With the rapid development of network and information technology, people have higher and higher requirements on the number of data in wireless mobile communication networks, which promotes the development of emerging intelligent services, requiring mobile communication technologies to provide faster, more efficient and intelligent networks. technology. Mobile communication technology has also evolved from 2G, 3G, 4G to 5G. Compared with the previous communication technology, 5G mobile communication has obvious technical breakthroughs. 5G mobile will gain broad market development prospects with its unique advantages and key technologies. At the same time, the development of 5G mobile communication technology is also an important achievement in the field of communication.
Second, the application advantages and characteristics of 5G mobile communication technologyIn order to achieve rapid development, 5G mobile communication system will effectively integrate with other wireless mobile communication technologies, which can strongly support the development of mobile Internet. According to the judgment of current insiders, there will be three wireless mobile network service capabilities including 5G in the future. Aspects of application advantages. First, further research and development of new wireless transmission technology to ensure that resource utilization rate is increased by more than 10 times. Second, by creating a new architecture and achieving higher intelligence, the throughput of the entire system will be improved by more than 25 times. Third, vigorously develop new frequencies. Resources to ensure that the frequency resources of future wireless mobile communications will be expanded by more than 4 times.
At present, information technology is developing rapidly and leaps and bounds. Various technologies are realizing reform and innovation. The development of 5G technology has the following distinctive features: First, 5G technology puts user experience in the realization of technological innovation and reform. One, the application of the network in terms of average throughput, transmission speed, 3D, interactive games and other emerging mobile services has been greatly improved, and as a core indicator of 5G technology improvement; second, 5G technology is different from traditional The mobile communication system is no longer limited to the classic technologies such as point-to-point physical layer transmission and channel coding and decoding, but focuses on multi-point, multi-user, multi-antenna, multi-cell cooperation to create new networks. In terms of system architecture, we strive to effectively improve system performance. Third, indoor mobile communication services occupy a key position in various services. Therefore, system design should first consider 5G indoor wireless full coverage, provide stronger business support capabilities, and change mobility. In the past, the communication system used the design concept of “achieving a large scale and supplemented by the interiorâ€; the fourth is 5G shift. More high-frequency spectrum resources are used in communication systems, but because of the limited penetration capability of high-band radio waves, it is necessary to comprehensively apply technologies such as wireless, wired, and optical-borne wireless networking; fifth, 5G wireless networks will also strengthen development research. With the "soft" configuration, operators can adjust network resources at any time according to the continuous development of service traffic, which can effectively save network operation costs and prevent energy waste.
Third, the key technology of 5G mobile communication(1) From the perspective of network technology
5G mobile communication technologies mainly include SON technology, heterogeneous ultra-dense deployment analysis and SDN technology analysis:
First, SON technology. Traditional mobile communication technology has great defects in network maintenance and deployment. Network maintenance and deployment require a lot of manpower and material resources, and 5G mobile communication has effectively changed this situation. SON technology saves a lot of network maintenance and deployment costs, and the use of this technology makes 5G mobile communication gradually move toward the direction of intelligence. However, SON technology is still able to support the coordinated operation of multi-network systems. Therefore, in the future development of 5G mobile communication, it is necessary to optimize the technology and improve its wireless transmission parameters.
Second, heterogeneous ultra-dense deployment analysis. Traditional mobile communication often adopts a method of reducing the radius of a cell when operating a wireless communication system. Under the condition that the radius of the cell is reduced, the system capacity that the user can utilize is also gradually reduced. In the long run, the rate of the wireless network used by the user will be greatly reduced. Therefore, in the future development of 5G mobile communication, it will effectively increase the deployment density of the website and ensure the exquisite user experience. Among each service point, there is a corresponding ultra-dense heterogeneous network. However, in the course of operation, the technology also has a small problem of node spacing and adaptation to dot density. In the future development, the technology will be further optimized.
Third, SDN technology. SDN technology is also known as software-defined networking technology. Compared with the traditional mobile communication technology, the technology of the technology is simpler and also meets the characteristics of efficient and economical Internet. At the same time, the use of software-defined network technology is also very simple, and the user's operation process is greatly simplified. The main principle of SDN technology is to use the central controller to reasonably allocate the wireless resources between the network and the network, so that the management of the wireless network is more convenient, but the problem of monitoring difficulties and unstable state needs to be faced when setting up the network system. In the future, this technology will be further optimized.
Fourth, the conclusionIn summary, 5G mobile communication has gained huge market development prospects with its low energy consumption and high efficiency. At the same time, 5G Mobile's aim of creating a perfect user experience has won recognition from many consumers. The future 5G network will be more flexible, intelligent and efficient using cloud computing technology, including the following three domains: First, access to the cloud. It supports multiple wireless access modes, and combines centralized and distributed wireless access network architectures to adapt to various types of backhaul links for more flexible networking deployment and more efficient radio resource management. The second is to control the cloud. Implement local and global session control, mobility management and service quality assurance, and build an open interface for business-oriented network capabilities to meet the differentiated needs of services and improve the efficiency of business deployment. The third is to forward the cloud. Based on the applicable hardware platform, under the control of cloud efficient network control and resource scheduling, high-reliability, low latency, and efficient load transmission of massive service data streams are realized. In short, with the advancement of society and the development of science and technology, 5G mobile communication will achieve maximum coverage and seek benefits for the majority of users.
