5G Extreme Requirements: End to End Considerations

The aim of this paper is to highlight what implications and trade-offs related to the delivery of new 5G services are relevant for mobile network operators. Some of these new services, in fact, require extremely low latency and high reliability of the communication link, which have very little in common with the targets that the telecommunications industry has worked towards until today. The new 5G requirements, in fact, now call for a re-think on how the future network will have to be designed and optimised in order to enable the new services. The purpose of this document is to identify realistic end-to-end deployment configurations that can potentially deliver the 5G extreme services across their footprint and to highlight some of the key challenges that come into play in this context.
