6G's policy push:
Cai Lian News Agency, March 5, the minister of industry and information technology said at the first "ministerial channel" of the two sessions that the mainland has built the largest and most technologically advanced 5G network, and now our country has ranked among the top in the world in terms of 5G. There are more than 575 million 5G mobile phone users in mainland China, and 600,000 new 5G base stations will be opened in 2023, bringing the total to more than 2.9 million. The 6G Promotion Working Group is already working to strengthen international cooperation and accelerate the research and development of 6G.
According to the 6G technology test plan of the IMT-2030 working group, 2022~2024 is the key technology test stage, and the main technical directions of 6G will be clarified, and the concept prototype test verification will be carried out to improve technical capabilities. Facing 2030 and beyond, 6G will achieve full-spectrum utilization, space-space-ground integrated coverage, intelligent interconnection of man, machine and things, rich application scenarios, and comprehensive improvement of key performance and technical indicators, relying on breakthroughs in key technologies such as new air interface and transmission technologies and network architecture.
The difference between 6G and 5G:
(1) More powerful network capabilities:
According to the world's first 6G white paper "Key Drivers and Research Challenges for the Omnipresence of 6G Wireless Intelligence" released by the University of Oulu, Finland, most performance indicators of 6G will be improved by 10~100 times compared with 5G. For example, the peak transmission speed of 6G reaches 100Gbps-1TBPS, and 5G is only 10Gbps; The indoor positioning accuracy is 10cm, and the outdoor positioning accuracy is 1m, which is 10 times that of 5G; The communication delay is 0.1ms, which is one-tenth of 5G, ultra-high reliability, the probability of interruption is less than one in a million; ultra-high density, the density of connected devices reaches more than 100 per cubic meter.
(2) Richer application scenarios:
On the basis of the three major application scenarios of 5G - eMBB (enhanced mobile broadband), URLLC (ultra-high reliability and ultra-low latency communication), and mMTC (massive machine communication), 6G will add two application scenarios of artificial intelligence and perception.
6G fully supports human-centric immersive interactive experiences and efficient and reliable IoT scenarios, and builds application scenarios such as ultra-wireless broadband (immersive cloud XR, holographic communication, sensory interconnection), ultra-large-scale connectivity (digital twin), extremely reliable communication (machine control), inclusive intelligent services (intelligent interaction, intelligent interconnection), and communication perception fusion (multi-dimensional perception).
Application of 6G in the metaverse:
Compared with the basic application scenarios implemented by 5G, 6G can provide millisecond-level latency, ultra-high bandwidth, and guaranteed security and reliability for application scenarios such as immersive XR, holograms, and sensory interconnection in the metaverse. 6G far surpasses 5G in key performance indicators such as peak rate, network performance, mobility, latency and jitter, reliability, and coverage, providing users with a smooth, stable, and secure immersive interactive experience.
(1) The implementation of 6G networks, combined with the improvement of XR terminal equipment capabilities, can help the metaverse enter the era of full immersion. In the future, the cloud-based XR system can realize various interactions between users and the environment, such as voice interaction, gesture interaction, eye interaction, etc., and 6G can provide ultra-high bandwidth and ultra-low latency to meet the smooth and real-time interactive experience of users in Metaverse Review.
(2) In the future, holograms will replace traditional smart screens and become one of the interactive methods of the metaverse. The realization of holograms requires powerful image transmission capabilities and powerful spatial 3D display capabilities, and 6G can provide them with ultra-high bandwidth and ultra-low latency data transmission capabilities, as well as ultra-high data transmission security and reliability.
(3) In 2030 and the future, the effective transmission of sensory information will become one of the mainstream communication methods, in order to support the transmission of sensory information, it is necessary to ensure the consistency and coordination of auditory, visual, tactile and other sensory information transmission, which will require the data transmission network to have millisecond delay characteristics. 6G can provide millisecond-level latency for the transmission of sensory information, as well as guaranteed safety and reliability.
6G Market Size Forecast:
Market Research Future predicts that the global 6G market will exceed $340 billion in 2040, with a compound annual growth rate of 58.1%. The agency believes that China will be one of the world's largest 6G markets, and China will also be an early adopter of 6G technology.
6/5G Industry Chain:
6G related subjects:
Satellite-related targets: Chengchang Technology, Xinke Mobile, Zhenyou Technology, Shenglu Communication;
Underlying infrastructure, IT and network equipment targets: ZTE, Unigroup;
Optical device suppliers: Zhongji Xuchuang, Tianfu Communication, Yuanjie Technology;
Midstream telecom operators: China Mobile, China Telecom, China Unicom;
Third-party data center operators: Runze Technology, Kehua Data.
Potential Risks:
(1) The uncertainty risk caused by Sino-US technology competition to the industry.
(2) The development of 6G is not as expected.
(3) The risk of changes in relevant national industrial policies.
According to the general prediction of experts, 6G technology is expected to be commercially available around 2030, but before the official commercial use, there are still many challenges in the research and development of 6G technology; If you want to develop 6G technology, you need to lay a good foundation for 5G, only in this way can we make 6G development more solid.
