o2-Telefónica's SPINE: Building AI-native mobile networks for Europe
o2-Telefónica is leading a German research and industry consortium to pitch SPINE (Sovereign Platform for Intelligent Network Evolution) for European funding. The goal: turn mobile networks into an AI-driven infrastructure that serves real workloads like connected mobility, telemedicine, XR, public safety, and modern manufacturing.
The planned project value is 43 million euros. The focus is clear-reliable performance, low latency, and energy efficiency, delivered with European standards and data sovereignty baked in.
What SPINE is actually building
SPINE targets an AI-first network lifecycle: define requirements, design and configure, then operate with continuous feedback. It blends telecom networks with modern AI models, operational data, and automated control loops to keep services fast, predictable, and efficient-at scale.
Funding and why it matters
The proposal goes through the EU's Important Project of Common European Interest for Artificial Intelligence (IPCEI AI). It exists to back strategic AI projects that are too large or risky for any single company or country to fund alone-supporting digital sovereignty for the long term.
Who's in the consortium
Research: Fraunhofer FOKUS, Fraunhofer HHI, Fraunhofer IIS, and TU Darmstadt (in talks with TU Delft). Industry and technology: Nokia, Capgemini, Sopra Steria, LTIMindtree, plus startups AiVader and Highstreet Technologies.
Leadership statements highlight the same point: strong mobile networks are foundational for practical AI-close to compute, secure by design, and operated under European standards and data sovereignty.
Why networks must change for AI
Next-gen AI use cases need higher throughput, tighter latency budgets, and far more automation. Data volumes keep growing, traffic patterns are less predictable, and the energy footprint matters. Existing architectures struggle under those conditions without edge compute, distributed intelligence, and closed-loop operations.
Spain as a reference point
Telefónica in Spain is already deploying a nationwide edge infrastructure under an EU IPCEI-CIS project. Ten edge nodes are live today, expanding to 17 by 2026. The aim is straightforward: low-latency AI apps, stronger data control, and open, interoperable architectures.
The plan: four work phases
- Requirements analysis: Quantify capacity, latency, reliability, and energy metrics for future AI workloads.
- Distributed network intelligence: Design AI-assisted concepts for planning, control, and assurance across RAN, transport, and core.
- Lifecycle automation: Make design, interaction, and operations more automated and resource-aware, end to end.
- Data-model loop: Build models from mobility and traffic data with strict security and privacy, aligned to European standards.
What this means for developers and network engineers
- Go edge-first for inference: Expect inference near the RAN or metro edge. Containerize services, keep images small, and plan for constrained nodes.
- Latency budgets as SLOs: Set hard SLOs for E2E latency, jitter, and packet loss. Measure per segment (device, RAN, transport, edge, service) and enforce with admission control.
- Model efficiency matters: Use pruning, distillation, and INT8/FP16 quantization. Favor streaming-friendly architectures and event-driven pipelines.
- MLOps at the edge: Automate feature stores, drift detection, and rollbacks. Push small, frequent updates with GitOps and staged canaries.
- Observability and energy: Instrument with OpenTelemetry and expose energy metrics per slice/service. Tie scaling decisions to both SLOs and power budgets.
- Security and data governance: Minimize PII, prefer federated learning where it fits, and use TEEs/TPMs for key workloads. Keep audit trails and encryption standards aligned with EU guidance.
- Standards and interop: Expect ETSI MEC, O-RAN concepts, APIs, and open interfaces to matter. Design for portability across locations and vendors.
Constraints and the real bottleneck
Forty-three million euros is a start, not a rollout budget. Rural coverage, backhaul, and mid-mile capacity still need heavy investment. AI can optimize what exists, but it can't pass packets over a link that isn't there.
If you prioritize by user experience data-where calls drop, where XR stutters, where telemedicine buffers-you'll find the work that moves the needle. Build where demand and latency sensitivity meet, then automate the rest.
Use cases SPINE is targeting
- Autonomous and connected mobility
- Smart power grids and industrial production lines
- Telemedicine and public security applications
- XR services that require tight latency control
