Abstract

Abstract Summary

Overview

The study investigates the effects of electromagnetic waves in office settings due to prevalent usage of wireless and cellular systems like Wi-Fi, 3G, and 4G networks. The focus revolves around measuring radiation levels in an office environment accommodating 4-5 individuals using these technologies.

Findings

  • Radiation levels with single Wi-Fi user can exceed the reference levels for the entire bandwidth.
  • With three users utilizing 3G/4G networks, radiation levels surmount those of Wi-Fi scenarios, with 4G levels being approximately 10% higher than Wi-Fi.
  • Detailed measurements using a NARDA SRM-3000 inside a medium-sized office showed significant increases in electromagnetic field (E-field) footprints with increasing number of active device users.
  • The study highlighted that even with increased activity, such as downloading or uploading data, the measured E-field values remained significantly lower (about 66 times lower) than the non-ionizing radiation safety values for public exposure.

Conclusion

This study strengthens understanding of electromagnetic radiation exposure in workplace environments. Although the E-field values were lower than safety thresholds, the potential for over-exposure in scenarios with multiple device users exists, emphasizing the need for continual monitoring and adherence to safety standards.
