NIST Channel Sounder Overview and Channel Measurements in Manufacturing Facilities

November 8, 2017
Author(s)
Jeanne T. Quimby, Richard Candell, Catherine A. Remley, David R. Novotny, Joseph Diener, Peter B. Papazian, Alexandra Curtin, Galen H. Koepke
Manufacturers are increasingly choosing wireless platforms to replace wired ones due to their ease of installation, upgrade, and reconfigurability. Reliable and secure real-time performance of wireless platforms is technically challenging because wireless

Methods for Channel Sounder Measurement Verification

September 23, 2017
Author(s)
Kate Remley, Camillo Gentile, Alenka Zajic, Jeanne Quimby
We describe an activity of the 5G mmWave Channel Sounder Alliance to verify the hardware performance of channel sounders operating at mmWave frequencies. Such verification procedures are critical when attempting to compare data from sounders having

Gentile, Peter B. Papazian, Ruoyu Sun, Damir Senic, Jelena Senic, Matthew T. Simons, Maria G. Becker, Dylan F. Williams, Richard A. Chamberlin, Jerome G. Cheron, Ari D. Feldman, Paul D. Hale, Mohit S. Mujumdar, Nada T. Golmie
National Metrology Institutes (NMIs) around the world are charged with supporting industry through improved measurement science and by providing a traceability path to fundamental physical standards. Mobile wireless communications have become a ubiquitous

Channel Sounder Measurement Verification and Uncertainty

June 2, 2017
Author(s)
Catherine A. Remley, Jeanne T. Quimby, Paul D. Hale, Dylan F. Williams, Jeffrey A. Jargon, Rodney W. Leonhardt
This presentation describes channel-sounder measurement verification procedures including options such as comparing measurements to theory, conducted tests of a known, simulated-channel artifact, direct over-the-air comparison to a vector network analyzer

Industrial Wireless Systems: Radio Propagation Measurements

January 30, 2017
Author(s)
Richard Candell, Catherine A. Remley, Jeanne T. Quimby, David R. Novotny, Alexandra Curtin, Peter B. Papazian, Galen H. Koepke, Joseph Diener, Mohamed T. Hany
Radio frequency (RF) propagation measurements were conducted at three facilities representing a cross-section of different classes of industrial environments. Selected sites included a multi-acre transmission assembly factory typical of the automotive

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

Variability of Sounder Measurements in Manufacturing Facilities

June 27, 2016
Author(s)
Jeanne Quimby, Alexandra Curtin, David R. Novotny, Chih-Ming Wang, Rick Candell
Uncertainties in the linear regression fit of Path Loss are derived from variability in position. These uncertainties are used to determine the required positional accuracy for channel sounder measurements.
