Opinion piece by non-expert in the field, failure to clearly present specific evidence (it's referred to, but not linked), pet subject for cranks. This is the kind of piece that makes the debate worse not better.
I think a healthy degree of skepticism is warranted with all the bogus 5G news about. But the author of the cited study, Professor John Frank[0], has past research in occupational and environmental epidemiology. That sounds like exactly the branch of research that would be involved in analyzing the risks of new technology.

This is actually a good question (rather than argument) for one reason: it's extremely simple to measure and debunk.
Go to a few places with good 5G and 4G coverage, measure EMF, compare, see nothing interesting and call it a day.

It's not that simple - frequency and modulation can make a difference in terms of biological interactions. Not that I believe there to be any harmful effects.
The article specifically mentions field strength alone exceeding health recommendations. This can easily be measured and debunked. Other claims will be addressed separately.
Frequency makes a difference, by affecting penetration and energy level. Signal modulation leads to harmonics and/or pulsing fields, but saying that modulation matters is quite misleading as it is simply frequency and power variation.
(For 5G, the end-result should end up being less energy as reduced cell size leads to reduced broadcast power on both ends of the connection, dissipated entirely as heat in a lower volume of tissue as penetration depth has dropped - a net win)

You haven't addressed a single point. Being an expert should help a person to make arguments, and sometimes does, but it's not an argument in and of itself.
The author being a non-expert in the field is useful to know. It doesn't have to be proof of something to be useful information in creating a more whole image. Even if that weren't the case, another point the parent made was that, in their opinion, the quality and tone of the article degrades conversation rather than contributing to it, which is another form of non-proof that is perfectly reasonable to express as an opinion. The parent may have spoken with a disrespectful tone, but "You haven't addressed a single point", is equally flippant and antagonistic. In fact, it's worse, since you're addressing it directly to a participant in the conversation.

You missed the exception he mentions. "IARC is the outlier in this respect, having determined in 2011 that EMFs are ‘possibly carcinogenic to humans’." (https://www.ncbi.nlm.nih.gov/books/NBK304630/)
They concluded that "With 'limited evidence' for carcinogenicity in humans based on an increased risk of glioma – a malignant brain tumour – among heavy users of mobile telephones, radiofrequency electromagnetic fields were classified as 'possibly carcinogenic to humans'"
This suggests more studies are required from a biological perspective in order to form an conclusions either way, which is his point in the opinion piece.
> Non-physicist discovers QAM, is confused. Again, no explanation given of why this might make a difference.
The full quote is;
"Furthermore, a comprehensive Canadian review of the same evidence states that some of the new RF-EMF technologies—such as innovations in radio frequency ‘pulsing,’ ‘polarisation’ and ‘modulation’—are so new that biological scientists have not been able to keep up—that is, no studies yet exist of these new technologies’ biological effects."

Yes, appeals to authority aren't much use in the present climate. So, that's why he needs to offer convincing evidence. It sounds like he offers none (I haven't read it, just relying on the summary above). "Pulsing" is not exactly a new idea in radio technology, is it? There's only like a century or more of radio systems that do that. As for modulation, does he know what the M in FM radio stands for? The claim that these are new innovations that "biological scientists can't keep up" is just obviously false on its face so what is he talking about?
If you plot rates of cancer on a chart you'll find it's actually stable or declining for decades:
https://progressreport.cancer.gov/sites/default/files/graphs...
Even as ever newer mobile protocols were rolled out (and really they're more like protocol upgrades than changes to the basic physics), cancer rates were stable for women and declining for men. If mobile tech caused cancers then we'd see it in the statistics by now, there's been plenty of time. We don't.
BTW this guy is an epidemiologist, and I've been ranting for the past 8 months on HN that these guys definitely have no idea what they're talking about. The standards in this field are just ludicrously low, so I'm not surprised at all to discover one of them thinks 5G causes cancer :(

My point was more that a physicist may be an authority on the technology itself, but would not necessarily be an authority on the affects it has on a biological system. That's why it has to be a multi-discipliniary approach rather than people being immediately dismissed for not being physicists. Why would you think that a physicist would be more of an authority on causes of human disease than an epidemiologist?
> The claim that these are new innovations that "biological scientists can't keep up" is just obviously false on its face so what is he talking about?
Ok his wording is pretty over the top here, but he literally points to a study which suggests as much.
> I'm not surprised at all to discover one of them thinks 5G causes cancer
It was actually the IARC working group for evaluating carcinogenic risks to humans. He was merely referencing their study and findings. And actually, once again, they're not saying that 5G causes cancer. They're saying that the evidence from their specific study suggests it might, but it's not conclusive, and that further studies are required to get better evidence either way.
Look I'm not saying that the evidence suggests 5G is harmful, I'm just taking issue with some of the specific dismissals presented above as I think they selectively cut out parts of the quotes that actually change their meaning somewhat.

I think they're likely more of an authority because physicists have been studying radio, EM energy and its effects on the atomic level for more than a century. Meanwhile, epidemiologists are not biologists. Look at Neil Ferguson, one of the world's most famous. His actual background isn't biology, it's ... physics!
If you want to get the views of biologists on the effects of EM on the body, then great! You'd want to talk to microbiologists about that. Physicists can probably also be informative, but epidemiologists can only look at graphs like the one I linked to previously. They're more or less data scientists, posing as disease experts, but what they're doing when you drill in is what anyone who knows R and a bit of stats could do.
The IARC finding seems to be phrased very ambiguously. I would read it as saying "we have no evidence, but absence of evidence is not evidence of absence". Which is true but not really helpful for moving the debate forward, as at some point absence of evidence does need to be taken as evidence of absence or else you'd be stuck in the precautionary principle of not doing anything forever.

Thanks for taking the time to write this!
Agreed wholeheartedly. I don't understand what it is about 5G that makes it such a popular target.
A meta-response: https://www.scimex.org/newsfeed/should-we-pause-the-5g-roll-...
Its precisely this level of discourse we need when such topics are raised. Thanks for the link!
Quite a weak article, i’m surprised this makes the bar for publication.
There’s a fair amount of contradiction too, it makes a distinction of “5G EMF” but then goes on to say 5G is loosely defined. So why 5G EMF and not just EMF? EMF in the Ghz to Thz range is not new. The only extra information conferred by adding 5G to the term is that we’re restricting the concerns to EMF at very low power levels (milliwatts).
I missed any links to let me follow up on the claims of harm found from non ionising radiation. I definitely want to see a bit more of the basis for those claims because if they’re based on findings at megawatts of RF energy then it’s not exactly useful, on the other hand if the findings are based on milliwatts of RF energy, that’s potentially a concern.
Side note: i don’t know if you’ve had a look at the 2.4GHz spectrum recently but i am amazed at the amount of emissions and i live next to mostly fields, genuinely surprised to see much in the way of emissions. Bluetooth beacons are a real stand out surprise, neighbours televisions, bathroom scales, all sorts of things that I wouldn’t expect to beacon when turned off.

I'm a complete ignorant in the matter, so will ask here.
Did we have any research like this prior to rolling out 4G? Or is this concern about 5G simply because the frequencies involved are much higher?
The frequencies may be higher but I believe the power is quite a bit lower - which is the point of 5G, yes ?
4G doesn't do anything weird compared to older mobile/cellular radio technology.
5G includes an order of magnitude higher frequencies, with far less penetration depth into humans. Thus the power is dumped into less volume. While the power levels involved seem very safe, we don't have the vast research body of cm waves.
But we do have a lot of research into the effects of radio on biological cells, though. Is the assumption here that less power but higher frequency would somehow have effects on the body that have previously never been noticed and for which there is no present theoretical basis? Is this theory falsifiable in any reasonable way?
After burning blasphemous 5G cell towers at the stake and setting traps for cell-site technician priests, anti-5G believers try proselytizing directly to the heathen.
The actual essay[0] is more tempered than the linked news release would suggest, and sounds like Professor Frank is hedging more than anything. The precise technology used is a complicated by 5G using different frequency bands between countries[1], even between providers [2]

On the one hand, it seems like to really understand the public health consequences, especially if some of the important effects are likely to be rare, one would likely need to see a large population exposed for a very long period of time (e.g. do babies who live their whole life around this tech develop some cancer when they're middle aged?) meaning the wait could be very long indeed, and probably by the end of it, engineers would have figured out something way better anyway.
But on the other hand, we do seem too prone to jump headlong into wide use of new tech without understanding all their impacts. Light pollution, climate change, microplastics inside everything including human placentas, leaded gasoline which may have driven a generation of higher crime rates, etc etc.
So in what cases _should_ we as a society wait a few decades to really vet something on a beta-testing population, if ever?

Like you said something like 5G causing cancer 30 years down the line would be very difficult to pinpoint as a cause of 5G, due to hundreds of other factors.
Either way, if you're worried about 5G, you should be worried about terrestrial TV airwaves as well.
Either way, if you're worried about 5G, you should be worried about terrestrial TV airwaves as well.
One of the "dangers" presented in the article is the greater density of masts but that means rather than having high energy masts blasting radio waves broadly over the population, we can have lots of low power ones. That seems like a better situation to me.
Not necessarily. Remember that field strength goes as the inverse square of the distance from the transmitter.
Suppose you need a certain minimum field strength for the receivers to work, and suppose it turns out that there is also a maximum safe field strength.
With a system based on a small number of powerful transmitters to cover an area you can usually place those transmitters in somewhat out of the way places that few people get near. You will have variation in field strength as you move around within the service area, but it won't be a lot of variation.
If I'm 1000 m from the transmitter and move 1 m closer, the field gets 0.2% stronger.
With a system based on a large number of weaker transmitters those transmitters need to be closer to where the receivers are to get the same minimum field strength throughout the same area. But with people much closer to the transmitters, there will be a lot more variation in field strength as they move around, so it would be harder to make sure that no places where people commonly go stays under your maximum.
If I'm 100 m from the transmitter and move 1 m closer, the field gets 2% stronger.
If I'm 10 m from the transmitter and move 1 m closer, the field gets 23% stronger.

There are a few problems with this argument though. It's technically correct, but:
1. All mobile protocols reduce signal strength to the lowest possible to reach the device. The field strength isn't some constant quantity. 5G is all about massive beamforming and super accurate power management. You're being targeted with an individual beam that's reduced the min strength possible to actually maintain radio contact. So moving closer doesn't imply a stronger 'field'.
2. Even with 4G it's totally common to have lots of base stations in the middle of cities, on rooftops, etc. It's not like they're all in the middle of empty fields today, far from it.

This totally neglects that in many cases, your smartphone is the closest transmitter. Having many base stations reduces the output power of your smartphone necessary to create the field power at the base station.
So I guess then it would come down to how often your phone transmits. If there is some sort of potential damage from non-ionizing radiation at power levels below those that cause heating damage (which has not been demonstrated), it is probably going to be a probabilistic thing. Probability of, say, cancer will be something like the integral over time of field strength above some threshold.
With the sparse high power tower network, that integral is low when you phone is not transmitting, but spikes way up when it is. With the dense low power tower network, you are trading a higher integral when your phone is not transmitting for a smaller spike when it is.
Figuring out which is better would require a lot more information than anyone here likely has (if it even matters at all...it is not proven that there is any danger in either scenario).

> Its inherent fragility means that transmission boosting ‘cell’ antennae are generally required every 100–300 m—which is far more spatially dense than the transmission masts required for older 2G, 3G and 4G technology, using lower frequency waves
I can see that it's necessary to place 5G masts more densely in order to deliver the promised transmission rates and coverage but it seems like a bad solution to a greater problem. Assuming the trend continues one would need even more cells to deliver 6G, 7G etc. Are there no other ways of increasing the bandwidth without placing a mast at every city corner?

The high frequencies are one of the techniques in 5G that enable faster data transmission. Another is beamforming: instead of broadcasting data in all directions, it is only sent in the direction of your smartphone. The thing is, there's no change for the receiving smartphone (same RF transmission power), just reduction in interference for others.
[edit: thereby, you can have more devices talking on the same frequency without disturbing each other, since they are separated by the "beams"]

Honestly, safety isn't my biggest complaint about 5g. We already have a wireless standard for short range networks: WiFi. It supports the same bands and multi antenna beam forming techniques. 5G means replacing open WiFi networks with networks controlled by a handful of companies paying fees to one or two equipment manufactures and pretty much exclusively Qualcomm in the US. Yes, the same Qualcomm that makes Android such a shitty platform by not publish GPU specs/driver code so you can throw out the broken code from the OEM.
I haven't seen use case proposals where 5G replaces home WiFis. It's often referred to as replacing the last mile to your home (i.e., your home router would talk 4G/5G to the operator and create a WiFi in your home). Also, some "small cell" approaches use WiFi and only do the access management using the mobile network.
WiFi on the other hand doesn't have any approaches for wide coverage, cell handover, or any kind of IoT applications.
I'd expect that smaller manufacturers emerge, especially for niche use cases outside consumer mass-markets.

I finally got a 5G signal near my home. The mast is further away than the 4G mast but I'm getting ~250Mbps down, and 60 Mbps up. Pings could be better though.
I can't wait for the closer 4G mast to be upgraded.
Stop this roll out over my dead body.

5G might never fully rollout, carriers would find electricity bills too high, if what the article suggested is even half true.
