Tagless identification and tracking with through-wall received signal strength-based radio tomographic imaging (RTI) allows emergency responders to learn where people are inside of a building before entering the building. Use of directional antennas in RTI nodes focuses RF power along the link line, improving system performance. However, antennas placed on a building's exterior wall can be detuned...

Road traffic congestion estimation is a critical function that affects both developed and developing countries alike. In this paper, we present Monitor as a novel RF-based traffic detection and identification system. Compared to the current approaches for traffic estimation, Monitor is low-cost, does not disrupt traffic during installation, works for non-laned traffic, and does not require active...
