Dimensioning Wireless Use Cases in Industrial Internet of Things

June 12, 2018
Author(s)
Yongkang Liu, Rick Candell, Mohamed Hany, Lotfi Benmohamed
Industrial wireless is becoming increasingly needed in the Industrial Internet of Things (IIoT) for carrying mission-critical data to leverage the visibility, control, and safety of industrial environments. In this paper we propose a framework that

Guide to Industrial Wireless Systems Deployments

May 21, 2018
Author(s)
Richard Candell, Mohamed T. Hany, Kang B. Lee, Yongkang Liu, Jeanne T. Quimby, Catherine A. Remley
This document is intended to be a practical guide used by engineers and managers facilitating them to go through the process of defining the objectives of their wireless systems and examining the environments where the wireless systems are to be deployed

Quasi-Deterministic-Channel-Propagation Model for a Data Center at 60 GHz

April 30, 2018
Author(s)
Camillo Gentile, Peter B. Papazian, Roy Sun, Jelena Senic, Jian Wang
We describe a measurement campaign conducted in a data center, a unique environment in which transceivers are positioned above the server racks. A total of 80 channel acquisitions, including small-scale measurements, were recorded using our 3D double

Fading due to static and dynamic features in a factory environment on wireless channels

April 20, 2018
Author(s)
Alexandra Curtin, David R. Novotny, Richard Candell, Galen H. Koepke, Peter B. Papazian, Jeanne T. Quimby, Catherine A. Remley
Channel sounding of dense or complex environments such as industrial or factory spaces is an important piece to the puzzle of increasing the deployment of current and next-generation wireless technologies. The deployment of machine--to-machine or vehicle

Bringing Precision to 5G Test: Activities in the U.S.

April 9, 2018
Author(s)
Catherine A. Remley, Maria G. Becker
(Workshop Abstract) The next generation (5G) network won’t just deliver much faster connection and higher data capacity. It also promises to provide reliable connectivity, low energy consumption, and connecting billions of people and trillions of things

Spatial Channels for Wireless Over-the-Air Measurements in Reverberation Chambers

April 9, 2018
Author(s)
Maria G. Becker, Rob Horansky, Damir Senic, Vincent T. Neylon, Kate Remley
NIST is developing a hybrid test chamber for over-the-air characterization of the next generation of wireless devices in spatial channel environments. By combining features of both reverberation and anechoic chambers, the hybrid chamber will produce

The New Large Antenna Positioning System for Over-The-Air Testing at the National Institute of Standards and Technology

April 8, 2018
Author(s)
Jeffrey R. Guerrieri, David R. Novotny, Josh Gordon, Alexandra Curtin, Michael S. Allman, Kim Hassett, Quang Ton
This paper introduces the new Large Antenna Positioning System (LAPS) at the National Institute of Standards and Technology (NIST). For the last eight years NIST has been pioneering the use of robotics for antenna measurements. Starting with the

Cooperative Vehicular Networking: A Survey

March 8, 2018
Author(s)
Hamid Gharavi
With the remarkable progress of cooperative communication technology in recent years, its transformation to vehicular networking is gaining momentum. Such a transformation has brought a new research challenge in facing the realization of cooperative

Unsupervised Clustering for Millimeter-Wave Channel Propagation Modeling

February 11, 2018
Author(s)
Jian Wang, Camillo Gentile, Jelena Senic, Roy Sun, Peter B. Papazian
We have designed and assembled millimeter-wave channel sounders at 28, 60, and 83 GHz. They can measure the three-dimensional (azimuth and elevation) double-directional angle (angle-of- departure and angle-of-arrival) of channel multipath components as
