Although the 5G era has just arrived. Recently, the University of Moru at Finland has published more than 70 experts with 6G white papers to introduce the technical trend of the 6G era. However, this is also in line with the development trend of communication technology.
When 4G developed, Huawei, Nokia, Ericsson, etc. are already pre -research 5G technology. The R & D cycle of each generation of communication technology takes about 10 years. In fact, as early as April, the world’s first 6G summit hosted by the University of Oru. The main purpose of the summit is “paving the road for 6G.”
According to this white paper, 6G networks will be launched around 2030. Its vision is generally on wireless intelligence, which means that 6G networks will cover all corners of the world through wireless technology to provide more intelligent perception services and applications for human society.
After each generation of the mobile communication network is upgraded, its performance will be increased by 10-100 times. Of course, the 6G performance will also be increased by 10-100 times on the basis of 5G. Therefore, on the specific technical indicators, the following new changes will be produced:
• The maximum transmission rate of single users reaches 1Tbps
5G expands from less than 6GHz to the millimeter -wave band. 6G will enter the era of Tahz (THZ), and the network capacity will be greatly increased.
• 0.1MS (extreme industrial control scenarios)
• Positioning accuracy up to centimeter level
• The equipment synchronization is delayed in 1 μs
• The density of the connection device reaches hundreds of cubic meters
And 6G will also have super safety and super reliable
As well as
Data privacy protection, artificial intelligence and wireless network integration and other characteristics.
Professor Pouttu at the University of Finland said that people have interconnected between people, so 5G or 6G commitments will be more objects. From the perspective of delay, the near -time connection of 5G has not been completely resolved: For some “strict time requirements” application, the latency of the millisecond (MS) level is not good enough, so there is still great potential to upgrade communication capabilities to upgrade communication capabilities Essence When you start to process a large amount of information, you can reach the TB/S -class communication rate from the beginning. When increasing the data rate, it is necessary to increase the frequency — its range from 100GHz to the frequency of Terahertz (THZ).
In the 6G era, edge computing will become a development trend. Facing the huge number of Internet nodes and massive data, the total amount of data can only be used to calculate the processing capacity of the edge side can meet the needs of the intelligent era of all things. Essence
The small -scale cloud data center that distributes distributed at the edge of the network and provides real -time processing and analysis decision -making is called marginal cloud. The edge cloud is between the Internet of Things terminal and center cloud. It is the nerve center calculated on the edge.
Under the development of edge computing, through the widely distributed edge cloud, the calculation and intelligence of the user terminal can be moved to the edge, so that the calculation pressure of the terminal can be released, making it lower power consumption and lightweight, accelerating the prosperity of VR and other applications.
也得益于边缘计算等新技术的进一步发展,6G时代很多终端产品都会被重塑或者淘汰,随着6G技术问世的时候,扩展现实（XR）将取代手机,XR是虚拟现实（VR）、 The collective term of the reality (AR) and hybrid reality (MR) technology.
In the 5G era, technologies such as VR (virtual reality), AR (augmented reality) and MR (hybrid reality) have further developed, and in the 6G era, they will become more mature. New devices of different types will replace smartphones into human work to become human work. The main tool of entertainment.
Although the 6G white paper published by the University of Oru is just a prospect of the future, in fact, many countries have made a certain prediction of 6G. Thinking of the leaders of the 6G era in advance, it has become the leader of the global economy in the 6G era. Essence
For example, Japan NTT DoComo should have a clear plan for the development of 6G and has begun to implement. It regards 6G as a evolutionary version of 5G, that is, further improve the transmission rate and information capacity, and expand the network coverage. They have paid attention to the energy consumption problem of 6G big data processing, and look at low energy consumption and low -cost applications.
The University of Wudaul, Germany and Germany, came up with a very specific Tahez communication technology. Researchers have built a complete signal receiving system based on SIGE materials, which can achieve a 260GHz band of 1 meter distance. However, after calculation, if the lens antenna with a diameter of 6.5 cm is used, the communication distance can reach 100 meters.
Huawei believes that the 6G era will exceed the “Internet of Things” in the 5G era and realize the “Internet of Everything (IOE), that is, the entire humanistic society and the external physical world are closely connected. Therefore, 6G data is not a big data one by one. It is likely that countless small data is remitted into big data.
Huawei proposes that in terms of communication dimensions, in addition to higher rates and wider spectrum, 6G should expand to sea, land, air and even underwater space. In terms of hardware, the role of antenna is also more important. As the frequency of communication increases, the antenna will become smaller and smaller, and may even have its own antenna in each chip. This requires higher and higher materials, and higher requirements for materials and processing accuracy have been put forward. In terms of software, artificial intelligence will play an important role in 6G communication. In addition, Huawei even imagined to launch more than 10,000 small low -track satellites to achieve the idea of covering 6G communication around the world, and estimated the cost -9.9 billion US dollars. Huawei also plans to build a wireless communication network that can accommodate the 1Tbps transmission rate in 2030.
However, no matter what kind of 6G solutions proposed by various countries, they are focused on the wide spectrum, high speed, ultra -low latency, ultra -long distance, ultra -low power consumption, and AI -based application direction. The future development trend will definitely focus on these aspects.
Many times, the development of technology often exceeds our expectations. Can we catch up with the pace of the times and obtain the fruits of the times? It determines whether we can successfully seize the wind of the times. Do you expect 6G?
