Channel Characterization and Delay Optimization for Industrial Wireless Control Systems

March 4, 2019
Author(s)
Xiaolin Jiang, Zhibo Pang, Rick Candell, Dacfey Dzung, Michele Luvisotto, Carlo Fischione
Wireless communication is gaining popularity in industry for its simple deployment, mobility and low cost. Ultra low latency and high reliability requirements of mission critical industrial applications are highly demanding for wireless communication, and

Lets Keep Women in Microwaves

March 1, 2019
Author(s)
Catherine A. Remley
This is a column for the "Women in Microwaves" affinity group of the IEEE Microwave Theory and Techniques Society, to be published in IEEE Microwave Magazine. The column discusses the well documented effect that after ten years or so into a science

Methodology for Multipath-Component Tracking in Millimeter-Wave Channel Modeling

March 1, 2019
Author(s)
Chiehping Lai, Roy Sun, Camillo Gentile, Peter B. Papazian, Jian Wang, Jelena Senic
In this paper, we describe an extensive channel-measurement campaign - including 325 unique transmitter-receiver configurations - conducted in a lecture room with our 3D double- directional 60-GHz channel sounder. The receiver was mounted on a mobile robot

Portable Verification Artifact for Millimeter-Wave-Frequency Channel Sounders

March 1, 2019
Author(s)
Jos N. Dortmans, Jeanne Quimby, Kate Remley, Dylan Williams, Jelena Senic, Roy Sun, Peter B. Papazian
We develop a portable artifact for the conducted verification of millimeter-wave-frequency channel sounders. The artifact is first characterized with a vector network analyzer, providing a high-dynamic range, traceable measurement and complete uncertainty

Mobile Device Security: Cloud and Hybrid Builds

February 21, 2019
Author(s)
Christopher J. Brown, Spike E. Dog, Sallie P. Edwards, Neil C. McNab, Matt Steele, Joshua M. Franklin
This document proposes a reference design on how to architect enterprise-class protection for mobile devices accessing corporate resources. The example solutions presented here can be used by any organization implementing an enterprise mobility management

Performance Assessment of Smart Meter Traffic over LTE Network Using SDR Testbed

February 18, 2019
Author(s)
Amirshahram Hematian, Wei Yu, David W. Griffith, Nada T. Golmie
In the smart grid, a variety of smart meters will be deployed to support diverse services, such as energy distribution management, grid monitoring and management, and the integration of renewable energy resources. On the power distribution side, regular

Impedance tuning with photoconductors to 40 GHz

January 22, 2019
Author(s)
Jasper A. Drisko, Ari D. Feldman, Franklyn J. Quinlan, James C. Booth, Nathan D. Orloff, Christian J. Long
Light has been widely used to control a variety of microwave devices, including switches, antennas, and detectors. Here, we present a photoconductive device integrated into a coplanar waveguide to tune complex impedances at microwave frequencies with

A User Application-Based Access Point Selection Algorithm for Dense WLANs

January 16, 2019
Author(s)
Munsuk Kim, Ye Na Kim, Sukyoung Lee, Nada T. Golmie, SeungSeob Lee
The current commercial access point (AP) selection schemes are mostly based on signal strength, but perform poorly in many situations because they ignore the actual load distributions among the APs. To address this shortcoming, a number of alternative

Efficient MU-MIMO Beamforming Protocol for IEEE 802.11ay WLANs

January 1, 2019
Author(s)
Munsuk Kim, Tanguy Ropitault, SuKyoung Lee, Nada T. Golmie
IEEE 802.11ay supports multi-user multiple-input-multiple-output (MU-MIMO). However, the MU- MIMO BFT (Beamforming Training) is a time-consuming process to find appropriate directional antenna patterns, and inefficient BFT results in a long training time

Impact of Measurement Points Distribution on the Parameters of UWB Implant Channel Model

December 20, 2018
Author(s)
Kamran Sayrafian, Sofia Perez-Simbor, Katjana Krhac, Concepcion GarciaPardo, Dina Simunic, Narcis Cardona
Sophisticated medical implants that allow vital information delivery to/from the human body are opening the door to novel approaches in diagnosis and/or therapy of various health related issues. Ultra-Wide Band (UWB) technology is gaining the attention of
