Alessandro Polichetti's analysis of the National Center for Radiation Protection and Computational Physics – Istituto Superiore di Sanità – on 5G
The evolution of mobile telephony (whose "fifth generation", or 5G, represents its most recent development) has been characterized by an increasingly dense coverage of the territory, with more and more antennas serving areas ("cells", from which the term "cellular telephony") of increasingly smaller size, to limit the number of people who intend to use the service simultaneously in the same cell. In order to cover these smaller cells, lower and lower powers are required, with a consequent reduction in the environmental levels of the electromagnetic field to which people can be exposed. Furthermore, the reduced size of the cells also leads to a greater proximity between cell phones and fixed antennas, with the consequent reduction of the powers emitted by cell phones and therefore of the users' exposures.
The application of the new fifth generation (5G) mobile phone technology to the Internet of Things , in which not only people but also devices communicate with each other, will give rise to a further increase in "users", and therefore to a further increase in the number of antennas in the area.
This increase is a cause of growing concern in the population, even if in reality, for the reasons mentioned above, the emission powers will always be lower and thus the contribution to the exposure levels which in any case must comply with the precautionary limits set by national legislation : the installation of new antennas in sites where other antennas are already present, in fact, by law cannot lead to an exceeding of the precautionary attention values in force in Italy, as these attention values are expressed in terms of overall values due to all the antennas that generate the electromagnetic fields present in every point of space.
However, it is foreseeable that, with the progressive replacement of the previous technologies with the 5G one, the overall exposures of the population will further decrease compared to what is already happening.
Another cause of concern for the public is that the use of frequencies (approximately 27 GHz) which are very different from those currently used for mobile telephony (800-2.6 GHz) is also envisaged, and this has led to to speak of "unexplored" frequencies from the point of view of health effects. In reality some studies have already been conducted on waves at a few tens of GHz (closer to the frequencies of about 27 GHz). In addition, those used by 5G still belong to the range of radio frequencies, whose mechanisms of interaction with the human body are well understood, and the international exposure limits (and even more so the most conservative Italian limits) allow to fully prevent the known effects of the fields electromagnetic also at these frequencies.
