Using Absorption Cross Section to Predict Coherence Bandwidth and other Characteristics of a Reverberation Chamber Set-up for Wireless System Tests

October 3, 2016
Author(s)
Catherine A. Remley, Jos Dortmans, Damir Senic, Chih-Ming Wang, Christopher L. Holloway
We present a method to predict the coherence bandwidth, delay spread and power transfer function of a reverberation chamber set-up. The method is based on the absorption cross section of the absorbing material that is added to the chamber. With an S

Ultra-Dense Networks: Survey of State of the Art and Future Directions

August 4, 2016
Author(s)
Wei Yu, Hansong Xu, Hanlin Zhang, David W. Griffith, Nada T. Golmie
Abstract—Within the foreseeable future, the growing number of mobile devices, and their diversity, will challenge the current network architecture. Furthermore, users expect higher data rates, lower latency, lower packet drop rates, etc. in future wireless

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
