The oceans are smoking and the bad news is that that phrase is starting to stop being a metaphor

by

Global sea surface temperature is once again approaching 2024 records, Arctic ice marks its historic winter minimum and the average temperature is 1.43 degrees above pre-industrial levels. What’s more, the Earth’s energy imbalance has reached its highest level in 65 years. And all of this without El Niño being active. So I have to correct myself: what is happening is not that the sea is smoking. That’s a huge understatement. What happens is that the oceans have gone up a notch and we are completely caught out of the game. What is happening? According to Copernicus dataIn March, the global average temperature was 13.94 degrees. That is 0.53 above the 1991-2020 average and 1.48 above the pre-industrial temperature. It’s not the warmest March on record, but it’s close. In contrast, February 2026 was one of the three coldest in the last 14 years. And it’s curious because, anyway, we are in ENSO-Neutral conditions. The 2024 record was reached with El Niño pumping heat from the Pacific; Now we are in the most absolute normality. That does have experts from half the world worried. And the sea? In the sea things are more complicated because the surface temperature is very close to lrecord ace of 2024. Furthermore, it is not a question of a specific rebound: it is the result of a sustained rise throughout the entire month of March. There are specific areas (subtropical and northeastern North Atlantic, North and South Pacific) that are already at record values; The big question is what will happen at the end of the year and, above all, at the beginning of the year when El Niño is at its highest peak of intensity. Well, but this doesn’t affect us much, right? It depends on what we mean by ‘affect’, of course. What there is no doubt is that, despite the fact that temperatures are rising around the world, the Mediterranean has become the great laboratory for all detected and undetected climate risks. After all, Mare Nostrum heats up to 20% faster than the global average. And that has clear and direct consequences for water: from the mass extinction of vertebrates to the decline of grasslands to an enormous mortality of fish. Is a sea dying little by little; a sea that drags us with it: because the heat of the Mediterranean injects more water vapor and fuels extreme precipitation phenomena. The DANA of Valencia It’s a reminder of all this.. That is, the scenario is known. What remains is to see what we do to prepare for it.

James Webb has bad news for the largest natural laboratory for rocky planets, but there is still some hope

by

The star TRAPPIST-1 and the seven known planets that surround it are a natural laboratory in which the evolution of rocky planets can be studied. This has led many scientists to focus their attention on them, in search of a possible habitable planet. However, observations made by an international team of astronomers with the help of the James Webb Space Telescope They are not very encouraging. Planets without atmosphere. The James Webb Space Telescope has a very powerful infrared radiation analysis instrument, with which it can analyze the temperature of the planets it observes. These emit infrared radiation whose intensity is proportional to their temperature, so a thermal map can be made. That’s what these astronomers have done. They have initially focused on two of the planets that orbit TRAPPIST-1: TRAPPIST-1a and TRAPPIST-1b. The resulting heat map shows that neither planet has an atmosphere. They may have had it one day, but possibly TRAPPIST-1 itself destroyed it. It is a very uninspiring result for the search for habitable planets in this system. Lights and shadows of TRAPPIST-1. So far seven exoplanets have been discovered orbiting TRAPPIST-1. They are all very close together. In fact, its seven orbits are concentrated in the distance between Mercury and the Sun. What happens is that this red dwarf is less energetic than our Sun, so the temperature would not be as suffocating. All of these planets are rocky, like Earth, and in fact, some are very similar in size. There could be an exoplanet with conditions similar to ours. The problem is that red dwarfs They emit a lot of radiation and energetic flows of particles that could destroy their atmosphere.. And of course, without atmosphere, there is no life. Tidal lock. All planets in the TRAPPIST-1 system are tidally locked. This means that its rotation and translation period around the red dwarf they are synchronized. As a result, there is one side continuously exposed to the star and another on the opposite side. On one side it is always day and on the other it is always night. NASA/JPL-Caltech Extreme temperatures. When a planet is tidally locked, there can be two situations, depending on whether it has an atmosphere or not. When there is an atmosphere, heat flows from the light side to the dark side, so that the entire planet has a stable average temperature. On the other hand, if there is no atmosphere, the dark side can be frozen and the illuminated side can be scorched. In the two exoplanets analyzed by James Webb, it has been seen that temperatures are around 100ºC-200ºC on the illuminated side and -200ºC on the dark side. Therefore, it is confirmed that there is no atmosphere. And now what? Despite this hard blow, there is still hope. The two exoplanets that have been analyzed are not in the star’s habitable zone. This is the distance from it at which the temperature is adequate for the water, if any, to remain in a liquid state. At that exact point there are only TRAPPIST-1e, TRAPPIST-1f and TRAPPIST-1g. Furthermore, the former has a density and size very similar to those of Earth. James Webb has all his attention on this exoplanet right now, to repeat the process. If there were an atmosphere on it, it could still remain on the list of possible habitable planets. It’s still interesting. Despite the first blow, TRAPPIST-1 remains a very interesting system for understand the evolution of rocky planets. The Earth was lucky not to lose its atmosphere; but, beyond those, the evolutions can be similar. Furthermore, we have not yet ruled out that TRAPPIST-1e has an atmosphere. Let’s go step by step.

We already know where many of the microplastics that enter our body end up. We have bad news

by

That microplastics had managed to enter our body is something that we already knew in detail, especially considering that we have found them in the lungsin the placenta and even in the testicles. However, there were questions about where they accumulated in greater quantities in our body and what consequences does it have. Something that science has already solved. What they have seen. It has been thanks to a recent study published in the journal Environmental Science and Ecotechnology that it has finally been revealed that not only can cholesterol crystals be found in bile that end up generating stones, but also there are microplastics. And the worst of all is that they have a direct impact on the premature aging of the cells that make up our gallbladder. How do you know? To reach this conclusion, the researchers analyzed 14 samples of human bile: five from healthy patients without gallstones and nine from patients with gallstones. The results were conclusive, since they found microplastics in the samples, mainly highlighting two of them. the most common polymers in our daily lives: polyethylene (PE) and polyethylene terephthalate (PET). Here it could be seen that the particles had a size that ranged between 20 and 50 micrometers. A very relevant fact, since from these sizes is when they can cross the biological barriers, cross the intestine-liver axis and end up in the gallbladder of our liver. There is more. In addition to the presence of plastic in the bile, it could be seen that patients who had gallstones showed a higher load of microplastics. Something fundamental, since it is a fact that fits with recent research that suggests that these particles could act as ‘seeds’ around which cholesterol groups to form the dreaded stones in the gallbladder. What do they do? This is the key point of these studies, since we still do not have much idea of ​​the damage that microplastics can do to our body. Here it points out that bile causes mitochondrial dysfunction and promotes the aging of cholangiocytes, which are the cells that line the bile ducts. In previous experiments, it was possible to see that in the liver of laboratory mice exposed to environmental concentrations of microplastics there was alteration in the metabolism of bile acids and liver damage. In the case of humans, which increases oxidative stress. But the important thing is that in both cases the bile duct cell loses its ability to function correctly and ages prematurely, which in the long term could be related to liver and bile duct diseases. Can it be mitigated? Among the bad news, scientific literature suggests that there are ways to avoid it. One of the great protectors that exists is melatonin, suggesting that it can combat oxidative stress and mitochondrial dysfunction generated by these synthetic intruders. In parallel, other recent experiments with human liver organoids have shown that the damage caused by microplastics improves when ursodeoxycholic acid is administered, which is the drug administered to ‘dissolve’ gallstones. The ‘magic’ of this compound is that it increases bile flow, suggesting that promoting a kind of natural “washing” of the bile duct could help reduce toxicity. A problem. The confirmation of bile as a “hidden reservoir” of microplastics highlights an undeniable reality: plastic pollution is no longer just an environmental problem in our oceans, but a systemic public health problem about which we know more and more data. The longer-term consequences, such as the relationship with gallbladder cancer, remain to be seen.

It takes 7,000 GPUs to simulate a tiny quantum processor. Although it may not seem like it, it is excellent news.

by

The complexity of quantum computers It is extraordinary. In their construction it is possible to rely on several very different strategies, such as, for example, superconducting qubits, ion traps or neutral atoms, among other technologies, but they all have something in common: to a large extent its power is a consequence of its complexity. Of the complexity inherent in any device designed to take advantage the laws of quantum physics. The surprising thing is that, despite its sophistication and exoticism, it is already possible to accurately simulate a small quantum processor using conventional hardware. In fact, has achieved it a research group from the Quantum Systems Accelerator and the Division of Applied Mathematics and Computational Research at the University of California at Berkeley (USA). This is not the first time that a quantum processor has been simulated, but until now no one had managed to do it by emulating every physical detail before its manufacture. A new era begins in quantum chip design Here’s a shocking fact: the Berkeley researchers I mentioned in the previous paragraph have carried out their simulation of a quantum chip using the Perlmutter supercomputer, which contains 7,168 NVIDIA GPUs. To achieve their purpose, they used almost all of these GPUs for 24 uninterrupted hours, so it is evident that the computational effort was titanic. But they got it. They managed to model a multilayer quantum chip 10 mm wide and 0.3 mm thick, accurately simulating how signals travel and interact within this processor. This statement from Andy Nonaka, one of the scientists at the Berkeley Quantum Systems Accelerator, express clearly Why this milestone is so important: “I am not aware of anyone who has ever performed physical modeling of microelectronic circuits at the full scale of the Perlmutter system.” “I’m not aware of anyone having ever done physical modeling of microelectronic circuits at the full scale of the Perlmutter system. We were using almost 7,000 GPUs (…) We divided the chip into 11 billion grid cells and were able to run over a million time steps in seven hours, allowing us to evaluate three circuit configurations in a single day. These simulations would not have been possible in this time frame without the complete system” What really what makes the difference is precision with which they have managed to carry out the design and simulation of their quantum processor. “We perform a full-wave physics-level simulation, which means we care about what material is used in the chip, its design, how the metal is wired (using niobium or other types of metal wires), how the resonators are built, what the size, shape and material used are (…) We care about those physical details and we include them in our model,” Nonaka says. A priori we can conclude that using almost 7,000 GPUs for 24 hours with the computational effort and energy expenditure involved in this process to simulate a quantum chip just 10 mm wide and 0.3 mm thick is not a success. But yes it is. Thanks to this technology, it will now be possible to design quantum hardware in less time and in a more efficient way. Bert de Jong, director of the Berkeley Quantum Systems Accelerator, invites us to look towards the future of quantum computing with optimism: “This unprecedented simulation is a critical step in accelerating the design and development of quantum hardware. More powerful, higher-performance chips will unlock new capabilities for researchers and open new avenues in science” Image | Generated by Xataka with Gemini More information | ScienceDaily In Xataka | We already know what the chips that will arrive until 2039 will be like.

There is a way to open the dishwasher incorrectly. This is bad news for your kitchen furniture.

by

Practically half of Spanish homes have a dishwasher. And some of the most reputable manufacturers have had to come to the fore to explain why. it’s not a good idea Open the door as soon as the washing cycle ends. Don’t be craving. Opening the dishwasher as soon as the wash cycle is finished is not the best idea, according to the manufacturers themselves. Some, like Boschrecommend waiting for it to cool a little before opening the door so that less steam comes out of the opening. Others, such as Siemens, make exactly the same recommendation: let the appliance cool down slightly after the program ends before opening the door. Because. Opening the dishwasher at the end of the cycle is not particularly dangerous, but it can cause problems in your kitchen in the long term. Manufacturers point out that excess steam when opening the door when it is still quite hot can end up damaging kitchen furniture. Similarly, dishwashers use their own residual heat to help the correct drying process. All this without taking into account the most obvious detail: if we open the appliance when it is full of high-temperature steam, we run a greater risk of suffering a slight burn. How the dishwasher works. To understand why the dishwasher generates so much steam at the end of the cycle, it is worth doing a brief review of how it works. Basically, it is a closed circuit that allows hot water to be pumped into rotating arms. When you choose the program, the door closes. Water enters its base and the dishwasher heats it. When the water is hot, the pump pushes it under pressure into your arms. The water hits the dishes and drags away the dirt. The detergent is released and begins to break down grease and food debris. The residual heat dries the dishes little by little. The heat problem. Aware that opening the dishwasher as soon as it is finished is common practice in homes, manufacturers have been devising solutions for years to prevent excess steam. Some appliances of this type have an automatic opening system. The door opens just a few centimeters to let the steam out little by little, so that when we finish opening it manually we avoid that initial blow. Other systems, even more advanced, they use zeolites. Zeolites are microporous aluminosilicates (of mineral or synthetic origin) that have a crystalline structure with a huge internal surface area. When they absorb water molecules the process is exothermic, that is, they release heat. This allows part of the steam to be collected and used as waste heat for drying. Increasingly advanced solutions to address a problem as simple as it is common. In Xataka | A user bought a next-generation connected dishwasher. That’s where his nightmare began

SpaceX is now a company in the railway sector and it is very bad news for its employees

by

For some people it will be ingenuity, for others a very hard face, but the point is that SpaceX has found a way to avoid lawsuits and strikes by its workers when obtaining the name of air transport company. This means that it is regulated under the Railway Labor Law, with all the benefits that it entails within US legislation. The news. On March 13, the official resolution was made public by which SpaceX, Elon Musk’s space agency, is now considered a company in the railway sector in the United States. This means that your activity is no longer subject to the supervision of the National Labor Relations Board (NLRB)which is typically responsible for protecting the labor rights of private sector workers. The layoffs that started it all. In January 2024, the NLRB put a lawsuit against SpaceX on the tableafter the company illegally fired 8 employees. The lawsuit requested reinstatement of the employees, back pay, and a letter of apology to each of them. Given this situation, SpaceX responded with another lawsuit to the NLRBalleging that the procedure being carried out was unconstitutional. Rockets have the same legal treatment as cargo planes. An ace up your sleeve. According to Elon Musk’s company, the NLRB should not be able to act against a company that is dedicated to transportation. He added that One of its main missions is the transport of humans and goods to the International Space Station.. In many cases, these jobs are carried out for NASA, so they would also be providing a service to the Government. For all this, they requested to be covered under the Railway Labor Law. A plan that suits many. In recent years, SpaceX, as well as other Elon Musk companies, have been the subject of complaints from a multitude of dissatisfied employees, either due to their personal situation or due to bad practices carried out in the company. In the case of Neuralink, for example, Very bad practice towards laboratory animals was reported. But returning to SpaceX, the increasing volume of complaints could put the company’s work pace at risk. This, logically, would harm its managers, but also the companies that benefit from its services. The entire US space program would probably collapse. For all this, although it seemed difficult, in the end Elon Musk’s company has had a resolution in favor of its new name. Immune to strikes. One of the peculiarities of railroad companies in the United States is that they benefit from special state protection. Since minimum transport services must be guaranteed, strikes and other similar activities that would normally slow down the normal pace of work are closely controlled. The NLRB no longer rules. Another of those special protections for railroad companies is that the NLRB no longer has power over them. Therefore, dismissed employees cannot resort to it to report their situation. Instead, the company is governed by the rules of the National Mediation Boardmuch more lax in the mediation of labor disputes. It is true that employees can request strikes, but to do so they must undergo a long and tedious process that often causes them to change their decision. And now what? With this new name, SpaceX has even more power and freedom than before. If measures are carried out that involve malpractice towards employees, it is difficult for their complaints to come to fruition legally. This gives them a lot of leeway and greatly speeds up their protocols. Other curious legal victories. It is not the first time that SpaceX has obtained an unexpected legal name. Last year, for example, The Starbase base was given the name of cityso that all employees who live nearby would also become inhabitants. This, far from changing a few patterns, also gave SpaceX more freedom when maneuvering in the areas surrounding its base. As with railway legislation, what may seem like a small name change can change everything.

The good news is that the Ebro reservoirs are at a historic 85% water level. The bad thing is that we are going to spend it in a short time.

by

There are 6,640 hm3 of water in the Ebro basin. The reservoirs are at 85.1% of its total capacity at what is its highest level (for this date) of the decade. And yet, the fact that there is a lot of water is not news. All of Spain is the same (83.3%). The news is that we are going to spend it. A structural problem called ‘Mediterranean’. Every year, the pressure of the Mediterranean summer and the irrigation campaign empty the reservoirs very quickly. AND, as history has shown usthere is never too much water: “each dry period has served to implement emergency measures for agriculture that were not eliminated when the rains returned, they were used to expand irrigation, aggravating the problem in the following drought”, said Ana Tudela and Antonio Delgado. And that, precisely that, is what we are about to see. The complete image. Seeing the figures for the reservoirs can lead us to forget that, just three years ago, 85% of the basin’s surface was in “prolonged drought“and 45% of them declared themselves in shortage emergency. Mequinenza, the largest swamp, reached historic lows. It was a catastrophe not only in water terms, but also in energy terms. Now, however, all that is in the past. And Say’s Law lurks in the dark. What the old French economist Jean-Baptiste Say argued at the end of the 19th century is that “every supply creates its own demand“and, translated into this situation, this means that the fact that there is more water generates all the incentives in the world for there to be more irrigation. As soon as we do it, this becomes clear. After all, not all of the basin’s storage capacity is enough for a full year of agricultural demand. Without the annual rainfall and the melting of snow, we could already consider all its reserves exhausted. March is the key month. The irrigation campaign runs from April to September and that means that March is the key month for planning the year. It is true that the thaw has not yet begun (which this year is going to be very intense), but it helps us estimate what quantities of water are really available. All irrigated agriculture in the valley depends on the water we are able to store during the spring. The question from now on becomes: how do we conserve as much water as possible before we once again enter a situation of risk? And the problem is that we don’t have answers. Especially in a regulatory context in which are not foreseen widespread restrictions on irrigation. Economic, social and institutional incentives tell us that we are not yet prepared, as a country, to address the really important question: we do not have a water problem, we have a consumption problem. There is still room for improvement in management, yes. But that won’t solve the problem: it only postpones it. And that 85% of reservoir water has given us unbeatable weather, we just have to hope that we can take advantage of it.

Beijing just gave the best news to NVIDIA

by

NVIDIA has been caught in the crossfire of the trade war between the United States and China for more than a year. Its most powerful chips could not be sold to the Asian giant because Washington required export licenses and later Beijing did not give the green light to imports. This week the two fronts have been unlocked simultaneously and Jensen Huang has taken advantage of his annual developers conference to announce it out loud. Your factories they are starting enginesand the future is brighter than ever for her. H200 chips, unlocked. The H200 chip, NVIDIA’s second most powerful chip today, had become the center of trade and technological tensions between China and the United States. The Trump administration had already granted export licenses but of course, as long as she got her cut. Which was missing it was him approval from Beijingthat according to Reuters It has arrived this week for many of the customers who were demanding access to these chips. Among them are ByteDance, Tencent, Alibaba and DeepSeek. China is a gold mine. Before the restrictions imposed For the US, China represented 13% of NVIDIA’s total turnover. The export veto was highly criticized by Jensen Huang, who did not stop criticize the measureof try to avoid it and to explain that what the US had done was not protect its technology, but rather shoot itself in the foot. During this blockade, Chinese companies have been advancing both in the development of AI models and in the development of their own chips. They still have room for improvement, but this effort to “become independent” from US technology is already bearing fruit and perhaps would not have occurred if it were not for the US veto. There will also be Groq chips. NVIDIA will not only export its H200 chips, but is preparing a version of its AI inference accelerators for the Chinese market. Specifically, we are talking about Groq chips, a company in which NVIDIA invested $20 billion to “license” its technology, although In practical terms I have acquired it. These chips are especially interesting because they are not used to train AI models, but to execute and “serve” them. This is the market that is growing the fastest right now, and where competition is toughest. But China already has inference chips. Companies like Baidu they are already producing its own inference chips, which means that NVIDIA will not enter the Chinese market from a monopoly position, but as another competitor. What is striking here is the fact that Groq chips are not refined versions nor are they adapted to this market according to the cited sources. in Reuters: They will be the same ones that companies in the US or other parts of the world use. China will continue without access to Vera Rubin. This week NVIDIA presented a new line of products built around its next AI chips, the Vera Rubin. These chips cannot be sold to China due to current restrictions, so at NVIDIA they have found a hybrid architecture: Vera Rubin for markets where it can operate freely, and Groq as an inference component for China. NVIDIA is brimming with optimism, and with good reason. Jensen Huang spoke precisely in his inaugural conference about how promising the company’s future looks. Previous projections spoke of medium-term revenues of $500 billion for its Blackwell and Rubin chips. Inference solutions and this “opening” to China now mean that this forecast is doubled: Huang hopes to achieve at least $1 trillion in cumulative orders by 2027a simply dizzying figure that makes it clear that NVIDIA’s business seems to be in an enviable state of health.

China already has two chip manufacturers with 7nm technology. This is very bad news for the US and its allies.

by

SMIC (Semiconductor Manufacturing International Corp), the largest Chinese semiconductor manufacturer, has the capacity to produce 7nm chips from 2023. At the beginning of September of that year this company shook up the integrated circuit industry by demonstrating that it had been able to manufacture these semiconductors despite not having access to UVE photolithography equipment (extreme ultraviolet) produced by the Dutch company ASML. These highly sophisticated machines are necessary to manufacture cutting-edge chipsand ASML cannot sell them to its Chinese customers because the US, which controls some of the patents used by this equipment, prohibits it. Still, in 2023 SMIC and Huawei worked hand in hand to manufacture 7nm ICs without using ASML’s EUU machines. Of course, they used deep ultraviolet (UVP) equipment that this company from the Netherlands also produces. UVP machines are not as advanced as UVE machines, but with proper refinements they can be used to manufacture cutting-edge integrated circuits. And now China has two semiconductor manufacturers capable of producing 7nm chips. As we have just seen, one of them is SMIC, and the other, according to Reutersis Hua Hong Semiconductor, the country’s second largest integrated circuit producer. The shadow of ‘multiple patterning’ is very long Hua Hong Semiconductor’s division specializing in third-party chip manufacturing is called Huali Microelectronics, and, again according to Reutersis preparing to start production of 7nm integrated circuits at its Shanghai plant. The sources that have revealed this information assure that Huawei has collaborated with Huali Microelectronics on this project, which invites us to reach two reasonable conclusions. It is very likely that with the help of Huawei, Huali has developed ‘multiple patterning’ techniques The first is that Huali’s 7nm lithography will most likely play an essential role in GPU production capacity for artificial intelligence (AI) from both Huawei and other Chinese companies. And the second conclusion is actually a plausible hypothesis. And, like SMIC, Huali does not have access to ASML SVU equipment. For this reason, it is very likely that with the help of Huawei it has developed security techniques. multiple patterning to be able to manufacture 7nm chips with the UVP machines in its possession. A priori, UVP machines are suitable for manufacturing semiconductors up to 10 nm. And with EUVs it is possible to exceed 3 nm. However, by refining the processes involved in transferring the pattern to the wafer and turning to multiple patterning It is possible to go beyond these integration technologies. This technique broadly consists of transferring the pattern to the wafer in several passes with the purpose of increasing the resolution of the lithographic process. It may have an upward impact on the cost of chips and a downward impact on production capacity, but it works. Either way, Huali Microelectronics is going to face the same challenges that SMIC has dealt with for the last three years: the multiple patterning seriously limits the number of viable chips per wafer that is possible to manufacture. And, therefore, it increases its cost. Still, it is very important for Chinese AI chip designers to have access to two companies capable of producing their designs with advanced photolithography technology. And for Hua Hong Semiconductor it is crucial to have the ability to manufacture, thanks to Huali, cutting-edge integrated circuits and not just 22 nm or larger (this is the most advanced photolithography it had so far).

MásOrange has begun to completely dismantle its 3G network. Not good news for elevators

by

If you are one of those who usually browse even on a 3G connection, we have a curious fact: you are from the club of 1.82% of global traffic. The operators carry years saying goodbye to this networkand MásOrange has been the last to take the step. The operator is going to say goodbye to its 3G network for good reason. Hello to 5G. MasOrange has been the last of the large operators to start with the shutdown of 3G. Vodafone finished turning off its networks two years ago, and Telefónica is about to finish the process. With the release of the spectrum used by 2G and 3G connectivity, operators have additional bands to reinforce 5G technology. Specifically, the 900 and 2,100 MHz bands allow expanding coverage in areas with lower population density without the need to build new towers. A progressive plan. Although 2G and 3G connections sound completely obsolete, they are still necessary to connect a good number of day-to-day technologies. Elevators Cars with eCall system with 2G modules Telecare services security cameras Home alarms Old dataphones For this reason, the plan to dismantle the Spanish 3G network is being carried out progressively, giving time for a good part of these devices to update their connection modules. Although 3G was scheduled to say goodbye forever between 2025 and 2026, current plans keep it alive until 2030. A great challenge ahead. The 3G network continues to be a great ally, both for older devices and for times when 5G coverage does not have range. The challenge now is, precisely, that the deployment of 5G is even greater. For three decades, 3G invaded every corner of Spain, and some of the networks it uses (900 MHz) are especially good at passing through walls and operating in rural areas. Therefore, in complicated areas your mobile still connects to 3G. The end. Maintaining 2G and 3G networks is unsustainable. The radio space they occupy is especially valuable and, although there are devices that still use old technology, their dismantling is necessary.
