“America's future competitiveness and global technology leadership depend, in part, upon theavailability of additional spectrum. The world is going wireless, and we must not fall behind…. Expanded wireless broadband access will trigger the creation of innovative new businesses,provide cost-effective connections in rural areas, increase productivity, improve public safety,and allow for the development of mobile telemedicine, telework, distance learning, and othernew applications that will transform Americans' lives…. This new era in global technology leadership will only happen if there is adequate spectrumavailable to support the forthcoming myriad of wireless devices, networks, and applications thatcan drive the new economy. To do so, we can use our American ingenuity to wring abundancefrom scarcity, by finding ways to use spectrum more efficiently. We can also unlock the value ofotherwise underutilized spectrum and open new avenues for spectrum users to derive valuethrough the development of advanced, situation-aware spectrum-sharing technologies.” -President Obama, June 28, 2010 Summary of the two DOC/NTIA reports 1)A Ten-Year Plan and Timetable to make 500 megahertz of Federal and non-Federalspectrum available for wireless broadband use. The Department of Commerce’s (DOC) National Telecommunications and InformationAdministration (NTIA), in collaboration with the Federal Communications Commission (FCC)and other Federal agencies, prepared a Plan and Timetable that: 1) identifies an initial list ofcandidate spectrum bands; 2) outlines steps to determine additional candidate bands; 3) sets aprocess to assess and evaluate their feasibility; and 4) identifies actions necessary to make thatspectrum available for wireless broadband use within a decade. The Plan and Timetable identifyover 2,200 megahertz of Federal and non-Federal spectrum that will be evaluated for potentialopportunities for wireless broadband use. (See attached table.) NTIA prepared the report pursuant to the June 28, 2010 Presidential Memorandum that directedthe Secretary of Commerce, through NTIA, to collaborate with the FCC to produce a ten-yearplan and timetable for making available 500 megahertz of Federal and non-Federal spectrumsuitable for wireless broadband use, while taking into account the need to ensure there is no lossof existing critical government capabilities and the need for appropriate enforcementmechanisms and authorities. 2)Fast Track Evaluation of the 1675-1710 MHz, 1755-1780 MHz, 3500-3650 MHz, and4200-4220 MHz and 4380-4400 MHz bands. NTIA, at the request of the Office of Management and Budget,the National Economic Council,and the Office of Science and Technology Policy, and in collaboration with the FCC and otherFederal agencies, performed a “fast track” review of some of these bands to determine whetherany spectrum could be made available for wireless broadband within five years. NTIA identified and evaluated four bands for this review: 1) 1675-1710 MHz; 2) 1755-1780 MHz; 3) 3500-3650MHz; and 4) 4200-4220 MHz and 4380-4400 MHz. NTIA recommends that 115 megahertz(1695-1710 MHz and 3550-3650 MHz) be made available for wireless broadband in the nextfive years, contingent upon timely allocation of funds. This is an important down payment on theAdministration’s commitment to address the growing demand for wireless broadband services.The evaluation of the 1755-1780 MHz band could not be completed by an October 2010deadline for identifying the initial tranche of spectrum. This band will continue to be a priorityfor analysis in the Plan and Timetable. Ten-year Plan and Timetable for 500 megahertz NTIA has identified 2,200 megahertz of spectrum to evaluate for wireless broadbandopportunities, including the four fast-track bands, as candidate bands for review.The reportprovides a roadmap for identifying wireless spectrum assigned to both Federal and non-Federalusers that can be allocated for wireless broadband, as well as for using all spectrum moreefficiently. Review Mechanisms:•NTIA will work in collaboration with the FCC to consider Federal, shared, and non- Federal bands for potential commercial broadband use.•NTIA will prioritize the candidate bands for analysis based on a variety of factorsincluding how the band is currently being used, industry interest, relocation cost forFederal users, and the likelihood that the band can be repurposed within ten years.The highest priority bands will be evaluated first.•NTIA will convene the Policy and Plans Steering Group (PPSG) to perform theevaluations of the candidate bands.•In order to reach the 500 megahertz goal as rapidly as possible, bands will bereviewed on a rolling basis. The recommendations will be released as the review ofeach band is completed.•The U.S. Chief Technology Officer, working in cooperation with NTIA and thePPSG, will undertake reviews of agencies’ spectrum usage to ensure that the FederalGovernment utilizes spectrum most effectively.•NTIA will al
