REPORT TO THE PRESIDENT U.S. Department of Commerce Rebecca Blank, Deputy Secretary Lawrence E. Strickling, Assistant Secretaryfor Communications and Information February 2013 As directed by Congress in Section 6401(a)(3) of the Middle Class Tax Relief and JobCreation Act of 2012 (Tax Relief Act), this report identifies 15 megahertz of spectrum between1675 MHz and 1710 MHz for reallocation from federal use to non-federal use.1Specifically, theSecretary of Commerce, through the National Telecommunications and InformationAdministration (NTIA), recommends that the Federal Communications Commission (FCC)reallocate the 1695-1710 MHz band for commercial use.2 Thisrecommendation reaffirms NTIA’s January 2011 conclusion that the FCC shouldrepurpose the 1695-1710 MHz band for wireless broadband use on a shared basis, as NTIAidentified in itsFast Track Report.3NTIA issued that report in response tothe President’s June2010 directive to identify 500 megahertz of spectrum for wireless broadband services that willhelp trigger the creation of jobs and innovative new businesses, provide cost-effectiveconnections in rural areas, increase productivity, and allow for the increase use of mobiletelemedicine,and other new applications that will transform Americans’ lives, while ensuring noloss of critical government capabilities.4Under the President’s initiative,NTIA examined theviability of accommodating mobile broadband systems in the 1675-1710 MHz band andconcluded that the 1695-1710 MHz band segment could be made available for wirelessbroadband systems subject to geographic sharing requirements based on establishing exclusionzones around specified federal meteorological-satellite earth station sites.5 Soon after enactment of the Tax Relief Act, and in recognition that the exclusion zonesspecified in theFast Track Reportwould limit the ability of commercial operators to deploywireless broadband in some of the top U.S. markets, NTIA sought the advice of its CommerceSpectrum Management Advisory Committee (CSMAC or committee) on options to minimize the impacts of exclusion zones on anticipated commercial broadband operations.6In May, 2012, theCSMAC established a joint government/industry working group on 1695-1710 MHzMeteorological-Satellite issues as a venue for federal agencies to examine and discuss the issueswith industry experts and to facilitate information sharing among the stakeholders. Over the pastfew months, this working group has been developing ways to facilitate the introduction ofcommercial wireless broadband in this 15 megahertz of spectrum through improved modeling ofcommercial wireless networks and the possible reductions in the size of exclusion zones. The working group has been crafting recommendations for the CSMAC to consider, suchas alternatives to theFast Track Report’sgeographic exclusion zone approach. Based on a statusupdate provided by the working group at the January 2013 CSMAC meeting, the working grouphas made significant progress toward an effective and efficient spectrum sharing framework.7The full CSMAC will soon make its final recommendations to NTIA based on the workinggroup’srefined technical parameters for the commercial and federal systems and the analyticalapproach for developing geographic sharing criteria.8Accordingly, NTIA is confident that theFCC can proceed now with its process to repurpose the 15 megahertz between 1695 MHz and1710 MHz pursuant to this recommendation even though the CSMAC has not completed itswork as of the transmittal date of this report. During its meeting in February 2013, the CSMACwill likely recommend a regulatory framework for sharing in the 1695-1710 MHz band that willallow flexibility for and coordination of actual commercial system implementation within theprotection zones around federal meteorological-satellite receive sites.9NTIA will assess thefinal CSMAC recommendations and provide additional information to the FCC that will be usedin the rulemaking proceeding called for in the Tax Relief Act.10 The results of these collaborative efforts will better inform the FCC’s proceedings andthe President’s additional responsibilities under the Tax Relief Act.11These results will also validate the benefit of cooperative interaction between industry and government to find ways ofmaximizing access to the spectrum for commercial services while protecting critical federaloperations.
