Demonstration of Safe Electromagnetic Radiation Emitted by 5G Active Antenna Systems

Abstract

Overview

The deployment of 5G technologies holds significant promise for both society and the economy, leveraging key advances such as higher frequency operation, beamforming, and small-cell configurations to deliver unprecedented throughput and seamless user connectivity. However, limited knowledge regarding these technologies has led to widespread public concern surrounding the potential health risks caused by electromagnetic radiation (EMF) exposure linked to 5G networks.

Findings

• Standardization bodies have developed EMF emission limits based on current measurement methodologies, yet these may yield inaccurate results when applied to the dynamic characteristics of 5G—such as beam steering, network densification, and time-division duplexing.
• The authors conducted experimental studies with 5G base stations employing Active Antenna Systems (AAS) to measure radiation emitted during beam-based transmissions.
• Shortcomings of present EMF measurement methods for 5G were identified, as well as several outstanding questions relevant to public health impact and technical accuracy.
• User-specific downlink beamforming was shown to improve performance and notably decrease radiation exposure in the vicinity of the intended user, reducing EMF health risks locally.
• Conversely, weak reception conditions during uplink transmission can cause considerably elevated radiation levels near user equipment, which may heighten potential biological effects from EMF exposure.

Conclusion

These findings clarify misconceptions about 5G-related EMF radiation risks while underlining the direct relationship between specific 5G operating conditions and changes in EMF exposure. The study provides practical guidelines for improving measurement methodologies by accounting for the spatial and temporal dynamics of 5G emissions, which is crucial to public health and regulatory standards.
