Abstract

Category: Electromagnetic Field Safety, Machine Learning Tags: 5G, electromagnetic radiation, machine learning, near field, exposure assessment, base stations, radiofrequency safety DOI: 10.3390/app15137302 URL: mdpi.com Overview Electromagnetic radiation measurement and management have become essential in the cost-effective deployment of fifth-generation (5G) infrastructure, particularly as 5G emerges as a service-oriented network. The extensive placement of base stations operating in the millimeter-wave range allows 5G to address high bandwidth demands. Findings - To assess ground-level electromagnetic radiation levels close to 5G base stations, a unique machine-learning-based approach is proposed in this study. - The machine learning model is trained using comprehensive data from numerous 5G base stations and effectively estimates electric field strength across various locations and operational scenarios. - Key input parameters include: - Antenna transmit power - Antenna gain - Terminal service modes - Number of 5G terminals - Distance from terminals to base station - Environmental complexity - Experimental results demonstrate the technique’s feasibility and effectiveness with a mean absolute percentage error (MAPE) of about 5.89%, indicating high reliability. - The developed approach is significantly less expensive than direct on-site measurements. Conclusion The estimates provided by the model can help reduce testing costs and provide practical guidance for optimal base station placement. This can enhance management of electromagnetic radiation from 5G base stations and facilitate the optimization of radio wave coverage. It is vital to note that careful management of electromagnetic fields is necessary due to potential links to health risks—comprehensive assessment and mitigation strategies are essential in 5G deployment.
