Abstract

Overview

The location of radiation sources in wireless networks is crucial for characterizing their contribution to electromagnetic exposure levels. This study aims to minimize EM field levels in future network deployments, particularly focusing on signals from WiFi access points.

Methodology

• The research introduces a methodology to determine the threshold distance where the field strength levels from the WiFi access point (AP) are negligible.
• Theoretical concepts applicable to various technologies were tested through simulations and experimental measurements using actual WiFi antennas.

Findings

• Threshold distances where AP radiation is negligible were determined, varying by WiFi standard and device setup.
• Under worst-case scenarios — full network activity and close proximity to a user — threshold distances range significantly, highlighting the conditions that minimize human EM exposure.
• In practical setups, AP transmissions at distances over 5.92 m in open spaces and multipath environments showed reduced influence, suggesting safer user environments.
• Experimental results emphasized the role of signal bandwidth and frequency in determining threshold distances.

Conclusion

This research underlines the importance of setting threshold distances for minimizing EM exposure in WLAN setups. By focusing on both theoretical and practical aspects, it guides future network deployments and measurement suggestions for ensuring safer electromagnetic environments, especially in frequented settings like educational institutions.
