6G The development of network is accelerating , A new Finnish consortium hopes to accelerate the development of next-generation radio technology , A Japanese American alliance is also seeking to lead the standardization of technology that is crucial for unmanned applications .

6G The development and deployment of the mobile industry is considered “ Trillion dollar opportunity ”, And technology leadership is increasingly becoming a political priority for many governments around the world .

Although it is predicted now 6G It's too early to know what the final form of the standard will take and what technologies it will include , But for its capabilities and operators 、 There are some reasonable assumptions about the challenges faced by manufacturers and researchers .

6G radio

natural ,6G The network will be at speed 、 Great progress has been made in capacity and low latency , At the same time, they are expected to be more intelligent and reliable . This will provide excellent mobile broadband , It also supports advanced services , For example, real immersive extended reality (XR)、 High fidelity mobile holograms and digital twins .

The core of these applications will be 6G Ability to make up for current limitations —— For example, the limited processing capacity of mobile devices —— And integrating intelligence into the network .

If the most ambitious goals are achieved , that 6G The capacity of will be 5G Of 100 times , Every square kilometer will be able to support 1000 Wan Tai equipment .

The signal will extend above the surface 10,000 rice , Realize the sky 、 Space and underwater “3D Cover ”. All these functions will allow intelligent sensing 、 location 、 Edge computing and HD imaging .

However , One of the biggest challenges may be spectrum ,6G Use higher frequencies to maximize capacity gain , Include 1THz and sub-THz level . Radio technology and spectrum are the focus of new projects in Finland .

The country is in the radio access network (RAN) The development of technology has a long history , And hope that with the industry from 5G towards 6G Change and maintain this tradition .RF Sampo The project consists of nine companies and three research institutions , Including Nokia 、Bittium And the University of olu .

6G Standardization

“ Finland has a long tradition in radio technology , This is the core of wireless system ,” NOKIA Saila Tammelin say , He is the industrial director of the project .“RF Sampo It aims to strengthen Finland's competitiveness in radio technology , At the same time, it surpasses industry 5G And move towards 6G.

“RF Sampo Including wireless electronic system 、 Development of components and algorithms . It also solves the development of working methods that can put innovation into use faster , for example , Through more effective simulation and modeling methods . Solving the challenges of increasingly complex wireless systems requires close R & D cooperation between companies and research institutions —— To expand and update Finland's knowledge base and innovation capacity ,”

RF Sampo Will focus on making 6G Radio technology is as efficient as possible , Take advantage of the power of new frequency bands and antenna technology , And create can reduce 6G Complex design . say concretely , It will study 5G and 6G New RF Technology , Including antenna structure 、 The integrated circuit 、 New RF architecture and Algorithm .

in addition , Japan and the United States will cooperate to commercialize chip level atomic clock technology , This is similar to GPS The way of real-time control and positioning of driverless vehicles and unmanned aerial vehicles is very important . It is hoped that this technology will be used in 2025 Developed years ago , Its efforts will include a range of industries , Including cars 、 Mobile and watch industry .

In view of the fact that our country will 6G The development of mobile connectivity has a greater impact than previous generations , Japan and the United States also hope to maintain a leading position in standardization .
