Abstract

RF Measurements of EMFs for Human Exposure Assessment Due to Modern Cellular Base Stations (5G) D. Capriglione. In-Situ RF Measurements of EMFs for Human Exposure Assessment Due to Modern Cellular Base Stations. IEEE Instrumentation & Measurement Magazine, vol. 24, no. 8, pp. 31-36, November 2021, doi: 10.1109/MIM.2021.9580794. Abstract TC-37-Measurements and Networking (current Chair Prof. Domenico Capriglione, University of Cassino and Southern Lazio, Italy) was built some years ago as an idea of Prof. Leopoldo Angrisani (University of Napoli Federico II, Italy) and Prof. Claudio Narduzzi (University of Padova, Italy), having in mind that given the complexity of modern networks and related systems, a multidisciplinary approach has to be followed for correctly addressing the technological challenges and issues that are arising and will arise in the future in the field of telecommunication systems and networking. So, the TC-37 is actively trying to promote the international cooperation and integration of researchers belonging to the Instrumentation and Measurement Society with ones coming from other areas of telecommunication and information technologies. Conclusions and Open Issues The measurement of human exposure to RF EMFs is a topic of great interest today because of the growing diffusion and fast evolution of communication technologies. Due to the importance of the topic and the technical difficulties arising from the ever-increasing level of complexity of the communication technologies and experimental scenarios, worldwide researchers are involved in designing and fine-tuning measurement methods, standard procedures, and instruments for achieving reliable results of human exposure. The practical examples in this paper highlight how the research in this field needs continuous updates, and it should involve long-term experimental campaigns for assessing the reliability of measurement techniques and procedures in several experimental conditions and scenarios. These statements are strongly supported by current trends that push to employ DSS (Dynamic Spectrum Sharing) and 5G cellular technologies which will offer new challenges for the measurement of human exposure to EMFs generated by these kinds of sources. In particular, the antenna beamforming and the complexity of 5G technology will require the design of new and effective measurement techniques and protocols able to warrant an adequate tradeoff between accuracy and time needed to completely characterize human exposure in high-density urban scenarios, where several base stations simultaneously operate in the same area. These aspects shall be investigated for both narrowband and broadband approaches. Furthermore, the estimation of the measurement uncertainty will be an important topic to be addressed, taking into account several quantities of influence among which the response of the antennas, probes, and instruments to the signals generated by modern communication systems, as well as the long-term variability of the power emitted by the related Base Stations in given points of analysis should be examined. ieeexplore.ieee.org
