September 17, 2019

Senate Report 115-275, which accompanied the Consolidated Appropriations Act, 2019, Pub. L. No. 116-6, directs the National Telecommunications and Information Administration(NTIA) to report to Congress on "ensuring spectrum access for radio astronomy as commercial use of radio spectrum increases." This report covers all NTIA coordination activities from October 1, 2017 through August 14, 2019.

Commercial Spectrum Enhancement Act Annual Progress Report for 2017

July 03, 2018

NTIA submits this report pursuant to Section 207 of the Commercial Spectrum Enhancement Act (CSEA), Title II of Pub. L. 108-494, which requires annual reporting on federal agencies’ progress to relocate radio communications systems from spectrum or share spectrum that has been reallocated to commercial use. This report provides details on two separate spectrum auctions conducted by the Federal Communications Commission (FCC) that included: 1) the 1710 to 1755 megahertz (MHz) band, and 2) the 1695-1710 MHz and 1755-1780 MHz bands.

July 27, 2017

NTIA submits this report pursuant to Section 207 of the Commercial Spectrum Enhancement Act (CSEA), Title II of Pub. L. 108-494, which requires annual reporting on federal agencies’ progress to relocate radio communications systems from spectrum or share spectrum that has been reallocated to commercial use. This report provides details on two separate spectrum auctions conducted by the Federal Communications Commission (FCC) that included: 1) the 1710 to 1755 megahertz (MHz) band, and 2) the 1695-1710 MHz and 1755-1780 MHz bands.

Quantitative Assessments of Spectrum Usage

November 17, 2016

In this report, the National Telecommunications and Information Administration (NTIA) presents a summary of the results of its quantitative assessments of spectrum usage in response to the 2013 Presidential Memorandum entitled Expanding America’s Leadership in Wireless Innovation. Through this memorandum, the President sought to make more spectrum available by allowing and encouraging shared access by commercial providers to spectrum that is currently allocated for federal use.

Sixth Interim Progress Report on the Ten-Year Plan and Timetable

June 17, 2016

NTIA submits this Sixth Interim Progress Report to describe progress toward achieving the Administration’s directive to identify and make available 500 megahertz of spectrum for licensed and unlicensed wireless broadband services within ten years, while assuring the protection of vital government operations that rely on spectrum. This report covers October 1, 2014 through September 30, 2015 (FY15).

Commercial Spectrum Enhancement Act (CSEA) Annual Progress Report for 2015

April 26, 2016

NTIA submits this report pursuant to Section 207 of the Commercial Spectrum Enhancement Act (CSEA), Title II of Pub. L. 108-494, which requires annual reporting on federal agencies’ progress to relocate wireless communications systems from spectrum or share spectrum that has been reallocated to commercial use. This report provides details on two separate spectrum auctions conducted by the Federal Communications Commission (FCC) that included: 1) the 1710 to 1755 megahertz (MHz) band, and 2) the 1695-1710 MHz and 1755-1780 MHz bands.

3.5 GHz Exclusion Zone Analyses and Methodology

Abstract

This report describes the 3.5 GHz Study. It explains the assumptions, methods, analyses, and system characteristics used to generate the revised exclusion zones for small-cell commercial broadband systems to protect federal radar operations (ship and land based) from aggregate interference in the band 3550–3650 MHz. The 3.5 GHz Study’s exclusion zones are compared with the exclusion zones that were generated in the Fast Track Report, which considered macro-cell operations.

Fifth Interim Progress Report on the Ten-Year Plan and Timetable

April 14, 2015

NTIA submits this Fifth Interim Progress Report in response to the Presidential Memorandum issued on June 28, 2010.  The 2010 Presidential Memorandum directed the Secretary of Commerce, working through NTIA and in collaboration with the FCC, to identify and make available 500 megahertz of federal and non-federal spectrum by 2020 for expanded wireless broadband use.   This report covers the period from October 1, 2013 through September 30, 2014.

Eighth Annual Progress Report on the Relocation of Federal Radio Systems from the 1710-1755 MHz Spectrum Band

April 06, 2015

Section 207 of the Commercial Spectrum Enhancement Act (CSEA), Title II of P.L. 108-494 requires annual reporting on federal agencies’ progress to vacate certain wireless communications systems from the 1710 MHz to 1755 MHz radio spectrum that has been reallocated to commercial use. NTIA published the first annual report to Congress on April 17, 2008. That report covered relocation activity occurring over the period March 2007 through December 2007. This annual report documents the cumulative progress since the commencement of relocation activity in March 2007 through December 2014.
