A Simulation Platform to Study Inter-BAN Interference

December 2, 2013
Author(s)
Kamran Sayrafian, John G. Hagedorn, Martina Barbi, Judith E. Terrill, Mehdi Alasti
A Body Area Network (BAN) is a radio standard for wireless connectivity of wearable and implantable sensor nodes that are located inside or in proximity to the human body. Many applications of BANs (e.g. physiological monitoring) require reliable

Efficient Dithering Technique with Periodic Waveforms for RF Test and Characterization

October 7, 2013
Author(s)
Catherine A. Remley, Saeed Farsi, Bart Nauwelaers, Dominique Schreurs
A dithering technique based on ensemble averaging of waveforms is proposed. In the proposed method, instead of performing several measurements with different dithering additive noise, a single measurement of multiple periods of a sine-dithered periodic

INTER-BAN INTERFERENCE EVALUATION & MITIGATION: A PRELIMINARY STUDY

September 27, 2013
Author(s)
Kamran Sayrafian, Martina Barbi, Mehdi Alasti, Roberto Verdone
A Body Area Network (BAN) is a radio standard for wireless connectivity of wearable and implantable sensor nodes that are located inside or in proximity to the human body. Many applications of BANs (e.g. physiological monitoring) require reliable

Correlation Coefficient and Loading Effects for MIMO Antennas in a Reverberation Chamber

August 13, 2013
Author(s)
Nick Janssen, Kate Remley, Christopher L. Holloway, William F. Young
The correlation coefficient is a common metric for assessing the performance of an antenna for a multiple-input, multiple-out wireless device. In this paper, the effect of loading a reverberation chamber on the calculation of the correlation coefficient is

Evaluating Feedback Systems for Residential Building Energy Monitoring

August 10, 2013
Author(s)
Wenqi Guo, Tania Ullah, MengChu Zhou
Rising global energy demand, increasing electricity prices, and the limitation of natural resources have led to increased interest in energy monitoring of residential buildings. Much research has been done to examine the effect of energy use feedback to

On the Link Between Insertion Loss and Lower Bound of Efficiency

August 9, 2013
Author(s)
Levon Barsikyan, Jason Coder, Mark Golkowski, John M. Ladbury
We investigate the effect of chamber loss on the recently developed 2-port antenna model and the associated method of determining antenna efficiency. The loss in the reverberation chamber was controlled using microwave absorbing foam creating four

ITL Issues Guidelines for Managing the Security of Mobile Devices

July 15, 2013
Author(s)
Elizabeth B. Lennon
This ITL Bulletin announces the publication of NIST Special Publication 800-124 Revision 1, Guidelines for Managing the Security of Movile Devices in the Enterprise. The revised guidelines will assist organizations in managing the security of mobile
