Abstract

Overview

The study examines the impact of 4G/5G base stations' electromagnetic radiation on medical short-range devices (MD SRDs) in urban environments. Analysis focuses on three types of systems: capsule endoscopy, body area network, and active implant systems.

Methodology

• Utilization of computer simulations with a multipath radiowave propagation model.
• Development of a 3D model of an urban fragment including buildings ranging from 6 m to 60 m in height.
• Assessment using the integrated interference margin as the electromagnetic compatibility criterion.

Findings

Results indicate that 4G/5G base stations can cause interference to all considered medical devices, especially when emitters are positioned outside buildings while receivers are inside. This interference persists despite adherence to current standards.

Conclusion

Recommendations are presented for enhancing electromagnetic compatibility and ensuring safe operations of medical systems in proximity to 4G/5G base stations, including:

• Implementing more stringent susceptibility requirements.
• Using additional filters to reduce spurious emissions.
• Optimizing placement of base station antennas and medical devices.

The findings underline the risk to medical device operation, suggesting enhancements for standards and system design to prevent potential health impacts from electromagnetic interference in urban settings.
