Which are the challenges of 5G in cross-border?admin
Europe is preparing a large-scale deployment of 5G cross-border corridors for Connected and Automated Mobility on European transport paths.
The benefits for future mobility are many, but what about the challenges to be faced?
- Cellular coverage and radio access aspects + Service and Session continuity aspects: A fundamental requirement is cellular radio coverage and sufficient capacity to meet minimum bandwidth and maximum latency constraints. Without careful radio planning at the border, cellular connectivity can be greatly impaired due to a high level of interference in areas where coverage from neighbouring MNOs overlap or may even not be available at all when coverage gaps are present.
- MNO collaboration and Data Plane Routing: Mobility Management (MM) across borders is especially challenging as the agreed upon QoS/QoE needs to be guaranteed for CCAM users.
- Data management and protection: Besides the technical aspects, the provisioning of CCAM services across borders also entails significant data management, security and privacy issues that need to be resolved with a realistic approach.
- Non-functional aspects and business enablers: There is a number of non-functional, business and regulatory challenges that will also have to be resolved to guarantee a smooth collaboration and inter-play between neighbouring MNOs at the borders, which are critical for the successful transition of the CCAM services from one country to the other.
