Tianjin Northern Network News:Recently, CCTV news reported that my country is expected to commercialize 6G networks in 2030 and formulate network standardization in 2025. Wang Zhiqin, deputy director of the China Academy of Information and Communications Technology, said: 6G technology is a new technology for 5G intergenerational update. The application scenarios are more at the level of social management and social governance, and are more biased towards intelligent agents.
Future network development direction
With the popularization and maturity of 5G technology, the focus of future network development will shift to 6G. 6G is expected to offer faster data rates, lower latency, and wider connectivity range. Currently, 5G networks are rapidly developing and popularizing around the world, but their popularity varies by country and region. In some countries, such as China, South Korea, the United States, and some countries in Europe, 5G networks have been widely deployed, and user usage is also growing. Especially in the eastern coastal areas of my country, some rural areas have already used 5G networks. However, in other regions, especially in developing countries, the deployment and popularization of 5G networks has remained relatively slow, often due to infrastructure investment costs and technical challenges.
At the same time, the integration of the Internet of Things (IoT), quantum communications and networks, artificial intelligence and machine learning are also important directions for subsequent network development.
6G network refers to the sixth generation of mobile communication technology, which will be the next generation of wireless communication technology after 5G. Although 6G technology is still in the research and development stage as of 2023, it is expected to surpass existing 5G technology in several aspects. Based on the current network development status, it is expected that 6G networks will also be the first to be deployed and promoted in countries such as China, South Korea, and the United States. So what are the characteristics of 6G network?
Since the international standards for 6G have not yet been determined and 6G technology is still in the research and development stage, many discussions about its specific characteristics and capabilities are still in the prediction and envisioning stage. However, according to some public information, the main features of 6G networks are as follows: aspect:
Higher link, transfer speed
The data transmission rate of 6G may reach 50 times that of 5G, and the latency is shortened to one-tenth that of 5G. It is far superior to 6G in terms of peak rate, latency, traffic density, connection density, mobility, spectrum efficiency, and positioning capabilities. 5G will greatly improve download and upload speeds, which means users can enjoy faster Internet speeds, whether browsing the web, downloading files, or streaming media, all will be smoother. It can provide support for applications such as ultra-high-definition video streaming, augmented reality, and virtual reality.
According to current technical plans, 6G networks will use the terahertz band, which can provide wider bandwidth and wider data transmission speeds, thereby reducing latency. Latency in 6G networks may reach microsecond levels, which will be critical for real-time applications such as self-driving cars, remote medical surgeries and industrial automation. Ultra-low latency can improve the mutual response speed between devices. The interconnection between self-driving cars, the movement range of remote scalpels, and the automated processing speed of industrial equipment will all become more accurate because of “low latency”.
Wider link reach
The wider connection range of 6G networks will solve many of the current coverage challenges faced by 5G and enable more comprehensive and universal network access. This will bring greater opportunity and convenience to people around the world, especially in remote and underserved areas. 6G will expand the concept of the Internet of Things (IoT) and enable a wider range of device connections, including devices in extreme environments (such as undersea and space). Currently, Xspace’s Starlink and the satellite call function of Huawei’s Mate60 Pro mobile phone are regarded as a cutting-edge deployment of 6G networks.
will be more closely integrated with artificial intelligence
6G is expected to deeply integrate artificial intelligence technology to realize network self-optimization, management and repair, and provide more intelligent services and user experience.
High construction costs will be a huge difficulty facing 6G networks
Limited by the use of high-frequency networks and the demand for high coverage, “high construction costs” will restrict the development speed of 6G networks. Because according to the current 6G network planning, in the technology research and development stage, various countries, universities and enterprises must invest a lot of manpower, material resources and financial resources to support network construction, such as research and development investment in artificial intelligence, quantum communications and other directions; in order to achieve wider coverage , especially in remote and difficult-to-cover areas, it may be necessary to invest in more infrastructure (such as drones, aircraft) and low-Earth orbit (such as satellite) coverage to provide services for air travel and remote areas.
All in all, 6G networks will provide faster speeds, lower latency, wider coverage and more intelligent network management than 5G in terms of high-speed Internet access, thereby promoting the development of a new generation of digital services and applications. With the popularization and application of communication networks, network security issues have become increasingly prominent. In the future, network security technology will also become one of the important directions for the development of communication networks. By strengthening network security protection and protecting users’ information security and privacy rights, it will help improve users’ trust and experience in communication networks.
