Lundrigan will present on how to boot-STRAP WiFi authentication
Fri, 11 May 2018 --- In deployments of WiFi devices for smart home applications, the time required for passing home WiFi authentication information to each device is long and is proportional to the number of sensors being deployed. Deployers could save significant time and avoid problems with Philip Lundrigan's new secure transfer of association protocol" (STRAP), which sends authentication information to all devices simultaneously in a secure and novel manner. He will present STRAP at the 27th International Conference on Computer Communications and Networks (ICCCN 2018) on 30 July 2018 in Hangzhou China.
Anh Luong Presents and Wins in Porto
Wed, 11 Apr 2018 --- SPAN Lab graduate Dr. Anh Luong presented two papers at the 2018 ACM / IEEE International Conference on Information Processing in Sensor Networks in Porto, Portugal. One was on his PhD work, titled A Stitch in Time and Frequency Synchronization Saves Bandwidth". The second was on his postdoctoral work at CMU, called "Charm: Exploiting Geographical Diversity Through Coherent Combining in Low-Power Wide-Area Networks", won the IPSN 2018 Best Paper Award! Congrats to Anh!
Chris Anderson Presents at the U
Tue, 23 Jan 2018 --- Prof. Chris R. Anderson will present a seminar titled "Integrated Terrain and Clutter Propagation Modeling for 1.7 GHz Spectrum-sharing" on Friday 26 January 2018, from 3:05 - 3:55 PM in WEB 1230. His talk addresses radio propagation measurements and models for the coexistence of military communications systems and future commercial LTE operators in the 1695-2180 MHz band. Existing models were highly conservative in an effort to ensure protection of DoD systems. Chris' work is an attempt to provide more accurate models so that this band can be fully utilized.

Utah Modified Dylos Sensor Wins Best in Session Award
Tue, 02 Jun 2015 --- Congratulations to Kyeong T. Min, whose poster was awarded "Best In Session" at the 2015 American Industrial Hygiene Association Conference & Expo, held here in Salt Lake City, Utah. Kyeong designed and built the "Utah Modified Dylos Sensor", an air quality sensing server and Android app which form a unified sensing, wireless interface, database, and user interface for use in human subjects air quality sensing research. The poster is titled "Development of a low-cost environmental sensor with remote real-time monitoring of indoor particulate, temperature and relative humidity", and its authors are Ben S Cryder, Darrah K Sleeth, Yue Zhang, Kyeong T Min, Chong Zhang, and Scott C Collingwood.
NSF Grant Awarded to Investigate the Science of Temporal Fading
Tue, 10 Jun 2014 --- The NSF has funded our research project "Advanced Radio Frequency (RF)-based Environmental Monitoring Systems" to be performed collaboratively at Georgia Tech and the University of Utah. Prof. Neal Patwari and the SPAN lab will conduct the research at the University of Utah, and Prof. Gregory D. Durgin and the Propagation Lab will conduct the research at Georgia Tech. The award is an investigation in the science of temporal fading as it is useful for new radio frequency (RF) environmental monitoring (REM) systems. Research in this project considers temporal fading and seeks to establish how it is affected by the movements of people in the environment so that it can be exploited for environmental monitoring.
Best Paper Award at IPSN 2014
Wed, 16 Apr 2014 --- Congratulations to Ossi Kaltiokallio, Hüseyin Yigitler, Riku Jäntti, and Neal Patwari! Their paper, "Catch a Breath: Non-invasive Respiration Rate Monitoring via Wireless Communication", was awarded the Best Paper Award at the 13th IEEE/ACM International Conference on Information Processing in Sensor Networks (IPSN 2014), held April 15-17 in Berlin, Germany. Ossi Kaltiokallio, Hüseyin Yigitler, and Riku Jäntti are affiliated with Aalto University in Espoo, Finland. Ossi was a visiting researcher in the SPAN lab in 2012.

Brad Mager presents at PIMRC 2013 on Fall Detection
Thu, 15 Aug 2013 --- Brad Mager presented his paper, "Fall Detection Using RF Sensor Networks", at the 24th Annual IEEE Symposium on Personal, Indoor, and Mobile Communications Conference (PIMRC '13) in London, on Tuesday September 3. His paper is the first presented paper in the "Event Sensing and Localization" Session at 11am - 12:40pm. His paper is co-authored by Neal Patwari and Maurizio Bocca.
Merrick McCracken presents at SECON 2013
Thu, 15 Aug 2013 --- Merrick McCracken presents his paper, Joint ultra-wideband and signal strength-based through-building tracking for tactical operations, at the 2013 IEEE Intl. Conf. on Sensing, Communications, and Networking, on Wednesday, June 26, in New Orleans. His paper, co-authored by Maurizio Bocca and Neal Patwari, explores combining ultra-wideband impulse radar with radio tomography in order to achieve accurate localization without having sensors on all sides of an area to be covered. The idea is particularly motivated by emergency response applications.
Congratulations to Brad Mager!
Mon, 15 Apr 2013 --- Brad Mager had a great night at the ECE Technical Open House Award Banquet. He was awarded "Outstanding Computer Engineering Student", and also awarded one of six "Best Presentation" awards for his talk on his senior thesis, "Fall Detection Using RF Sensor Networks". His talk was also mentioned by the keynote speaker and distinguished alumnus award winner Dr. John Sutherland as an example of useful research into the "internet of things". Congrats to Brad on his awards!
