This was a historic measurement campaign that Jet Zhu and a number of assisting students performed in Greenville, SC to test the effectiveness of E911 position location in an urban area using just received signal strength. Sponsored by Polaris Wireless, the results and algorithms have served as a template for numerous signal strength localization techniques.

This article analyzes the ranging errors in a new type of satellite ranging configuration: a system where a moving constellation of small satellites (e.g. cubesats) track other moving space-based targets. This work was sponsored by AFRL and performed in conjunction with Kirtland Air Force Base.

This recent journal article documents a multi-year collaborative effort with the University of Utah to perform topography on buildings by slapping sensor networks around the building perimeter. Measurement campaigns around Atlanta-area homes show how a custom-designed E-patch antenna can operate when placed against a variety of building materials. Using this antenna, the RF tomography accuracy improves significantly, identifying moving people within the building with 1-2 meters. The goal is to track emergency workers with a quick-to-deploy, ad-hoc wireless sensor network.
