Design of a Mobile, Low-Cost Spectrum Analyzer
Electrical and Computer Engineering
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.
