Industry 4.0 is all about the digital transformation of the physical infrastructure we use to sustainably extract resources, move them to market, manufacture, power, operate and service all aspects of our technological world, including the management of our cities and the well-being of our citizens. A key element in the implementation of Industry 4.0 solutions is the next-generation of network connectivity, 4.9G/LTE today, and 5G, in the future. Current private/enterprise connectivity including CAT cabling and IT-based wireless systems, such as Wi-Fi, will prove insufficient. These systems will need to be supplemented or even fully replaced by more robust, reliable and secure wireless systems. In this paper, we look at these industrial-grade wireless networks and how they will contribute to the realisation of Industry 4.0 applications.
