Key technologies and application scenarios from 1G to 5G
| key technology | Application Scenario | |
|---|---|---|
| 1G | analog communication | Realized the combination of "mobile" capability and "communication" capability, which became a milestone in the development of mobile communication system from scratch, and opened the prelude to the evolution of mobile communication system. |
| 2G | Comprehensive transition from analog to digital systems | Start to expand the supported business dimensions |
| 3G | CDMA | Improved support for mobile multimedia services |
| 4G | MIMO and OFDM | It has further improved the spectrum efficiency and supporting bandwidth capabilities, and has also become the basic support of the mobile Internet |
| 5G | massive MIMO, mmWave transmission, multi-connection | Achieved all-round improvements in peak rate, user experience data rate, spectrum efficiency, mobility management, latency, connection density, network energy efficiency, and regional service capacity performance |
3 progressive stages of the relationship between AI and humans
- AI is a super assistant (oracle) for human beings. It can understand and master all the psychological and physiological characteristics of human beings, and provide timely and accurate life and work suggestions for human beings, but the decision to accept the suggestions is in the hands of human beings;
- AI has evolved into a human super agent (agent), and has taken over part of the decision-making power from humans, and it has full authority to handle affairs on behalf of humans;
- AI has further evolved into the sovereign of human beings, becoming the master of human beings, and all human actions are subject to the arrangement of AI.
6G Service Requirements Framework
The virtual world created by 6G can build an AI assistant (AIA, AI assistant) for each user, and collect, store and interact with what the user says, sees and thinks. Specifically, the virtual world system includes three spaces: 虚拟物理空间(VPS, virtual physical space), 虚拟行为空间(VBS, virtual behavior space), 虚拟精神空间(VSS, virtual spiritual space
-
Based on the real-time massive data transmission of 6G-compatible typical scenarios, VPS constructs the mirror image of the real physical world (such as geographical environment, buildings, roads, vehicles, indoor structures, etc.) in the virtual world, and provides information interaction for massive users' AIA virtual digital space. The data in VPS has the characteristics of real-time update and high-precision simulation, which can provide business support for major sports activities, major celebrations, emergency rescue, military operations, simulated e-commerce, digital factories and other applications.

VBS extends 5G
mMTC场景. Relying on the 6G human-machine interface and biosensor network, VBS can collect and monitor the physical behavior and physiological functions of human users in real time, and transmit diagnosis and treatment data to AIA in time. Based on the analysis results of the data provided by VBS, AIA predicts the user's health status and gives timely and effective treatment solutions. The typical application support of VBS is the universal realization of precision medicine. -
Based on the massive information interaction and analysis of VPS, VBS and business scenarios, VSS can be constructed. Due to
语义信息理论the development of the Internet and the improvement of the ability to perceive different needs, AIA can obtain various psychological states and spiritual needs of users. These perceived needs include not only real needs such as job hunting and social networking, but also virtual needs such as games and hobbies. Based on the perceived needs captured by VSS, AIA provides comprehensive suggestions and services for users' healthy life and entertainment.
Genie — spirit
- Genie exists in the virtual world system and can be
通信和决策formulated without human participation. Based on a large amount of data collected in real time and efficient machine learning technology, Genie completes the acquisition of user intentions and decision-making. Genie can serve as a 6G userAIA, providing powerful proxy functions. Through human-machine-thing-spirit collaboration, Genie can provide users with real-time virtual business scenarios and act on behalf of users to realize corresponding needs.
