Good stuff. His letter even offers a solid brief description of the issue:
As you know, the Federal Communications Commission is now preparing to auction the 700 megahertz slice of the spectrum. This "beachfront" band is particularly well suited to wireless broadband because it has wide coverage and can easily pass through walls.
By setting bid and service rules that unleash the potential of smaller new entrants, you can transform information opportunity for people across America -- rural and urban, wealthy and not. As much as half of the spectrum should be set aside for wholesalers who can lease access to smaller start-ups, which has the potential to improve service to rural and underserved areas. Additionally, anyone winning rights to this valuable public resource should be required not to discriminate among data and services and to allow any device to be attached to their service. Finally, bidding should be anonymous to avoid collusion and retaliatory bids.
This is the kind of thing where the president winds up with a ton of latitude, so it's definitely nice to see a major candidate committing himself to sound views on this issue -- the business interest pressure pushing in bad directions here is intense.
