5G mobile networks rated as “high impact” risk for insurance industry
in new Emerging Risk report from Swiss Re

Swiss Re, one of the world’s leading providers of insurance and reinsurance, rated 5G as a “high impact” risk for the insurance industry that may affect property and casualty claims in more than 3 years.

Off the leash – 5G mobile networks

“5G – short for fifth generation – is the latest standard for cellular mobile communications. Providing ultrafast broadband connection with higher capacity and lower latency, 5G is not only heaven for your smartphone. It will enable wireless connectivity in real time for any device of the Internet of things (IoT), whether that be autonomous cars or sensor-steered factory. In doing so, it will allow decentralised seamless interconnectivity between devices. To allow for a functional network coverage and increased capacity overall, more antennas will be needed, including acceptance of higher levels of electromagnetic radiation. In some jurisdictions, the rise of threshold values will require legal adaptation. Existing concerns regarding potential negative health effects from electromagnetic fields (EMF) are only likely to increase. An uptick in liability claims could be a potential long-term consequence.

Other concerns are focused on cyber exposures, which increase with the wider scope of 5G wireless attack surfaces. Traditionally IoT devices have poor security features. Moreover, hackers can also exploit 5G speed and volume, meaning that more data can be stolen much quicker. A large-scale breakthrough of autonomous cars and other IoT applications will mean that security features need to be enhanced at the same pace. Without, interruption and subversion of the 5G platform could trigger catastrophic, cumulative damage. With a change to more automation facilitated by new technology like 5G, we might see a further shift from motor to more general and product liability insurance.  There are also worries about privacy issues (leading to increased litigation risks), security breaches and espionage. The focus is not only on hacking by third parties, but also potential breaches from built-in hard- or software “backdoors.” In addition, the market for 5G infrastructure is currently focussed on a couple of firms, and that raises the spectre of concentration risk. Potential impacts:

•      Cyber exposures are significantly increased with 5G, as attacks become faster and higher in volume. This increases the challenge of defence.
• Growing concerns of the health implications of 5G may lead to political friction and delay of implementation, and to liability claims. The introductions of 3G and 4G faced similar challenges.
• Information security and national sovereignty concerns might delay implementation of 5G further, increasing uncertainty for planning authorities, investors, tech companies and insurers.
• Heated international dispute over 5G contractors and potential for espionage or sabotage could affect international cooperation, and impact financial markets negatively.
• As the biological effects of EMF in general and 5G in particular are still being debated, potential claims for health impairments may come with a long latency.”

5G Deployment

Blackman C, Forge S. 5G Deployment: State of Play in Europe, USA, and Asia. Study for the Committee on Industry, Research and Energy, Policy Department for Economic, Scientific and Quality of Life Policies, European Parliament, Luxembourg, 2019.

Excerpts

“It is becoming clear that 5G [fifth generation cellular technology] will cost much more to deploy than previous mobile technologies (perhaps three times as much) as it is more complex and requires a denser coverage of base stations to provide the expected capacity. The European Commission has estimated that it will cost €500 billion to meet its 2025 connectivity targets, which includes 5G coverage in all urban areas.

As 5G is driven by the telecoms supply industry, and its long tail of component manufacturers, a major campaign is under way to convince governments that the economy and jobs will be strongly stimulated by 5G deployment. However, we are yet to see significant “demand-pull” that could assure sales. These campaign efforts are also aimed at the MNOs [mobile network operators] but they have limited capacity to invest in the new technology and infrastructure as their returns from investment in 3G and 4G are still being recouped.

The notion of a “race” is part of the campaign but it is becoming clear that the technology will take much longer than earlier generations to perfect. China, for instance, sees 5G as at least a ten-year programme to become fully working and completely rolled out nationally. This is because the technologies involved with 5G are much more complex. One aspect, for example, that is not well understood today is the unpredictable propagation patterns that could result in unacceptable levels of human exposure to electromagnetic radiation.”

“Although lower frequencies, many in the UHF [ultra high frequency] range, are being proposed for the first phase of 5G networks, much higher radio frequencies are also projected in bands traditionally used for radars and microwave links. Whether this will transpire is still open to question. These frequencies are being commercially tested by some (e.g. by AT&T in the USA at 28 GHz [gigahertz]). The new bands are well above the UHF ranges, being either in centimetric (3-30 GHz) or in millimetric bands (30-300 GHz) and popularly branded “mmWave”, but present technical challenges that are expensive to solve.”

“Although many 5G networks currently being piloted will use the much lower bands, those upper frequencies being proposed for the future may offer propagation ranges only in the order of hundreds or even tens of metres. Higher frequency signals are also subject to more interference from weather – rain, snow, fog – and obstacles – wet foliage or buildings and their walls. This means that, at higher frequencies, indoor use may be problematic if based on through-wall or window penetration. Consequently, re-use of the existing UHF bands and also those just above in the 3-10 GHz range (“mid-range”) are emphasised today, to give 5G signals greater range with fewer technical challenges.”

“With higher frequencies and shortened ranges, base stations will be more closely packed into a given area to give complete coverage that avoids “not-spots”. Ranges of 20-150 metres may be typical, giving smaller coverage areas per “small cell”. A cell radius of 20 metres would imply about 800 base stations per square kilometre (or small area wireless access points (SAWAPs), the term used in the European Electronic Communications Code (EECC)). That contrasts with 3G and 4G which use large or “macro” cells. Traditionally they offer ranges of 2-15 km or more and so can cover a larger area but with fewer simultaneous users as they have fewer individual channels.”

5G Electromagnetic Radiation and Safety

“Significant concern is emerging over the possible impact on health and safety arising from potentially much higher exposure to radiofrequency electromagnetic radiation arising from 5G. Increased exposure may result not only from the use of much higher frequencies in 5G but also from the potential for the aggregation of different signals, their dynamic nature, and the complex interference effects that may result, especially in dense urban areas.

The 5G radio emission fields are quite different to those of previous generations because of their complex beamformed transmissions in both directions – from base station to handset and for the return. Although fields are highly focused by beams, they vary rapidly with time and movement and so are unpredictable, as the signal levels and patterns interact as a closed loop system. This has yet to be mapped reliably for real situations, outside the laboratory.

While the International Commission on Non-Ionizing Radiation Protection (ICNIRP) issues guidelines for limiting exposure to electric, magnetic and electromagnetic fields (EMF), and EU member states are subject to Council Recommendation 1999/519/EC which follows ICNIRP guidelines, the problem is that currently it is not possible to accurately simulate or measure 5G emissions in the real world.”

USA

“The USA is moving towards some form of rollout of mobile broadband as 5G but not necessarily in a holistic, well-orchestrated operation. It is more a set of ad hoc commercial manoeuvres. Some of these are simply rebranding existing LTE, rather than delivering novel networks. Re-use of the LTE spectrum in the UHF ranges (300 MHz to 3 GHz) is significant. The latter decision is probably warranted by its geography of large rural spaces and high density urban centres situated more on the coasts. Thus, the insistence for 5G on high centimetric bands (25–30 GHz and higher) is probably less justified than for the dense conurbations of Asia and the EU.

A significant challenge concerns the administrative local barriers to small cell rollout. The need for many small cells implies long delays and high costs. Local regulations continue to prevail despite the FCC’s mandate on a light-touch regime and minimal permit costs. This has led to a wide divide between local and central government on the principles of having to obtain permission for rollout and the charges for that. Local administrations, especially in the larger municipalities, are at loggerheads with the FCC (Zima, 2018). Several court challenges are being made to the FCC mandate of August 2018 that overrides local objections to a “one-touch” regime.”

How Harmful is 5G?

Harald Schumann and Elisa Simantke. How harmful is 5G really? Der Tagesspiegel, Jan 15, 2019. (In German. For English translation email me at jmm@berkeley.edu.)

“5G should transfer huge amounts of data quickly. But it could also harm your health. Europe’s governments ignore the danger.”

Investigate Europe reports on the current state of the science and exposes the harmful roles that the International Commission on Non-Ionizing Radiation Protection (ICNIRP), the World Health Organization’s International EMF Project,  and the EU Commission’s Scientific Committee on New Health Risks (SCENIHR) have played in paving the way for the deployment of 5G without regard to health consequences.

Investigate Europe is a pan-European journalist team that researches topics of European relevance and publishes the results across Europe. The project is supported by several foundations, the Open Society Initiative for Europe, and readers’ donations. Among the media partners for the report on 5G include “Newsweek Polska”, “Diario de Noticias”, “Il Fatto Quotidiano”, “De Groene Amsterdamer”, “Efimerida ton Syntakton”, “Aftenbladet” and the “Falter”. In addition to the authors, Crina Boros, Wojciech Ciesla, Ingeborg Eliassen, Juliet Ferguson, Nikolas Leontopoulos, Maria Maggiore, Leila Minano, Paulo Pena and Jef Poortmans contributed to this.

5G Wireless Communication and Health Effects-A Pragmatic Review Based on Available Studies Regarding 6 to 100 GHz

Simkó M, Mattsson MO. 5G wireless communication and health effects-A pragmatic review based on available studies regarding 6 to 100 GHz. Int J Environ Res Public Health. 2019 Sep 13;16(18). pii: E3406. doi: 10.3390/ijerph16183406.

Abstract

The introduction of the fifth generation (5G) of wireless communication will increase the number of high-frequency-powered base stations and other devices. The question is if such higher frequencies (in this review, 6-100 GHz, millimeter waves, MMW) can have a health impact. This review analyzed 94 relevant publications performing in vivo or in vitro investigations. Each study was characterized for: study type (in vivo, in vitro), biological material (species, cell type, etc.), biological endpoint, exposure (frequency, exposure duration, power density), results, and certain quality criteria. Eighty percent of the in vivo studies showed responses to exposure, while 58% of the in vitro studies demonstrated effects. The responses affected all biological endpoints studied. There was no consistent relationship between power density, exposure duration, or frequency, and exposure effects. The available studies do not provide adequate and sufficient information for a meaningful safety assessment, or for the question about non-thermal effects. There is a need for research regarding local heat developments on small surfaces, e.g., skin or the eye, and on any environmental impact. Our quality analysis shows that for future studies to be useful for safety assessment, design and implementation need to be significantly improved.

Conclusions

Since the ranges up to 30 GHz and over 90 GHz are sparingly represented, this review mainly covers studies done in the frequency range from 30.1 to 65 GHz.

In summary, the majority of studies with MMW exposures show biological responses. From this observation, however, no in-depth conclusions can be drawn regarding the biological and health effects of MMW exposures in the 6–100 GHz frequency range. The studies are very different and the total number of studies is surprisingly low. The reactions occur both in vivo and in vitro and affect all biological endpoints studied.

There does not seem to be a consistent relationship between intensity (power density), exposure time, or frequency, and the effects of exposure. On the contrary, and strikingly, higher power densities do not cause more frequent responses, since the percentage of responses in most frequency groups is already at 70%. Some authors refer to their study results as having “non-thermal” causes, but few have applied appropriate temperature controls. The question therefore remains whether warming is the main cause of any observed MMW effects?

In order to evaluate and summarize the 6–100 GHz data in this review, we draw the following conclusions:

• Regarding the health effects of MMW in the 6–100 GHz frequency range at power densities not exceeding the exposure guidelines the studies provide no clear evidence, due to contradictory information from the in vivo and in vitro investigations.
• Regarding the possibility of “non-thermal” effects, the available studies provide no clear explanation of any mode of action of observed effects.
• Regarding the quality of the presented studies, too few studies fulfill the minimal quality criteria to allow any further conclusions.

EMF safety guidelines are fraudulent: 

The consequences for microwave frequency exposures and 5G

Pall M. Eight repeatedly documented findings each show that EMF safety guidelines do not predict biological effects and are, therefore fraudulent: The consequences for both microwave frequency exposures and also 5G. Second Edition, May 23, 2019.

Abstract

ICNIRP, US FCC, EU and other EMF safety guidelines are all based on the assumption that
average EMF intensities and average SAR can be used to predict biological effects and therefore safety. Eight different types of quantitative or qualitative data are analyzed here to determine whether these safety guidelines predict biological effects. In each case the safety guidelines fail and in most of these, fail massively. Effects occur at approximately 100,000 times below allowable levels and the basic structure of the safety guidelines is shown to be deeply flawed. The safety guidelines ignore demonstrated biological heterogeneity and established biological mechanisms. Even the physics underlying the safety guidelines is shown to be flawed. Pulsed EMFs are in most cases much more biologically active than are non-pulsed EMFs of the same average intensity, but pulsations are ignored in the safety guidelines despite the fact that almost all of our current exposures are highly pulsed. There are exposure windows such that maximum effects are produced in certain intensity windows and also in certain frequency windows but the consequent very complex dose-response curves are ignored by the safety guidelines. Several additional flaws in the safety guidelines are shown through studies of both individual and paired nanosecond pulses. The properties of 5G predict that guidelines will be even more flawed in predicting 5G effects than the already stunning flaws that the safety guidelines have in predicting our other EMF exposures. The consequences of these findings is that “safety guidelines” should always be expressed in quotation marks; they do not predict biological effects and therefore do not predict safety. Because of that we have a multi-trillion dollar set of companies, the telecommunication industry, where all assurances of safety are fraudulent because they are based on these “safety guidelines.”

5G Wireless Telecommunications Expansion: Public Health & Environmental Implications

Russell CL. 5G wireless telecommunications expansion: Public health and environmental implications. Environmental Research.  2018 Aug;165:484-495. doi: 10.1016/j.envres.2018.01.016.

Abstract

The popularity, widespread use and increasing dependency on wireless technologies has spawned a telecommunications industrial revolution with increasing public exposure to broader and higher frequencies of the electromagnetic spectrum to transmit data through a variety of devices and infrastructure. On the horizon, a new generation of even shorter high frequency 5G wavelengths is being proposed to power the Internet of Things (IoT). The IoT promises us convenient and easy lifestyles with a massive 5G interconnected telecommunications network, however, the expansion of broadband with shorter wavelength radiofrequency radiation highlights the concern that health and safety issues remain unknown. Controversy continues with regards to harm from current 2G, 3G and 4G wireless technologies. 5G technologies are far less studied for human or environmental effects.

It is argued that the addition of this added high frequency 5G radiation to an already complex mix of lower frequencies, will contribute to a negative public health outcome both from both physical and mental health perspectives.

Radiofrequency radiation (RF) is increasingly being recognized as a new form of environmental pollution. Like other common toxic exposures, the effects of radiofrequency electromagnetic radiation (RF EMR) will be problematic if not impossible to sort out epidemiologically as there no longer remains an unexposed control group. This is especially important considering these effects are likely magnified by synergistic toxic exposures and other common health risk behaviors. Effects can also be non-linear. Because this is the first generation to have cradle-to-grave lifespan exposure to this level of man-made microwave (RF EMR) radiofrequencies, it will be years or decades before the true health consequences are known. Precaution in the roll out of this new technology is strongly indicated.

This article will review relevant electromagnetic frequencies, exposure standards and current scientific literature on the health implications of 2G, 3G, 4G exposure, including some of the available literature on 5G frequencies. The question of what constitutes a public health issue will be raised, as well as the need for a precautionary approach in advancing new wireless technologies.

Conclusion

Although 5G technology may have many unimagined uses and benefits, it is also increasingly clear that significant negative consequences to human health and ecosystems could occur if it is widely adopted. Current radiofrequency radiation wavelengths we are exposed to appear to act as a toxin to biological systems. A moratorium on the deployment of 5G is warranted, along with development of independent health and environmental advisory boards that include independent scientists who research biological effects and exposure levels of radiofrequency radiation. Sound regulatory policy regarding current and future telecommunications initiative will require more careful assessment of risks to human health, environmental health, public safety, privacy, security and social consequences. Public health regulations need to be updated to match appropriate independent science with the adoption of biologically based exposure standards prior to further deployment of 4G or 5G technology.

Considering the current science, lack of relevant exposure standards based on known biological effects and data gaps in research, we need to reduce our exposure to RF EMR where ever technically feasible. Laws or policies which restrict the full integrity of science and the scientific community with regards to health and environmental effects of wireless technologies or other toxic exposures should be changed to enable unbiased, objective and precautionary science to drive necessary public policies and regulation. Climate change, fracking, toxic emissions and microwave radiation from wireless devices all have something in common with smoking. There is much denial and confusion about health and environmental risks, along with industry insistence for absolute proof before regulatory action occurs (Frentzel-Beyme, 1994; Michaels 2008). There are many lessons we have not learned with the introduction of novel substances, which later became precarious environmental pollutants by not heeding warning signs from scientists (Gee, 2009). The threats of these common pollutants continue to weigh heavily on the health and well being of our nation. We now accept them as the price of progress. If we do not take precautions but wait for unquestioned proof of harm will it be too late at that point for some or all of us?

Towards 5G Communication Systems: Are there Health Implications?

Di Ciaula A. Towards 5G communication systems: Are there health implications? Int J Hyg Environ Health. 2018 Apr;221(3):367-375. doi: 10.1016/j.ijheh.2018.01.011.

Highlights

• RF-EMF exposure is rising and health effects of are still under investigation.• Both oncologic and non-cancerous chronic effects have been suggested.• 5G networks could have health effects and will use MMW, still scarcely explored.• Adequate knowledge of RF-EMF biological effects is also needed in clinical practice.• Underrating the problem could lead to a further rise in noncommunicable diseases.

Abstract

The spread of radiofrequency electromagnetic fields (RF-EMF) is rising and health effects are still under investigation. RF-EMF promote oxidative stress, a condition involved in cancer onset, in several acute and chronic diseases and in vascular homeostasis. Although some evidences are still controversial, the WHO IARC classified RF-EMF as “possible carcinogenic to humans”, and more recent studies suggested reproductive, metabolic and neurologic effects of RF-EMF, which are also able to alter bacterial antibiotic resistance.

In this evolving scenario, although the biological effects of 5G communication systems are very scarcely investigated, an international action plan for the development of 5G networks has started, with a forthcoming increment in devices and density of small cells, and with the future use of millimeter waves (MMW).

Preliminary observations showed that MMW increase skin temperature, alter gene expression, promote cellular proliferation and synthesis of proteins linked with oxidative stress, inflammatory and metabolic processes, could generate ocular damages, affect neuro-muscular dynamics.

Further studies are needed to better and independently explore the health effects of RF-EMF in general and of MMW in particular. However, available findings seem sufficient to demonstrate the existence of biomedical effects, to invoke the precautionary principle, to define exposed subjects as potentially vulnerable and to revise existing limits. An adequate knowledge of pathophysiological mechanisms linking RF-EMF exposure to health risk should also be useful in the current clinical practice, in particular in consideration of evidences pointing to extrinsic factors as heavy contributors to cancer risk and to the progressive epidemiological growth of noncommunicable diseases.

Effects of Millimeter Waves Radiation on Cell Membrane – A Brief Review

Ramundo-Orlando A.  Effects of millimeter waves radiation on cell membrane – A brief review.  J Infrared Milli Terahz Waves. 2010; 30 (12): 1400-1411.

Abstract

The millimeter waves (MMW) region of the electromagnetic spectrum, extending from 30 to 300 GHz in terms of frequency (corresponding to wavelengths from 10 mm to 1 mm), is officially used in non-invasive complementary medicine in many Eastern European countries against a variety of diseases such gastro duodenal ulcers, cardiovascular disorders, traumatism and tumor. On the other hand, besides technological applications in traffic and military systems, in the near future MMW will also find applications in high resolution and high-speed wireless communication technology. This has led to restoring interest in research on MMW induced biological effects. In this review emphasis has been given to the MMW-induced effects on cell membranes that are considered the major target for the interaction between MMW and biological systems.

https://link.springer.com/article/10.1007%2Fs10762-010-9731-z

Excerpts

“Several studies on the effects induced by millimeter radiation on biological systems have been reported in the literature. Diverse effects have been observed on cell free systems, cultured cells, isolated organs of animals and humans. The subject has been extensively reviewed by Motzkin [17] and more recently by Pakhomov [3]. At the cellular level these effects are mainly on the membrane process and ion channels, molecular complexes, excitable and other structures. Many of these effects are quite unexpected from a radiation penetrating less than 1 mm into biological tissues [3, 18, 19]. However none of the findings described in the above reviews has been replicated in an independent laboratory, thus they cannot be considered as established biological effects.”

“…a large number of cellular studies have indicated that MMW may alter structural and functional properties of membranes (Table 2).”

Conclusion

“In this review emphasis has been given to the low-level MMW effects on cell membranes. Above all, it should be mentioned that the reported effects are of a non-thermal character, that is, the action of radiation does not produce essential heating of the biological system or destroy its structure. In this context it appears that no permanent structural change of lipid bilayer could arise under low level (less than 10 mW/cm2) millimeter waves irradiation.

On the other hand, MMW radiation may affect intracellular calcium activities, and, as a consequence, several cellular and molecular processes controlled by Ca2+ dynamics themselves. The effects of MMW radiation on ion transport may be the consequence of a direct effect on membrane proteins as well as on phospholipid domain organization. Water molecules seem to play an important role in these biological effects of MMW radiation. Unfortunately, detailed cellular and molecular mechanisms mediating physiological responses to MMW exposure remain largely unknown.

Usually the search at a molecular level is simpler if we can reduce the complexity of our biological samples. This is the case for cell membranes by using model systems. They can be formed by a simple lipid bilayer without interfering components and they give independence from biological activity that can create complication in searching for electromagnetic fields bioeffects. The emphasis is on the search for molecular mechanisms of the membrane effect induced by MMW with different frequencies and power density. Furthermore, replication studies are needed including good temperature control and appropriate internal control samples. It is also advantageous if the future studies are multidisciplinary, invoking an integration of high quality exposure and effects methodologies.

Clearly a significant amount of accurate experimental work is still required in order to fully understand the interactions between MMW radiation and cell membrane.”

A Survey on Electromagnetic Risk Assessment and Evaluation Mechanism for Future Wireless Communication Systems

Jamshed MA, Heliot F, Brown T. A Survey on Electromagnetic Risk Assessment and Evaluation Mechanism for Future Wireless Communication Systems. IEEE Journal of Electromagnetics, RF and Microwaves in Medicine and Biology. May 20, 2019. DOI: 10.1109/JERM.2019.2917766

Abstract

The accurate measurement of electromagnetic exposure and its application is expected to become more and more important in future wireless communication systems, given the explosion in both the number of wireless devices and equipments radiating electromagnetic-fields (EMF) and the growing concerns in the general public linked to it. Indeed, the next generation of wireless systems aims at providing a higher data rate,better quality of service (QoS), and lower latency to users by increasing the number of access points, i.e. densification, which in turn will increase EMF exposure. Similarly, the multiplication of future connected devices,e.g. internet of things (IoT) devices, will also contribute to an increase in EMF exposure. This paper provides a detailed survey relating to the potential health hazards linked with EMF exposure and the different metrics that are currently used for evaluating,limiting and mitigating the effects of this type of exposure on the general public. This paper also reviews the possible impacts of new wireless technologies on EMF exposure and proposes some novel research directions for updating the EMF exposure evaluation framework and addressing these impacts in future wireless communication systems. For instance, the impact of mmWave or massive-MIMO/beamforming on EMF exposure has yet to be fully understood and included in the exposure evaluation framework.

Conclusions

A thorough survey on exposure risk assessment, evaluation, limitation and mitigation for current and future wireless devices and equipments has been provided in this paper. From the human health point of view, it seems that the possibility of brain tumor is still the main cause of concerns related to the extensive use of wireless devices, even though the effects of EMF exposure is now being investigated in new parts of the body (e.g. eyes). Meanwhile, with the advent of 5G, more efforts are now been made to understand the thermal and non-thermal effects of mmWave exposure on the human body. When it comes to the evaluation of EMF exposure, we have presented the most common evaluation frameworks and metrics that are utilized in wireless communications to measure the exposure. We have also explained how new more generic metrics have been defined by combining existing metrics to better reflect the exposure of large geographical areas and have argued that a generic metric for measuring the individual exposure would also be of interest. We have also reviewed the existing exposure guidelines and have explained how they can be updated for better reflecting the true nature of EMF exposure, i.e. by better taking into account the duration of exposure. Finally, we have provided some views on how key 5G enabling technologies such as densification, massive MIMO and mmWave will impact the EMF exposure in the near future; for instance, the dense deployment of small cells and IoT devices is very likely to increase the overall ambient exposure. We also believe that there could be some technical opportunities in 5G to increase the exposure awareness of wireless system users and to let them decide if they want to reduce it at the cost of, for instance, a lower QoS.

Assessment of Maximally Allowable Power-Density Averaging Area for EMF Exposure above 6 GHz

Neufeld E, Carrasco E, Murbach M, Balzano Q, Christ A, Kuster N. Theoretical and numerical assessment of maximally allowable power-density averaging area for conservative electromagnetic exposure assessment above 6 GHz.  Bioelectromagnetics.  2018 Dec;39(8):617-630. doi: 10.1002/bem.22147.

Abstract

The objective of this paper is to determine a maximum averaging area for power density (PD) that limits the maximum temperature increase to a given threshold for frequencies above 6 GHz. This maximum area should be conservative for any transmitter at any distance >2 mm from the primary transmitting antennas or secondary field-generating sources. To derive a generically valid maximum averaging area, an analytical approximation for the peak temperature increase caused by localized exposure was derived. The results for a threshold value of 1 K temperature rise were validated against simulations of a series of sources composed of electrical and magnetic elements (dipoles, slots, patches, and arrays) that represented the spectrum of relevant transmitters. The validation was successful for frequencies in which the power deposition occurred superficially (i.e., >10 GHz). In conclusion, the averaging area for a PD limit of 10 W/m2 that conservatively limits the temperature increase in the skin to less than 1 K at any distance >2 mm from the transmitters is frequency dependent, increases with distance, and ranges from 3 cm2 at <10 GHz to 1.9 cm2 at 100 GHz. In the far-field, the area depends additionally on distance and the antenna array aperture. The correlation was found to be worse at lower frequencies (<10 GHz) and very close to the source, the systematic evaluation of which is part of another study to investigate the effect of different coupling mechanisms in the reactive near-field on the ratio of temperature increase to incident power density. The presented model can be directly applied to any other PD and temperature thresholds.

The Human Skin as a Sub-THz Receiver – Does 5G Pose a Danger to It or Not?

Betzalel N, Ben Ishai P, Feldman Y. The human skin as a sub-THz receiver – Does 5G pose a danger to it or not? Environ Res. 2018 May;163:208-216.

Highlights

• The sweat duct is regarded as a helical antenna in the sub-THz band, reflectance depends on perspiration.
• We outline the background for non-thermal effects based on the structure of sweat ducts.
• We have introduced a realistic skin EM model and found the expected SAR for the 5G standard.

Abstract

In the interaction of microwave radiation and human beings, the skin is traditionally considered as just an absorbing sponge stratum filled with water. In previous works, we showed that this view is flawed when we demonstrated that the coiled portion of the sweat duct in upper skin layer is regarded as a helical antenna in the sub-THz band.

Experimentally we showed that the reflectance of the human skin in the sub-THz region depends on the intensity of perspiration, i.e. sweat duct’s conductivity, and correlates with levels of human stress (physical, mental and emotional). Later on, we detected circular dichroism in the reflectance from the skin, a signature of the axial mode of a helical antenna. The full ramifications of what these findings represent in the human condition are still unclear. We also revealed correlation of electrocardiography (ECG) parameters to the sub-THz reflection coefficient of human skin. In a recent work, we developed a unique simulation tool of human skin, taking into account the skin multi-layer structure together with the helical segment of the sweat duct embedded in it. The presence of the sweat duct led to a high specific absorption rate (SAR) of the skin in extremely high frequency band.

In this paper, we summarize the physical evidence for this phenomenon and consider its implication for the future exploitation of the electromagnetic spectrum by wireless communication. Starting from July 2016 the US Federal Communications Commission (FCC) has adopted new rules for wireless broadband operations above 24 GHz (5 G). This trend of exploitation is predicted to expand to higher frequencies in the sub-THz region. One must consider the implications of human immersion in the electromagnetic noise, caused by devices working at the very same frequencies as those, to which the sweat duct (as a helical antenna) is most attuned.

We are raising a warning flag against the unrestricted use of sub-THz technologies for communication, before the possible consequences for public health are explored.

Excerpt

The need for high data transmission rates, coupled with advances in semiconductor technology, is pushing the communications industry towards the sub-THz frequency spectrum. While the promises of a glorious future, resplendent with semi-infinite data streaming, may be attractive, there is a price to pay for such luxury. We shall find our cities, workspace and homes awash with 5 G base stations and we shall live though an unprecedented EM smog. The benefits to our society of becoming so wired cannot ignore possible health concerns, as yet unexplored. There is enough evidence to suggest that the combination of the helical sweat duct and wavelengths approaching the dimensions of skin layers could lead to non-thermal biological effects. Such fears should be investigated and these concerns should also effect the definition of standards for the application of 5G communications.

On Measuring Electromagnetic Fields in 5G Technology

Pawlak R, Krawiec P, Żurek J. On measuring electromagnetic fields in 5G technology. IEEE Access. 7: 29826-29835. March 5, 2019. DOI: 10.1109/ACCESS.2019.2902481

Abstract

At the awakening of the new 5G network as the network of services, issues related to electromagnetic fields (EMFs) will become one of the key aspects for the cost-effective establishment of the 5G infrastructure. The new 5G services will meet the rigorous demand for bandwidth through the implementation of a large number of densely located base stations operating in the millimeter-wave range. Introduction of new emission sources, working in parallel with already existing 2G/3G/4G mobile technologies, raises concerns about exceeding the admissible EMF exposure limits. This paper analyzes issues and challenges related to EMF measurements in 5G technology, which are crucial for the assessment of EMF compliance with regulatory limits. We point out that the existing methodologies, dedicated to EMF measurements in 2G, 3G, and 4G networks, are not suitable for 5G. The reason is the use of new techniques, such as massive MIMO and precise beamforming together with higher frequency bands so that the existing measurement methods can lead to significantly overestimated results when they will be applied to 5G networks. Such results, in conjunction with the restrictive legislation on the EMF limits that apply in some countries, may have the negative impact on 5G network deployment, making it difficult to achieve the intended 5G network capabilities. We also propose an alternative method of EMF exposure assessment that is based on calculations and simulations and allows obtaining an accurate estimation of the EMF distribution in the 5G environment.

Radio Frequency Electromagnetic Field Exposure Assessment for Future 5G Networks

Persia S, Carciofi C, Barbiroli M, Volta C, Bontempelli D, Anania G. Radio frequency electromagnetic field exposure assessment for future 5G networks. IEEE 29th Annual International Symposium on Personal, Indoor and Mobile Radio Communications (PIMRC), 2018. IEEE, 2018. doi:10.1109/PIMRC.2018.8580919

Abstract

The fifth generation of mobile network (5G) will relay not only on the expansion of existing fourth (4G) Long Term Evolution (LTE) network, but thanks to the introduction of new radio access in the millimetre wave bands will allow to meet new requirements in terms of connectivity and capacity. Specifically, 5G network will be characterized by the use of new spectrum at higher frequencies with a very large number of antenna elements deployment. As a consequence, the RF EMF (Radio Frequency Electromagnetic Field) compliance assessments with the regulatory requirements for human exposure for the installation permission needs to be revised accordingly. In this work, a Country case (Italy), where a more restrictive regulatory framework than the ICNIRP Guidelines is applied, has been analysed to investigate the impact of the restrictive approach on the future 5G mobile networks roll-out.

Conclusions

The EMF evaluations of existing cellular networks has been analysed in this work in order to highlight how restrictive regulatory framework than International Guidelines can affect 5G and future network deployment. Italy case study is considered as an example, due to its restrictive regulation to verify if it can permit an efficient 5G roll-out. This consideration has been confirmed by evaluations of the trend of saturated sites from 2010 to 2017 in Italy. Simulations demonstrate that in Italy the strong development expected for the evolution of 4G networks and, in the perspective of 5G systems, can be threatened with the stringent constraints imposed by the current regulatory framework for exposure to electromagnetic fields.

Derivation of Safety Limits for 5G RF Exposure Based on Analytical Models & Thermal Dose

Neufeld E, Kuster N. Systematic Derivation of Safety Limits for Time-Varying 5G Radiofrequency Exposure Based on Analytical Models and Thermal Dose. Health Phys. 2018 Sep 21. 705-711. doi: 10.1097/HP.0000000000000930.

Abstract

Extreme broadband wireless devices operating above 10 GHz may transmit data in bursts of a few milliseconds to seconds. Even though the time- and area-averaged power density values remain within the acceptable safety limits for continuous exposure, these bursts may lead to short temperature spikes in the skin of exposed people. In this paper, a novel analytical approach to pulsed heating is developed and applied to assess the peak-to-average temperature ratio as a function of the pulse fraction α (relative to the averaging time T; it corresponds to the inverse of the peak-to-average ratio). This has been analyzed for two different perfusion-related thermal time constants (τ1 = 100 s and 500 s) corresponding to plane-wave and localized exposures. To allow for peak temperatures that considerably exceed the 1 K increase, the CEM43 tissue damage model, with an experimental-data-based damage threshold for human skin of 600 min, is used to allow large temperature oscillations that remain below the level at which tissue damage occurs. To stay consistent with the current safety guidelines, safety factors of 10 for occupational exposure and 50 for the general public were applied. The model assumptions and limitations (e.g., employed thermal and tissue damage models, homogeneous skin, consideration of localized exposure by a modified time constant) are discussed in detail.

The results demonstrate that the maximum averaging time, based on the assumption of a thermal time constant of 100 s, is 240 s if the maximum local temperature increase for continuous-wave exposure is limited to 1 K and α ≥ 0.1. For a very low peak-to-average ratio of 100 (α ≥ 0.01), it decreases to only 30 s. The results also show that the peak-to-average ratio of 1,000 tolerated by the International Council on Non-Ionizing Radiation Protection guidelines may lead to permanent tissue damage after even short exposures, highlighting the importance of revisiting existing exposure guidelines.

Human Exposure to RF Fields in 5G Downlink

Nasim I, Kim S. Human Exposure to RF Fields in 5G Downlink. Submitted on 10 Nov 2017 to IEEE International Communications Conference. arXiv:1711.03683v1.

Abstract

While cellular communications in millimeter wave (mmW) bands have been attracting significant research interest, their potential harmful impacts on human health are not as significantly studied. Prior research on human exposure to radio frequency (RF) fields in a cellular communications system has been focused on uplink only due to the closer physical contact of a transmitter to a human body. However, this paper claims the necessity of thorough investigation on human exposure to downlink RF fields, as cellular systems deployed in mmW bands will entail (i) deployment of more transmitters due to smaller cell size and (ii) higher concentration of RF energy using a highly directional antenna. In this paper, we present human RF exposure levels in downlink of a Fifth Generation Wireless Systems (5G). Our results show that 5G downlink RF fields generate significantly higher power density (PD) and specific absorption rate (SAR) than a current cellular system. This paper also shows that SAR should also be taken into account for determining human RF exposure in the mmW downlink.

Colombi D, Thors B, Törnevik C. Implications of EMF exposure limits on output power levels for 5G devices above 6 GHz. IEEE Antennas and Wireless Propagation Letters. 14:1247-1249. 04 February 2015. DOI: 10.1109/LAWP.2015.2400331.

Abstract

Spectrum is a scarce resource, and the interest for utilizing frequency bands above 6 GHz for future radio communication systems is increasing. The possible use of higher frequency bands implies new challenges in terms of electromagnetic field (EMF) exposure assessments since the fundamental exposure metric (basic restriction) is changing from specific absorption rate (SAR) to power density. In this study, the implication of this change is investigated in terms of the maximum possible radiated power (P max ) from a device used in close proximity to the human body. The results show that the existing exposure limits will lead to a non-physical discontinuity of several dB in P max as the transition is made from SAR to power density based basic restrictions. As a consequence, to be compliant with applicable exposure limits at frequencies above 6 GHz, P max might have to be several dB below the power levels used for current cellular technologies. Since the available power in uplink has a direct impact on the system capacity and coverage, such an inconsistency, if not resolved, might have a large effect on the development of the next generation cellular networks (5G).

Conclusion

Above 6 GHz for FCC and 10 GHz for ICNIRP, EMF exposure limits are defined in terms of free-space power density rather than SAR. It was shown that at the transition frequency where the exposure metric changes, the maximum radiated power to meet compliance with ICNIRP and FCC EMF limits, for a device used in close proximity of the body, presents a strong discontinuity (in the order of 6 dB for the investigated case). This discrepancy has no scientific basis and is due to inconsistencies in the exposure limits. As a consequence, the estimated maximum output power in uplink for devices operating at frequencies above 6-10 GHz is about 18 dBm and 15 dBm for ICNIRP and FCC, respectively. These figures were obtained by numerical simulations of a canonical dipole at frequencies up to 70 GHz. It was shown that for more directive antennas, the maximum available power can be substantially lower. For the IEEE limits, the incongruity at the transition frequency is less evident. This is because the IEEE PD limits make use of a larger averaging area than the ICNIRP and FCC limits. The IEEE limits, however, have not yet been adopted in any national regulations.

With a growing interest for utilizing frequency bands above 6 GHz for mobile communications, it is important that the inconsistencies at the transition frequency from SAR to PD based basic restrictions are timely solved. If not, the observed discrepancy might have a large impact on the development of future mobile communication networks. We therefore encourage the relevant standardization organizations and regulatory authorities responsible for defining EMF exposure limits to address this issue.

Scientists and Physicians Oppose
“Small Cell” Antenna Bill (Calif. SB 649)

I have been hearing from scientists around the world who are deeply concerned about the deployment of fifth generation (5G) wireless technology without adequate research on the health effects of exposure to this type of radio frequency radiation.

Following is a sample of letters sent to California Governor Brown asking him to veto SB 659, a “small cell” antenna bill written by the cellular industry that paves the way for deployment of 5G wireless technology across the state.

Professor Beatrice Golomb, MD, PhD, a professor of medicine in the School of Medicine at the University of California, San Diego. Dr. Golomb’s letter begins with the following warning:
“I urge in the strongest terms that you vigorously oppose California SB 649.If this bill passes, many people will suffer greatly, and needlessly, as a direct result. This sounds like hyperbole. It is not.My research group at UC San Diego alone has received hundreds of communications from people who have developed serious health problems from electromagnetic radiation, following introduction of new technologies. Others with whom I am in communication, have independently received hundreds of similar reports. Most likely these are a tip of an iceberg of tens or perhaps hundreds of thousands of affected person. As each new technology leading to further exposure to electromagnetic radiation is introduced – and particularly introduced in a fashion that prevents vulnerable individuals from avoiding it – a new group become sensitized to health effects. This is particularly true for pulsed signals in the radiowave and microwave portion of the spectrum, the type for which the proposed bill SB 640 will bypass local control.”In the letter, Dr. Golomb summarizes the research on the effects of exposure to radio frequency radiation and advocates for “safer, wired and well shielded technology – not more wireless.”

Appended to the letter are 360 references to the scientific literature.

The letter can be downloaded at: http://bit.ly/SB649Golomb822.

Professor Martin Pall, PhD, Professor Emeritus of Biochemistry and Basic Medical Sciences at Washington State University, explains in his letter to the Governor his peer-reviewed research which has documented …
“exquisite sensitivity to electromagnetic fields (EMFs) in the voltage sensors in each cell, such that the force impacting our cells at the voltage sensor has massive impact on the biology in the cells of our bodies.””This new understanding [1-7] means we can debunk the claims of the wireless industry that there cannot be a mechanism for effects produced by these weak EMFs. The 20 years plus of industry propaganda claims are false. Rather the thousands of studies showing diverse health impacts of these EMFs can be explained. We now have a mechanism, one that is supported by both the biology and the physics, both of which are pointing in exactly the same direction.””5G will be much more active in activating the VGCCs and producinghealth impacts because of its rapid absorption by materials in the body, because of its very rapid pulsations and because of the huge number antennae they are planning to put up, at least 200 times the number of antennae from all current cell phone towers. What this means is that the impacts on the outer one to two inches of our bodies will be massive.”
His letter discusses the potential health impacts on humans and on agriculture with exposure to 5G radiation.

The letter can be downloaded at: http://bit.ly/SB649Pall

Dr. Michael Lipsett, MD, JD, a retired public health physician with extensive experience in environmental health, mentions in his letter the recent demand for a 5G moratorium by more than 180 scientists and physicians and the study of cell phone radiation conducted by the National Toxicology Program.

He points out that while individuals can take precautions to reduce their exposure to radiofrequency radiation emitted by wireless devices, this is not feasible with exposure from cell antennas. He notes that …
“laboratory and human health investigations designed and conducted by independent researchers have reported associations linking exposure to radiation from cell phones or similar devices with multiple adverse effects (e.g., headaches, impacts on brain function, memory, learning and sleep; decreased sperm counts and quality) as well as with DNA damage and tumors of the brain and nervous system.””Potential health impacts of wireless communication have been ignored or obscured for decades by the telecommunications industry, which has implied that cell phones and other devices are safe because they comply with federal safety standards. However, these standards were established more than 20 years ago and were based on assumptions that have since been called into question by health research studies. The push to establish a 5G network, exemplified by SB 649, is based on a similarly unproven assumption: i.e., that round-the-clock exposure to 5G frequencies will not affect human health or the environment.Establishment of a 5G network will be irreversible, as will the pattern of near-universal exposure of California residents to high-frequency, as-yet-untested 5G electromagnetic radiation.”The letter can be downloaded at: http://bit.ly/LipsettSB649.

EMF Scientist Appeal Advisors Call for Moratorium on Policies 
for 5G “Small Cell” Antennas

 

The advisors to the International EMF Scientist Appeal submitted a letter to the Federal Communications Commission (FCC) in opposition to a proposed change in FCC rules that would allow rapid deployment of 5^th generation (5G) wireless infrastructure throughout the nation. A copy of the Appeal was appended to the letter.

5G involves transmission of millimeter waves which operate at much higher frequencies than currently used for cellular transmission (30 to 300 gigahertz). Because the range of these signals is limited (i.e., less than a football field), hundreds of thousands of new “small cell” antennas will be required in the U.S. The wireless industry wants to install these not-so-small cellular antennas on existing public utility poles.

The FCC intends to streamline the approval of these antennas which would further undermine the regulatory authority of cities and states over cell towers.

Meanwhile the wireless industry is lobbying for legislation in many states across the country that would limit local authority over cell antenna deployment.

Due to the concern that the FCC’s new rules will result in increased exposure to electromagnetic fields (EMF), the Appeal’s advisors oppose the new rules and call for a “public health review of the growing body of scientific evidence that includes reports of increasing rates of cancer and neurological diseases that may be caused by exposure to EMF from wireless sources.”

The Appeal reflects the concerns of 225 EMF experts from 41 nations about the impact of EMF exposure on public health. All of the experts who signed this appeal have published research in peer-reviewed scientific journals about the biologic or health effects of EMF.

According to the Appeal’s signatories, current national and international EMF exposure guidelines are obsolete and inadequate to protect human health and the environment. The FCC’s radio frequency guidelines were adopted in 1996.

The letter (dated June 9, 2017) is signed by the five advisors to the International EMF Scientist Appeal: Drs. Martin Blank, Magda Havas, Henry Lai, and Joel Moskowitz, and Elizabeth Kelley.

A 5G Wireless Future: 

Will it give us a smart nation or contribute to an unhealthy one?

Dr. Cindy Russell, The (SCCMA) Bulletin, Jan/Feb 2017

Safety testing for 5G is the same as other wireless devices. It is based on heat. This is an obsolete standard and not considering current science showing cellular and organism harm from non-thermal effects. There is a large gap in safety data for 5G biological effects that has been demonstrated in older studies including military.Recommendations
1. Do not proceed to roll out 5G technologies pending pre-market studies on health effects.
2. Reevaluate safety standards based on long term as well as short term studies on biological effects.
3. Rescind a portion of Section 704 of the Telecommunications Act of 1996 which preempts state and local government regulation for the placement, construction, and modification of personal wireless service facilities on the basis of the environmental effects so that health and environmental issues can be addressed.
4. Rescind portions of The Spectrum Act which was passed in 2012 as part of the Middle Class Tax Relief and Job Creation Act, which strips the ability city officials and local governments to regulate cellular communications equipment, provides no public notification or opportunity for public input and may potentially result in environmental impacts.
5. Create an independent multidisciplinary scientific agency tasked with developing appropriate safety regulations, pre-market testing and research needs in a transparent environment with public input.
6. Label pertinent EMF information on devices along with appropriate precautionary warnings.Dr. Russell provides a brief review of the research on millimeter wave bioeffects in this article: http://bit.ly/5GRussell.

5G cellular technology will employ much higher frequency microwaves than current cell phone technologies: 2G, 3G, and 4G.  These microwaves, known as millimeter waves, won’t penetrate building materials like the current technology which is why industry may need one cell antenna base station for every 12 homes.

But millimeter waves can affect your eyes and penetrate your skin.

When the Los Angeles Times reporter contacted me for the story below, I did a quick search and found several recently published articles examining biological effects of millimeter waves (see references below). This form of microwave radiation is most likely to affect our skin and neuronal cells in the upper dermis.

Moreover, widespread adoption of 5G cellular technology in the U.S. may have profound effects on our ecosystem by altering bacteria, possibly creating harmful bacteria that are resistant to antibiotics.

History has proved that we cannot trust the FCC and the FDA to protect our health from microwave radiation exposure.

I submitted an open letter to the FCC in July calling for “an independent review of the biologic and health research to determine whether the RF standards should be modified before allowing additional spectrum to be used for new commercial applications.”

Moreover, the FCC has ignored the 800-plus submissions that call upon the agency to adopt rigorous radio frequency standardsto protect the public’s health. Instead the agency maintains its 20-year old exposure guidelines that control only for heating or thermal risks. The FDA has ignored the thousands of studies that find nonthermal biologic effects, and the human studies that find a wide range of health effects including increased cancer risk and reproductive harm from exposure to low intensity microwaves.

In my opinion, precaution is warranted before unleashing 5G technology on the world. I suspect most of the 221 scientists who signed the International EMF Scientist Appeal (referenced in the article below), would support this assertion.

However, more research is also needed as specific characteristics of the millimeter waves (e.g., pulsing, modulation) to be employed in 5G cellular technology may be more important than the frequency or intensity of the waves in terms of biologic and health effects. The research funding must be independent of industry as conflicts of interest have been found to undermine the science in this field.

 Low-intensity millimeter waves 

used for pain therapy have side effects

The Russians have pioneered millimeter wave therapy (MWT) using low intensity millimeter waves to reduce pain including headaches, joint pain, and postoperative pain.

Although the following review paper documents some positive effects from short-term exposure to MWT, the authors note that there are side effects including fatigue, sleepiness, and paresthesia (an abnormal sensation, tingling or pricking [“pins and needles”] caused by pressure on or damage to peripheral nerves).

“We conclude that there is promising data from pilot case series and small-scale randomized controlled trials for analgesic/hypoalgesic effects of electromagnetic millimeter waves in frequency range 30–70 GHz. Large-scale randomized controlled trials on the effectiveness of this non-invasive therapeutic technique are necessary.” “In the studies reviewed the authors did not report any health-related side effects of MWT. Slight paresthesias, previously mentioned in several case reports and non-controlled case series (10,11), appeared in almost 50% of patients in studies where the effects of MWT were carefully described (21,27,28,31). The paresthesias were of short duration and reported as pleasant (‘warmth’) or neutral. General fatigue and sleepiness during the treatment sessions in almost 80% of the patients was a rather desirable side effect of MWT, as also described in previous reviews on biomedical effects of MWT (10,11,21,27,28).”From: Usichenko TI, Edinger H, Gizhko VV, Lehmann C, Wendt M, Feyerherd F. Low-intensity electromagnetic millimeter waves for pain therapy. Evid Based Complement Alternat Med. 2006 Jun;3(2):201-7. URL: http://www.ncbi.nlm.nih.gov/pmc/articles/PMC1475937/Little research is available on long-term exposure to millimeter waves (see below). Most of the studies referred to in this review paper did not modulate or pulse the carrier waves which will be required for information-carrying millimeter waves employed in 5G technologies. Prior research suggests that such waves will be more biologically active than pure sine waves.
