to using it for other purposes, they're really aiming at digital television; however, it can be used for a variety of other uses, such as additional TV channels or other forms of communications.
