Abstract

Overview

The advent of fifth-generation (5G) technology has introduced ultra-low latency and ultra-high dependability across various industries. Despite these advances, the use of higher frequency radiofrequency electromagnetic fields (RF-EMF) above 6 GHz in 5G mm-Wave base stations has raised significant health concerns due to potential risks associated with EMF exposure.

Methodology and Findings

This study focuses on measuring the maximum EMF exposure from a 5G mm-Wave base station, applying international standards for assessment and exposure limits.
Equipment used includes the R&S®TSMA6 scanner, R&S®ROMES4 software, and R&S®TSME30DC down converter, enhanced with GPS and an omnidirectional antenna.
A code selective method was applied to account for power fluctuations over time due to data traffic.
Findings confirm that maximum and average exposures of 5.71 V/m and 2.02 V/m respectively are within the safe exposure limits set by the ICNIRP standards.

Conclusion

Despite the compliance with safety standards, the study highlights inherent risks of RF-EMF exposure, necessitating ongoing research particularly in environments densely populated with mm-Wave base stations. It is essential to monitor these exposures continuously, especially with the increasing deployment of 5G technologies.
