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

2015 Location-Based Services R&D Summit Report

January 30, 2017
Author(s)
Harris Feldman, Adam H. Danielson
The Public Safety Communications Research Program (PSCR) convened over 80 stakeholders at the National Institute of Standards and Technology (NIST) Boulder, CO campus to build on the findings presented in the 2015 Location-Based Services (LBS) Summit- held

Industrial Wireless Systems: Radio Propagation Measurements

January 30, 2017
Author(s)
Richard Candell, Catherine A. Remley, Jeanne T. Quimby, David R. Novotny, Alexandra Curtin, Peter B. Papazian, Galen H. Koepke, Joseph Diener, Mohamed T. Hany
Radio frequency (RF) propagation measurements were conducted at three facilities representing a cross-section of different classes of industrial environments. Selected sites included a multi-acre transmission assembly factory typical of the automotive

Impact of timing on the Proximity Services (ProSe) synchronization function

January 8, 2017
Author(s)
Samantha Gamboa Quintiliani, Fernando Cintron, David W. Griffith, Richard A. Rouil
Long Term Evolution Advanced (LTE-A) introduces a new feature called Proximity Services (ProSe), which enables device-to-device (D2D) communication between User Equipment (UE) and the capability to operate out-of-network. In order to establish a D2D

Using RTS/CTS to Enhance the Performance of IEEE 802.15.6 CSMA/CA

December 22, 2016
Author(s)
Kamran Sayrafian, Martina Barbi, Mehdi Alasti
IEEE 802.15.6 is a radio interface standard for a wireless connectivity of wearable and implantable sensors and actuators located inside or in close proximity to the human body i.e. Body Area Network (BAN). Medical applications requirements impose

Towards Energy Efficiency in Ultra Dense Networks

December 11, 2016
Author(s)
Wei Yu, Hansong Xu, Amirshahram Hematian, David W. Griffith, Nada T. Golmie
The Ultra Dense Network (UDN), as a key enabler for future wireless networks (such as 5G), is comprised of a massive number of small cells in the network. Nonetheless, energy consumption will be non-negligible when a large number of small- cell Base

Measurement of Wireless Devices in Reverberation Chambers

December 7, 2016
Author(s)
Catherine A. Remley
When the antenna is integrated into the body of a wireless device, as it is for cell phones and many other portable devices, performance testing is typically done under free-field conditions. In this overview presentation, we will discuss free-field

Distributed Control and Communications for Grid Systems

December 5, 2016
Author(s)
Hamid Gharavi
A major problem of the grid system is identifying the source of abnormal behaviors. It is particularly important to identify the areas in which the grid system suffers from power deficiencies due to fault or voltage instability. Phasor Measurement Units

Optimizing the UE Transmission Probability for D2D Direct Discovery

December 5, 2016
Author(s)
David W. Griffith, Fiona Z. Lyons
We develop an analytical model to examine the effect of the transmission probability on type~1 direct discovery in Device-to-Device (D2D) Long Term Evolution (LTE) networks. The model gives us the distribution of the time for a User Equipment (UE) to

Pathloss Models for Indoor Hotspot Deployment at 83.5 GHz

December 3, 2016
Author(s)
Camillo Gentile, Jelena Senic, Peter B. Papazian, Jae-Kark Choi, Kate Remley
Conventional pathloss models are based on the received power from an omnidirectional antenna. Millimeter-wave receivers, conversely, will feature highly directional antennas that can be steered towards the angle with maximum power, exploiting their high

BLER Performance Evaluation of LTE Device-to-Device Communications

November 9, 2016
Author(s)
Jian Wang, Richard A. Rouil
Long-Term Evolution (LTE) supporting Device-to-Device (D2D) communication is a feature introduced in 3rd Generation Partnership Project (3GPP) release 12. D2D communication is critical in public safety applications, which enables communication among first

A Tetherless, Absolute-Time Channel Sounder, Processing, and Results for a Complex Environment

November 4, 2016
Author(s)
David R. Novotny, Alexandra E. Curtin, Catherine A. Remley, Peter B. Papazian, Jeanne T. Quimby, Richard Candell
we present a channel sounder that can operate without a tether and still maintain an absolute time reference between the source and receiver. Based on a sliding correlator, with synchronized rubidium clocks to generate phase references for the up- and down

A Clustering-Based Device-to-Device Communication to Support Diverse Applications

October 13, 2016
Author(s)
Amirshahram Hematian, Wei Yu, Chao Lu, David W. Griffith, Nada T. Golmie
The expanding coverage and capacity of cellular networks through broadband wireless infrastructure has limitations in accommodating the expanding strain and capacity required by diverse applications (public safety, smart grid, transportation, healthcare

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
