10.1 Summary

5G is not just another radio technology, (i.e. not just an evolution of long term evolution, LTE), providing more capacity and lower latency to the end consumer, rather it's design and architecture principles follow a revolutionary concept, as for the first time this new system allows building open networks with open interfaces where in principle any level of network control can be offered to the outside world. The network can even offer itself as a service to tenants. The system architecture is designed to use network function virtualization (NFV) and software defined networking (SDN) concepts natively and exploit these technologies. The 5G technical enablers allow cost‐efficient support of diverse use cases with very different demands for throughput, latency, reliability, security, as described in Chapter 8 for ultra‐reliable low latency communication (URLLC) and Chapter 9 for Internet of Things (IoT). This will provide new opportunities to mobile operators, industries and end consumers. It will help people in their daily life, at their work places and in emergency situations. It allows connecting factories, which helps increasing the level of automation in various industries, i.e. less interruption time when designing and manufacturing goods of any kind. Connecting machines, things, and people can make life easier but also safer. The steadily growing data ...
