Abstract
This work presents a longitudinal RF spectrum analysis using four sensing nodes deployed roughly near the corners of Notre Dame Stadium. The nodes collected IQ snapshots and stored power spectral density measurements over multiple days while scanning four frequency ranges used by Notre Dame TV and production operations. Data was collected both during an event and on no-event days to compare changes in spectrum activity under different stadium conditions. The analysis examines how spectrum occupancy, received power, and activity patterns vary across time, frequency range, and node location. The distributed placement of the nodes enables spatial comparison of observed signals and helps distinguish persistent activity from event-driven RF usage. Overall, this measurement campaign provides an initial characterization of the stadium RF environment and supports future work in distributed spectrum monitoring, activity detection, and event-aware RF spectrum analysis.
