5G safety and security

Is 5G completely safe and secure?
Is 5G radiation more or less dangerous than currently used 2G/3G/4G?

Just read this article and advice also other people to read (including two earler articles referenced). It tries to cover both the sides that say 5G is safe and 5G could potentially dangerous. But does it succeed in covering that properly?


Part 1 examined the potential ionization and thermal health risks posed by 5G. These are the conventional risks widely recognized and well controlled.

Part 2 examined electromagnetic (EM) effects. Here, the outcome was not so clear.

    5G has already been source lots bad quallty news articles – repeating vague marketing promises, technically incorrect and lots of FUD

  2. Tomi Engdahl says:

    A discussion of mmWave and terahertz signals would not be complete without mentioning health issues and the need for further study. On the biological front, the paper’s authors say that “heating is believed to be the only primary cancer risk” but much work is needed to “understand the biological and molecular impact of THz radiation on human health, even though THz is three orders of magnitude lower in frequency that ionizing radiation,” that being X-ray radiation.

    Orkney pupils kept at home over 5G mobile health fears

    Two families are keeping their children from going to a school in Orkney amid concerns about a 5G mast.

    But regulators insist there is no risk to public health.

    Its head of digital communications, Ian Walker, said in a letter to parents: “The equipment we’re using for the 5G broadcast radio trial is based around 4G technology, which is widely used across the UK, and the radio frequencies being used are the same that are used to broadcast TV.

    Cities Are Saying ‘No’ to 5G, Citing Health, Aesthetics—and FCC Bullying

    Those hawking specious safety concerns about the new technology have found common cause with some of America’s most powerful mayors

    Jack Tibbetts, a member of the Santa Rosa, Calif., city council, knew he had a problem. It was early 2018, and he’d started getting calls from constituents at opposite ends of the political spectrum. The common thread: cellular antennas going up next to their homes, causing concerns over property values and health.

  6. Tomi Engdahl says:

    It looks like many frear-mongrters follow the conspiracy theorist logic that if it new, slightly more complicated than you can understand and offers fast Internet, it must be lethally dangerous and no scientifically sound proof is needed for that.

    This is the logic that has been “successfully” applied to 3G, 4G, 5G and earlier WiFi.

  7. Tomi Engdahl says:

    Saying that we haven’t studied 5G long enough to see if it has adverse health effects is like saying we haven’t done enough studies to see if 40C water will cause burns. Like water temperature, we know at what frequencies electromagnetic radiation becomes dangerous, and it’s much higher than where 5G sits. https://www.androidauthority.com/5g-dangers-895776/ (Image:Jose Conejo Saenz (CC))

    Huawei believes banning it from 5G will make countries insecure

    Chinese giant warns of potential for backdoors in 6G thanks to AI.

    Huawei may be lacking 5G contracts and 100 former employees in Australia as a result of its banning in 2018, but one thing it is certainly not lacking is gumption.

    “Blocking companies from certain countries does nothing to make Australia any safer from cybersecurity issues — in fact it just makes things worse because they are not addressing the real issues on cybersecurity,” Soldani said

    The CTSO warned that thanks to Huawei being ahead of its rivals in 6G research, it could see how insecure those networks could potentially be as the attack surface becomes larger.

    “With the converge of management and control plane, AI will poses a significant impact on network security, as it might be exploited to launch more effective attacks, and in some scenarios, the security of AI systems is a matter of life and death,” he said

  9. Tomi Engdahl says:

    The following text from the article seems to be clear indication that we are dealing here with pseudoscience:
    “It seems that all types of human-made EMFs and electromagnetic radiation (EMR), in contrast to natural EMFs/EMR, are polarized. Polarized EMFs/EMR can have increased biological activity, possibly due to their ability to generate constructive interference forces, which magnify their concentrations at many places.”

  10. Tomi Engdahl says:

    Is the following paper science or pseudo-science?

    Polarization: A Key Difference between Man-made and Natural Electromagnetic Fields, in regard to Biological Activity

    “In the present study we analyze the role of polarization in the biological activity of Electromagnetic Fields (EMFs)/Electromagnetic Radiation (EMR). All types of man-made EMFs/EMR – in contrast to natural EMFs/EMR – are polarized. Polarized EMFs/EMR can have increased biological activity”

    “These features render man-made EMFs/EMR more bioactive than natural non-ionizing EMFs/EMR. This explains the increasing number of biological effects discovered during the past few decades to be induced by man-made EMFs, in contrast to natural EMFs in the terrestrial environment which have always been present throughout evolution”

    “A large and increasing number of studies during the past few decades have indicated a variety of adverse biological effects to be triggered by exposure to man-made EMFs, especially of radio frequency (RF)/microwaves, and extremely low frequency (ELF).”

    “Solar EMR intensity incident upon a human body ranges normally between 8 and 24 mW/cm2 (depending on season, atmospheric conditions, geographical location, etc) “

    Woman with ‘Wi-Fi allergy’ sleeps in $500 copper sleeping bag

    A woman who claims to be allergic to Wi-Fi is asking her hometown to discontinue their wireless internet to ease her condition

    Rosi Gladwell, 70, currently spends much of her time tucked inside a copper and silver thread sleeping bag, which cost her $500, to avoid electromagnetic fields (EMF) emitted by modern technology such as Wi-Fi and cellphones. She’s worried that the rollout of 5G in her current residence in the UK may cause irreversible damage to her health.

    Gladwell has spent hundreds on gear to protect her against electromagnetic radiation, such as a $250 radiation detector, according to the Sun. She frequently travels with her husband to her remote hometown in Spain via ferry, where she stays wrapped for 30 hours in a protective sheet. She launched a campaign in her hometown of Polopus, near Granada in Spain, in hopes they will shut down their citywide Wi-Fi, reports the Olive Press.

    She says she began to feel unwell six years ago — then suddenly felt better after switching off her Wi-Fi and cordless phones.

    Is 5G bad for your health? It’s complicated, say researchers

    Countries such as Switzerland, the UK and Germany are already rolling out next generation networks. 5G is projected to be 100 times faster than 4G and would allow new technologies such as connected cars and augmented reality to flourish. But despite the big promises, concerns about its potential health effects are also growing.

    So how different is 5G and could it impact our health? The reality, experts say, is complex.

    ‘We have been involved in hundreds of studies about electromagnetic radiation and human health,’ said Professor Niels Kuster, founder and director of the Swiss IT’IS Foundation. He was project coordinator for ARIMMORA, a study into the relation between the electromagnetic radiation emitted by power lines and childhood leukaemia.
    Non-ionising radiation can affect us in two ways, according to Prof. Kuster. Just like a microwave oven heats food using non-ionising radiation, telecom gear can do the same to the human body if it emits too much.

    ‘That’s well understood scientifically and there are clear safety guidelines for this,’

    We have less of an understanding of the second way in which non-ionising radiation can affect us – how it interferes with us biologically, says Prof. Kuster.

    Prof. Kuster says that there is very little clear scientific evidence showing that radiation causes the exhibited symptoms associated with electrohypersensitivity. The World Health Organization noted that double-blind studies have been unable to establish a correlation.

    The evidence around cancer is, however, more difficult to interpret. Several large-scale epidemiological studies showed mixed results.

    ‘no increase in risk of glioma or meningioma was observed with use of mobile phones’

    Some animal or lab-based cell studies have shown certain negative health effects from radiation. This eventually led the International Agency for Research on Cancer (IARC) to classify electromagnetic radiation as ‘possibly carcinogenic to humans.’

    This may sound scary but refers largely to uncertainty in the results.

    European risk report flags 5G security challenges

    European Union Member States have published a joint risk assessment report into 5G technology which highlights increased security risks that will require a new approach to securing telecoms infrastructure.

    But the report flags risks to 5G from what it couches as “non-EU state or state-backed actors” — which can be read as diplomatic code for Huawei. Though, as some industry watchers have been quick to point out, the label could be applied rather closer to home in the near future, should Brexit comes to pass…


  14. Tomi Engdahl says:

    Amid security concerns, the European Union puts 5G — and Huawei — under the microscope

  15. Tomi Engdahl says:

    Depending on who you believe 5G can cure or kill us. Or it can help business to grow or be quite useless for the applications it is marketed for.

    The only thing that you can be sure of is that there are lots of fake news on 5G everywhere.

  16. Tomi Engdahl says:

    5G is non-ionizing radiation. If that killed people, the golden age of radio would have wiped out all life on Earth.

    Ericsson 5G Blackbox

    Ericsson is offering the hackers a unique opportunity to test state-of-the-art next-generation telecom equipment that enables use cases like smart manufacturing and remote health care. This challenge offers a unique opportunity to get your hands-on Ericsson’s 5G radio infrastructure to see if you can hack it. Can you find any vulnerabilities?

    “The truth about mobile phone and wireless radiation” — Dr Devra Davis

    The Lecture
    What are the health effects of mobile phones and wireless radiation? While Australia has led the world in safety standards, including compulsory seat-belt legislation, plain packaging on cigarettes, and product and food disclosure legislation, it falls behind in addressing the significant issues associated with mobile phone use. In this Dean’s Lecture, epidemiologist and electromagnetic radiation expert, Dr Devra Davis, will outline the evolution of the mobile phone and smartphone, and provide a background to the current 19 year old radiation safety standards (SAR), policy developments and international legislation. New global studies on the health consequences of mobile/wireless radiation will be presented, including children’s exposure and risks.

    As 5G Rolls Out, Troubling New Security Flaws Emerge
    Researchers have identified 11 new vulnerabilities in 5G—with time running out to fix them.

    It’s not yet prime time for 5G networks, which still face logistical and technical hurdles, but they’re increasingly coming online in major cities worldwide. Which is why it’s especially worrying that new 5G vulnerabilities are being discovered almost by the dozen.

    The researchers from Purdue University and the University of Iowa are detailing 11 new design issues in 5G protocols that could expose your location, downgrade your service to old mobile data networks, run up your wireless bills, or even track when you make calls, text, or browse the web. They also found five additional 5G vulnerabilities that carried over from 3G and 4G. They identified all of those flaws with a new custom tool called 5GReasoner.

    One purported benefit of 5G is that it protects phone identifiers, like your device’s “international mobile subscriber identity,” to help prevent tracking or targeted attacks. But downgrade attacks like the ones the researchers found can bump your device down to 4G or put it into limited service mode, then force it to send its IMSI number unencrypted.

    The researchers submitted their findings to the standards body GSMA, which is working on fixes.

  21. Tomi Engdahl says:

    Then there was THIS ” brilliant ” decision.

    NOAA, NASA, and the Navy have raised concerns with Congress that the new 24 GHz radio frequency band for 5G may interfere with critical water vapor sensors on US weather satellites. The 24 GHz band is one several new mmWave bands the FCC is making available for mmWave 5G service. Verizon and AT&T are deploying 5G this year in the 28 and 39 GHz mmWave bands. The FCC’s auction of the 24 GHz band is expected to conclude on May 28th. The weather sensors in question operate at 23.8 GHz. The new 24 GHz band being auctioned spans 24.25 — 25.25 GHz

  22. Tomi Engdahl says:

    Protestors also cite the lack of scientific evidence showing that 5G signals, specifically those transmitting in the millimeter wave region of the electromagnetic spectrum, are safe. Today’s mobile devices operate at frequencies below 6 gigahertz, while 5G will use frequencies from 600 megahertz and above, including the millimeter wave bands between 30 GHz and 300 GHz.

    Enough concern has been raised about 5G that some cities have cancelled or delayed the installation of the base stations.

  23. Tomi Engdahl says:

    “Microwaves sit 100 times below Australia’s EME safety limit, and 5G is one or two orders of magnitude safer.”

    IEMI – Threat of Intentional Electromagnetic Interference

    As our cities, our transportation, our energy and manufacturing – our everything – increasingly embrace Internet of Things (IoT) and Industrial Controls Systems (ICS), securing its underlying cyber-physical systems (CPS) grows ever more crucial. Yet, even among engineers and cybersecurity specialists, one potential attack trajectory is often overlooked: Intentional Electromagnetic Interference (IEMI).

    ICS and IoT – digital systems that run today’s modern society – rely on changes in electrical charges flowing through physical equipment.

    electromagnetic wave-based communication can be disturbed or stopped by external electromagnetic interference (EMI) sources causing unpredictable results.

    The industry has established a number of legal requirements and standards for electromagnetic compatibility (EMC). The goal is to ensure correct operation of devices in common electromagnetic environment and resilience to unintentional EMI. With the exception of aircrafts, these EMC requirements are typically not sufficient to protect against intentional electromagnetic interferences (IEMI) generated by malicious actors in order to disrupt performance of electronic equipment. This might invite terrorists, criminals and other adversaries to intentionally interfere or damage critically important CPSes such as telecommunications, power networks, financial systems, medical care, broadcast media, industrial plants, traffic control systems, food and water supply, critical manufacturing, mass transit and others.

    IEMI was until the turn of the millennium essentially a military concern but have since then generated quite a lot of interest in the civil arena. Capabilities of IEMI attackers have been growing steadily over the last two decades. On the other hand, growing complexity and distribution of CPSes and decreasing power requirements for the devices that make up the Internet of Things (IoT) make it increasingly possible to connect more and more components of our physical world to monitoring and control devices. This provides a growing pool of increasingly vulnerable targets for attackers. Together, these few trends increase the threat of IEMI attacks exponentially.
