Correction to what I say at 15 mins 57 seconds: It's should be 3 orders of magnitude, not 30.
You'd think that technology and science make a good team, and most often that's true, but every once in a while they get into a big fight. One such case is the 5th generation of wireless networks, 5G for short, that's become a big headache for meteorologist because millimeter waves interfere with the weather forecast. On that occasion I also tell you about a recent review on the health effects of 5G and what 6G may bring.

    Thing is, if we didn't do things that were bad for us, we'd literally be living in the preindustrial revolution. And while our modern stuff kills a LOT of people percentage wise, it also saves a LOT of lives. Considering that the death rate for those 5 years old and you get was 30% in the Early 1800's(and that's just from the diseases we have vaccines for). Modern tech is an overall benefit. For now anyway. Won't be long before it's not with how global warming is going.

That's roughly equivalent to the World Metereological Organization saying "We'd like you to limit this to the power of a single LED, please" and the USA saying "Eh, we'll limit it to 250 Suns. That'll be OK." (By the way, I'm not suggesting that Sabine isn't scientifically literate. Just that it's a really bad mistake for a scientifically literate person to make.)

The impact on commercial utilization is tolerable, and the loss of the scientific utilization is not. I'd say this one is pretty clear cut, even if it means a trip back to the drawing board. I like the apparent European approach - just hold off on auctioning those bands for now.

    In 2013 we discovered I had a “terminal” case of Non-Hodgkin’s Lymphoma. My baseline PET scan, prior to treatment, showed a dense inguinal tumor the exact size and orientation of the antenna in my iPhone (per engineering teardown). I had always kepy my phone in my pants pocket juxtaposed to where we found the tumor. No one in the medical community wanted to report this black-and-white finding to state or federal regulatory agencies. The reason, they stated, was that the telecom industrial complex was too powerful and wealthy - nothing would come of it, other than risk to my doctors. I was fighting for life for several years, so we had no appetite to pursue the matter. Big money doesn’t care about the everyday person, and their corruption has now gripped governments.

    A couple of points, 5G is used on several bands, not just mmWave. In fact it's often used on the exact same bands as 4G, 3G, 2G and 1G. It's just expanded to include mmWaves. That said, mmWave is a huge spread, with only part of it close to the frequencies used by vapour detection. In fact, there a 4 mmWave bands allocated for 5G and only one of them is near it. The other 3 are further up the spectrum. So, it's just a small piece of the mmWave spectrum that's the problem, not 5G in general. Incidentally, there is another area where 5G is getting unwarranted blame. That's with the with the n77/n78 band, which starts at 3.3 GHz. This is close to the frequency used by radio altimeters, as used on aircraft. There was a lot of noise from the aviation community about this. However, it turns out no one bothered to do any testing. They just assumed. Turns out it's a problem with certain older altimeter models that had inadequate filters. Adding a filter fixes that problem. Also, aviation regulators have often ordered equipment upgrades, as technology advanced. Certainly that vapour detection must be considered, with spectrum allocated and equipment designed appropriately to avoid the problem. One method that's often used is called a notch filter, where a filter is used to block specific frequencies. This combined with the usual band pass filters would likely remove the problem.

    @@Rokin365 I'm not sure what your question is. First off, as I mentioned, is that many assume 5G means only mmWaves, which is not the case. However, any other band has nothing to do with the issue of measuring moisture. This video is somewhat vague in a lot of ways, so it's hard to pin down what she's saying. Regardless, this is a technical issue with potential interference that has to be considered. For example, how much power is actually transmitted? Does it produce frequencies that actually interfere? Is it possible to reduce the interference? Regardless, if there is significant interference from mmWave 5G, then it might be best to not use frequencies so close to what is used for moisture detection. This isn't the first time such has happened. For example UHF TV channel 52 (IIRC) was not used in North America, so as not to interfere with radio astronomy. Balancing radio spectrum users is an ongoing challenge that has both technical and regulatory solutions. I mentioned the aircraft altimeters, where the fix is to just put a filter ahead of the affected devices. As for CTIA, I'd always be wary of what an industry spokesman says, as they are not unbiased. The moisture issue will take proper study before those bands come into common use. Also, given the short range of those frequencies, they might be used mainly indoors, in stadiums, air ports, etc., in which case the problem might not exist.

    Indeed the highest band around 90 GHz is intended for large crowds with a direct line of sight. It is ideal for temporarily locations like concerts, large crowds can be served at once with relatively little hardware, without overloading the fixed antenna network. And the lowest band is ideal for iot applications, 5G is a very broad specification both for industrial applications and consumer telecommunications. From technical point of view it is a very well thought specification and a major milestone, but for most people it's just 'faster'.

    One quibble: when Sabine talks about the future capabilities of 6G she mentions the enablement of various use cases with “instantaneous access.” This is not quite true. 6G provides greater bandwidth (as 5G did, and 4G before that), but *latency* is not as dramatically imoroved. Many of those science fiction applications also demand very low latency in addition to large bandwidth. Getting lower latencies is possible, but it can be a more costly engineering problem to address.

    4G and 5G offered a huge improvement on latency. To make latency much shorter than sub 10ms we have to start bringing services nearer to consumers, perhaps away from those huge server facilities, which will still be used for higher latency applications and data storage. But a round trip from, let's say Helsinki to Berlin is a minimum of 11ms and the fiber optics don't run straight. The latency wirelessly from phone to that fiber is brought close to a minimum already, as well as how many bits can be squeezed in bandwidth unit.

Hurricanes form over open ocean, not over land. McToon makes these points in the video linked in this comment.

    @@jonasdaverio9369 Personally I also have little idea how it works; as far as I know, satellites don't directly measure either of those; instead, they measure the intensity of certain EM wavelengths, and different intensities correspond to different temperatures, and different temperatures correspond to different altitudes since the atmosphere varies in temperature as you go up or down. Then there's one range of wavelengths for measuring clouds and such, and another range for measuring water vapor specifically; the amount of water vapor etc. can then be inferred based on the measured intensities (e.g. if the intensity reading indicates a high altitude, that means there's probably a lot of water vapor, because the light is being reflected back from a high altitude, meaning there's probably a lot of water vapor piled up in the area) I assume the two wavelengths react with a measurable difference to the presence of water droplets, so they can probably make some kind of calculation to separately determine how much water is in droplets vs. vapor, but really meteorology is way beyond me and I have no idea how they figure these things out with any level of confidence It's also possible Sabine did mean the water in cloud droplets (rather than water vapor, as she said), but I am nitpicky so I assume she meant what she said

    So wind generations systems are HUGE. They are in areas void of other development because that's where the wind blows. Wind blows because giant air masses at high pressure seek pressure equalization by moving to low pressure air masses. Of course there are many other factors but the measurements needed are not super high tech. These systems are giant and changes occur slowly. Predictions in these areas are extremely precise, better than 95%, 1 full day ahead and about 80% accurate 2 full days ahead. These air masses are giant and changes occur slowly. Predictions in these area are outstanding. Rain measurements are not useful for this. And, network carriers would not deploy 2.5GHz systems in these areas due to wave propagation fade, and no people. 5G is a format not a frequency band. 5G works great on 600, 700, 800 MHz, or anywhere else you'd like. PV is another story. Energy production varies substantially as visible moisture shades the cells. However we only need dew point and temp aloft to predict. Precision is not as good but decent. It's typically correct but can miss unexpectedly. Not even counting the previous 2.5 GHz auction, the FCC collected $416M. For that price, in fairness, shouldn't they ensure proper design? Shouldn't they be held accountable? Well, they are not. Telecom companies paid, and paid, and paid. When that was done, they paid again.

Careful analysis has shown the issue is really the bad filter designs in the radio altimeters, they let in too much energy from nearby frequencies. After much back and forth the FAA has now mandated that the radio altimeters have to be upgraded. I looks like this is a similar situation. I realize the changing a filter on a satelite already in orbit is not an option, but going forward the satellite designers need to use better filtering.

While the avionics industry's plan to sit on their hands and hope that nothing happens was irresponsible and ultimately didn't work, it's important to see that what the bug-eyed conspiracy theorists are doing is something entirely different. They're trying to will a "problem" into existence by shouting "wolf" repeatedly, and hoping that a wolf then appears. Equally bad planning, but coming from an opposite direction of illogic. The way pseudoscience works is to pick a conclusion first, then go cherry-picking for evidence that supports the conclusion, ignoring evidence that contradicts it. But when there is no evidence?

    Harmonics are a well known problem in transmitter design, and the higher the power output the higher the harmonic amplitudes. Designers use low pass filters to reduce harmonic amplitudes, but that only attenuates them as a source of interference. In addition the more data you transmit on a channel the broader the sidebands become. So I'm inclined to agree with the leakage concerns. The 5G industry should be well aware of these concerns since this stuff is taught to any EE major in their communication systems course.

True, some frequency at half, or a third of the frequency may generate harmonics that interfere, but then blaming "5G" for that is not at all honest.

    Unlicensed 24 GHz is even closer to the weather satellites and they have been used for over a decade. They are used for rooftop point-to-point dish links. 25 GHz 5G is much further from the weather satellite. They are also aimed horizontally in a narrow beam so the spurious output and sideband leakage to the 23 GHz weather radar is a non-issue. If it was going to be an issue the unlicensed 24 GHz would pose a bigger problem.

    I'm surprised that the engineering issues were not mentioned. 5G was mentioned in another YT video a while ago as needing an order of magnitude more power from both phones and cellphone towers; and due to the different EM bandwidths used, cellphone towers (or whatever they are called) also had to be built much closer together to provide coverage. The additional power requirements alone appeared to make provision of a 5G service uneconomic, at least in the location in China where this was being discussed. My memory is not that great and of course the internet is renowned for dubious claims, so I have no idea whether this power issue (which will also affect battery life of phones and other mobile devices) is valid or not. I'd love to hear more from someone more familiar with this new technology though.

    In the UK the 5G frequencies are on the same frequencies previously used by television stations for many years. TV broadcasts are at a higher power level than 5G transmitters because there were fewer of them and they were further apart. You could fry an egg on a TV transmitter. You can't even warm your hands on a 5G transmitter. There has not been any publicly announced massive increase of any illnesses that corresponds with TV frequencies in the UK over the years so I have no concerns.

They could have chosen to give it no name and continued to call it 4G indefinitely. It's just the evolution of the specification. The specifications constantly improve, add more features, increase speed, etc. It is necessary because there are more cell phones and other cell devices every day. And the request for data from the network increases every day.

    Acknowledge the concerns of the technical experts during design rather than grudgingly acknowledge them during implementation? Crazy talk! There's a similar situation in software, where experts in what's practical to implement are often not consulted until after many key design decisions have been made. Sometimes I wonder if such workflows are deliberate, driven by experience/fear that involving the experts early means the beautiful product vision gets crushed and the project goes nowhere. The attitude seems to be that projects proceed best when the experts are put on the back foot, forced to come up with a quick compromise in a high pressure situation, rather than being allowed the time to come up with an optimal solution at the start.

    Thanks Dr. SH for another wonderful video on this topic. I would like to add my own thoughts as typical of any couch dwelling expert who watches a bunch of KZread videos: These generations of technologies absolutely need to be developed. This will be essential in the future. While it has many earthly advantages, it will be much more essential for interplanetary communications. However, 1) There's a capitalistic play here which is causing a bit of an issue. Scientific research and development now a days seem more tied to corporate bottomline than ever before. Corporations (such as AT&T, T-Mobile, Vodafone, Telenor etc.) needed 5G faster than the scientific community and research facilities could have it refined and properly evaluated. These corporations also sit in the board of these research organizations and support the research with actual funding. Therefore they have the full control of what gets put out and when. Just a basic example various 3G technologies are actually still getting refined under the guise of 5G. All through 4G we were mostly getting a set of 3G technologies refined every so often. Now that many of these companies have deployed "5G" the reality is that, 4G is finally being deployed in its full glory while 1 OR 2, 5G specific technology has also been deployed in a few specific tower of the highest density and most convenient (for deployment) area. This makes these corporations not liars while showing the public that they are constantly innovating and are on top of their game. I don't see this pattern changing I.e. we'll see 5G technologies to start roll out en masse under the guise of 6G and be fully refined by the time 7G is around. 2) Our phones saying 5/4/3G does not say anything about what technology it's actually using. The wireless carriers along with the phone manufacturers decide what the phones report to us. 3) The most important gain from generation upon generation of wireless communication technology actually has been the improvement in latency not the bandwidth. Of course bandwidth has improved significantly, but latency is most important factor to determine the quality of a communication channel. This is not easy to grasp because most of us are not well versed in communication protocols and their wireless kins. High latency has severe impact on how well these protocol functions. For example it's possible for the latency to get so high that the actual communication comes to a crawl while bandwidth remains up there, this is because bad data packets are jamming the channel. Analogy: let's say I only speak Japanese and another person I'm going to communicate with speaks only Italian. I can directly speak Japanese to this person and there will be 0 communication. I could remove noise and be in a quite room with this person and speak as loudly as necessary but there's 0 communication. I won't understand the Italian and this person won't understand Japanese. This is high bandwidth but extremely high latency. I could have a Japanese to English translator and other person could have English to Italian translator. In the same low noise environment, now we have managed to reduce the latency down to high but tolerable level. we could have communication but despite potential for very fast communication our translator bottleneck causing latency is not 0. Of course anyone can figure out how to improve the latency in this scenario. The thing to realize is that it's impossible to fully eliminate this latency for our actual wireless communication scenario, because: a) we are not able to eliminate noise, and wireless medium will always have unpredictable amount of noise, increasing frequency of the radio waves to the point that it becomes as close to flat line as possible is the way to eliminate noise at which point we've transferred over to straight line Fibre optics channel. However, I think the future physicists will be able to solve this problem of medium. b) we have to always have translation layer because at the level of usable communication we are using disparate systems and protocols (which make up the internet)

    Regarding health affects, the airport security detectors use mmWave in the 24-30 GHz range so if there is a problem it would have been apparent. Note you receive million time more energy from the phone than what you receive from a tower because of the distance you are from the phone vs the cell tower. Regarding the leakage, 400 MHz is a fairly large guard band and is easy to measure. 3GPP in Geneva does specify the roll off of the signal. Guard bands between communication channels in the bands are in the 1 to 2 MHz range, hence I don’t see issues with 5G

    Majority of the 5G deployments in Europe use 3.5 GHz band and there seems not yet be actual demand for mmWave. Also the 5G mmWave has performance challenges and it is currently mainly limited to be used for fixed wireless access. mmWave and sub-THz communications require beam-forming, but pointing those very narrow beams to mobile phones is very difficult… It remains to be seen if this problem can be solved. If not, the 6G 100GHz links will be just point-to-point links connecting the base stations to the core network.

    5G uses the exact same bands and air interface (COFDM) as 4G. mmWave will never be deployed, as WiFi calling is better.

    @@James_Knott you are correct; the BT WiFi (which does voice & data) is managed entirely by their app, so no user config is required, the SSID is hidden, but known to the app, as is the passcode, so zero config, it just works. There may be more bands in the US, but only sensible bands, below 2.5GHz will be used.

My carrier, Rogers, uses all of the available bands, as far as I can tell, including the 5 GHz WiFi band, at least for LTE. Does that BT app require any action by the user?

    FYI: 4G and 5G is really just a protocol that dictates how the towers and the phones talk to each other. 5G can use the exact same frequencies as 4G - and it actually does in most markets. The problem is with idiotic carriers who want to be able to advertise the insane speeds only capable with mmWave, despite it being completely impractical - even your own hand can completely block mmWave from reaching your phone. It's a complete waste of spectrum even before you take into account the weather predictions issues. With all that said, 5G as a protocol is actually a huge upgrade over 4G in terms of reliability - the extra speed is just a marketable bonus. If we could just reallocate all the old 3G & 4G spectrum and use it for 5G, then things would be great. Unfortunately, that would require everyone in North America to replace all their legacy devices, so that's not happening anytime soon.

    Totally agree, though in a macrocellular environment, 4G is already pretty damn good so we may be operating at the point of diminishing returns even in low and mid-band spectrum. The thing 5G does offer in the lower bands is more carrier aggregation and combination possibilities, which can be used to give a higher peak rate. The benefits of this remain to be seen, though, since they only marginally increase capacity, and those peak rates will be hard to see in a crowded environment. The focus on mmWave is really boxing 3GPP technologies into direct competition with Wi-Fi in terms of the realistic use cases, e.g. in-building, short range. But it does it at a MUCH higher cost (about 10x the cost). Maybe it shouldn’t be surprising that 5G has mostly been a flop.

    Sabine, I have a BS in electrical engineering so for once I understood everything you said. Most of the noise problems can be overcome using the most basic filters on both the transmitters and receivers, this particular issue has been ongoing for a century. This is like the general problem of noise floor for most telecommunications already. As for the safety of 5G, my employer forbids us from approaching 5G towers closer than 5 meters but I see the 5G antennae much closer to homes than that. We might need aluminum hats or live in faraday cages or both.

    I don't understand electronics well enough, but I guess that narrow filters are far from basic. From video - 23.80 frequency should be protected from 24.25 - 27.50 range. What order of filter will be needed for it to happen?

    Isn't it easier to filter a 400MHz different signal at 30 MHz than at 28 GHz? It is a much smaller percentage. I'm curious and always thinking and learning. Edit: If it is so easy, why the big fuss over aircraft landing systems and 5G cellular frequencies?

    What mmWave really does is allow much higher density. You can serve faster data to a lot more people in a small area. 5G includes mmWave, among other technologies. 5G itself mostly allow network operators to reduce cost and complexity. In a lot of cases, 4G/LTE works perfectly fine and the transition to 5G does not include mmWave. But not everywhere.
