What is the 6th generation of mobile communication technology?
The concept of 6G refers to the 6th generation mobile networks or 6th generation wireless systems, which is an extension and upgrade of the 5G system, and the 6G technology aims to achieve higher performance indicators than 5G. It is expected that terahermeth (THZ) bands will be used for communications, and the specific frequency range is mentioned in different sources.
Terahertz band: Commonly referred to as a frequency band between 100GHz and 10thz, this frequency band has a significant frequency increase compared to 5G, and can theoretically provide greater bandwidth and higher data transmission.
6G technical performance indicators:
Transmission speed: Theoretical** speeds may reach 1 terabits per second (TBS), which is a significant improvement over 5G.
Network latency: It will be further reduced to microseconds to meet more demanding real-time requirements.
Connectivity density: Enable connectivity of IoT devices at scale, building a fully connected world that integrates terrestrial wireless and satellite communications, achieving seamless global coverage, even in remote areas.
Application scenarios: 6G will promote the development of the industrial Internet, the Internet of Things, and various intelligent applications, covering enhanced mobile broadband plus, big communications, ultra-reliable low-latency communication (SurLLCC), three-dimensional integrated communication, and unconventional data communication.
China has shown a positive attitude and leading position in 6G technology research and development, and has a high share of patent applications. At present, many leading companies and research institutions in communication technology around the world, including China, are actively engaged in research and development related to 6G (sixth generation mobile communications). In China, companies and organizations that have invested more in the field of 6G and have a certain influence are:
1.China Mobile, China Unicom, and China Telecom are the three basic telecom operators, which not only play a central role in 5G construction, but also are at the forefront of future 6G standard formulation and technology research and development.
2.As the world's leading ICT (information and communications technology) solution provider, Huawei's success in the R&D and application of 5G technology has given it a significant first-mover advantage in the 6G field, and it continues to research and explore key 6G technologies.
3.ZTE is also actively participating in the research and development of next-generation communication technologies, including the pre-research of key technologies for 6G.
4.Hengtong Optoelectronics: It has made a forward-looking layout in the field of terahertz communication, and continues to focus on the research of high-end technology of communication networks.
5.China Satcom: Subsidiaries of the Aerospace Science and Technology Group, such as China Satellite, have an important position in the integrated application of satellite Internet and 6G.
6.Listed companies such as SIEMIC Mobile, Xinwei Communication, and Aoshikang are also involved in the research and development of 6G technology or the production of related products to varying degrees.
7.Shunluo Electronics: Provide supporting core components, and its products are involved in many fields of the communication market, including the possible development direction of 6G - terahertz technology.
8.A number of research institutes under the Chinese Academy of Sciences, such as the Institute of Information Engineering and the Institute of Microelectronics of the Chinese Academy of Sciences, play a key role in the basic theoretical research and core technology research in the field of wireless communication.
9.Beijing University of Posts and Telecommunications, Tsinghua University, Southeast University and other universities, these educational and scientific research institutions have also made important contributions to the research and development of 6G technology, and promote the development of domestic 6G technology through the combination of production, learning and research.
In addition, consumer electronics companies such as Xiaomi, OPPO, and vivo, as well as chip design and manufacturing companies such as UNISOC, are also paying attention to and laying out the future development of 6G technology.
International Aspects:
1.(Nippon Telegraph ** Co., Ltd.) has set up a subsidiary specializing in 6G technology, and has established the IOWN Global Technology Forum in cooperation with Intel, Sony and other companies to jointly promote the development of 6G technology.
2.Other large multinational companies such as Ericsson, NVIDIA, Microsoft, and NEC are also members of the alliance, and they are investing resources to explore and advance 6G technology around the world.
The above-mentioned companies and institutions are involved in the R&D and planning of 6G technology to varying degrees, but the specific technical progress and results may be limited due to commercial confidentiality and R&D stage. With the gradual advancement of 6G technology, it is expected that more companies will join the competition and development in this field.
Finally, in addition to the improvement of speed and latency, 6G technology also involves cutting-edge technologies such as new spectrum utilization, space-air-ground integrated network architecture, artificial intelligence convergence network management, and quantum communication security, and it is expected that 6G will be put into commercial use around 2030 and deployed and applied globally.
