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.
