Until now, these digital services have been mainly provided by Internet players (i.e., platforms and content providers), while mobile network operators are providing connectivity to this Internet of services. However, when moving forward in the course of digitalization, social activities and business processes will be progressively transformed. Companies and public organizations will then become key players to implement and benefit from this transformation, and the future 6G requirements should therefore be driven by their pain points and use cases. This also implies a greater involvement of B2B verticals in the 6G standardization process, as outlined in the following chapters of this book.

      In the 6G era, innovative mobile network operators will reap benefits from several business models simultaneously: besides selling connectivity services to end‐users, telecommunication operators will provide the required connectivity resources to B2B players (including companies, cities, public authorities, etc.) to fulfill their own missions. Connectivity solutions will need to be flexible enough to adapt to more and more heterogeneous Quality of Service (QoS) requirements, along the lines of what 5G is offering with network slicing. We illustrate this point in the following sections by providing relevant KPIs for the described use cases in the B2B market. 6G should therefore be an opportunity for industry players to invent and design new devices and networking strategies to support their own digital transformation needs of processes and social activities.

2.3 Use Cases for the B2B Market

This section reviews the characteristics and requirements of envisioned 6G use cases for the B2B market, as summarized in Table 2.1.

      2.3.1 Industry and Manufacturing

      Each production facility and industrial area is a different use case with particular requirements. Industrial deployments, particularly in manufacturing, tend to have equipment and machinery with life cycles that extend over a decade. Therefore, the introduction and use of cellular networks for applications with stringent requirements is a long and gradual process that has started in dedicated deployments for a well‐defined set of application. Thus, the integration with existing equipment, wired solutions, and radio access technologies (RATs) will still be required for many years into the future to ensure backward compatibility and improve overall performance.

      As front‐runners expand the applications relying on cellular networks, more complex deployments and applications will emerge. For example: dynamic deployments with URLLC requirements for exploration, mining activities, and wide area monitoring of pipelines, electric grids, and other critical infrastructures and the need for robots to perform cooperative maneuvers that require high precision and coordination. Moreover, for the factory cases with extreme performance requirements, it will be crucial СКАЧАТЬ
