What is a Trust Wallet and how to create an account

The topic of our article today will be about what is the 5G network . It is a huge revolution in the economy, society and our way of life. But that's what well-known companies in the wireless industry believe, and are investing heavily in this development.

But what is the difference between 5G and 4G LTE that everyone knows, follow this article to know all the details 

What is the fifth generation 5G telecommunications?

5G technology is an innovative fifth generation mobile cellular standard. It is designed to provide high data rates with low latency and minimal power consumption. What distinguishes the fifth generation 5G is the increase in bandwidth and support for a large number of connections for each connection tower.

5G technology supports one million connected devices per square kilometer. 

It is also designed to operate over a wider range of radio frequencies, including the ultra-high millimeter wave bands. Since this is a completely new technology, old generation phones are not compatible with this network and a new generation device is required.

5G technology also allows dividing the physical network into several virtual parts. The operators of this network will be able to provide part of the network with a certain capacity depending on the needs of the subscriber, as this step will greatly improve the efficiency of management.

Determining the exact location leads to differences between the use cases of the network between fixed and mobile. Whereas in the first case, we are using the 5G 2022 mobile internet as an alternative to the wired internet.

In some countries, operators sell 5G home Internet service based on mid- and high-band networks. Subscribers usually use this service hundreds of gigabytes per month, which exceeds the capabilities of 4G. As 5G networks have enough bandwidth to meet this demand.

New applications are also waiting for wide coverage of 5G, which will be significantly faster than 4G. So 5G networks can be used in many industries.

The services and applications provided by the fifth generation technology

5G communication technology is almost universal. Where some projects rely mainly on the 5G network , these projects are:

1. Smart cities and smart buildings. With internet sensors able to track and collect data about air quality, energy consumption and city traffic patterns.
2. Manufacturing sector. Artificial intelligence will analyze the vast amount of data it collects to complete procedures that previously required human intervention. For example, quality control and safety. This will allow the use of robots to perform various tasks.
3. The agricultural sector and the environment. Connected devices transmit data related to weather and crop conditions. This will allow the correct distribution of labor, reduce costs and increase productivity. Monitoring the environment and restoring ecological balance in accessible areas will be a reality.
4. Medical care and telemedicine. Thanks to 5G technology, remote diagnosis and surgery will become commonplace, as medical devices will collect health data and easily transmit it to specialists, making early detection of diseases possible.
5. Transfer. Where it will be possible to identify the nearby boats and reduce congestion through a data network of available routes.

Virtual reality will also become more exciting and realistic. People from all over the world will be able to work remotely or play real sports on the field. Virtual stores will appear in different cities around the world.

5G technology also plays a role in augmented reality and the "metaverse". The idea is that if you're going to wear AR lenses on the street, you'll see the commercial reviews that appear on the front doors of the restaurant, talking to the 3D ghosts of the people walking next to you.

Why are 5G networks so fast?

Simply because it has two different frequency bands: 

• Sub-6.
• mmWave.

The former operates Sub-6 below 6 GHz. Sub-6 spectrum is critical for 5G deployment because these radio waves are low frequency and can travel long distances and penetrate walls and obstacles. This means that operators can deploy much more networks without having to build a large number of new cell towers. In short, the low frequency range below 6GHz will provide strong and stable signal coverage.

The second mmWave works with radio waves of ultra-high frequency (24 GHz to 100 GHz) and with a very short wavelength. It is used to speed up 5G connections, allowing for high download speeds.

But high frequency signals cannot travel long distances and overcome obstacles, as even doors or tree leaves can block communication. 

To build the mmWave network, operators will need thousands of small network cells in each city. And you can determine if there is 5G internet in this city by the number of places that can be placed within the city. 

signal delay

The delay, which is the time required to transfer data from one point to another which is 4 milliseconds under ideal conditions and 1 millisecond in cases where maximum speed is required.

Energy Efficiency

Also, 5G technology consumes a moderate amount of power and can switch to low power mode when there is no charging.

5G Cyber ​​Security

Today's cyber defense systems need a very deep modernization because the architecture of the 5G network is much more complex than traditional networks. There are many routing points, each of which requires constant monitoring. Increased bandwidth may result in a revision of network protection methods. The high bandwidth of 5G mobile internet also threatens user security and poses new challenges for specialized application developers.

US carriers have expressed concern about new C-band networks from AT&T and Verizon, saying the frequencies are very close to those used by flight gauges, which measure an aircraft's distance from the ground.

Also, most devices connected to the Internet of Things do not have a firewall. Nor are there even uniform security standards, giving attackers the green light. Whereas, it is necessary to develop a unified cybersecurity mechanism and software solutions. Also, manufacturers of tools for the Internet must increase the level of protection of their products.

What are the phones that support the fifth generation?

There are many smartphones that support the 5G communication standard. But the most popular phones:

1. iPhone 12 .
2. Samsung Galaxy S22+.
3. Google Pixel 6 Pro.
4. Samsung Galaxy A32 5G.
5. Google Pixel 6.
6. Samsung Galaxy S22.
7. Samsung Galaxy Z Fold3 5G.
8. 11S 5G.

You can find out all the devices that support this generation from here .

5G damages

In the real world, actual 5G internet speeds can vary greatly. As in many areas, 5G mobile internet is slow and sometimes slower than 4G LTE. This is usually due to limited spectrum availability.

But this is not the main drawback. As there are many opinions that testify to the dangers of new technologies to the environment and the person himself. Some scientists also believe that 5G can cause mutations and speed up the aging process. The radiation from mobile towers causes the death of migratory birds and negatively affects domestic animals. 

conclusion

5G can make a difference in our lives. Where people, devices, buildings and infrastructure will communicate with each other using this modern technology. And the potential for remote operations, telemedicine, autonomous cars, smart cities and smart factories could come with 5G.

However, we must not forget that high technologies are being developed to solve some global problems. Where people will feel more comfortable, but each new round of high-tech development brings the beginning of a new era. However, not everyone believes that. Special studies have been conducted that have shown that the millimeter waves used in 5G mobile phones themselves do not represent physiological damage.
