3.5 GHz Radar Waveform Capture at Point Loma

May 11, 2017
Author(s)
Paul D. Hale, Jeffrey A. Jargon, Peter J. Jeavons, Michael R. Souryal, Adam J. Wunderlich, Mark Lofquist
We describe measurements to create a library of high-fidelity waveforms of federal incumbent radar signals currently operating in the 3550 MHz – 3650 MHz (“3.5 GHz”) band. In the first phase of assembling this library, measurements were collected at Point

John Padgette, John Bahr, Mayank Batra, Marcel Holtmann, Rhonda Smithbey, Lidong Chen, Karen Scarfone
Bluetooth wireless technology is an open standard for short-range radio frequency communication used primarily to establish wireless personal area networks (WPANs), and has been integrated into many types of business and consumer devices. This publication

Dynamic Appliances Scheduling in Collaborative MicroGrids System

May 1, 2017
Author(s)
Hamid Gharavi, Hasnae Bilil
Abstract—In this paper a new approach which is based on a collaborative system of MicroGrids (MG’s), is proposed to enable household appliance scheduling. To achieve this, appliances are categorized into flexible and non-flexible Deferrable Loads (DL’s)

Life Time Dosimetric Assessment for Mice and Rats Exposed to Cell Phone Radiation in Reverberation Chambers

March 17, 2017
Author(s)
Perry F. Wilson, John M. Ladbury, Galen H. Koepke, Yijian Gong, Myles Capstick, Keven Kuhn, David L. McCormick, Ronald L. Melnick, Niels Kuster
In this paper, we present a detailed life time dosimetry analysis for individually housed rodents exposed to radio frequency (RF) signals. The unrestrained rodents were exposed in reverberation chambers for 2 years at three whole-body averaged specific

LTE impacts on GPS

This report describes the test methodology from “LTE impacts on GPS: Test and Metrology Plan” developed by National Advanced Spectrum and Communications Test Network (NASCTN), and data that are the result of executing the test method. The fundamental goals

Effects of Wireless Packet Loss in Industrial Process Control Systems

February 9, 2017
Author(s)
Yongkang Liu, Rick Candell, Nader Moayeri
Timely and reliable sensing and actuation control are essential in networked control. This depends on not only the precision/quality of the sensors and actuators used but also on how well the communications links between the field instruments and the

2015 Location-Based Services R&D Summit Report

January 30, 2017
Author(s)
Harris Feldman, Adam H. Danielson
The Public Safety Communications Research Program (PSCR) convened over 80 stakeholders at the National Institute of Standards and Technology (NIST) Boulder, CO campus to build on the findings presented in the 2015 Location-Based Services (LBS) Summit- held

2016 PSCR Analytics Summit Report

January 30, 2017
Author(s)
Jeremy E. Benson, Harris Feldman
PSCR hosted over 80 stakeholders from industry, academia, public safety, and government to the NIST Boulder campus in August 2016. The August summit was a follow-up to the Public Safety Analytics R&D Roadmap, published earlier in 2016. This document

Impact of timing on the Proximity Services (ProSe) synchronization function

January 8, 2017
Author(s)
Samantha Gamboa Quintiliani, Fernando Cintron, David W. Griffith, Richard A. Rouil
Long Term Evolution Advanced (LTE-A) introduces a new feature called Proximity Services (ProSe), which enables device-to-device (D2D) communication between User Equipment (UE) and the capability to operate out-of-network. In order to establish a D2D

Foreword

Author(s)
Sokwoo Rhee
For IoT to be broadly adopted, it is important to apply the concept to many applications at scale in our everyday life. Using these advanced technologies, our communities and cities can be more intelligent, secure, and resilient. The Hardware and

BLER Performance Evaluation of LTE Device-to-Device Communications

November 9, 2016
Author(s)
Jian Wang, Richard A. Rouil
Long-Term Evolution (LTE) supporting Device-to-Device (D2D) communication is a feature introduced in 3rd Generation Partnership Project (3GPP) release 12. D2D communication is critical in public safety applications, which enables communication among first

A Tetherless, Absolute-Time Channel Sounder, Processing, and Results for a Complex Environment

November 4, 2016
Author(s)
David R. Novotny, Alexandra E. Curtin, Catherine A. Remley, Peter B. Papazian, Jeanne T. Quimby, Richard Candell
we present a channel sounder that can operate without a tether and still maintain an absolute time reference between the source and receiver. Based on a sliding correlator, with synchronized rubidium clocks to generate phase references for the up- and down

Calibration of Time-interleaved Errors in Real-time Digital Oscilloscopes

November 1, 2016
Author(s)
Jeffrey A. Jargon, Chihyun Cho, Joo-Gwang Lee, Paul D. Hale, Peter J. Jeavons, John B. Schlager, Andrew M. Dienstfrey
A novel method is proposed for the calibration of channel mismatch in a time-interleaved real- time digital oscilloscope (RTDO). A simple simultaneous equation is derived from the Fourier transform of the time-interleaved signals requiring only a transfer

Model Verification with Measurement Uncertainty

Author(s)
Dylan F. Williams, Richard A. Chamberlin, Jerome G. Cheron, Wei Zhao, Urteaga Miguel
We verify a model for state-of-the-art 250 nm heterojunction bipolar transistors with large-signal measurements. We demonstrate the propagation of correlated measurement uncertainties through the model-extraction and verification process, and use them to

Demultiplexing Spectrum-Sharing Field Sources with Distributed Field Probes

July 24, 2016

Dan Kuester, Ryan T. Jacobs, Yao Ma, Jason Coder
A complete characterization of multiple-device wireless interactions must include data relatable to the electromagnetic field radiated by each device under test (DUT). If these field sources are separable in time or frequency, they can be demultiplexed
