Fifth Generation: 10 facts about 5G
The fifth generation of wireless is more than just fast internet in your pocket. Perhaps this technology will change the world beyond recognition.

5G is an abbreviation of the fifth generation of English, “fifth generation”, which is after the current telecommunications standards 4G. With the advent of this technology, experts promise to accelerate mobile data transfer – a hundred times faster than 4G. In practice, for the average user, this means that an Ultra HD film can be downloaded in one or two. But the main thing, of course, is not this, but the fact that the 5G would make it possible to automate what previously only man relied on. Autonomous cars will be able to drive around the city, instantly analyzing road conditions. In “Smart Home” all devices will be able to communicate with each other. Real-time communication in areas of natural disasters will be uninterrupted. Scientists have promised quite incredible things like remote robotic surgery.

Another promised 5G benefit is the support of millions of devices per square kilometer. This is important for operators, as the population density is higher in cities and growing faster in places. At the same time, everyone wants high-speed internet, and 3G and 4G can no longer cope with this load. Even between cities and cities, the number of high-speed highways and railways is increasing. 4G still works at speeds up to 200 km / h, but 5G networks have the potential to use high-speed Internet at speeds up to 500 km / h. Some modern trains run a little slower.

And 5G developers promise that users cost significantly less energy than 4G. This means that despite the huge speed and high-quality content of the device, the phone battery will run very slowly.

At the heart of 5G’s “philosophy” is the so-called Internet of Things. It is a technique that combines peripheral devices, such as sensors, and information processing centers, into a single network, where the collected data is analyzed. After processing the information, orders are issued to other devices. For example, in the event of a gas leak or smoke, the signal is transmitted to the appropriate services. At the same time, the coffee maker makes fresh coffee, and the toaster roasts the bread, while the landlord takes a morning shower – almost like Ray Bradbury. Of course, this will change the global economy, no doubt. Experts talk about the trillions of dollars of new annual sales secured by 5G.

But the Japanese want to use 5G to track the health of cash cows. This should make life easier for farmers, especially beginners. In a large herd, it is not easy to monitor dairy cows. On the first symptoms of mastitis, treatment should be started so that the disease does not worsen. It is also important not to miss the time when the cow needs to be artificially aired – this is only possible during the daytime every three weeks. The future system will transfer photos from cameras in gaushalas to data processing modules, and the farmer will get all this information on the smartphone screen.

5G development plans were announced when 4G was not heard in 2014. In 2018, it began launching test networks in various countries. The first commercial continuous usage was conducted a year ago in South Korea. The experiment was not completely successful: many users criticized the quality of communication, saying that 5G services were not really as fast and reliable in advertising. Meanwhile, 5G was launched in several cities in China, the United States and Switzerland. Of course, all were widely involved in test launch and measurement media. Ericsson experts announced that at the end of last year, about 13 million people had already tested the fifth generation network in the world.

In Russia, the first experiment began in 2018. An example is the 5G network covering the entire small town – Cronstadt, now it is a remote area of ​​St. Petersburg. Tests were carried out in the Hermitage, and in Moscow – in Skolkovo, in the Moscow City business center and near City Hall, on the Towerskaya Street from the Kremlin to the Garden Ring, as well as in some areas, for example, in Teststan. .

Operators have stated several times that they want to test and configure 5G devices to operate in the so-called gold range of 3.4–3.8 GHz. At medium frequencies 2–6 GHz, which includes this range, the signal is more stable, and the data transfer rate is higher. For 5G, this segment is optimal, and in Europe, commercial networks use it. In Russia, the frequency range 3.4–3.8 GHz is currently used by law enforcement agencies and specialized communications.

The prospect of 5G distribution has been exciting activists from various countries for over a year. They worry about the potentially harmful effects of technology on the human body: the nervous and reproductive systems, and more. Cases of strange behavior of animals, birds and insects in areas where they have experienced a new standard of communication. It is curious that insurance companies do not have a unanimous opinion on the matter, and many of them have so far refused to insure the liability of telecom corporations that filed claims against them for health damage caused by 5G . There are no sensible scientific publications on this subject. Other problems may arise in the future. For example, mass distribution of devices with a network connection is extremely convenient for all types of hacker attacks.

Although many foreign operators have already launched a 5G commercial network, at the moment it is nothing more than entertainment, and there is still a long way to go to utilize the full potential of the standard. countries like India is far behind in this matter but has its advantages. Meanwhile, new and newly successful tests are the main news event regarding 5G.
