 nationwide network. When the FCC offered the D Block spectrum in the 2008 auction, no one submit- ted an adequate bid to build out a network. The FCC has expressed a desire to move the planned emergency network to other spectrum that the public safety organizations already own. However, the public safety organizations claim that they need the spec- trum they own in other bands and it cannot be used for a nationwide network. They currently have spectrum in multiple bands including the 32MHz, 33MHz, 154- to 156MHz, 158MHz, 458MHz, 460MHz, 821MHz, and 866MHz bands. Public safety organizations had conducted a successful lobbying campaign to keep their 700MHz spectrum and for government funding for construction of a nationwide Mobile and Wi-Fi Networks network. Thus, in February 2012, Congress allocated $7 billion for the build-out of a nationwide public safety network. Prior to 2012, in an effort to fund the construction of the nationwide public safety network and to make spectrum available for mobile high-capacity networks, the FCC suggested holding incentive auctions. In these auctions, proceeds would be put into a trust SO that public safety groups could contract to build a new, compatible nationwide network. The FCC would like to hold incentive auctions for other spectrum currently held by government agencies. One purpose would be for raising money to move these agen- cies to other bands SO that spectrum can be freed up more quickly for mobile data. Cur- rently, the FCC has no authority to hold incentive auctions; this requires congressional approval. Shared Access to Spectrum to Increase Efficient Utilization Although mobile carriers are facing a shortage of spectrum due to the increasing use of smartphones to access the Internet, check e-mail, and watch video, other wireless networks use less than 50 percent of their spectrum at any given time. Shared Spectrum Company, located in Vienna, Virginia, hopes to increase the efficiency of spectrum uti- lization with its dynamic spectrum access software. This softwar
