Abstract

Overview of EMF Exposure in 5G Networks

The rapid expansion of 5G infrastructure, including large antenna arrays, significantly affects electromagnetic field (EMF) exposure levels in mobile networks. This paper reviews the integration of EMF exposure considerations into radio resource management for future mobile communication systems.

Key Findings

• Evaluation of EMF exposure frameworks for 5G networks.
• Analysis of the impacts due to millimeter wave spectrum, network densification, and reconfigurable intelligent surfaces (RIS).
• Examination of EMF-aware radio resource management strategies leveraging RIS.

Challenges and Future Directions

Several challenges persist in the EMF evaluation for 5G systems, notably the implications of RIS technology, which remains under-researched. There is also a notable lack of understanding regarding how EMF-aware resource allocation affects RIS-assisted networks.

Conclusion

Despite advances, significant gaps and research opportunities exist in comprehensively addressing EMF exposure in RIS-enhanced 5G networks.
