Abstract

Overview

This review provides an in-depth examination of the current technologies and methodologies used in assessing RF electromagnetic field (EMF) exposure, particularly within the context of 5G networks. It addresses the needs and gaps in current measurement tools and methodologies.

Findings

• The review surveys a variety of tools such as spectrum analyzers, broadband field meters, and custom-built devices used for RF-EMF assessment.
• It highlights a growing reliance on mobile apps for data collection concerning 5G NR radio networks.
• A significant emphasis is placed on the development of cost-effective, durable sensors that can perform under varying environmental conditions and are capable of high-resolution data collection across broad geographic and demographic landscapes.
• The challenges with the lack of standardization among custom-developed tools and the need for a comprehensive framework for comparison are discussed.

Conclusion

The study aims to lay the groundwork for further advancements in RF-EMF assessment tools. It calls for a more thorough comparison and validation of these technologies to enhance their effectiveness and reliability in environmental and health risk assessments. The findings stress the importance of developing sensors that can address the dynamically changing needs of RF-EMF measurement, influenced by the rise of 5G technologies.
