Original wording of question: What is fractional network access? 

I'm having trouble figuring out what this term actually means, though I can find a ton of whitepapers about how some-standard-or-another means to support it. 

I know it's related to the fact that wimax makes use of it's operating on subchannels, but 3g takes up an entire band. How would that work with 3g, then?
