Spotlight on NTIA: Edward Drocella, Chief of Spectrum Engineering and Analysis Division, Office of Spectrum Management

June 2, 2015

This post is part of our “Spotlight on NTIA” blog series, which is highlighting the work that NTIA employees are doing to advance NTIA’s mission of promoting broadband adoption, finding spectrum to meet the growing demand for wireless technologies, and ensuring the Internet remains an engine for innovation and economic growth.

Ed DrocellaIn addition to ensuring that federal agencies have the spectrum they need to carry out important missions for the American people, NTIA’s Office of Spectrum Management in recent years has been working hard to help meet the President’s goal of making 500 megahertz of spectrum available for wireless broadband by 2020.

Coordination Distances for Low Observable Diagnostic Measurement Systems

Report ID
DSO-CR-13-114
October 09, 2013
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.
