Comprehensive Measurement-Based Assessment of Downlink RF-EMF Exposure in Urban Environments: Multi-Method Analysis and Intercomparison.
This study reports a measurement-based assessment of outdoor downlink RF-EMF exposure in a French city using drive testing, spot measurements, and a streetlamp-mounted sensor network. The authors report good agreement across methods and correlations between smoothed drive-test data, spot measurements, and base station antenna density. They also report that 5G NR spot measurements with traffic-attracting downloads show beamforming-related changes in exposure, and that sensor data vary with distance to the nearest base station antenna.
Key points
- Three measurement approaches (drive test, spot measurements, and a sensor network) were used to assess urban RF-EMF exposure.
- The abstract reports good agreement in exposure levels across the three measurement systems.
- A distance-based moving average was applied to drive-test data, with window size optimized using a Kolmogorov-Smirnov test.
- Smoothed drive-test results reportedly correlated with nearby spot measurements and with base station antenna density.
- 5G NR spot measurements with and without traffic-attracting downloads suggest beamforming can affect exposure levels in 5G bands.
- Kriging-based exposure maps built from spot measurements were compared with drive-test data.
- Sensor-network temporal variations were analyzed versus distance to the nearest base station antenna, reporting an inverse proportional relationship.
