Wireless Network Design for Emerging IIoT Applications: Reference Framework and Use Cases

April 16, 2019
Author(s)
Yongkang Liu, Mohamed T. Hany, Kang B. Lee, Lotfi Benmohamed, Richard Candell
In this paper we propose a framework that allows a designer to assess various physical and cyber factors involved in determining the performance of a wireless use case as well as evaluate their performance impacts in search for a design that leads to an

Indoor Localization Accuracy of Major Smartphone Location Apps

April 14, 2019
Author(s)
Nader Moayeri, Chang Li, Lu Shi
NIST carried out comprehensive testing in five large buildings to evaluate the accuracy of Fused Location Provider (FLP) Application Programming Interface (API) running on Android phones with that of Core Location Framework running on iPhones. The testing

Optimal Dynamic Spectrum Access Scheme for Utilizing White Space in LTE Systems

April 15, 2019
Author(s)
Anirudha Sahoo, Timothy Hall, Robert C. Hagwood
In this study, we design and implement an algorithm for optimal dynamic spectrum access (DSA) in a shared spectrum system where the primary user (PU) is a Long Term Evolution (LTE) system. The cumulative hazard function from survival analysis is used to

A New Perspective on an Old Problem: Scattering by a Perfect Electric Conductor

April 14, 2019
Author(s)
Alexey J. Yuffa, Johannes Markkanen, Qiang Sun, Evert Klaseboer, Derek Y. Chan
We explore several different singular surface integral equation formulations. These formulations are specifically designed for time-harmonic scattering by a perfect electric conductor and are obtained by choosing non-conventional boundary unknowns.

System Distortion Model for the Cross-Validation of Millimeter-Wave Channel Sounders

March 31, 2019
Author(s)
Camillo Gentile, Andreas Molisch, Jack Chuang, Anuraag Bodi, Anmol Bhardwaj, Ozgur Ozdemir, Ismail Guvenc, Zihang Cheng, Thomas Choi, Robert Mueller
Because millimeter-wave directional channel measurements are time-consuming and expensive to collect, there is considerable interest in combining measurement data obtained with different channel sounders in order to yield more comprehensive datasets. The

Interlaboratory Millimeter-Wave Channel Sounder Verification

March 30, 2019
Author(s)
Jeanne Quimby, David G. Michelson, Mustapha Bennai, Kate Remley, Joshua Kast, Alec Weiss
The channel sounder verification program within the National Institute of Standards and Technology-coordinated 5G mmWave Channel Model Alliance aims to place channel sounders on a sound metrological foundation by using well-established laboratory
