Demultiplexing Spectrum-Sharing Field Sources with Distributed Field Probes

July 24, 2016
Author(s)
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

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.

An Long Term Evolution (LTE) Device-to-Device module for ns-3

June 14, 2016
Author(s)
Richard A. Rouil, Fernando Cintron, Aziza Ben Mosbah, Samantha Gamboa Quintiliani
In this paper, we provide an overview of the on-going implementation of a 3rd Generation Partnership Program (3GPP) Proximity Services (ProSe) module in ns-3 to enable the performance evaluation of device-to-device (D2D) discovery and communication in Long

On challenges in the uncertainty evaluation for time-dependent measurements

June 14, 2016
Author(s)
Sascha Eichstadt, Volker Wilkens, Andrew Dienstfrey, Paul D. Hale, Ben Hughes, Charles Jarvis
The measurement of quantities with time-dependent values is a common task in many areas of metrology. Although well established techniques are available for the analysis of such measurements, serious scientific challenges remain to be solved to enable

A Simulation Framework for Industrial Wireless Networks and Process Control Systems

May 6, 2016
Author(s)
Yongkang Liu, Richard Candell, Nader Moayeri, Kang B. Lee
Factory and process automation systems are increasingly employing information and communications technologies to facilitate data sharing and analysis in integrated control operations. Wireless connections provide flexible access to a variety of field

Configuring and Verifying Reverberation Chambers for Testing Cellular Wireless Devices

April 21, 2016
Author(s)
Catherine A. Remley, Jos N. Dortmans, Catherine Weldon, Thomas B. Meurs, Chih-Ming Wang, Christopher L. Holloway, Perry F. Wilson
Reverberation chambers provide a repeatable test environment for laboratory over-the-air testing and represent a viable solution for testing large-form-factor wireless devices. Such tests often involve “imperfect chamber” configurations in which the

Estimating and Reducing Uncertainty in Reverberation-Chamber Characterization at Millimeter-Wave Frequencies

April 20, 2016
Author(s)
Damir Senic, Catherine A. Remley, Chih-Ming Wang, Dylan F. Williams, Christopher L. Holloway, Diogo Ribeiro, Ansgar T. Kirk
This contribution provides techniques for accurately characterizing the measurement uncertainty due to chamber setup for total radiated power measurements at millimeter-wave frequencies. The setup is based on the reverberation chamber as a well-known

Public Safety Analytics R&D Roadmap

April 19, 2016
Author(s)
Tracy A. McElvaney, Ryan Felts, Marc Leh
The public safety community is in a period of great transition. Over the next 20 years, technology advancements will increase accessibility of data/video applications to public safety, and allow for the eventual migration of voice communications from
