Samsung Electronics
Studies and tests show that the ultra high at 28GHz
Frequency band
With a speed of more than 1Gb per second, it successfully achieved data transmission within a range of 2Km. Until now, no company or organization in the world has developed a data transmission technology of more than Gb per second in the ultra-high frequency band above 6GHz, because it is difficult to solve the problem of short transmission due to the distortion of the UHF wavelength segment.
With the adaptive array transmission technology of 64 antenna units, Samsung Electronics is able to transmit radio waves over long distances, track the location of the user terminal in real time, and download and exchange data. The success of ultra-high frequency band data transmission technology not only ensures higher data transmission speed, but also effectively solves the problem that mobile communication band resources are nearly exhausted.

(2) The stability of 5G network communication technology transmission.
5G network communication technology has not only improved the transmission speed, but also made outstanding progress in the stability of transmission. The application of 5G network communication technology can carry out very stable transmission in different scenarios and can adapt to a variety of complex scenarios. Therefore, 5G network communication technology is very practical in the actual application process, and the improvement of transmission stability reduces the difficulty of work. When working with 5G network communication technology, the transmission capability of 5G network communication technology has high stability. Therefore, it will not cause too long transmission time or unstable transmission because of the complex scene of the work environment, which will greatly improve the work efficiency of the staff.
(3) High-frequency transmission technology of 5G network communication technology.
High frequency
Transmission technology is the core technology of 5G network communication technology, and high-frequency transmission technology is being studied by many countries at the same time. Low-frequency transmission resources are increasingly tight, and the operation and use of 5G network communication technology requires greater frequency bandwidth, and low-frequency transmission technology can not meet the work needs of 5G network communication technology, so it is necessary to be more proactive to explore and develop. High-frequency transmission technology plays an important role in the application of 5G network communication technology.

1. Vulnerability of virtual network technology
For 5G network technology, although it shows more obvious convenience characteristics compared with 4G network technology, it still has the inherent vulnerability characteristics of virtual network. In the actual application process, compared with the physical communication means, it is easier to be attacked and stolen, and in serious cases, it will lead to the destruction of its terminal means. In the actual operation and application of the communication network, malicious attacks are often disguised as legitimate users, and in the case of obtaining the trust of the network communication service, they will carry out attacks, and the malicious damage in the network is often difficult to eradicate it, and it is difficult to eliminate it in time. In addition, for the application of mobile network, it is necessary to support smart devices, but network technology and smart devices will be subjected to certain malicious attacks in practical applications, so the security of 5G network in the practical application process will still be affected.
2. 5G network makes computing and storage technology and equipment face more severe tests
In the practical application process of 5G network, there are increasingly high requirements for data access channels, which require higher transmission speed. However, most devices in practical applications cannot meet this requirement, which will inevitably have a certain adverse impact on the application of 5G network. In addition, in the actual application of 5G network technology, there are also new requirements for the management mechanism of the terminal. Due to the existence of these factors, it is difficult to build a more effective transmission management system in the practical application of 5G network technology, and the emergence of information overload will also lead to faults in the actual operation and application of equipment, resulting in an adverse impact on the application of 5G network.
3. Network business security issues
In the continuous improvement and development of 5G network technology, in the future e-commerce and related value-added services, 5G network technology will inevitably have more and more extensive applications, and in the actual development of such businesses, there are also higher requirements and standards in terms of equipment security and information security. As far as the intelligent system used by users is concerned, it shows very obvious liquidity characteristics, and it will inevitably involve different operators, service providers, and information exchange parties in the actual circulation process. The communication between these different links has higher requirements in terms of security, and 5G networks will inevitably face security tests in future practical applications.

At present, network communication technology is still developing, and the data transmission rate will be greater than 10G/s in the near future, and remote control applications will be widely used in people's lives under such a premise. In addition, the 5G network communication delay is short, about 1ms, which can meet the practical applications of remote control with higher precision requirements, such as vehicle automatic driving, electronic medical, etc., and further improve the security of 5G network communication remote control applications through shorter network delay, and constantly improve the functions.
(2) Strengthen network compatibility.
For different networks, compatibility has always been a common problem faced by its development links, only to solve this problem, you can greatly improve the share of the corresponding technology in the market. But the current situation shows that no network communication technology has good compatibility, and even if it does, there are serious limitations. However, one of the most significant features and advantages of 5G network communication is strong compatibility, which can meet the normal use of different devices in the application and development of network communication, and effectively integrate networks of different types and stages, greatly increasing the number of people applying 5G network communication, realizing the compatibility of different network systems at different stages, greatly reducing network maintenance costs and saving costs. Get maximum economic benefits.
(3) Coordinate and make reasonable plans.
The mobile market is developing rapidly, and there are a variety of communication systems in the market. If 5G network communication wants to gain a foothold in the fierce market competition, it is necessary to coordinate and reasonably plan a variety of network systems, coordinate the management of multi-standard networks, and allow users to obtain high-quality services and experiences in different environments. Although 5G network communication has the advantages of communication technologies such as 3G and 4G, it is necessary to realize the collaboration of multiple networks to maximize the advantages of 5G network communication, so in the process of applying 5G network communication, the central system is used
Resource manager
Promote the decoupling of users and data, optimize network configuration, and achieve the goal of load balancing.
(4) Meet business needs.
The fundamental goal of the application and development of network communication has always been to meet the needs of users. From the 2G era to the 4G era, people's demand for network communication has become more and more diversified, and network communication technology has also been improved in all aspects. The application of 5G network communication is bound to meet the needs of users, optimize the user experience, and achieve no blind corners and all-round network coverage. Users can enjoy high-quality network communication services wherever they are located, and ensure the stability of network communication performance regardless of remote areas or cities. In the future application and development, one of the most important goals of 5G network communication is to achieve the stability and independence of network communication services without being affected by geographical and traffic factors.
