6G White Paper on Connectivity for Remote Areas
6G Research Visions, No. 1
The white paper “Key Drivers and Research Challenges for 6G Ubiquitous Wireless Intelligence” is based on the views that 70 invited experts shared during a special workshop at the first 6G Wireless Summit in Finnish Lapland in March 2019. The publication focuses on the key drivers, research requirements, challenges and research questions towards 6G.
The publication presents a strong vision of ubiquitous wireless intelligence for 2030. Ubiquitousservices will follow users seamlessly, everywhere, and wireless connectivity will be part of critical infrastructure. Furthermore, intelligence will create context-aware smart services and applications for human and non-human users alike.
6G White Paper is divided to seven themes:
Societal and Business Drivers for 6G
Drivers from society, including the United Nations Sustainable Development Goals (UN SDGs), will shape 6G. The move towards a data sharing / data market economy will raise issues with data ownership and contractual policies that require special attention. The transition to ever higher frequencies with smaller radio ranges and the increasing role of indoor networks will boost network sharing in cities and indoor spaces, and – especially – drive the “local operator” paradigm. Stakeholder roles in 6G will change compared to the current mobile business ecosystem and new roles will emerge.
6G Use Cases and New Device Forms
Smart phones are likely to be replaced by pervasive XR experiences through lightweight glasses delivering unprecedented resolution, frame rates, and dynamic range. Telepresence will be made possible by high resolution imaging and sensing, wearable displays, mobile robots and drones, specialized processors, and next-generation wireless networks. Autonomous vehicles for ecologically sustainable transport and logistics are made possible by advances in wireless networks and in distributed artificial intelligence (AI) and sensing.
Radio Hardware Progress and Challenges
Extended spectrum towards THz enables merging communications and new applications, such as 3D imaging and sensing. New paradigms for transceiver architecture and computing will be needed to achieve 1 Tbps. There are opportunities for semiconductors, optics and new materials in THz applications. Increased complexity will introduce the need for open-source platforms to make the next generation hardware and software solutions happen.
Physical Layer and Wireless System
Artificial intelligence will play a major role both in link and system level solutions of 6G wireless networks. New grant-free access methods are critical for truly massive machine-type communication. Signal shaping is a way to achieve record-high spectral efficiency. The strongest security protection may be achieved at the physical layer. Backscatter communications using RF power for connectivity and computation may enable hyper-low-power communications. 6G wireless networks may shape the radio environment to their liking.
6G needs a network with embedded trust. 6G network should provide proper mitigation and protection from attacks. 6G will create data markets where privacy protection together with clear rules for the market will be key enablers. 6G needs an upgraded networking paradigm moving from best effort to differentiated service quality.
New Service Enablers
6G is not only about moving data: it will become a framework of services, including communication services. In 6G, all user-specific computation and intelligence may move to the edge cloud. Integration of sensing, imaging and highly accurate positioning capabilities with mobility opens a myriad of new applications in 6G. Trust and privacy are key prerequisites for a successful 6G service platform.
