The advanced fifth-generation (5G) infrastructure, or International Mobile Telecommunications (IMT) for 2020 and beyond, defined as the ubiquitous ultrabroadband network supporting the Future Internet (FI), will be a revolution in the information and communication technology (ICT) field. 5G technologies will efficiently enable new secure, dependable, ultrareliable, and delay-critical services to everyone and everything, such as cognitive objects and cyber physical systems. Full immersive experience and anything as a service are the primary drivers for a global adoption and market uptake of new technology components. The network will become the nervous system of the true digital society, digital economy, and silver economy (longevity economy). To realize this vision, 5G capabilities will include a new flexible and efficient wireless interface, access schemes, and other enabling wireless technologies, as well as a new plastic network architecture, supporting multitenant business models (providing support of different network designs for different customer segments or verticals), and using different virtual network slices (tailored system architectures) instantiated over a software-defined or single physical infrastructure.
