Spatial and temporal assessment of radiofrequency electromagnetic fields emitted by smart meters and smart meter banks in urban environments

Abstract

Overview

This paper focuses on the analysis of radiofrequency (RF) electromagnetic fields (EMF) in the proximity of single and multiple advanced metering infrastructure (AMI) smart meters in urban settings.

Findings

• A methodology is introduced to evaluate spatiotemporal RF-EMF exposure from AMI smart meters.
• Field measurements encompass assessments in a testing facility and five urban sites, evaluating worst-case electric-field levels at varying distances.
• Maximum field levels noted at 0.3 meters ranged between 10-13 V/m for single meters and 18-38 V/m for meter banks extending up to 81 meters.
• Duty cycles, indicating the transmission time of AMI meters, showed minimal percentages, ranging from 0.01% up to 13%, demonstrating sporadic emissions.
• Constructed statistical models predict electric-field strengths for any AMI meter configuration, ensuring compliance with safety standards.
• All measured exposure levels maintained significant margins below the prescribed limits of ICNIRP, FCC, and IEEE.

Conclusion

The analysis confirms that the EMF emissions from smart meters, even in dense configurations, are within international safety guidelines, yet it is acknowledged that continuous monitoring and regulation are essential to address potential health risks associated with RF-EMF exposures.
