HF Proximity RFID Electromagnetic Emissions and Performance

November 16, 2008
Author(s)
Jeffrey R. Guerrieri, David R. Novotny, Catherine A. Remley, Michael H. Francis
We examined the emissions, and performance of commercial High-Frequency Radio Frequency Identification (HF RFID) systems to interrupt and eavesdropping. These proximity RFID systems are used in an increasing number of financial, identification, and access

HF RFID Electromagnetic Emissions and Performance

David R. Novotny, Jeffrey R. Guerrieri, Michael H. Francis, Catherine A. Remley
We examined the emissions, and susceptibility of commercial High-Frequency Radio Frequency Identification (HF proximity RFID) systems to interrupt and eavesdropping. RFID systems are being used in an increasing number of financial, identification, and

Use of Reverberation Chamber to Simulate the Power Delay Profile of a Wireless Environment

September 8, 2008
Author(s)
Christopher L. Holloway, E Genender, Catherine A. Remley, John M. Ladbury, Galen H. Koepke, H Garbe
Multipath propagation environment effects, such as frequency-selective fading, have a strong impact on the quality of the wireless channel. For example, multipath can impact bit error rate (BER) differently than Gaussian noise. For testing wireless devices

NIST Tests of the Wireless Environment in Automobile Manufacturing Facilities

September 1, 2008
Author(s)
Catherine A. Remley, Galen H. Koepke, Chriss A. Grosvenor, John M. Ladbury, Dennis G. Camell, Jason B. Coder, Robert Johnk
This report describes tests carried out by members of the NIST Electromagnetics Division to study the wireless environment in automotive manufacturing facilities. Testing was performed at three facilities during 2006 and 2007. We studied an assembly plant

Wireless Communications in Tunnels for Urban Search and Rescue Robots

August 18, 2008
Author(s)
Catherine A. Remley, George Hough, Galen H. Koepke, Dennis G. Camell, Robert Johnk, Chriss A. Grosvenor
We report on propagation tests carried out in a subterranean tunnel to support improved wireless communications for urban search and rescue robots. We describe single-frequency and ultrawideband channel-characterization tests that we conducted, as well as

Attenuation of Radio Wave Signals Coupled Into Twelve Large Building Structures

August 1, 2008
Author(s)
Christopher L. Holloway, William F. Young, Galen H. Koepke, Catherine A. Remley, Dennis G. Camell, Yann Becquet
In this report, we investigate radio communication problems faced by emergency responders (firefighters, police and emergency medical personnel) in disaster situations. A fundamental challenge to communications into and out of large buildings is the strong

Evaluation of Nonlinear Distortion in ADCs Using Multisines

June 15, 2008
Author(s)
Catherine A. Remley, Nuno Carvalho, Pedro Cruz
This paper characterizes nonlinear distortion in an analog-to-digital converter (ADC) when it is excited by representative communication signals having non-constant time-domain envelopes. The effect of subjecting the ADC to signals that present a range of

Multisine Signals for Wireless System Test and Design

June 13, 2008
Author(s)
Catherine A. Remley, Nuno Carvalho, Dominique Schreurs, Kevin Gard
We discuss the use of multisine test signals for system verification and model development in the laboratory. We highlight the utility of multisine excitation for test and verification of telecommunication systems, where nonlinear elements such as power

Mixed Analog-Digital Instrumentation for Software-Defined-Radio Characterization

June 5, 2008
Author(s)
Catherine A. Remley, Nuno Carvalho, Pedro Cruz, Kevin Gard
This paper presents a new type of analog-digital mixed-domain instrument that is specially tailored for software defined radio characterization. The instrument allows the utilization of analog instruments such as vector signal analyzers and network

Radio Communications for Emergency Responders in High-Multipath Outdoor Environments

June 2, 2008
Author(s)
Catherine A. Remley, Galen H. Koepke, Christopher L. Holloway, Chriss A. Grosvenor, Dennis G. Camell
We present measurement data to support technology and standards development for broadband, digitally modulated radio communications used by emergency responders. Measurements were carried out at an oil refinery, representing a class of high-multipath
