5G is not just another generation of mobile communications technology. 5G can be seen as "the network of networks" and it is going to have a profound impact on all human activities, the economy and the society. In fact, 5G can be seen as the digitalization catalyst for industries, as a variety of use cases will be either enhanced or created by the use of 5G. Immersive gaming, autonomous driving, remote robotic surgery and augmented reality support in maintenance and repair situations are just some of the use cases that will mostly benefit from the introduction of 5G. But what is the business potential of 5G? Ericsson, together with Arthur D. Little recently made a unique study in order to understand the industrial digitalization revenues for ICT players in 8 key industries. We have shared these findings with the IEEE 5G Summit's audience (Thessaloniki, July 11, 2017).
