Recently, the University of Oulu in Finland released the world's first 6G network white paper, "Key Drivers and Research Challenges of 6G Wireless Ubiquitous," which analyzes the driving factors, research needs, challenges, and problems of 6G networks from seven aspects.
The white paper points out that regarding the differences between 5G networks and 6G networks, the performance indicators of 6G networks will increase by 10 to 100 times compared to 5G.
In addition, the white paper also gives several key indicators for measuring 6G network technology, including:
Peak transmission speed reaches 100Gbps-1Tbps, while 5G is only 10Gpbs;
The indoor positioning accuracy reaches 10 cm and outdoor is 1 meter, which is 10 times higher than 5G;
Communication delay is 0.1 milliseconds, which is one tenth of 5G;
The probability of interruption is less than one in a million, and it has super high reliability;
The density of connected devices reaches more than 100 per cubic meter, with ultra-high density;
Using terahertz (THz) frequency band communication, the network capacity is greatly improved.
In addition, in terms of coverage, 6G networks are no longer limited to the ground, but will seamlessly connect ground, satellite and airborne networks, and be deeply integrated with artificial intelligence and machine learning. Seeing, GPS system and cellular multi-point positioning have limited accuracy, and it is difficult to achieve accurate deployment of indoor items. 6G network is sufficient to achieve high-precision positioning of IoT devices.
Compared to 5G, 6G is more inclusive and extensible, so 6G will not only be for traditional operators, but will also create new ecosystems outside of traditional operators.
For example, due to the introduction of increasingly high frequency bands and increasingly dense networks, local networks targeted at the market will become more common. These local networks will be deployed by different stakeholders, thereby driving the "local operator" model and creating new ones. The product.
The white paper states that the 6G network will accelerate the development of technologies such as display and sensor imaging equipment. At that time, mobile phones are likely to become glasses, and the virtual reality (VR), augmented reality (AR), and mixed reality (MR) will be combined into one through the 6G network Extended Reality (XR) service. Through the development of fast network and virtual reality technology, it can also be applied in the fields of distance education, remote office, advanced three-dimensional simulation and so on.
However, the white paper also emphasizes that there are currently many problems in 6G network technology. The most difficult to solve is the immature terahertz communication technology, which is not a small challenge for integrated electronics and new materials. In addition, the 6G network also needs to solve the technical problems from data collection to consumption.
