Are community concerns over the 5G network rollout based on unfounded anxiety or valid evidence?

by Don Maisch PhD


5th generation (5G) wireless technology, as the name indicates, is the next generation wireless communication network from 4G and 4G LTE. Once fully implemented it will predominantly operate in the millimetre (mm) radiofrequency band which will allow much higher data transfer necessary for driverless vehicles, the Internet of Things (IoT), faster video downloads as well as other applications, including military. The downside of 5G mmWave, however, is that the signals do not penetrate objects readily such as buildings and foliage, in comparison to the lower frequencies. This necessitates a far denser network of 5G small cell antennas which will be mounted on power poles, light poles, street furniture, bus shelters, etc. which in many cases will be close to homes, workplaces and public areas. In some cases internal antennas in buildings will also be used.  This will result in higher chronic radiofrequency exposures to humans in these areas. The high number of small cells needed for an effective 5G network is causing community disquiet and that, combined with many scientific unknowns about the possible biological effects of prolonged exposure to mm waves, is resulting in increasing community opposition in Australia and internationally. As community opposition is most likely going to increase as 5G infrastructure continues to be rolled out nationally, the question arises: Is this opposition to 5G warranted or not?

5G community concerns in Australia

The Blue Mountains

On January 29, 2019, the Katoomba Council in the Blue Mountains, NSW, voted unanimously to acknowledge serious community concerns over the coming rollout of 5G technology and to investigate these 5G concerns further. Mayor Mark Greenhill said after the meeting that there was “significant community concern” (1) and that the council would be writing to various government ministers in order to help clarify the issue (2).

In response to this, Professor Simon Chapman from the University of Sydney, used a very ‘broad brush’ in dismissing community 5G concerns by bringing in other contentious issues in attempting to picture 5G concerns as just another example of anti-technology risk-phobic alarmism.

The most elementary test of the hypothesis that mobile phone and other electronic appliances like WiFi may give you brain cancer has repeatedly fallen at the first and most obvious hurdle. If they cause brain cancer, where are all the bodies? Ever since the nineteenth century we have seen pockets of anxiety about health from train travel, ordinary phones, radio, computer screens, electric blankets, power lines, WiFi, smart meters and wind turbines. Meanwhile life expectancy is longer than it has ever been in history. (3)

And quoting from Chapman’s blog:

Mobile phone alarmists are a relentless (small) lobby group who are risk-phobic about almost every new form of communication. Every time there’s a new generation of cell phone or electronic technology, they crank out the same fear-mongering stuff.  Cult-like, they wake every morning, to spread the word about the deadly rays they believe are being foisted on the world by the evil telecommunications industry. They follow in the hallowed footsteps of those in history who raised health alarms about railway travel, electric light, ordinary phones, radio, TV, electric blankets, computers, microwave ovens, wind turbines and solar roof cells etc. Some are also anti-vaccination (e.g.: this is one of their US queen bees). (4)

Ryde, Sydney

In early January 2019, a group of over 100 residents of the suburb of Ryde signed a petition to have small cell 4G antennas (which will later be upgraded to accommodate 5G infrastructure) removed from the Ryde residential area. Unlike larger towers, small cell antennas do not need planning approval under the Federal telecommunications act. Sue Cappadonna, spokesperson for the group, said “We don’t want it here, it causes us great anxiety that this thing is going to be running 24/7”. (5)

In response, Dr. Geza Benke from Monash University’s Department of Occupational and Environmental Health said that residents living near small cell boxes (antennas) had nothing to worry about. He then made a rather surprising statement that:

The exposure which people get from these antenna (small cells) is no more than you would get from a large antenna. . . over the next two years the small cell boxes would become commonplace, as they are considered a critical component of “filling in the gaps” for the high-speed 5G network…” (6)

As “these antenna” can be erected without local authority and community permission on bus shelters, light poles, power poles, etc. close to homes in residential areas, it is questionable whether concerned residents would be put at ease by Benke’s statement.

Responding to the above ABC News item about the Ryde community 5G concerns, Adam Verrender, a PhD Student, under the supervision of Rodney Croft at the Australian Centre for Electromagnetic Bioeffects Research (ACEBR), wrote a reply for the ABC News on January 9, 2019. His article started out with his claim that:

 Decades of scientific research has found no evidence of any adverse health effects [from mobile phones] but still the public remains concerned. Even studies looking at long-term damage, such as brain cancer, have not found evidence of increased harm. (7)

Such a disingenuous claim of “no evidence” is at odds with the decision of the International Agency for Research on Cancer (IARC) which, in 2011, classified radiofrequency emissions from mobile phones as a possible human carcinogen, based on the 13 nation Interphone study on mobile phone use (8).

Verrender also claimed in his article that the continuing debate over adverse health effects from “phone tower anxiety” is being “fuelled by misinformation, scepticism and a complex psychological phenomenon known as the nocebo effect”. As a result of this according to Verrender “it’s little wonder this contentious issue persists, particularly given wireless technologies are so pervasive”. (9)

As for evidence that any adverse effects from radiofrequency exposure, such as electro-hyper-sensitivity (EHS) are purely psychological, Verrender mentions in his article the provocation study designed by ACEBR which supported the view that a complex psychological phenomenon, the nocebo effect, could explain the condition (EHS). What he failed to mention was that the ACEBR study finding was based only on three subjects and therefore lacked sufficient statistical significance to back up his claim (10, 11).

As for the scientific validity of the ACEBR provocation study, in 2013 CSIRO scientist and statistician, Dr. David McDonald conducted an analysis of the proposed ACEBR provocation study. He concluded in part:

As it stands the proposed experimental design and statistical analysis cannot be used to achieve the stated aim. The scientific and statistical shortcomings of the proposed [study] are each serious flaws in themselves and their cumulative impact and interaction render the proposal scientifically indefensible. All of them need to be corrected in a major revision of the proposal. (12)

According to Dariusz Leszczynski (13) who has studied McDonald’s full critique and later versions of the ACEBR test protocol, he saw no changes and considered it as an exact repetition of the earlier design (14). Leszczynski has written extensively about the many weaknesses on provocation testing, including that designed by ACEBR, and has published an open letter on the weaknesses of EHS provocation research (15).

A sampler of growing international opposition to 5G network rollouts

In 2017 an international 5G Appeal was launched by scientists and doctors who are calling for the EU to halt the roll out of 5G due to serious potential health effects from the technology. As of April 24, 2019, 231 scientists and medical doctors have signed the appeal (16).

  • March 24, 2019: Portland Oregon city officials in the US stated their opposition to the installation of 5G networks around the city, supported by the mayor and two commissioners. The city officials considered that 5G health risks were not well enough understood to warrant installations (17).
  • March 28, 2019: Florence, Italy, applied the precautionary principle by refusing permission for 5G infrastructure and referring to “the ambiguity and the uncertainty of supranational bodies and private bodies (like ICNIRP)”, which “have very different positions from each other, despite the huge evidence of published studies”(18).
  • March 28, 2019: The Roman district “XII Municipality of Rome” voted against allowing 5G trials, with other districts expected to follow. Other motions to stop 5G are expected in the four regional councils, one provincial council and other municipal councils of Italy (19).
  • April 1, 2019: Plans for a pilot project to provide high-speed 5G wireless internet in Brussels have been halted due to fears for the health of citizens, Environment Minister Céline Fremault said that “The people of Brussels are not guinea pigs whose health I can sell at a profit. We cannot leave anything to doubt” (20).
  • April 4, 2019: The House of Representatives of the Netherlands expressed its concern over the possible health risks of radiation from the new 5G network. Political parties want to know as a matter of urgency what the dangers are before 5G is rolled out on a large scale (21).
  • April 5, 2019: The California Supreme Court Justices unanimously upheld a 2011 San Francisco ordinance requiring telecommunications companies to get permits before placing small cell antennas on city infrastructure (22).
  • April 8, 2019: A petition asking the German Parliament to stop the award of 5G frequencies has reached 54,643 signatures, surpassing the quorum, according to an environmental campaign group called ‘Diagnose: Funk’. The German Parliament may decide to suspend the procedure to award 5G frequencies based on “scientifically justified doubts about the safety of this technology”, according to the petition (23).
  • April 9, 2019: Switzerland’s 3rd largest region, Canton of Vaud adopted a resolution calling for a moratorium on 5G antennas until the publication of a report on 5G by the Swiss Federal Office for the Environment (24). Other cantons may follow with further moratoriums (25).
  • April 11, 2019: Geneva adopted a motion for a moratorium on 5G, calling on the Council of State to request WHO to monitor independent scientific studies to determine any possible harmful effects of 5G.(26)
  • April 20, 2019: Switzerland announced that it will monitor 5G health risks as a result of a pushback from citizens who claim that 5G emissions present dire health risks (27). Four cantons have now stopped 5G networks, Jura, Geneva, Vaud and Neuchâtel. Comprising 1.5 million people. However, the majority state-owned Swisscom defied these cantons by activating 5G stations in 102 locations by upgrading existing antennas installed for previous generations of wireless technology (28, 29).


So, what are we to make of all this. Are there valid concerns over the rollout of 5G technology, or is this all needless worry from a misled public, as suggested by those connected with ACEBR and Prof. Simon Chapman?

Validating community concerns

In early 2019 the Policy Department for Economic, Scientific and Quality of Life Policies Directorate-General for Internal Policies (European Commission), was commissioned by the EC’s Committee on Industry, Research and Energy (ITRE) to prepare an in-depth analysis on the deployment of 5G technology in the EU, the USA, China, Japan, the Republic of Korea, Singapore and Taiwan.

This report, titled 5G Deployment: State of Play in Europe, USA and Asia, was published in April 2019. The authors point out that the global roll out of 5G is not a short-term race and that “5G is more complex than previous wireless technologies and should be considered as a long-term project to solve technical challenges and develop a clear business case”.

As for those “technical challenges” this is mentioned in the executive summary (excerpt):

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 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. (30)

Unpredictable propagation patterns

To visually understand what is meant by those unpredictable propagation patterns mentioned in the EC 5G report it is worthwhile examining an Ericsson PowerPoint presentation, titled Impact of EMF limits on 5G network roll-out.

The presentation was prepared by Christer Törnevik, Senior Expert, EMF and Health, Ericsson Research, Stockholm Sweden. The presentation was given at The International Telecommunications Union’s (ITU) Workshop on 5G, EMF & Health, Warsaw, Poland on December 5, 2017.

In part, the presentation concluded that with increased human exposure levels from 5G antennas, EMF exposure compliance in some nations will be difficult. To quote: “In countries with EMF limits significantly below the international science-based ICNIRP limits the roll-out of 5G networks will be a major problem”(31).

The 5th Asian and Oceanic IRPA Regional Congress on Radiation Protection (AOCRP-5) Melbourne, Australia, May 20 – 23, 2018

At a recent scientific conference by the Australian Radiation Protection and Nuclear Safety Agency two expert presentations gave reason to pause in the rapid roll out of 5G millimetre waves. The first was by Dr. Dariusz Leszczynski, adjunct professor of biochemistry, University of Helsinki, Finland and chief editor of Frontiers in Radiation & Health, Lausanne, Switzerland. In his presentation, titled 5G Millimetre-Waves Health & Environment, Leszczynski examined the serious limitations of biomedical research on millimetre waves but from what studies that are available, it should cause great concern. He specifically called for the urgent need for research on 5G millimetre waves because of the rapidly ongoing deployment of 5G technology (32).

Another presentation was by Dr. Andrew Wood, School of Health Sciences, Swinburne University of Technology, Melbourne. Titled ‘What is the current status of research on mm-Wave frequencies’, Wood mentioned two areas of uncertainty with 5G radiation:

  • Skin and eyes are regions of concern in regard to 5G frequencies (6-60 GHz) and beyond.
  • Could be resonant enhancement absorption due to skin structures.(33)

Possible effects on trees and foliage

Another possible problem specific to 5G millimeter emissions is that they can be disrupted or blocked by trees and foliage, especially after rain. This creates a potential problem for suburban streetscapes. Will residents have to choose whether they prefer a pleasant green environment or great download speeds (34)?

The potential problem of trees and 5G reception has not escaped Telstra’s notice. To quote from Mike Wright, Telstra’s managing director of networks:

“Telstra is also funding research into whether uniquely Australian obstacles – including flora – will disrupt 5G signals, which occupy a higher frequency and don’t travel as far as other mobile signals. “Something that seems to be unique to Australia, and we found with earlier standards, is how gumtrees impact those radio signals and the way they get from the radio tower to the end user”. (35)

In a September 2018 New Zealand court case the judge ruled, in relation to a property owner’s trees blocking a neighbour’s wi-fi reception, that “undue interference with a wi-fi signal caused by trees could constitute an undue interference  with the reasonable use and enjoyment of an applicant’s land for the purposes of s335 (1)(vi) of the {property law} Act.” Lawyer and IT specialist Rick Shera said of the case: “This decision is interesting because it finds that, in some circumstances, neighbour A can require tree trimming, or removal, repair or alteration of a structure, on neighbour B’s land, where the trees or structure unduly interfere with the neighbour A’s wireless connectivity.” (36)

As 5G transmissions may be more prone to being blocked by trees than wi-fi signals what will be the legal implications if this turns out to be an issue?

An important question: Can 5G phased array antennas generate Brillouin precursors?

In early 2002 the New York based technical publication, Microwave News published an examination of a rather arcane topic: Brillouin Precursors. The issue at that time was non-ionising radiation from the phased array PAVE PAWS radar facility at Cape Cod, Massachusetts, USA.  A Brillouin precursor is a very fast pulse of radiation, which when it enters the human body, may generate a burst of energy that can travel much deeper than predicted by conventional models.

In a Microwave News interview with Professor Kurt Oughstun (37), he explained how Brillouin precursors are generated by phased array radar antennas. When asked, “Are Brillouin precursors unique to PAVE PAWS radiation?”, Oughstun replied:

“No – not at all. As data transmission rates continue to increase, wireless communication systems will approach closer to and may, at some time in the not-too-distant future, exceed the conditions necessary to produce Brillouin precursors in living tissue. (38)

It must be pointed out that it is not known if Brillouin precursors would be created by 5G phased array antennas as no research has been done – so this is hypothetical. However, considering the uncertainties mentioned in the recent EC report on 5G, mentioned earlier, this possibility should be investigated:

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.

Concluding thoughts

What is apparent in this controversy is that the public’s perception of risk and that of some experts defending the technology is at wide variance. The assurances of a complete absence of risk from 5G networks coming from these experts is not reflected in what is known about the many uncertainties which exist with 5G technology and speaks more about their own ignorance than that of concerned communities.

What we are seeing here is an example of what has been defined as technological fundamentalism. To quote from Robert Jensen:

Technological fundamentalists believe that the increasing use of evermore sophisticated high-energy, advanced technology is always a good thing and that any problems caused by the unintended consequences of such technology eventually can be remedied by more technology. Those who question such declarations are often said to be “anti-technology,” which is a meaningless insult. All human beings use technology of some kind, whether stone tools or computers. An anti-fundamentalist position is not that all technology is bad, but that the introduction of new technology should be evaluated carefully on the basis of its effects—predictable and unpredictable—on human communities and the non-human world, with an understanding of the limits of our knowledge.(39)

  4. Corrigendum: The 4th sentence of my Ryde paragraph should read – “The trend of replacing macro cells with small cells is analogous to the trend to replace high-wattage centre of the room light fixtures with multiple low-wattage pot lights.”

  5. “Are community concerns over the 5G network rollout based on unfounded anxiety or valid evidence?” This is not a binary question that can be answered with a simple yes or no

    No scientific data supports definitive answers to questions about the existence or nonexistence of health risks related to electromagnetic fields. More research to produce more reliable information is needed before any firm conclusions can be drawn. However, it can be said is that many scientists on both sides of the question agree we are dealing at most with rare diseases and an increased risk that is very small, especially compared with life’s other everyday risks.

    In the case of the concerns of the Blue Mountain community, they are probably unfounded anxiety. I say this because the 3.5 GHz frequency band falls between the two Wi-Fi bands and has been used in WiMAX applications for a few decades. There is no mystery as to what it can and cannot do; and there is no reason to find it any scarier than existing 3G & 4G exposure.

    As for the Ryde, Sydney concerns of increased exposures from small cells: probably unfounded! As Dariusz and others have pointed out, a lot of the exposure to people comes from their own wireless device close to the body – and the amount of this exposure is controlled by the quality of the base station signal. A strong signal from a nearby transmitter means that the mobile output power will be reduced. And many small cells provide a more homogenous distribution of the signal. The trend of replacing small cells with macro cells is analogous to the trend to replace high-wattage centre of the room light fixtures with multiple low-wattage pot lights. There is every reason to believe that multiple small cells will lead to lower personal exposure.

    And your “important question: Can 5G phased array antennas generate Brillouin precursors?”
    Firstly, as frequency is increased the absorption is reduced. At mmWave frequencies almost all of the signal will be reflected, with only a tiny amount absorbed by the outermost layer of skin – and any resulting heat will be dissipated as fast as it is absorbed. Furthermore, 5G signals are not pulse-modulated. So, this concern is also based on unfounded anxiety.

    By the way, all panel and patch antennas are ‘phased array’ antennas. This not not a new thing for 5G!

  6. Why is it so hard to understand that emf at certain frequencies can cause harm…we are bio electric beings and even micro volts can have an effect on the human (and animal) nervous system?Anyone overlooking possibilities of damage is very suspicious (are they punting for the industry?)
