New achievements create the highest true transmission record of wireless communication.
It is understood that the achievement is that Purple Mountain Lab, together with Southeast University, Pengcheng Lab, Fudan University and China Mobile, has realized the 6G terahertz real-time wireless transmission with a single-wavelength net rate of 103. 125Gbps and a dual-wavelength net rate of 206.25Gbps for the first time with the special support of the national key R&D plan, and the communication rate is higher than the current 5G rate of/kloc-0.
Terahertz wireless communication is generally considered as the core component of the future sixth generation mobile communication system. Terahertz frequency band (300GHz~3THz) is extremely rich in frequency resources, which can support ultra-high-speed wireless communication of 100Gbps- 1Tbps. Of course, 6G brings more than just speed changes. It is reported that this achievement can be integrated with the existing optical fiber network to achieve 6G ultra-high-speed indoor and outdoor wide coverage. In the future, it can also be carried on platforms such as satellites, drones, airships, etc., and can be applied to high-speed wireless communication scenarios between satellite groups, between heaven and earth, and over 1000 km, realizing integrated air, land and sea communication.
The transmission capacity of 6G is 100 times that of 5G.
5G is useless, 6G is here? After seeing the news, many netizens questioned, what is 6G?
6G refers to the sixth generation mobile communication technology, which mainly promotes the development of the Internet of Things. It is understood that the transmission capacity of 6G may be 100 times higher than that of 5G, and the network delay may also be reduced from millisecond level to microsecond level.
Last September, 16, China IMT-2030(6G) Promotion Group held the first 6G seminar. On behalf of IMT-2030(6G) Network Technology Group, Duan Xiaodong, Vice President of China Mobile Research Institute, released the white paper "Vision of 6G Network Architecture and Key Technology Outlook" at the meeting. According to the white paper, the future 6G will further realize the leap from the Internet of Everything to the Internet of Everything on the basis of 5G. In the future, 6G services will show the development trend of immersion, intelligence and globalization, forming eight business applications, such as immersion cloud XR, holographic communication, sensor interconnection, intelligent interaction, communication perception, inclusive intelligence, digital pairing and global coverage.
The deployment of 6G networks may begin in 2030.
So, when will 6G arrive? At present, according to the industry-recognized law that mobile communication iterates once every 10 year, 6G will appear around 2030. Xiang Ligang, a communication expert, further explained: "The formulation of the 6G vision will be completed around 2023, which means what we want to do with 6G. 6G standards may be formulated by 2028, and 6G networks may be deployed by 2030. "
At present, China's 6G development has also achieved excellent results. According to the survey results of relevant Japanese institutions, in the list of 6G core technologies, China's 6G technology patents accounted for 40.3%, ranking first, and the United States' 6G technology patents accounted for 35.2%, ranking second. Japan ranks third, accounting for about 10%.
Experts thousands of miles away operate on patients, remotely operate excavators and other equipment in air-conditioned rooms, and let Hainan people experience the joy of skiing in the north through 5G+VR ... At present, all walks of life are constantly exploring new application scenarios of 5G, and 6G will make the vision of 5G better realized.
Beach also said that in the future, users will feel more directly about 6G, and the traffic will increase from the current GB to TB. At the same time, 6G may bring some new network service modes. "At present, people are used to operators providing networks and base stations. In 6G, users are not only users of the network, but even providers of the network. "
