Intro: On March 18, FCC Auction 73 bidding round 261 ended and, after 38 days and $19.592 billion in bids (almost double the $10 billion the FCC had hoped for), the FCC closed out the auction. In this podcast we review and discuss the auction results.Mike: Gordon, can you give us an overview of the auction results?Sure Mike - this comes from the FCC auction website linked up in the shownotes. Rounds: 261 (started on 1/24 and ended on 3/18) Bidding Days: 38 Qualified Bidders: 214 Winning Bidders: 101 Bidders won 1090 Licenses *Auction 73 concluded with 1090 provisionally winning bids covering 1091 licenses and totaling $19,592,420,000, as shown in the Integrated Spectrum Auction System. The provisionally winning bids for the A, B, C, and E Block licenses exceeded the aggregate reserve prices for those blocks. The provisionally winning bid for the D Block license, however, did not meet the applicable reserve price and thus did not become a winning bid. Accordingly, Auction 73 raised a total of $19,120,378,000 in winning bids and $18,957,582,150 in net winning bids (reflecting bidders' claimed bidding credit eligibility), as shown above. Mike: Before we get into the auction results, can you give us an overview of the different spectrum blocks? I know we've done this before but - how about a quick refresher?Sure Mike - this comes from a blog I wrote back on January 14.

Back in 2005 Congress passed a law that requires all U.S. TV stations to convert to all digital broadcasts and give up analog spectrum in the 700 MHz frequency band. This law will free up 62 MHz of spectrum in the 700 MHz band and effectively eliminate channels between 52 and 69. This conversion, which has a deadline of February 18, 2009, has freed up spectrum that is being split up by the FCC into five blocks:

• A-Block - 12 MHz, split up into 176 smaller economic areas
• B-Block - 12 MHz, split up into 734 cellular market areas
• C-Block - 22 MHz, up into 12 regional licenses
• D-Block - 10MHz, combined with approximately 10MHz allocated for public safety, a single national license.
• E-Block - 6 MHz, split up into 176 smaller economic areas

So in summary, each spectrum block in the 700 MHz auction, except for the national public safely D-Block, has been assigned an area designation by the FCC. All FCC areas, along with names, county lists, maps and map info data can be found on the Commission's website linked here.Mike: How about a quick review of the D-Block again?Sure Mike, this also comes from that January 14 blog:

The D-Block lately has been most interesting to watch. Early on it appeared Frontline Wireless would be one of the biggest bidders for D-Block spectrum - the company was setup for D-Block and had worked closely with the FCC on putting together specifications for the spectrum. Frontline built a formidable team including Vice Chairman Reed Hundt, who served as Chairman of the FCC between 1993 and 1997.
