In an announcement that surely upsets NAB and their friend Dolly Parton, Microsoft this week boldly proclaimed that a study they funded unsurprisingly values the unlicensed spectrum that will be used by White Space broadband at $100 billion. Of course that's what Microsoft hopes it's worth; the technology uses unlicensed and partially vacated spectrum created by the shift to digital television to create a new broadband delivery system. But the technology has been heavily opposed by the broadcast industry, who fear both interference and a uncontrolled rival for TV delivery. It's also opposed by broadband carriers, who obviously don't want any added competition, even if largely theoretical. Theoretically, White Spaces could be helpful delivering broadband to rural markets, and has a lot of support among deep-pocketed companies like Microsoft, Google and Dell.
