This report builds on the findings of the Nordic-Baltic 5G Monitoring Tool (N-B 5G MT) project ‘Analytical Report’, which focused on mapping 5G activities in the Nordic-Baltic region and analysing their roll-out status. In this follow-up report, we delve deeper into actual 5G applications across different verticals (i.e. sectors), including healthcare, transportation/mobility, industry and media/broadcasting. The report identifies challenges in each sector, such as funding constraints in healthcare, technical hurdles in transportation, market immaturity in industry, and infrastructure investment needs in media, highlighting the complex landscape of 5G deployment. Key cross-cutting challenges include uncertain business cases due to lack of clear benefits and empirical validation, financial barriers from high deployment costs and insufficient early-stage funding, technical and infrastructural limitations, especially in rural areas, regulatory constraints including spectrum allocation and data privacy, security and privacy concerns necessitating a comprehensive approach for compliance, acceptability and usability issues that require simplifying 5G for broader adoption, and collaboration challenges highlighting the need for forums, dialogue sessions, and partnerships to facilitate idea exchange and project advancements. Overall, the report emphasizes the need for a systemic approach to addressing these challenges. This includes clarifying the business value of 5G; fostering ecosystems for collaboration; and ensuring that policy and regulatory frameworks support the innovative, equitable deployment of 5G technology. Overcoming these hurdles will require concerted efforts from all stakeholders, including governments, industry and the wider community. Only then will the transformative potential of 5G for society be fully realized.

“…If dynamic sharing technology is adopted, network resources can be borrowed between different shards, thus creating a different pattern from the situation of independent networks. In addition, as network slicing shares physical resources, it is also necessary to consider the negative impact on each other [54].…”

Under the auspice of further developing 5G mobile communication technology and integrating it with the latest advancements in the field of Industrial Internet-of-Things, this study conducts in-depth research and detailed analysis on the combination of 5G with industrial systems based on composite structures, communication network architectures, wireless application scenarios, and communication protocols. The status quo, development trend, and necessity of 5G mobile communication technology are explored and its potential in industrial applications is analyzed. Based on the current practical development level of 5G technology, by considering different requirements for bandwidth, real-time performance, and reliability in communication networks of industrial systems, this study proposes three feasible paths for the integration between 5G and industrial systems, including the method to use 5G in place of field buses. Finally, by introducing real-world cases, this study has successfully demonstrated the integration of 5G and industrial systems by extending 5G terminals as field bus gateways. This study provides valuable references for research and practice in related fields.

The research and innovation related to fifth-generation (5G) networks that has been carried out in recent years has decided on the fundamentals of the smart slice in radio access networks (RANs), as well as the autonomous fixed network operation. One of the most challenging objectives of beyond 5G (B5G) and sixth-generation (6G) networks is the deployment of mechanisms that enable smart end-to-end (e2e) network operation, which is required for the achievement of the stringent service requirements of the envisioned use cases to be supported in the short term. Therefore, smart actions, such as dynamic capacity allocation, flexible functional split, and dynamic slice management need to be performed in tight coordination with the autonomous capacity management of the fixed transport network infrastructure. Otherwise, the benefits of smart slice operation (i.e., cost and energy savings while ensuring per-slice service requirements) might be cancelled due to uncoordinated autonomous fixed network operation. Notably, the transport network in charge of supporting slices from the user equipment (UE) to the core expands across access and metro fixed networks. The required coordination needs to be performed while keeping the privacy of the radio and fixed network domains, which is important in multi-tenant scenarios where both network segments are managed by different operators. In this paper, we propose a novel approach that explores the concept of context-aware network operation, where the slice control anticipates the aggregated and anonymized information of the expected slice operation that is sent to the fixed network orchestrator in an asynchronous way. The context is then used as the input for the artificial intelligence (AI)-based models used by the fixed network control for the predictive capacity management of optical connections in support of RAN slices. This context-aware network operation aims at enabling accurate and reliable autonomous fixed network operation under extremely dynamic traffic originated by smart RAN operation. The exhaustive numerical results show that slice context availability improves the benchmarking fixed network predictive methods (90% reduction in prediction maximum error) remarkably in the foreseen B5G scenarios, for both access and metro segments and in heterogeneous service demand scenarios. Moreover, context-aware network operation enables robust and efficient operation of optical networks in support of dense RAN cells (>32 base stations per cell), while the benchmarking methods fail to guarantee different operational objectives.
