Abstract

Abstract Summary

Overview

This study focuses on characterizing radio frequency electromagnetic field exposure levels to aid in developing greener and more sustainable wireless-empowered university campuses. A dual approach involving both environment-oriented and human-centric measurement methodologies was employed.

Methodology and Findings

• The study utilized 6-minute average measurements of electric and magnetic field values across various indoor and outdoor university spots using a broadband survey meter.
• Comparative analysis indicated that outdoor electric field levels in the sub 3 GHz band average around 1.67 V/m, which are significantly higher than those recorded indoors, such as in dormitories, labs, and classrooms.
• A detailed cumulative distribution function analysis was performed per wireless technology and environment, highlighting that Wi-Fi is the predominant source of electromagnetic exposure in indoor environments, surpassing emissions from 2G-5G mobile communications in outdoor settings.

Conclusion

The results of this study enable exposure-aware heterogeneous network planning and optimization specifically tailored for university campuses or similar environments. Further research could provide more insights into mitigating potential health risks associated with RF EMF exposure.
