On July 20, 2012, the President's Council of Advisors on Science and Technology (PCAST) released a report entitled Realizing the Full Potential of Government-Held Spectrum to Spur Economic Growth. PCAST, an independent council of experts from industry and academia, recognized the need to make more spectrum available for commercial use but concluded that clearing and reallocating portions of the federal spectrum would be costly, time-consuming and potentially disruptive to the federal mission. Instead, PCAST suggests that the government undergo a fundamental shift in how it conceptualizes spectrum and focus on spectrum sharing as a mainline approach to spectrum management. The Report puts forth a new architecture for spectrum use and makes recommendations for how to achieve it. Among other things, the Report recommends that the President issue a Memorandum stating that it is the policy of the U.S. government to share underutilized spectrum to the maximum extent consistent with the federal mission and requiring that the Secretary of Commerce identify 1,000 MHz of federal spectrum in which to implement shared-use spectrum pilot projects.
