New technology that detects the presence of cars at intersections utilizes wireless radios. Prototypes of this technology are sensitive to interference. Before these prototypes can be evaluated, radio activity in test sites must be screened to ensure that the devices will be able to operate properly. Our team designed a low-cost, battery-powered spectrum analyzer capable to monitor radio activity around intersections in the 850 - 950 MHz band. The spectrum analyzer uses a software-defined radio controlled by a Raspberry Pi to measure signal power in this frequency band and log measurements as a function of time.

Biographical Information about Author(s)

Jacob Harrison is a senior Computer Engineering major at Valparaiso University. He started working with Dr. White's "!WIRED" laboratory in 2017 to research ways to improve the performance of software defined radios in satellite ground stations for the community-driven SatNOGs project. He will attend the University of Florida in the fall of 2019 to begin work toward a PhD in hardware/software security.
