Measurements to Support Public Safety Communications: Attenuation and Variability of 750 MHz Radio Wave Signals in Four Large Building Structures: NIST Technical Note 1552

August 7, 2009
Author(s)
William F. Young, Kate Remley, John M. Ladbury, Christopher L. Holloway, Chriss A. Grosvenor, Galen H. Koepke, Sander Floris, Wouter Numan, Andrea Garuti
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 radio communications into and out of large buildings is the

Standard Radio CommunicationTest Method for Mobile Ground Robots

March 31, 2009
Author(s)
Kate Remley, Galen H. Koepke
This paper describes a proposed standard method for conducting a performance evaluation of wireless communications links used for the control and telemetry systems on mobile ground robots. Range performance metrics are determined under open line-of-sight

Using Reverberation Chambers to Determine the Shielding Effectiveness of Physically Small, Electrically Large Enclosures/Cavities

November 20, 2008
Author(s)
Christopher L. Holloway, David A. Hill, Marco Sandroni, John M. Ladbury, Jason B. Coder, Galen H. Koepke, Andrew C. Marvin
With the proliferation of small electric devices in recent years, along with various other applications, there is a growing need to test and determine the shielding properties or shielding effectiveness (SE) of physically small (but electrically large)

Source Stirring Technique for Reverberation Chambers; Experimental Investigation

September 8, 2008
Author(s)
Galen H. Koepke, Christopher L. Holloway, John M. Ladbury, David A. Hill, Valter Primiani, Paola Russo, Carlo Monteverde
The paper shows the source stirring technique from an experimental point of view. This technique exhibits good statistics for S21. The results illustrate that the field in the cavity has very similar characteristics to the field in a reverberation chamber

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

Electromagnetic Airframe Penetration Measurements of a Beechcraft Premier IA

August 1, 2008
Author(s)
Chriss A. Grosvenor, David R. Novotny, Dennis G. Camell, Galen H. Koepke, Robert Johnk
The National Institute of Standards and Technology has recently completed shielding effectiveness/penetration studies on three different aircraft types for the Federal Aviation Administration. The studies are used to understand the cavity coupling
