3.2. 5G use cases and the technology’s impact on our world The main innovation in 5G is that it is expected to enable a large number of connected devices such as data-collecting sensors, combined with its ability to navigate robotic devices from remote locations. This means that large numbers of data can be collected in the field, processed remotely (in nearby locations via the so called ‘edge computing’ or in faraway locations via the so called ‘cloud computing’), and then used extensively to impact the real world. This, in combination with advances in Artificial Intelligence (AI), can unleash a true technological revolution. It is sometimes also called Industry 4.0, but its reach will go far beyond the industry. “ 5G will enable a large number of connected data-collecting devices, along with robots empowered by such data processed by AI in the edge and cloud” Technically, we can split 5G use cases into the following categories: Fixed-Wireless Access (FWA). This is the so far economically most solid use case. Local 5G networks with multiple fibre-connected sites in each street would allow households, particularly in suburbs, to enjoy fibre-like speeds without costs and inconveniences of installing fibre into each property. FWA was the leading use case for the early 5G installations in the US. Consumer smartphones and other devices. Higher speed can bring more power and convenience to the consumer smartphones. It may allow, for example, very fast downloads of movies before boarding a plane. In the absence of variety of other devices, the mobile industry is likely to focus on 5G smartphones initially. Later on, 5G should empower new types of consumer devices such as virtual and augmented reality glasses. This could create fundamentally new products and experiences, although some of these technologies may still have to overcome certain challenges (picture quality, battery life, radiation safety etc). 18
