Learn about 5G from scratch

1.Overview of 5G

The so-called 5G network refers to the fifth-generation network in the development of mobile communication networks. Compared with the previous four-generation mobile networks, the 5G network shows more enhanced functions in the actual application process, and theoretically its transmission The speed can reach tens of gigabytes per second, which is hundreds of times faster than 4G mobile networks. For the 5G network, it shows more obvious advantages and more powerful functions in the actual application process.

The 5G network is currently a new type of network, and its penetration rate is still relatively low, and further research and development are still needed. For any kind of network, network security issues are very important influencing factors, and the same is true for 5G networks. Therefore, 5G network security issues need to be paid more attention to. As a 5G network researcher, you should strengthen your understanding of 5G network security, and pay more attention to it, actively solve 5G network security issues, and grasp its development direction, so as to achieve a more ideal development of 5G network, so that it can be more and more widely used in the future application.

2.Advantages of 5G

2.1 High spectrum utilization

At present, the utilization of high-frequency spectrum resources is greatly restricted. Under the current scientific and technological conditions, the utilization efficiency will be affected by the penetration of high-frequency radio waves, and generally will not hinder optical carrier wireless networking and limited and unlimited broadband Widespread use of technology combinations. In 5G mobile communication technology, high-frequency spectrum resources will be widely used.

2.2 The communication system performance has been greatly improved

The 5G mobile communication technology will greatly improve the communication performance, taking the joint cooperation and networking of a wide range of multi-points, multi-antennas, multi-users, and multi-cells as the main research objects, making great breakthroughs in performance and updating The concept of the communication system under the traditional form.

2.3 Advanced design concept

The core business of the mobile communication business is indoor communication, so if you want to improve the mobile communication technology, you must optimize the indoor communication business. Therefore, the 5G mobile communication system is committed to improving the coverage performance of indoor wireless networks and improving the support capabilities of indoor services, breaking through the traditional design concepts to form an advanced design concept.

2.4 Reduce energy consumption and operating costs

Energy consumption and operating costs have a great impact on the development of science, so the development direction of communication technology is also towards lower energy consumption and lower operating costs. Therefore, the "soft" configuration design of 5G wireless network is the main research object of future mobile communication technology. Network resources are dynamically adjusted in real time according to the usage of traffic, so that energy consumption and operating costs can be reduced.

3.The future trend of 5G

5G is the most cutting-edge technology of mobile communication technology so far, and it is the performance of the highest level of communication technology. According to the actual situation, the country hopes that the future 5G communication technology can develop in two directions, one is the Internet, and the other is the Internet of Things, dedicated to solving the massive communication problems of existing machinery.

On the one hand, with the development of Internet technology, 5G network communication is also undergoing rapid development and improvement, and Internet technology will also become a platform for the development of network communication technology in the future. At this stage, mobile communication technology is being updated relatively quickly, and it generally takes a decade or so from the idea to the realization of the technology to the final technological maturity and commercial application. And every cycle from the beginning to the end can be a huge technological advancement.

On the other hand, the development of mobile Internet technology also provides a better research foundation for the development of 5G mobile communication systems, enabling 5G mobile communication networks to have higher-quality transmission and system efficiency technologies. In the future, with the development of 5G mobile communication technology, its technology will be significantly improved in three main aspects. First of all, in terms of wireless transmission, 5G communication technology has expanded the width of wireless mobile communication, leading to a further increase in communication frequency. Secondly, compared with 5G mobile communication technology, the utilization rate of wireless communication frequency is higher, and better communication functions are realized. In addition, compared with traditional 2G, 3G, and 4G mobile communication technologies, 5G mobile communication is more user-friendly in terms of user experience, especially in terms of interactive games and 3D support capabilities, which can give users a better user experience. Finally, the 5G mobile communication system has also greatly improved its indoor mobile communication services. Under the influence of the new 5G communication technology, the coverage rate of wireless signals is higher, realizing better indoor mobile signal communication.
