White paper on business of 6G

6G vision and the industry consensus of underlying technology enablers have come a long way and will shape the new access, networking, and service domains in future mobile communications. These novel features promise countless opportunities for service innovation and business efficiencies, creating an unprecedented impact on multiple vertical sectors. 6G will connect worlds in novel and innovative ways — the physical and digital worlds will be deeply intertwined in real time, human biological systems will be seamlessly coupled, and at the same time, there will be a new human sensory and cognitive dimension across the scenarios of the 6G experience. Key technology-enabling themes to be explored will include the pervasive leverage of machine learning and artificial intelligence across architectural domains to flexibly define the air interface, as well as service management and orchestration in the 6G “network of networks” topology and platform ecosystem. Terahertz (THz) research is one of the prominent topics, utilizing spectral bands of above 100 GHz for both communications and sensing purposes, thereby enabling connectivity data speeds in the Terabit/s range. We foresee millions of sub-networks and devices becoming the network in conjunction with extreme performance attributes in terms of both sub-millisecond latency, high reliability and time-sensitive determinism, and advanced ways to assure security, privacy, and trust. In line with 6G vision and technology enablers, developing products, services, and vertical applications for the future digitized society in the 6G era requires a multidisciplinary approach and a redefinition of how we create, deliver, and consume network resources, data, and services for both communications and sensing purposes. This development will change and disrupt the traditional business models and ecosystem roles of digital service providers, as well as open the market for key stakeholders in the 6G era like digital service operators, cloud operators, and resource brokers. ...
