Evaluation of Exposure to Radiofrequency Electromagnetic Fields from Smart Utility Meters operating at 868 MHz

Abstract

Overview

The study focuses on measuring power density and duty factor values around smart utility meters operating at 868 MHz under controlled laboratory conditions.

Findings

• The peak 6-minute averaged exposure was recorded at 0.1 mWm^-2, significantly lower than 0.0024% of the 1998 ICNIRP public reference level.
• Duty factors for these measurements were found to be less than 2.8%, indicating minimal duty cycle operation.
• Exposure levels from devices operating at 868 MHz were generally lower or comparable to those at 2.4 GHz, used by similar device types.

Conclusion

This assessment highlights minimal exposure from certain smart meters, aligning with existing safety standards but underlines the critical need for continued surveillance and strict adherence to these guidelines to safeguard public health against potential EMF risks.
