Among the panel speakers was
New America Foundation scholar
Michael
Calabrese, who addressed an otherwise neglected argument offered
against white spaces by broadcasters: The claim that auctioning white
spaces for licensed use could provide a financial windfall to a
cash-strapped government. Drawing on a freshly-released NAF working
paper, Calabrese argued that industry estimates of some $10 billion in
revenues from a white space auction were based on a flawed comparison
between the "Swiss cheese" of white space bands and bands in the 700
MHz range, which are suitable for high power applications only because
they are buffered by vacant "guard bands."
