Section/link on problems with 5G[edit]

Hi, I mentioned elsewhere that I looked in vain for anything on potential problems with 5G. This is to signal that, if I get a chance, I hope to start a section, or at least a link, to reputable sources that have flagged these issues: for example the danger that trees that get in the way may be destroyed, aesthetic issues around the proliferation of masts, possible health issues, etc. I intend to use only serious mainstream sources (e.g. newspapers of record) and not amateur blogs and the like. It would save me a lot of time and effort if anyone who has a problem with that idea could let me know before I spend the time on the research, and also indicate what kind of literature is acceptable, as well as what isn't. (I don't have a technical background so I'm winging it a bit on this, but I'll do the best I can.) Thanks.Be-nice:-) (talk) 22:21, 15 March 2019 (UTC)

Some problems that you mentioned were the subject of raving edits to this page that required freezing it. Rather, since much of what you propose presupposes a lot of things that are not specific to 5G, they would fit better in other pages or in a new page altogether. ebahapo (talk)

Thanks :-) That's helpful to know. I wasn't up to speed on the editorial history. The following is the kind of thing I wss thinking of, from the website of RTE, the state broadcaster in Ireland (equivalent of the BBC). The article is balanced, directly relevant to 5G, written by a professor in the area, mentions the issues without over-egging them (as far as I can tell) and cites relevant sources. Would that pass muster, and if not why not? As I said, I'm not an expert in the area so I can only go on what seem to be appropriate sources (talk) 14:39, 16 March 2019 (UTC)

No, it does not pass muster. Microwaves are not ionizing radiation (implying something that is emitted by rays) and therefore does not cause cancer, unlike ionizing radiation, like β rays. Moreover, 5G will also use low frequency microwaves (below 6 GHz), just like 4G and 3G, and, decades after human exposure to such microwave radiation, no ill effects have been observed. On the other hand, 5G will additionally use high frequency microwaves (above 24 GHz), near and into the mm-wave range. Much of similar alarmist reports focus on this range, but, between the two, this is actually the least concerning. The fallacious argument stems from the fact that 5G in the mm-wave range will necessitate a higher density of antennas to cover an area with signal. The reason is that mm-waves are absorbed by water vapor in the atmosphere, which rapidly decreases their range. Thus, with a shorter range per each antenna, more antennas are needed to cover a given area than with lower frequencies. However, regardless of the number of antennas or the frequency used, typically the power emitted by the antenna will be less than 10W, the power reaching the user equipment will be in the range between fW to µW and the power emitted by it will be less than ¼W. As a matter of fact, mm-waves are more likely to be mostly absorbed by the skin, unlike low frequency microwaves, which can reach into the muscles. Still, the effect of microwaves being absorbed by living tissue is increased temperature and never genetic mutation. Yet, unlike meat in a microwave oven, whose power is up to 1500W, the temperature increase will be minute and innocuous. I suggest that you read on Electromagnetic radiation and health and Mobile phone radiation and health and, should you still desire to contribute to the discussion, you do it those pages first. ebahapo (talk) —Preceding undated comment added 02:13, 17 March 2019 (UTC)

Thanks for your reply. I'm a bit flummoxed here. Obviously I can't begin to argue the case re the technicalities, but I'm puzzled why an article (a) written by a professor in the area and (b) in a reputable publication, would not be regarded as at least having arguable status in this entry. Are you saying that anything that raises health issues is ipso facto to be dismissed without a hearing, even if it's written by Einstein (or whoever the equivalent may be in this area)? But leaving aside the health issues, there are in any case other concerns. As you write yourself: "Thus, with a shorter range per each antenna, more antennas are needed to cover a given area than with lower frequencies." This would potentially raise aesthetic, cultural and environmental issues (extraneous to health matters) which are surely worth noting and including in the discussion. So if I can source material critical of the proliferation of antennae, is it appropriate to include it in the entry, and if not, why not?Be-nice:-) (talk) 22:37, 17 March 2019 (UTC)

Neither WP:NONFACT nor WP:SOAPBOX will be allowed in this page. — Preceding unsigned comment added by Ebahapo (talkcontribs) 17:20, 18 March 2019 (UTC)
Well, first - the professor isn't writing in his area. He's a professor of 'Cyber Security' who's writing about medicine here. Second, Wikipedia has special sourcing requirements for medical claims precisely because the popular media gets this kind of thing wrong so frequently. - MrOllie (talk) 17:30, 18 March 2019 (UTC)

OK, so if I can source material from medical experts in reputable publications who question 5G, is that OK? (Though I imagine that people with expertise in both medicine and mobile phone technology are kind of scarce...) Apart from the medical issues though, is there any objection to citing issues that have been raised about the potential proliferation of antennae, from (e.g.) an environmental, aesthetic or cultural POV? NB I do not intend to go down the "Soapbox" road, insofar as I understand the policy/guidelines, simply to note the objections that are out there. Thank you. Be-nice:-) (talk) 23:54, 18 March 2019 (UTC)

Again, I encourage you to contribute what you find at Mobile phone radiation and health and Cell site and, if it's accepted there (cf. WP:PRIMARY, WP:NOR, WP:NOTABILITY, WP: NPOV ), I'd be glad to link to it here. — Preceding unsigned comment added by Ebahapo (talkcontribs) 02:20, 19 March 2019 (UTC)

Thanks, that looks like a useful site. I'm wondering though why this article doesn't link to it already (?) On a separate matter, can I assume that there is no objection to including non-health issues that have been raised to 5G in this article, e.g. environmental, aesthetic or cultural, due to the proliferation of antennae?Be-nice:-) (talk) 13:37, 19 March 2019 (UTC)

Maybe someone will object, maybe not. Without seeing the proposed source it's hard to know. - MrOllie (talk) 13:47, 19 March 2019 (UTC)
Please, see the See also section. Also, I do not think that this article is the right place for aesthetic issues of cell sites. Again, as I pointed out above, contribute your research in Cell site and, after it's integrated there, though I don't pretend to speak for all, I'd be glad to link to it here. — Preceding unsigned comment added by Ebahapo (talkcontribs) 19:48, 19 March 2019 (UTC)

Here is an example of the issues raised re the proliferation of antennae, from the conservative British newspaper The Telegraph: (There is also a lot of stuff on the Internet re the supposed connection between preparation for 5G and widespread tree-felling in the UK and ROI, though I've struggled to find any "respectable" sources on the tree issue, i.e. not self-published blogs and the like. There is certainly an inordinate amount of tree-felling going on, and 5G is certainly being rolled out, though whether there is any connection between the two is another matter).Be-nice:-) (talk) 00:00, 20 March 2019 (UTC)

This article is a perfect example of WP:SOURCE. And, as all the other sources you mentioned, it's written by clueless authors. For instance, it assumes that 5G always requires a dense antenna deployment, which is only true for mm waves. 5G can and will be deployed on the same frequencies and masts as 2G, 3G, 4G as well. Therefore, in rural areas, there just is no ROI in deploying 5G in mm waves. As a matter of fact, it seems that these are the only sources that motivate you. If these are the kind of sources that you are using in your research, then it's not research at all and its results have no place in an encyclopedia, but in Reddit, 4chan, etc. Again, no WP:SOAPBOX. Ebahapo (talk) 16:48, 20 March 2019 (UTC)

From WP: SOURCE: "Other reliable sources include:

University-level textbooks Books published by respected publishing houses Magazines Journals Mainstream newspapers"

The Telegraph is undoubtedly a mainstream newspaper, though as it happens I don't normally agree with its politics. It seems to me that you have a somewhat dogmatic view of what should and shouldn't be included here. Anyway, I've better things to do than to get into a Wikipedia squabble. Have a nice day.Be-nice:-) (talk) 01:36, 27 March 2019 (UTC)

I remind everyone, neither Ebahapo nor anyone else has the authority to WP:OWN this page. The whole section above beginning with "No, it does not pass muster. Microwaves are not ionizing radiation (implying something that is emitted by rays) and therefore does not cause cancer, unlike ionizing radiation, like β rays. " is WP:OR without any sources. I assess the text in that section as bullying. I certainly will be keeping an eye open here. 18:21, 27 March 2019 (UTC)

Pardon me, but I assumed that the links at See also section provided enough support for my statement above. Specifically, Mobile phone radiation and health, from Electromagnetic radiation and health. I also recognize that I fell into WP:POVRAILROAD, for which I apologize. — Preceding unsigned comment added by Ebahapo (talkcontribs) 21:00, 27 March 2019 (UTC)
this quote from WP:FRINGE explains why it would be (and therefore is) quite wrong to summarily exclude alternative scientific theories about the effects of 5G: “Alternative theoretical formulations from within the scientific community are not pseudoscience, but part of the scientific process. They should not be classified as pseudoscience but should still be put into context with respect to the mainstream perspective. Such theoretical formulations may fail to explain some aspect of reality, but, should they succeed in doing so, will usually be rapidly accepted.“ Boscaswell talk 19:36, 18 April 2019 (UTC)

Reading this whole talk I get the impression that owning content and shooting down concerns is a priority. Also, seeing "Radiation FEARS" and "Espionage FEARS" as index points seem very biased. When looking up a hot topic like 5G, one would expect at least a broad spectrum rather than the rather narrow one of technical jargon, which those who DO understand such would not need in detail. I know this balance to be an old discussion, but I DO suggest you make room for (wider) concerns, starting with a change of the index. A central heading just called CONCERNS containing the present concerns, OR a referral from such to separate topic, eg "5G concerns". I mean: 5G implies a changed Earth in the way we communicate and utilise data, and concerns are 4 measly lines, of which 2 are mine! Krabat —Preceding undatedcomment added 10:39, 23 April 2019 (UTC)

On the assumption that, at some state, a section on problems/concerns/criticisms/controversy will be added to this entry (though maybe I'm being too optimistic) here is another article from a mainstream publication, this time the respected magazine the New Yorker. It adds the issues of surveillance/political security to the issues already mentioned (i.e. danger to trees, aesthetic and environmental concerns, health issues, etc.): Be-nice:-) (talk) 12:34, 30 April 2019 (UTC)

Oops...I just noticed that there is in fact the basis for a surveillance section in the article. The above New Yorker article might be a useful source for expansion of that.Be-nice:-) (talk) 12:56, 30 April 2019 (UTC)

I came across this recent article in The Lancet which may be a useful link for the issue of health effects. It specifically mentions 5G: (talk) 12:08, 15 May 2019 (UTC)

Useful for an update (20160530)?[edit]

(source: Huawei validates key 5G technologies... Dylan Bushell-Embling... May 30, 2016...

Huawei has announced it has completed the first stage of key 5G technology tests as part of a series of 5G field trials organized by the IMT-2020 5G Promotion Group.

The vendor completed outdoor macro-cell tests in Chengdu, China consisting of a number of key 5G enabling technologies and an integrated 5G air interface.

As part of the trial, Huawei evaluated three foundational technologies - filtered orthogonal frequency division multiplexing (F-OFDM), sparse code multiple access (SCMA) and polar code - the air interface technology.

Results show that F-OFDM was able to improve system throughput by 10%, SCMA was able to increase uplink connections by 300% and downlink system throughput by up to 80%, and polar code provided coding gain of between 0.5dB and 2dB compared to the code used in LTE systems.

Huawei said results of the test demonstrate that the new 5G air interface technology can improve spectral efficiency and meet the ITU-R's diverse service requirements for the standard.

The IMT-2020 5G Promotion Group was launched by the China Academy of Information and Communication Technology to encourage joint efforts to promote 5G field trials and evaluations among the global mobile industry.

Earlier this year the group announced a three-phase 5G trial plan spanning from 2016 to 2018.

Current status?[edit]

In 2018 Verizon plans to roll out 5G FWA  <---   FWA???  definition???

"Is 5G Over-Hyped?

" . . . [speed] depends on what frequency bands are used — 6GHz, 28GHz, 27 GHZ. The higher the frequency the more fibre you need closer to the user in order to deliver those higher speeds. Currently less than 50% of mobile towers are connected to fibre, and the rollout of fibre can't keep up with the rapid deployment of mobile broadband. 5G means more mobile towers so it is unlikely that all of these towers will be linked to fibre in the near future. [etc.]"

-- Jo3sampl (talk) 20:17, 31 May 2016 (UTC)

Current status is negotiation and planning. Results are a matter of what year. A few users may expect all these wonders to become an everyday experience the same year that the new standard makes its splashy first appearance, or the following year. Most of those will be disappointed. Deployment will take years. Years after first 4G, it isn't everywhere yet, and won't be when 5G starts. Jim.henderson (talk) 13:21, 3 June 2016 (UTC)

5g demo from Sprint[edit]érica-centenario.htm

"Sprint Shows Off 5G With Blazing Fast Speeds At Copa América Centenary”


“The demonstration employed beam stitching, which works by tracking the device in use, selecting the best antenna and sending the signal to a set location.”

"An FCC spectrum auction last month also showed strong implication, further paving the way toward fast and reliable 5G networks. AT&T, Verizon and T-Mobile will likely spend billions on 600 MHz spectrum, but Sprint is not interested. Sprint already has plenty of 2.5 GHz spectrum – more than any of its rivals – and when it comes to 5G, it's considered low-frequency spectrum. This means that it should be better at penetrating walls and buildings and traveling farther, thus translating to wider coverage.”

Also — up to 2Gbps during demo; used 73 GHz millimeter wavelength spectrum for demo.

As of June 2016[edit]

"5G remains the driver for new product development . . .

"However there is no standard for 5G deployments and no one knows what the final specs will look like. Consensus suggests that 5G will utilize Massive MIMO (multiple input, multiple output) antennas — perhaps dozens (or hundreds) per basestation — each with their own spectrum and modulation scheme. Thus, every RF supplier — no matter how narrow their focus — will claim a slot among the MIMO attachments. "If you can’t find channel bandwidth on the upper spectrum of the millimeter wave bands, consider carrier aggregation at lower frequencies. WiFi and LTE, for example, will likely “co-exist” on the same tower.

"Orthogonal frequency division multiplexing (OFDM) is one way of putting additional data channels on a given frequency range . . . . OFDM is a modulation technique, which can utilize multiple carriers, within an allocated bandwidth and could enable a 10 Gbits/second data. Each carrier utilize one of the several available digital modulation techniques such as binary phase shift keying (BPSK) or quadrature phase shift keying (QPSK), or quadrature amplitude modulation (QAM) with 256 or 1024 constellation points. (802.11ac, for example, uses a 256-point QAM for every data bit transmitted.)" accessed 20160707

Wavelength controversy?[edit]

retrieved 20160920

'Stéphane Téral, an analyst at IHS Markit, recently weighed in by criticizing the use of “5G” to describe sub-6 gigahertz developments in a research note.'

'Many [carriers] have set their sights on much shorter millimeter waves that fall between 30 and 300 GHz. There are plenty of frequencies available in the millimeter-wave range, because they’ve been used only for specialized applications such as remote sensing and military radar. But waves at these frequencies can’t travel as far or make it through as many obstacles . . .'

'[5G analyst Anshel] Sag thinks it’s a mistake to rule out anything other than millimeter waves as true 5G. He says 5G New Radio, a wireless standard defined by the global wireless standards group 3GPP, should count as 5G no matter which frequencies it handles.'

Standards for 5G still not coming until 2018[edit]

5G definition and Chinese company ZTE[edit]

'Asked about plans in South Korea to launch some form of 5G in 2018, Alex Wang said 5G can be a marketing name, with different operators defining 5G in different ways: “We follow closely the 3GPP standard and believe it’s a more neutral and technically sound definition.”

' “We consider Chinese and Japanese operators as following the more strict 3GPP-based definition, with 5G launches around 2020. Any launch earlier than that is up to the indivdual operator to define, but we don’t think that’s standard compliant 5G.”

'With phase two of China’s national 5G implementation already underway, ZTE is working closely with China Mobile on different aspects of the operator’s 5G trials, including radio and core networks, and the interworking of network features.'

Complete update and rewrite[edit]

The article was mostly unchanged since 2016 in a very fast moving field. Many references were to 2011 and 2013. Rewrote entire article, removing many out of date datapoints, obvious pr, and errors. Actual deployments replaced trials. Shortened some sections with extraneous material. (I'm a tech reporter covering this field and have written over 50 articles. That doesn't mean I got everything right. Improvements welcome.) I made a major change/update to paragraph 2, which said 5G was millimeter wave only. Since then, Massive MIMO and low band 5G have been accepted by most as part of 5G. There's no formal definition so I included all 3 saying "some consider." At the MWC this week, it appeared 3/4ths of the announced 5G plans were low band, which had been left out. Is that the right solution? The article would be improved with more technical information and more links to recently published books/articles.

I agree. It needs a comparison table of: 0G, 1G, 2G, 3G, 4G and 5G. — Preceding unsigned comment added by (talk) 21:43, 29 April 2018 (UTC)

Daveburstein (talk) 14:15, 6 June 2018 (UTC) I corrected major confusion in the article. After more than a year of dispute, the term 5G has generally been accepted to include any system utilizing 3GPP New Radio. Hundreds of regulator statements, news reports, and much of this article use the "new definition." (Which I think is highly misleading but has become common usage.) That means much of "5G" does not meet the ITU IMT-2020 standard of 20 gigabits, which the article was claiming. It's 70% to 90% slower. Made several changes to make clear what was IMT-2020 (20 gigabits, mostly microwave) and which was not (everything below 6 GHz.) If anyone sees it differently, please email me and I will send more data to you. Daveburstein (talk) 14:24, 6 June 2018 (UTC) Removed "technology" section except New Radio. All listed were developed for 4G before 5G. Further changes necessary in a fast-moving field.

Thank you for your time and efforts, 5G article is much more valuable information than the previous version. Goodtiming8871 (talk) 21:31, 8 June 2018 (UTC)

Real-world tests[edit]

As 5G is approaching to us, I think it would be beneficial for us to know the practical speed (not written in the book) and bandwidth for average users. I updated some simulation results and comparison table to 3G and 4G. Please update further actual test results and references to this article when it's possible. Goodtiming8871 (talk) 21:29, 8 June 2018 (UTC)


Hi - I see you have edits that are clearly very important to you. They contain a number of technical inaccuracies. I don't personally see how you will get them to a state where they are accurate. Not quite sure what the Wikipedia rules are for things like this, but I'm sure everyone's preference is that people not make earnest but inaccurate contributions. Hawerchuk (talk) 05:41, 10 June 2018 (UTC)


Hi, as you are well aware of it, the 3G and 4G mobile are now standard for the world; the 5G mobile could affect most of the people in the world shortly within a few years(examples, the year 2020-2021). It would be crucial not for few people but the significant population. As the standard of 5G is not yet fixed, and still one of the primary agenda, [1] it would be impossible to write the concrete result of the capabilities of 5G technology. However, it would be possible to predict the practical outcomes based on the real-world test by the 5G professionals. Please update the article or provide the feedback on talk page based on further references. We would be able to achieve better understanding what could be the realistic 5G standard. Goodtiming8871 (talk) 22:53, 10 June 2018 (UTC)

I don't quite know what you're saying. But let me give you an example of what I mean from your text:

"The technology of small cell was already utilised to 3G and 4G mobile radio technology. However, small cell in 5G is now the crucial part of achieving several gigabits per second Bandwidth and low latency. It is now indispensable to use the small cell when you deploy high bandwidth 5G fixed wireless service because of characteries of the new 5G mobile band which is Millimeter wave frequencies(24-86GHz)."

-> "several gigabits per second Bandwidth" -> "gigabits per second" is throughput; Bandwidth in the context of 5G is measured in MHz -> "indispensable...when you deploy high bandwidth 5G fixed wireless service" -> 5G needs small cells to enable much more than mmWave fixed wireless

"It is one of the primary technology for 5G networks; it will transmit data through targeted beams and advanced signal processing that could speed up data rates and boost bandwidth using massive MIMO antennas, it is a technique that sends the radio signals intensively to the places where many data are actually needed."

-> "it will transmit data...that could...boost bandwidth" -> again, there's no notion of beamforming increasing bandwidth, you're mixing it up with throughput -> "it is a technique that sends the radio signals intensively to the places where...actually needed" -> this is not a technically-accurate description of beamforming -> "it will transmit data through...advanced signal processing" -> this is not an action that the transmission of data can take

I don't really see the point of re-inserting erroneous text like this. Hawerchuk (talk) 05:46, 11 June 2018 (UTC)

Concerning (Hawerchuk)'s comment about 5G technology,

I believe that it's highly beneficial for us to articulate the definition of the 5G technology area. Let me add the reference of the examples that I see what is correct:
1) (Hawerchuk) Bandwidth in the context of 5G is measured in MHz -> (Goodtiming88781) the function of Millimeter-wave bands: it can deliver greater capacity of the data comparing the Centimeter waves, but the bandwidth should not be measured with MHz but "bits per second (bps)".

  • "MHz" : it is measurement unit for the frequencies not for Bandwidth. [2]

2) (Hawerchuk) again, there's no notion of beamforming increasing bandwidth, you're mixing it up with throughput (Goodtiming88781), The reference on exaplined clearly that Beamforming(= targeted beams) boost bandwidth, and as per the reference(1) above network throughput is directly linked with bandwidth on the network. [3]
3) (Hawerchuk) this is not a technically-accurate description of beamforming (Goodtiming88781), Please see the IEEE reference 2)above and the description below, it also accurately described the meaning of beamforming. "For millimeter waves, beamforming can help by focusing a signal in a concentrated beam that points only in the direction of a user, rather than broadcasting in many directions at once." Goodtiming8871 (talk) 02:20, 12 June 2018 (UTC)


The text in the beamforming section was copied verbatim from the reference cited in that section, so I removed it. Hawerchuk (talk) 06:44, 12 June 2018 (UTC) I don't think the summary of the long contents of reference: it is not the copy of the material. I will recover it with additional clarification. If you think it is an exact copy of the reference, please paste the evidence of contents here. Goodtiming8871 (talk) 06:09, 18 June 2018 (UTC)

Tagged article[edit]

1) "The proposed 5G applications": the same information is in the next section. If someone is trying to say something different, clarification is required.

2) "Small Cell": Clarification required. I think I understand what the text is trying to say, but it's not correct (small cell is key to 5G, not just for mmWave)

3) "Network Bandwidth and Deployments": There are numerous technical inaccuracies, there's irrelevant info, and some of this section contradicts some of the other sections tagged above for clarification.

Hawerchuk (talk) 02:16, 16 June 2018 (UTC)
Please note that mmWave must use a small cell, however a small cell is not an essential part of centimetre wave, and a centimetre wave is also used in a 4G network. if you think that a small cell is an essential part of the centimetre wave in 5G, Please place the proper references on here if possible.

Article about dangers of 5G[edit]

I looked this article up having come across some stuff on the Internet warning about the dangers of 5G. I found the article completely incomprehensible. (I don't have a physics background, though I know a fair bit about the philosophy of science and I've read a lot of popular science.) There are many technical terms even in the lead that don't have relevant links. I accept that with such a technical subject some level of incomprehensibility for the layperson may be inevitable. However, I do think there could be a paragraph or two, if only in the introduction, setting out in plain language what the article is about. I also couldn't find anything on the supposed dangers of 5G, which ought to be included or at least linked to. If anyone who knows the subject well enough feels up to doing this, that would be great. Thanks :-)Be-nice:-) (talk) 22:58, 19 June 2018 (UTC)

Regarding EMI and human health, I realised that it requires the specific rule to WP:MEDRS (medical related term), we would need to discuss more references for EMI and Human health. Goodtiming8871 (talk) 05:13, 25 June 2018 (UTC)

Hi, me again :-) I understand there is some issue re the status of whatever negative information on 5G is out there. However, I'm more interested in actually getting the info than in modifying the article in one direction or another. I can make my own decision re the trustworthiness, or otherwise, of the info. So if someone could kindly direct me to the pre-deletion version so I can follow up the sources without stepping on anyone's toes, that would be great. I presume its in the archive somewhere, so it should be just a question of finding it. Thanks!Be-nice:-) (talk) 00:05, 17 September 2018 (UTC)

What might be worth mentioning in that the International Society of Doctors for the Environment has called for standstill of the roll out in the respect of the precautionary principle.[1] That report has about 50 references in the scientific literature to biological effects and 17 of those are specific to MMW.

Furthermore, specific preliminary evidence showed the exposure to frequencies over 30GHz could alter gene expression(16,36,37,38,39), increase the temperature of the skin(40), stimulate cell proliferation(41,42,43), alter the functions of cell membrane (44,45)and neuro-muscular systems (46,47,48,49,50,51,52),

and are able to modulate the synthesis of proteins involved in inflammatory and immunologic processes (53), with possible systemic effects.

There is also press coverage of this although is the Daily Mail[2] and local news in Cornwall[3] which is going to be one of the first rollout areas.

While I'm skeptical of the health benefits I think we should at least document that some major orginisations have protested. --Salix alba (talk): 13:19, 24 October 2018 (UTC)

Network bandwidth and deployments[edit]

The references for this section do not meet WP:RS. I have removed the section and invite editors to discuss changes at talk before re-adding them to the article.

--Hawerchuk (talk) 20:30, 22 June 2018 (UTC)

As I mentioned, this section does not meet WP:RS. Some examples:

a) "In 2016, Federal Communications Commission(FCC) approves the usage of the new Extremely high frequency (EHF) frequencies range (in another word; Millimeter wave) in next-gen 5G technologies. As the EHF frequencies range is finally accessible on the mobile network, there is an opportunity of the new bandwidth with the requirement of small cell infrastructure because of propagation characteristics of shortwave(example: Millimeter wave). [59]"
While reference [59] does indeed talk about mmWave spectrum allocations by the FCC, it's not clear what is meant by "opportunity of the new bandwidth", nor does the reference to shortwave (up to 2 MHz) make any sense in the context of mmWave (up to 86 *GHz*). Also, nobody in this industry refers to these bands as EHF - if someone wants to use that term, they should find references from relevant sources.
b) "IMT-2020 systems demonstrated to June 2018 used millimetre wave. Systems using bands below 6 GHz have been estimated to reach 4 gigabits per second via 64 QAM modulation, not the 20 gigabits of IMT2020. However, it is the peak network bandwidth simulation with a 64 QAM modulation between 28 and 39 GHz(millimetre wave) that the approximated value was calculated at. [60]"
First, it's not true that demo systems used only mmWave; in the prior section of this article, there are a list of trials and launches in the US that include several sub-6 GHz launches. Second, nobody is claiming 4Gbps for bands below 6 GHz; in fact, reference [60] talks about 4Gbps for mmWave. Third, the mention of 64-QAM misunderstands the article - the interviewee is talking about how 64-QAM is used at mmWave frequencies vs 256-QAM for sub-6 GHz, and that it's a hindrance to getting high throughput. Fourth, the article makes no mention of simulations - it's entirely focused around real-world tests.
c) "The real-world 5G network test results from Qualcomm's the Frankfurt simulation are as follows. In a mobile 5G network, 90% of users could use an average speed of 100 Mbps. In the San Francisco simulation, 5G users were able to use 1.4 Gbps of speed at 5G mmWave coverage.[61] Ericsson and NTT DoCoMo also tested the practical 5G network speed.[62]"
For reference [61], the editor is taking a simulation and calling it "real-world 5G network test results"; if the editor wanted to write a section on the potential capacity of 5G networks, this would be one point they could make, but here it ends up just being PR for the company trying to sell the technology. The mention of reference [62] is completely superfluous - it doesn't matter than Ericsson and NTT DoCoMo tested a network (there is a section above on vendors and network launches) - what did they find?
d) "When the mobile industry wants to deploy the 5G infrastructure, the Millimeter waves of 5G frequencies (e.g, 15-86 GHz band)[63] should be considered, As it requires the 1 to 10 mm waves compared to the 3G or 4G frequencies [64](e.g: 850 MHz,1.8 GHz,2.1 GHz,2.3 GHz, and 2.6 GHz) which are tens of centimetres in length.[65]"
This is unclear. There is plenty of discussion about mmWave earlier in the article, not sure why it is mentioned here again. Ref [64] and [65] do not say what the words preceding them say.
e) "The 5G network cellular tower should be designed for much smaller cells, compared to the current 3G/4G base station tower. In the case of the 3G/4G network cellular tower, it is technically possible to cover up to 50km-150km by adjusting the output power [66] however the fixed wireless 5G cell stations should ideally be designed to cover distances of 250-300 m due to technical limitations.[67]"
This depends on whether we are talking about sub-6 GHz 5G (the bulk of deployments) or mmWave 5G. There is no reason to design for smaller cells if you are using the same bands as 3G/4G, and there are plenty of references the editor could have found that talk about co-locating 4G and 5G towers for this reason. Ref [67] does not refer to 200-300m cell size, but it does refer to some experiments Samsung is doing - this is not guidance for network deployments as a whole.
Every sentence in this section has similar problems - technical inaccuracies, conflating sub-6 GHz and mmWave, misinterpretation of references, insertion of references that don't say what's claimed in the section. The editor is clearly attached to the section but needs to re-write for relevance and clarity.
--Hawerchuk (talk) 21:49, 22 June 2018 (UTC)
Hawerchuk, I agree text should be supported by any reference given and written clearly. However, this section does not appear to be about health effects, so WP:RS, and not WP:MEDRS, should suffice. --papageno (talk) 01:10, 23 June 2018 (UTC)
My bad. Changed to RS.
--Hawerchuk (talk) 03:38, 23 June 2018 (UTC)
Kleuske As papageno notes, I should have deleted the text due to WP:RS, not WP:MEDRS. That was my bad. I changed to WP:RS. My edit should not have been reverted. If you believe the text meets WP:RS, please discuss it on the talk page.
--Hawerchuk (talk) 19:20, 23 June 2018 (UTC)
@Hawerchuk: At the face of it, sourced content was deleted. You claim the sources are not WP:RS, so I'd like to know what sources you object to and what your objections are. Kleuske (talk) 19:37, 23 June 2018 (UTC)
@Kleuske: I outlined issues the first five sentences above; there are issues with every other sentence, but it's incumbent on the editor who added them to fix them. Certainly item (c) is WP:RS. I don't think the expectation is that I explain the flaw in each sentence and *also* classify every single flawed sentence based on its specific flaw. If you can tell me the correct classification for "You can't just write a bunch of random words and then add a reference that does not match what you wrote", I will use that instead.
--Hawerchuk (talk) 22:24, 23 June 2018 (UTC)

───────────────However the matter should be classified properly, I believe Hawerchuk has identified legitimate problems with the proposed text, problems that should be cleared up before it is added to the article. Perhaps User:Goodtiming8871 would like to create a sandbox section at his/her talk page where interested editors could help to improve and refine the text first, before submitting it here for approval for inclusion? It would be great to harness the interest that User Goodtiming8871 clearly has for the subject. Face-smile.svg --papageno (talk) 21:40, 24 June 2018 (UTC)

───────: Hi Hawerchuk, regarding the technical descriptions, I believe that the content just need to be refined instead of removal as per the example reasons below- part (a)

Hawerchuk' comment; a) "In 2016, Federal Communications Commission(FCC) approves the usage of the new Extremely high frequency (EHF) frequencies range (in another word; Millimeter wave) in next-gen 5G technologies. As the EHF frequencies range is finally accessible on the mobile network, there is an opportunity of the new bandwidth with the requirement of small cell infrastructure because of propagation characteristics of shortwave(example: Millimeter wave). [59]" While reference [59] does indeed talk about mmWave spectrum allocations by the FCC, it's not clear what is meant by "opportunity of the new bandwidth", nor does the reference to shortwave (up to 2 MHz) make any sense in the context of mmWave (up to 86 *GHz*). Also, nobody in this industry refers to these bands as EHF - if someone wants to use that term, they should find references from relevant sources.

  • The issues of points from User:Hawerchuk
regarding reference [59][1]

1) [59] does specify mmWave spectrum allocations by the FCC, it is clear that "opportunity of the new bandwidth": example 20 Gbps bandwidth by mmWave
2) Professional of mobile industry refers to these band ( 30GHz- 86 GHz) are EHF; it is also known as mmWave. Please see EHF
3) EHF = millimetre wave;
"Hawerchuk" believes that if someone wants to use that term, they should find references from relevant sources --> (3) above, It is a just fundamental technical term, I don't believe it is probable for unpaid Wikipedia editor could add 10 references to every single line in the Wikipedia article. I believe that more than about 99.999% Professional in the mobile industry would understand that millimetre wave is the another terminology of EHF. Goodtiming8871 (talk) 05:09, 25 June 2018 (UTC)


"opportunity of the new bandwidth" -> As I noted earlier, you are using the term "bandwidth" incorrectly. I initially thought you meant that the FCC was opening up new "spectrum" (which you referred to as "bandwidth".) But with your statement in the talk section, someone might guess that you mean "throughput" (the error I was pointing out before.) I would suggest you take papageno up on the sandbox idea. You'll be able to get feedback to help clarify your technical content and the text itself.

Hawerchuk (talk) 06:15, 25 June 2018 (UTC)

As for EHF, the Wikipedia entry immediately switches to mmWave, which is the industry terminology. If you look at the corporate websites for Qualcomm, Intel, Ericsson and Nokia, you will not find one web page related to 5G that uses the term EHF. I don't see how you can claim it is a fundamental technical term if the bulk of the patent holders in the field don't use it at all.

Hawerchuk (talk) 06:15, 25 June 2018 (UTC)

───────: EHF can be redirected from MmWave, it means that it is precisely the same meaning: just a fundamental technical term. It will be an unreasonable claim that if someone says MmWave is a different meaning of Extremely high frequency because the corporate websites (example: Qualcomm) did not use the term of "Extremely high frequency" on their website. Please place a reliable reference in this place if you believe EHF is different terminology to MmWave. From my understanding, MmWave would be a popular terminology in the mobile industry, but we can not say EHF does not match with MmWave. Goodtiming8871 (talk) 02:53, 26 June 2018 (UTC)

───────: 230 results for "mmWave"; 2 results for "EHF" 258 results for "mmWave"; 0 results for "EHF" as used in this context (2 results for a different meaning) 130 results for "mmWave"; 0 results for "EHF" 153 results for "mmWave"; 0 results for "EHF" as used in this context (2 results for a different meaning)

Not sure what more you want. If they were equivalent terms, people would use them equivalently.

Hawerchuk (talk) 14:39, 26 June 2018 (UTC)

───────: I don't believe EHF is different terminology to MmWave regarding your examples above. that is just example of "popular usage" of terminology. Would you please be able to write a specific definition associated with the reference concerning: your claim: "EHF is different terminology to MmWave" otherwise please let other professional write their opinion.

IMT-2020 & 3PPP[edit]

Daveburstein (talk) 19:08, 20 June 2018 (UTC) Dave Burstein Major change: Pointed out IMT-2020 & 3PPP have different definitions. IMT-2020 goes to 20 Gbps, 3GPP to 2 or 4. Removed 200-300 meter cell size because Verizon is getting more. Many small updates and language fixes. Hypesters are implying that "5G" is 20 gigabits in deployments at less than 6 GHz. That's just an error. 20 gigabits is possible at millimeter frequencies like 28 GHz. That's the IMT standard. Nothing more than 4 gigabits has been demonstrated below 6 GHz frequencies, which are included in the 3GPP definition. Article confused them. Shortened stuff, took out unsourced claims that were dubious, etc. More work needed.

I think the intro to the article is confusing now. Do you want to re-write it? Hawerchuk (talk) 05:23, 21 June 2018 (UTC)

As you know, 5G-standardisation is on it's way [1] so we are able to see the current version of 5G-standardisation on the news and Wikipedia. I believe that we need to wait and see the final version later.

There is so much confusion in the article. 3GPP doesn't define standards, it develops specifications: That Verge reference at the industry standards group 3GPP has included any system using NR (New Radio) software does not support the claim.

the term was defined by the ITU IMT-2020 standard, which required a theoretical peak download capacity of 20 gigabits required for who/what? For candidate radio interfaces like NR. There is no 5G requirements for networks. There is only requirements for radio interfaces. See ITU document: : These requirements are not intended to restrict the full range of capabilities or performance that candidate RITs/SRITs for IMT-2020 might achieve, nor are they intended to describe how the RITs/SRITs might perform in actual deployments under operating conditions that could be different from those presented in other ITU-R Recommendations and Reports on IMT-2020.

It is actually ITU that defines a system to be 5G if it just uses a 5G radio interface like NR: As defined in Resolution ITU-R 56-2, International Mobile Telecommunications-2020 (IMT-2020) systems are mobile systems that include new radio interface(s) which support the new capabilities of systems beyond IMT-2000 and IMT-Advanced.

Clarifying definitions and speed estimates[edit]

Daveburstein (talk) 03:23, 25 June 2018 (UTC) Thanks Hawerchuk and others for improving this page. There is enormous confusion about the definition of "5G," which remains under dispute amid changes. Originally, "5G" was defined as 20 Gbps downloads, which in practice meant millimetre wave only. Those building and deploying in lower bands, from 600 MHz to 6 GHz, wanted to call their equipment 5G and persuaded the important 3GPP standards committee to include in "5G" what more closely resembled 4G than millimetre wave. (It's really 4G with a software tweak, New Radio, and only slightly faster. Opinion) Almost all the companies are delighted to apply the much-hyped term "5G" to their slower and less expensive mid-band deployments. That seems to be becoming generally accepted, including in policy work at the EU & FCC. That means some 5G will actually be slower than some 4G, which has some features - including LAA - that have not yet been implemented in 5G. There's no standard of what's right or wrong here, but the changes have led to very frequent errors. The result is that many ordinarily reliable sources get this wrong. If low & band are included in 5G, there are only modest performance improvements. (I preferred the older definition, but common usage seems now to accept the inclusion of low and mid-band.) Many assume that "5G" is much faster and has much lower latency. That's not true except for millimetre wave 5G, which will be a minority of deployments for the next five years. (Unproven but likely true.) I've reported broadband since 1999 and am working on a book, Gigabit Wireless. My sources include dozens of authorities in the field. That doesn't mean I will be right about everything, of course. But if you think my changes are in error, please email me and I'll be happy to point you to primary sources. Dave Burstein

Hi Daveburstein. Thanks for updating, appreciate all of the edits. 5G is so nebulous, I think it may take us a few more iterations to get things clean. e.g. "Initially, the term was defined by the ITU IMT-2020 standard, which required a theoretical peak download capacity of 20 gigabits." -> This is for eMBB, but I don't think ITU required 20 Gbps for URLLC and MMTC.

Hawerchuk (talk) 05:33, 25 June 2018 (UTC)

Can we have the lead section drafted in such a way that an uninitiated reader could make out what 5G is? Lengthy discussion on wawelengths, chipsets, competing standards does not help. Look at 3G for an example of good lead section. — kashmīrī TALK 08:36, 25 June 2018 (UTC)

Daveburstein (talk) 22:00, 25 June 2018 (UTC) Kashmiri and Hawerchuk I made some changes as you suggested. Your comments are sensible but unfortunately the problem is that the world doesn't agree on the definition of 5G. Moved down and rewrote the section on predicted speeds. I added three more citations. The Qualcomm model is consistent with many other datapoints including Verizon's data on millimetre wave and is well documented. I put at the top this is uncertain until we have more results from the field. With the caveat, I believe it right to leave it in because it provides a well-resourced, less technical way to understand what is coming.

This is more than semantics; the article in earlier drafts had major errors due to the confusion. Most "5G" is not much better. (Millimetre wave is much faster but based on telco announcements will only be a minor part.)

Under the newer definition, much - probably the strong majority for five years - of "5G" will not be much faster than "4G" with the same number of antennas and spectrum. That has important implications for policy, where lobbyists are demanding major changes to "incent 5G."

Here's what I came up with. Improvements welcome. Dave

I like kashmīrī's suggestion. We may as well just copy the text from 3G and use it to describe how 5G is an upgrade on 4G.

Hawerchuk (talk) 22:48, 25 June 2018 (UTC)

The combination of the two frequencies below; that is 5G network as per the proposed 5G standard.
Frequency range 1 (< 6 GHz) - for coverage
Frequency range 2 (24–86 GHz) for speed by Small cell
I believe that we can say the maximum speed of 5G via millimetre waves only which is the much higher performance of the current 4G. Goodtiming8871 (talk) 03:10, 26 June 2018 (UTC)

Summary of Small cell and Beamforming[edit]

The summary of the two parts was removed continuously by the user: Hawerchuk, but he did not leave any proper reason or reference. ( Hawerchuk edits appear to be disruptive as the contents could be clarified or improved by other professional users in the future.)
I would like to get consensus with other users about the requirement of the summary of the two topics below instead of linking to several pages of information which might be too much data to read for general users.

Small cell Main article: Small cell
The technology of small cell was already utilised to 3G and 4G mobile radio technology. However, small cell in 5G is now the crucial part of achieving several gigabits per second Bandwidth and low latency. It is now indispensable to use the small cell when you deploy high bandwidth 5G fixed wireless service because of characteries of the new 5G mobile band which is Millimeter wave frequencies(24-86GHz). The ITU released the new mobile Radio frequencies on the World Radio-communications Conference which is the range of Extremely high frequency. Technically, Millimeter-wave spectrum(mmWave) has the functionality that "mmWave (Extremely high frequency)’ could be able to handle breakneck 5G speeds." [1]

Beamforming Main article: Beamforming
It is one of the primary technologies for 5G networks; it will transmit data through targeted beams and advanced signal processing that could speed up data rates and boost bandwidth using massive MIMO antennas. It is a technique that sends the radio signals intensively to the places where lots of data is actually needed. [2]


Goodtiming8871 (talk) 04:58, 26 June 2018 (UTC)

Goodtiming8871, I have given you feedback on how to improve almost every sentence you've written; that is hardly "disruptive". However, since you're asking, I will provide you with feedback on these sections as well:

"However, small cell in 5G is now the crucial part of achieving several gigabits per second Bandwidth and low latency. It is now indispensable to use the small cell when you deploy high bandwidth 5G fixed wireless service because of characteries of the new 5G mobile band which is Millimeter wave frequencies(24-86GHz)."

1) As I already explained above, "Bandwidth" is not the correct term for what you are describing. The term is Throughput. 2) IMT-2020 eMBB targets' multi-Gbps throughput but does not target low latency. Low-latency (but not high throughput) is proposed for IoT and self-driving cars. 3) The second sentence says the same thing as the first ("crucial" vs "indispensable"). 4) You make reference to "characteristics" of "the new 5G mobile band" - what are they? Why do they make small cells indispensable? 5) You mention "fixed wireless" and "mobile band", which will confuse people - fixed and mobile are antonyms.

"Technically, Millimeter-wave spectrum(mmWave) has the functionality that "mmWave (Extremely high frequency)’ could be able to handle breakneck 5G speeds.""

1) This doesn't make sense. Why does mmWave have any particular functionality that enables high speeds? You get speed by allocating more spectrum, not by using any specific chunk of spectrum. 2) You are using EHF here again, which as I noted, is not a term used in this industry. 3) We are talking about highly quantitative specifications - it does not make sense to use a nebulous term like "breakneck".

"It is one of the primary technologies for 5G networks; it will transmit data through targeted beams and advanced signal processing that could speed up data rates and boost bandwidth using massive MIMO antennas."

1) Data can't be transmitted through "advanced signal processing". 2) Beamforming cannot boost "bandwidth". As I noted several times, you are conflating Throughput with "bandwidth". 3) There is no dependency on massive MIMO. Beamforming delivers value independently.

"It is a technique that sends the radio signals intensively to the places where lots of data is actually needed."

This is not a clear description of beamforming. See beamforming for a better (but not great) description of the technology.

Hawerchuk (talk) 14:32, 26 June 2018 (UTC)

Hi Hawerchuk, Please restrain to write your own idea without proper reference and let other professionals describe their opinion as the consensus of talk in this section might require about several people's views with reference not a discussion between two people. Goodtiming8871 (talk) 23:37, 27 June 2018 (UTC)

You have misinterpreted a lot of details in the articles you cite, and in good faith, I have explained these details to you. I am addressing your references; there are no additional references to provide. I don't think your response is warranted.

Hawerchuk (talk) 18:39, 28 June 2018 (UTC)

───────: Although you said a lot of details were misinterpreted, it could also be your misunderstanding about several technologies. As one example of technologies: bandwidth, let me know whether IEEE Spectrum Staff: Amy Nordrum, Kristen Clark accept your advice whether they made a crucial mistake of using the wrong terminology on their IEEE public press release. Goodtiming8871 (talk) 23:24, 28 June 2018 (UTC)

───────: I explained this above. One person wrote the article, somebody else wrote the headline, and that person misused a word. Just because one person made a mistake, it doesn't mean we propagate it into this article. Please, let's move on. Hawerchuk (talk) 16:46, 29 June 2018 (UTC)

Definition of Bandwidth[edit]

Ok, I think I see the issue now:

1. For the IEEE article[1], the person who wrote the title is not the same person who wrote the article. This is not uncommon. Unfortunately, the person who wrote the title made a mistake in the way they used the term 'bandwidth'. Note that 'bandwidth' does not appear in the article itself.

2. For the other page[2], that is a different industry, which uses a different definition of bandwidth. In cellular, bandwidth refers to the quantity of frequency allocated to the user; throughput refers to the data rate. In ethernet or optical transports, the frequency range is (essentially) unlimited, so 'bandwidth' is used in a different way without ambiguity.

Given that, hopefully you'll fix your contributions... Hawerchuk (talk) 06:38, 12 June 2018 (UTC)
Would you be able to place the reference of your idea? I was unable to see any reference to your understanding. Goodtiming8871 (talk) 05:53, 18 June 2018 (UTC)

I placed the previous topic about bandwidth that you consider that the author of IEEE confused the definition of bandwidth on a professional article from IEEE. Please write the reference if you believe that the expert author of this article does not understand what bandwidth is. If you are more knowledgeable than the IEEE Spectrum Staff: Amy Nordrum, Kristen Clark, Please advise them their confusion via email on the article. Goodtiming8871 (talk) 00:01, 28 June 2018 (UTC)

1) See Wiki entry for Mobile Broadband: [3]. Bandwidth = "wider channel frequency bandwidth in Hertz"; article distinctly notes "Speeds in Mbit/s"
2) See Wiki entry for Cellular Frequencies: [4]. "Each block is between 10 MHz and 30 MHz in bandwidth"
Cellular/mobile broadband industry uses 'bandwidth' to refer amount of spectrum. You can certainly find colloquial references to 'bandwidth' meaning speed, but those are sloppy, and that error should not be propagated here.

Hawerchuk (talk) 18:29, 28 June 2018 (UTC)

───────: Please find another advice explains the meaning of Mobile Bandwidth "An Expert Explains 3G, 4G, WiFi" [5] As I described your misunderstanding about bandwidth, Speeds in Mbit/s = it is data throughput in the mobile network, and it is also terminology: bandwidth. If you are confident that IEEE Spectrum Staff: Amy Nordrum, Kristen Clark is wrong with their understanding about mobile bandwidth, please advise them to fix their mistake in the public release below on IEEE. Goodtiming8871 (talk) 23:30, 28 June 2018 (UTC)

User Hawerchuk (talk) is correct. In wireless communications, bandwidth refers to the amount of frequency spectrum over which a signal is sent. It's even in the Wiktionary definition of bandwidth and the Wikipedia article on bandwidth. For the sake of clarity (or as User Hawerchuk has written, "lack of ambiguity"), we should use bandwidth only with that meaning, and throughput for the amount of data per unit time (see Wiktionary article on throughput and Wikipedia article on throughput). Let's move on from this.--papageno (talk) 00:25, 29 June 2018 (UTC)
Yes bandwidth denotes the width in frequency space used by a signal. For many modulation methods, the bit rate and bandwith are proportional with a proportionality constant near unity. You can trade signal/noise vs. bit rate over a small range. The result of this, is that bandwidth is commonly used to describe bit rate. Yes it is wrong, but probably a WP:COMMONNAME by now. Not quite as bad as broadband, which is supposed to mean bandwidth large compared to center frequency, but now has other meanings. Gah4 (talk) 06:11, 4 January 2019 (UTC)
The relationship between bandwidth (spectrum usage) and bit-rate also depends on the encoding system that is used, which should be taken to include any error-correction etc. And to be accurate, "bandwidth" refers to the spectrum usage of a single band; 5G evidently uses multiple bands simultaneously in a single connection. Bandwidth != bit-rate. MrDemeanour (talk) 10:38, 2 May 2019 (UTC)


5G cellphone’s location privacy broken before it’s even implemented[edit]

Hi all

I don't understand enough about the subject to integrate this information, but this seems important, could someone take a look?


John Cummings (talk) 11:09, 10 December 2018 (UTC)

John, to me it looks like another superclever theory to be able to break into a mobile conversation, again via a fake intermediate station (Imsi catcher), but not by identifying the mobile phone by its stable Imsi-Identity but by (guessing) dynamic sequence numbers. That’s certainly more difficult than with current standards, and if it really can be done remains to be prooved – I think. To go to all that effort just to find out where a mobile is is highly improbable, tedious and time consuming. Intellectual games! (“If you’ve lost your 5G better buy a new one” :–) – Fritz Jörn (talk) 09:01, 30 December 2018 (UTC)
From the article description, the possible problem mentioned by the article doesn't seems to be specific to 5G and is also applicable to other generations of mobile technology. So it should be mentioned in other article that cover the topic directly instead of this article that's only indirectly related to it because that technology is also used here.

Needs explanation understandable by general readers[edit]

This jargon-ridden, poorly organized, fragmented article will be practically incomprehensible to general readers who are not familiar with cellular technology. It desperately needs a plain language introduction. For those of you who are concerned about the myths, pseudoscience, and conspiracy theories growing up around 5G, I'd suggest that one reason non-technical people believe these myths is a lack of accessible explanations of the technology. A Wikipedia article that actually explains this new technology in an understandable, human-friendly way might help demystify it. --ChetvornoTALK 19:31, 23 January 2019 (UTC)

It would be easier to achieve what you proposed if most websites stop advertising 5G as if some sort of magic that would overturn the life of every human being on the planet and revolutionalize every single industry on earth, but that seems to be asking too much for any non-technical-oriented sites, and that's probably one of the reason why the article is mostly focusing on those deeply technical aspects. It would be nice if someone can introduce the subject in a better way, at the very least one can split all the more technical aspects into more technical sub-articles, but that seems to be out of my capabilities. C933103 (talk) 05:40, 25 January 2019 (UTC)
I absolutely agree with you about the tech websites; most of them get their income from the advertising and promotional budget of giant telecom firms and are captive cheerleaders for the industry. In particular, there seems to be little discussion of the elephant in the room: unequal access to this technology. Deployment seems to be aimed at cities. If left to the telecoms I don't see how it will ever be extended to rural areas, which already desperately need broadband service, so 5G will just exacerbate the "digital divide". --ChetvornoTALK 07:18, 25 January 2019 (UTC)
Added an overview section, written in what I hope is less technical language. --ChetvornoTALK 07:18, 25 January 2019 (UTC)
Wow. Someone has managed to remove from the overview I wrote the information ordinary readers would most want to know: 5G's capabilities and how they differ from previous cellular networks. Now the article is practically content-free for general readers. The jargon-laden introduction, in addition to omitting any kind of description of 5G, even manages to conceal the fact that it is a cellular technology: "5G is a commonly used term for certain advanced wireless systems." Talk about your WP:VAGUELEAD. Seriously, folks, if you had a non-technically-educated friend who wanted to know what 5G was, would you send them to this article? --ChetvornoTALK 01:45, 20 April 2019 (UTC)

Health effects[edit]

Scientists have concerns about the health effects from the potential widespread involuntary radiation exposure to the 5G cell towers, so I'd to request that be covered by the article.[4][5][6] Thanks. Praemonitus (talk) 17:29, 28 January 2019 (UTC)

No, because 2 sources of yours violate WP:NPOV and the other (Salon) goes against mainstream scientific opinion see WP:FRINGE, as resolved by numerous edits and reverts, the health effects of microwave radiation, if any (see edits reasoning) should be listed as a link to a separate article at the bottom of the page, not as mainstream opinion. - || RuleTheWiki || (talk) 11:49, 29 January 2019 (UTC)
Okay. Praemonitus (talk) 16:50, 29 January 2019 (UTC)
Since when exactly NPOV started to mean "mainstream point of view"? Are you confusing letters? -- A man without a country (talk) 16:07, 5 April 2019 (UTC)
Whether health concerns are well-founded, there is concern. User:Fred Bauder Talk 17:09, 6 April 2019 (UTC)
whether something goes against mainstream scientific opinion or not isn’t necessarily the deciding factor as to inclusion of alternative theories, such as, in this case, the growing analysis of the possibility of 5G having detrimental health effects. Alternative theoretical formulations have a valid case as to their inclusion (or not), as set out in WP:FRINGE and should - therefore - not be dismissed out of hand. Quoting from there: ‘’ “Alternative theoretical formulations from within the scientific community are not pseudoscience, but part of the scientific process. They should not be classified as pseudoscience but should still be put into context with respect to the mainstream perspective. Such theoretical formulations may fail to explain some aspect of reality, but, should they succeed in doing so, will usually be rapidly accepted.” ‘’ It may well become vitally important, literally, for the health concerns about 5G to be given space.

4G is correctly identified as 5G's "predecessor". But 6G isn't listed as 5G's successor. Donald Trump tweeted just recently that he wants 6G technology, so it's not like it doesn't exist or something.2604:2000:C682:2D00:2813:62EC:E222:A7F3 (talk) 04:46, 23 February 2019 (UTC)Christopher L. Simpson

Daveburstein (talk) 01:22, 12 April 2019 (UTC) The actual deployment of tens of thousands of cells by Verizon, SKT, Korea Telecom and LG+ has now given us data from the field from about a dozen independent testers, mostly journalists. I put the actual data and removed a great deal of previous speculation. I also removed a great deal of now outdated and less important matter. I removed the "should be reviewed by an expert." I'm sure I have some errors here but I have written dozens of articles about 5G and am working on a book. Thank you to anyone who fixes my mistakes. The comment above that the description at the beginning is unclear is sensible. Unfortunately, there are many different opinions about the proper description, including the note above about ITU vs 3GPP. I eliminated challenged definitions here and simply called it "advanced wireless." While many have further opinions, that's as far as consensus goes for now. That the city of Brussels has stopped 5G trials because of fears about radiation is an objective datapoint from a responsible entity. I don't think Brussels is right based on the evidence I've seen, but some reputable professionals including Harvard Professor Susan Crawford have doubts. It is not the job of Wikipedia to make a judgment when responsible parties hold conflicting views. The article, for now, has the Brussels decisions as well as links to the (more popular) opposite view. Improvements of course welcome. If anyone wants to review the evidence at lenght, I suggest they create a separate article and link to it. I've written about 200 pages on 5G so have a great deal of data. If anyone has questions about this Wikipedia article, my email is and much of my work is at Daveburstein (talk) 23:38, 14 April 2019 (UTC) replaced "supercedes" 4G with neutral term "follows." 4G will be important for many years 2025. Reworded claim that 3GPP is a definitive definition, pending agreement with ITU. (India has said they may block 3GPP at the ITU.) Wikipedia should stay neutral while the ITU (part of the U.N) and 3GPP are not in agreemnt. 3GPP is an industry association with essentially no direct or indirect public representation. Almost all countries, many companies, and civil society groups are represented in ITU. The ITU vs 3GPP is an active issue in Internet Governance, so I wanted to be precise.

Censorship health concerns over exponential increase in emf radiation checks over wikipedia neutrality[edit]

I urge editors to refrain any further suppression over the matter. And demand the section re-instalment. — Preceding unsigned comment added by (talk) 15:43, 18 April 2019 (UTC)

"Exponential", eh? You mean, the emf radiation increases at a rate proportional to - er - the amount of emf radiation? I can't make sense of that. Also, I suspect that the term "emf" is being used here by someone who doesn't actually know what it stands for. Otherwise I think they would have simply omitted it - "radiation" nearly always means electromagnetic radiation (which includes light and radiant heat). The kind of electromagnetic radiation you appear to be talking about is microwave radiation. There is no evidence that the amount of microwave radiation involved in mobile telephony is harmful, even if you are close to a cell tower. The acronym "EMF" stands for "electromagnetic field" or "electromotive force". In neither case does the phrase "emf radiation" make any sense. I'm sorry to whine about your misuse of technical terminology, but after all you are trying to refer to a technical subject.
"Censorship" is the active suppression of information by a government. That term is not applicable to private organizations such as WP.
"Demand": that's not how it works. It seems you are new around here. Take some time to read more articles, see how Talk pages work, and learn about the editing process. Have a look at reliable sources as a start. If you would like some help, don't hesitate to post a brief message to my user talk page - I'll pick it up within a day or so. MrDemeanour (talk) 10:58, 2 May 2019 (UTC)

Daveburstein (talk) 05:18, 8 May 2019 (UTC) I made a major change by deleting the section on Huawei security controversies. There is a (long) separate article on the subject. It is important, but applies to much more than 5G. It's certainly appropriate for someone to add here some references to 5G, Huawei and security, but please keep it brief and link to the main article. I also made numerous small changes reflecting new information as the first 300,000 users have been connected.

I note the discussion here about radiation dangers. I added two highly credible sources with citations. "In April, 2019, the city of Brussels in Belgium blocked a 5G trial because of radiation fears.[57] In Geneva, Switzerland, a planned upgrade to 5G was stopped for the same reason.[58]" I also added "Most authorities do not believe there is conclusive evidence of harm.[56]" I think this is a neutral, well-sourced section on an issue of concern. Improvements welcome, but I haven't seen solid information that adds much to the discussion.

It is not just Huawei that is in question. And it is specifically for 5G as you can see in the text.C933103 (talk) 10:29, 11 May 2019 (UTC)

Radiation fears[edit]

BoogaLouie The New York times recently made a report that seems like an op-ed that accuses RT America of spreading fake news about 5G radiation effects. I have found many news outlets that are not related to RT that are "spreading fears" of 5G like how it might cause cancer. According to DW around 250 scientists from around the world have signed a petition to slow down the roll out of 5G because they fear that 5G could cause cancer. I don't think that what RT America reported at that day was unusual in mainstream media. Most of American mainstream media have reported news about 5G radiation fears. According to a report from 2019/1/8 [ thus source] "Verizon will partner with The New York Times to create a 5G journalism lab, though the full details of how that program will work exactly are still unclear." so for me it does seem suspicious that the only news paper to report this was the New York times and therefore it looks biased towards Verizon. This section in my opinion needs to be updated with real scientific research sources not news outlets agenesis and even if we need to add something like that it should be summarised and not given too much details. So that's why I reverted your addition here --SharabSalam (talk) 15:30, 16 May 2019 (UTC)

SharabSalamThe significant issue with the RT report is that RT is an organ of the Russian government and does what the government -- under the leadership of Putin -- wants. What does Putin want? “We need to look forward. The challenge for the upcoming years is to organize universal access to high-speed internet, to start operation of the fifth-generation communication systems.”[ ] But that is for Russia, not for the US.--BoogaLouie (talk) 18:00, 16 May 2019 (UTC) -- (talk) 18:23, 16 May 2019 (UTC) --BoogaLouie (talk) 18:00, 16 May 2019 (UTC)
The problem with the text is that it is too much detailed and for that reason it become more about about RT America and Russia topic not 5G->radiation fears topic so because of that I felt that it should be summarised that if it has got significant attention from reliable sources. You can add this paragraph to RT America article it would be very suitable there but here with this amount of details it looks off-topic--SharabSalam (talk) 20:23, 16 May 2019 (UTC)
BoogaLouie an IP address editted your comment I reverted. Was that you? Please clarify--SharabSalam (talk) 21:12, 16 May 2019 (UTC)
Yes was me. Did not realize I was not logged in. --BoogaLouie (talk) 13:48, 17 May 2019 (UTC)

This is a notable topic for inclusion. SharabSalam's characterization of the NYT as an "op-ed" is an opinion that wouldn't hold up to community scrutiny or a RSN review. The NYT article is a top-shelf investigative report that is feature length. Unlike other news sources the NYT has a higher threshold of reliability and fact checking. The inclusion doesn't need to be so lengthy and detailed, I agree, but some mention of it needs to be here. -- GreenC 23:59, 18 May 2019 (UTC)

It seems that the NYT report has got some attention from other news outlets since the time we were talking here. I do feel that the story is worth inclusion now and I think that it should not be detailed. We should stay on the topic of the radiation fears. I think we can remove or squeeze some quotations such as these quotes. Putin: “The challenge for the upcoming years is to organize universal access to high-speed internet, to start operation of the fifth-generation communication systems,” and quoted US-based analysts worrying that “Russia doesn’t have a good 5G play, so it tries to undermine and discredit ours” (Ryan Fox of New Knowledge) and that the Russian government “would really enjoy getting democratic governments tied up in fights over 5G’s environmental and health hazards,” these informations doesn't really belong to the section and more about RT America than radiation fears. Would it be okay if I summarised these informations?. I said that the NYT report seems like an op-ed because IMO it wasn't actually accurate and full of baseless accusations. I explained what RT America reported that day about how 5G could cause cancer is not something unusual in the mainstream media but the NYT chose only RT America to attack, then the NYT said that all of radiation fears reports are Russian propaganda. I also pointed out that the NYT report might be biased because it has business relationship with Verizon. I guess I will have to discuss this here WP:V/N.--SharabSalam (talk) 01:35, 19 May 2019 (UTC)
