Wireless Activities in the 2 GHz Radio Bands in Industrial Plants

September 27, 2017
Author(s)
Yongkang Liu, Nader Moayeri
Wireless connections are becoming popular in industrial environments that increasingly carry sensing and actuation data over the air. In industrial plants, activities of legacy wireless systems have shaped the channel usage in the radio spectrum bands for

Methods for Channel Sounder Measurement Verification

September 23, 2017
Author(s)
Kate Remley, Camillo Gentile, Alenka Zajic, Jeanne Quimby
We describe an activity of the 5G mmWave Channel Sounder Alliance to verify the hardware performance of channel sounders operating at mmWave frequencies. Such verification procedures are critical when attempting to compare data from sounders having

Black Box Measurement of System Noise in Integrated Wireless Receivers

September 13, 2017
Author(s)
Daniel G. Kuester, Duncan A. McGillivray, Sheryl M. Genco, Dazhen Gu
Tightly-integrated antennas and inaccessible radio frequency (RF) outputs are common barriers to measuring system noise in integrated wireless receive systems. We propose a solution centered on locating "SNR isoresponses" --- processed receiver outputs

Multiple Sources in a Reverberant Environment: The "Cocktail Party Effect"

September 3, 2017
Author(s)
Perry F. Wilson
This electronic Acoustics and electromagnetics have a number of parallels based on similar equations describing propagation, reflection, and reverberation. This paper considers one example, the "cocktail party effect", that describes speech comprehension

3.5 GHz Environmental Sensing Capability Detection Thresholds and Deployment

September 1, 2017
Author(s)
Thao Nguyen, Anirudha Sahoo, Michael R. Souryal, Timothy Hall
Spectrum sharing in the 3.5~GHz band between commercial and government users along U.S. coastal areas depends on an Environmental Sensing Capability (ESC)---that is, a network of radio frequency sensors and a decision system---to detect the presence of

3.5 GHz Radar Waveform Capture at Fort Story

August 4, 2017
Author(s)
Paul D. Hale, Jeffrey A. Jargon, Peter J. Jeavons, Michael R. Souryal, Adam J. Wunderlich, Mark Lofquist
We describe measurements to create a library of high-fidelity waveforms of federal incumbent radar signals currently operating in the 3550 MHz – 3650 MHz (“3.5 GHz”) band. In this second phase of assembling the library, measurements were collected at Fort

Real-Time Scheduling for Wireless Networks with Random Deadlines

July 26, 2017
Author(s)
Mohamed Hany, Nader Moayeri
The use of wireless communications in industrial environments is motivated by the flexibility that wireless networks provide and their cost-efficient setup and maintenance. Various wireless technologies have been introduced to satisfy the strict industrial

Updated NIST Guidance for Bluetooth Security

July 26, 2017
Author(s)
Lidong Chen, Larry Feldman, Gregory A. Witte
This bulletin summarizes the information in NIST SP 800-121, Revision 2: Guide to Bluetooth Security which provides information on the security capabilities of Bluetooth and provides recommendations to organizations employing Bluetooth wireless

Autonomous Relocation Strategies for Cells on Wheels in Public Safety Networks

July 20, 2017
Author(s)
Kamran Sayrafian, Ladan Rabieekenari
Lack of network availability or limited access to communication services are among the challenges that public safety officials and first responders could face during disasters or emergency scenarios. Networking infrastructure can partially (or sometimes
