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.

Coordination Distances for Low Observable Diagnostic Measurement Systems

Report ID
DSO-CR-13-114

Saúl Torrico and Brian Downs
Abstract
The Air Force Life Cycle Management Center Low Observable Supportability Office requested that the Joint Spectrum Center (JSC) support its effort to develop a process to obtain spectrum-certification support for Low Observable Diagnostic Measurement Systems (LODMS) operating within the 100 MHz to 18 GHz frequency range. Specifically, the JSC has been requested to calculate coordination trigger distances between LODMS and incumbent systems operating in the 50 MHz to 18.5 GHz frequency range. These coordination trigger distances will be included in a proposed coordination procedure for LODMS operations to be incorporated into the National Telecommunications and Information Administration’s Manual of Regulations and Procedures for Federal Radio Frequency Management.

Radio Channel Impulse Response Measurement and Analysis

Report ID
NTIA Technical Report TR-11-476
May 02, 2011
Peter Papazian, John Lemmon

Abstract: This paper describes radio channel sounding measurements and analysis using pseudo-noise (PN) codes. It presents a channel sounding model and shows how channel measurements can be made. A measurement system is described that can be implemented using a combination of radio frequency (RF) hardware, high speed analog to digital converters (ADC), and signal processing software. Sampling requirements and models for describing the stochastic nature of the radio channel are discussed.
