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

Richard Candell
Background: Wireless technology has great appeals to many manufacturers, in this case industrial automation systems, which include process control, discrete manufacturing, safety systems, and building automation. Applying wireless sensing and control

Effects of Wireless Packet Loss in Industrial Process Control Systems

February 9, 2017
Author(s)
Yongkang Liu, Rick Candell, Nader Moayeri
Timely and reliable sensing and actuation control are essential in networked control. This depends on not only the precision/quality of the sensors and actuators used but also on how well the communications links between the field instruments and the
