Abstract

Overview

The increased prevalence of 5G technology necessitates an updated methodology for measuring electromagnetic fields. This study discusses the inadequacies of traditional tools like spectrum analyzers for accurately capturing the dynamics of modern telecommunications technologies, which use high power in short bursts across a wide band. In response, software-defined radios (SDRs) offer a novel, cost-effective solution.

Methodology

New measurement techniques employing SDRs are explored to enhance spatial density and accuracy in the assessment of electromagnetic field strength in 5G networks. The paper emphasizes the importance of calibrating SDRs to accurately measure and analyze the RF power emitted by 5G systems.

Findings

• The research confirms that the average electric field exposure in 5G networks remains below the harmful threshold, generally well under 1 V/m.
• Peak exposure from user equipment can reach up to 40.82 V/m, indicating potential points of high exposure despite the average values being low.
• The measurements validate that a low-cost SDR system can be effectively used for accurate field measurements in 5G networks.

Conclusion

This study outlines significant advancements in measuring techniques that could influence how electromagnetic field exposure is evaluated, particularly in the context of expanding 5G technology. It strikes a balance between addressing public health concerns and technological advancements in telecommunications.
