Samsung Research has published a 6G white paper, outlining the company's vision on the next generation of mobile technology. The paper describes Samsung's view of how 6G may be developed into the next mobile technology standard, with mass adoption expected from around 2030. The research group expects 6G to enable novel applications such as immersive extended reality, based on significant performance improvements over 5G. New technology concepts that may be incorporated into 6G include native AI and the use of extremely high radio frequencies.

Samsung expects 6G commercialisation from 2028 and mass adoption from around 2030. The company's research unit views 6G as the technology platform enabling innovative services including immersive extended reality (XR), high-fidelity mobile holograms and digital replicas. The paper formulates three requirements for the technology, as well as a number of technology concepts that could be integrated with 6G.

The next generation of mobile technology has been in development for a few years. It was mentioned as early as 2017 by DARPA, the US Department of Defense's research organisation. The ITU started a post-5G research project in 2018 (Network 2030) and the University of Oulu (Finland) was first to host a 6G conference in 2019. China, Japan, the US and the EU have each already kicked off 6G projects.

Samsung established its Advanced Communications Research Centre for 6G in 2019. Its latest white paper follows a similar publication from NTT in January. While the companies are starting work on 6G, the new technology is still several years away. 5G is still in full development, with Release 16 just finalised and Release 17 expected by the end of 2021 at the earliest.

Samsung's requirements for 6G are about performance (similar to the way 5G was conceived), architecture and trustworthiness.

- Performance: Samsung raises the bar on 5G on a number of levels, including spectral efficiency (targeting a 2x improvement on 5G's ultimate goals), energy efficiency (also 2x), connection density (10x), peak data rate (50x to a maximum of 1,000 Gbps) and air latency (targeting a 90% reduction from 5G's goal of 1 millisecond to 100 microseconds).
- Architecture. Here 6G is expected to resolve issues arising from the limited computing capabilities of mobile devices, to implement AI from the initial phase of technology development and to enable a flexible integration of new network entities.
- Trustworthiness. From this perspective 6G needs to address security and privacy issues arising from the widespread use of user data and AI technology.

As much as 5G is being enhanced with a number of technology concepts (massive MIMO, network slicing, mobile edge computing, dynamic spectrum sharing), Samsung proposes a new set of concepts that may find their way into the 6G standard in one way or another. These include:

- The use of Terahertz spectrum.
- Novel antenna technologies to enhance coverage of high-frequency band signals.
- Advanced duplex technologies.
- The evolution of network topology.
- Spectrum sharing to increase the efficiency of frequency utilization.
- The use of AI in wireless communication.

Te verwachten is dat er met de hogere frequenties van 6G nog meer gezondheidsproblemen te verwachten zijn dan met 5G. Ergens moet het wat gezondheid betreft toch helemaal mislopen.
