Patent for Robust Wi-Fi Environment Sensing Technology
ECE Associate Professor Francesco Restuccia was awarded a patent for “System and method for sensing an environment.”
Abstract Source: USPTO
A system and corresponding method sense an environment. The system comprises a wireless transmitter device that transmits a wireless signal through the environment. The system further comprises a plurality of wireless receivers that each 1) receive the wireless signal at a distinct location within the environment via at least one respective antenna and 2) generate a channel state information (CSI) packet indicating a state of a wireless communications channel associated with the wireless signal. The system still further comprises a computing device and classifier. The computing device processes the CSI packets from the plurality of wireless receivers and generates a CSI dataset as a function of the CSI packets processed. The classifier determines at least one class for the CSI dataset. The system and corresponding method improve robustness of sensing operations, such as robustness of Wi-Fi sensing operations to noise and interference.
