Technical principles edit
Samsung Electronics has shown through research and experimentation that in the ultra-high frequency band of 28GHz, at a speed of more than 1Gb per second, it has successfully realized data transmission with a transmission distance of 2Km. Previously, no company or organization in the world has developed a data transmission technology that achieves Gb-level or more in the ultra-high frequency band above 6 GHz. This is because it is difficult to solve the problem of short transmission due to the easy distortion of the ultra-high frequency wavelength range.
Samsung Electronics uses the adaptive array transmission technology of 64 antenna elements to make the long-distance transmission of radio waves possible, and it can track the location of the user terminal in real-time to realize the data upload and download exchange. The success of ultra-high frequency band data transmission technology not only guarantees a higher data transmission speed but also effectively solves the problem of the near-exhaustion of mobile communication band resources.

The 5G network communication technology has not only improved the transmission speed but also made outstanding progress in the stability of the 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. The increase in transmission stability reduces the difficulty of work. When staff use 5G network communication technology for work, the transmission capacity of 5G network communication technology is highly stable. Therefore, it will not cause too long transmission time or unstable transmission due to 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 simultaneously by many countries. Low-frequency transmission resources are becoming tenser and tenser, and the operation and use of 5G network communication technology require a larger frequency bandwidth. Low-frequency transmission technology can no longer meet the work requirements of 5G network communication technology, so it is necessary to explore and develop more actively. High-frequency transmission technology has played an important role in the application of 5G network communication technology.
Security issues edit
1. The 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 fragility characteristics of a virtual network. In an actual application, it is easier than physical communication means. Being attacked and stolen, severe cases will lead to the destruction of its terminal means. In the actual operation and application of communication networks, malicious attacks often pretend to be legitimate users, and they are attacked when the trust of network communication services is obtained. Such malicious damages appearing in the network are often difficult to eradicate. It is difficult to eliminate it in time. In addition, for mobile network applications, smart devices need to be supported. However, network technology and smart devices will be subject to certain malicious attacks in actual applications, so the security of 5G networks in actual applications will still be affected.
2. 5G network makes computing and storage technology and equipment face more severe tests
In the actual application of 5G networks, there are also higher and higher requirements for data access channels, which require higher transmission speeds. However, most devices in actual applications cannot meet this requirement. This will inevitably have certain adverse effects on the application of 5G networks. In addition, in the actual application of 5G network technology, there are also new requirements for management mechanisms in terms of terminal management. Due to the existence of these factors, it is difficult for 5G network technology to construct a more effective transmission management system in the actual application process, and the emergence of information overload will also cause equipment failure during actual operation and application, resulting in 5G network The application is adversely affected.
3. Issues concerning the security of online business
With 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 widespread applications. In the actual development of this type of business, equipment security and information Security also has higher requirements and standards. As far as the intelligent system used by users is concerned, it exhibits very obvious characteristics of liquidity. In the actual circulation process, different operators, service providers, and information exchange parties are also involved. Communication has higher requirements in terms of security, and 5G networks will inevitably face the test of security in future practical applications.
Development prospects edit
At present, many countries around the world are racing to develop 5G network technology, and China and the European Union have invested a lot of money in the research and development of 5G network technology.
In a 5G shortcode discussion solution at the 87th meeting of 3GPP RAN1 held on November 17, 2016, with the support of 59 representatives, Huawei defeated Qualcomm's LDPC and France's Turbo2 with Polar Code. .0 plan won the right to speak in the 5G era.
