85G Evolution Towards a Super‐connected World

8.1 Overview

Mobile communication technologies have been evolving for many years, with each generation transforming the way we experience new services. The smartphone market has expanded significantly in recent years and is expected to grow further in the years to come; therefore, the network must continue to evolve to keep pace with users' demands, even beyond the common usage connectivity. The envisioned market space for the next generation technology is being driven by requirements to enhance mobile broadband connectivity, reach a massive range of machine‐type communication (MTC), and target services with ultra‐reliable and low‐latency (URLLC) communications. To deliver these requirements, 5G must be designed with scalability and diversity across many components from the spectrum, core network, radio access, and devices.

8.2 Introduction

The envisioned market space for 5G technology involves a design that has the capability to unify the system needed by various use cases. New use cases keep evolving according to the need for higher peak data rates, reduced end‐to‐end service latency, and increased network capacity in terms of user traffic and density. In addition, use cases suitable for the commercial 4G LTE network capabilities keep appearing beyond today's usage, and potentially even beyond what the network and devices were designed for.

A wide range of new applications and use cases requires advanced connectivity capabilities that ...
