This work introduces the ReMoRa (Reflection of Modulated Radio) concept using perfect pulses. The signaling scheme is a new method to squeeze information onto existing airwaves using an ultra-low-power re-scattering sensor.

2017 XXXIInd General Assembly and Scientific Symposium of the International Union of Radio Science (URSI GASS)
This recent conference publication describes how to measure and model the 3.5 GHz band for mobile communications. This particular band is interesting because mobile radio will have to share the spectrum with military radar systems, with mobile operators being required to “check out” their spectrum from a master database.

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.

This work describes how the ultra-low-powered Simon cipher can be implemented with a simple hash. This is a powerful technique for implementing encryption on computational- and power-limited platforms such as RFID tags.
