Digital Twins for Industry 4.0 in the 6G Era
share
Having the Fifth Generation (5G) mobile communication system recently rolled out in many countries, the wireless community is now setting its eyes on the next era of Sixth Generation (6G). Inheriting from 5G its focus on industrial use cases, 6G is envisaged to become the infrastructural backbone of future intelligent industry. Especially, a combination of 6G and the emerging technologies of Digital Twins (DT) will give impetus to the next evolution of Industry 4.0 (I4.0) systems. Here we provide a vision for the future 6G industrial DT ecosystem, which shall bridge the gaps between humans, machines, and the data infrastructure, and therewith enable numerous novel application scenarios. Subsequently, we explore the technical challenges that are brought by such ambitions, and identify the key enabling technologies that may help tackle down these issues.
