2026 marks a critical turning point for 5G RAN strategy. After years of trials, proofs of concept, and shifting industry narratives, the conversation has moved beyond abstract debates about disaggregation to practical, high‑stakes decisions shaped by 5G Standalone rollout, expiring long‑term supply contracts, and new spectrum across DACH and CEE.

For CTOs and VPs of Technology, this is not a technology debate — it is a capital allocation decision with multi‑year consequences for network performance, operational costs, and competitive advantage. And the industry focus has shifted: AI‑RAN is now the strategic priority, while earlier expectations of widespread multivendor Open RAN have given way to more pragmatic, risk‑managed approaches.

Why RAN Strategy Is a 2026 Decision

Three overlapping factors make this the year for decisive action:

• 5G Standalone is no longer optional — SA deployment is accelerating across Europe, as outlined in Network X’s Mobile Networks theme. Austria, Switzerland and Spain lead adoption; industry analysis confirms Europe’s share of 5G SA connections grew significantly between late 2024 and late 2025, with major markets recording double‑digit percentage point increases. To deliver on network slicing, ultra‑low latency and efficiency, the RAN itself must evolve beyond legacy hardware‑bound architectures.
• Contract cycles force renewal — Many 10‑year RAN agreements signed at the start of 5G rollout are up for renewal or renegotiation in 2026‑2027. Deferring decisions today locks in architecture and vendor relationships for another multi‑year cycle, shaping infrastructure economics through the next decade.
• Spectrum and modernisation create natural decision points — New mid‑band and C‑band spectrum secured in recent auctions is now being deployed. The architecture chosen now defines flexibility, integration complexity, and the ability to adopt AI‑driven optimisation without costly forklift upgrades.

The AI-RAN Reality Check

The industry conversation has shifted: where 2023–2025 was dominated by Open RAN debates, 2026 centres on AI‑native RAN

• Market reality: Industry analysis shows multivendor disaggregated RAN uptake has been slower than forecast, with interoperability and integration costs remaining key barriers; established vendors have consolidated core supply positions, while open interfaces are now being embedded into next‑generation systems rather than deployed as standalone replacements.
• AI‑RAN definition: As set out in your technology transition framework, AI‑RAN covers three practical areas: using AI to optimise radio performance and energy use; orchestrating AI and RAN workloads on shared infrastructure; and hosting edge AI capabilities directly on the network — all focused on delivering measurable efficiency and performance gains.
• Early progress: Operators and vendors are running live trials focused on spectral efficiency, throughput improvement and automation — but all confirm that business case and scalability remain under review, with no universal deployment roadmap yet established.
• Core priority for operators: RAN choices made in 2026 must prioritise AI‑readiness — cloud‑native, software‑upgradeable infrastructure that can absorb AI‑driven capabilities without full hardware replacement — rather than treating AI‑RAN as a separate future project.

What Operators Are Actually Prioritising

Cutting through the noise, European operators are not choosing “all‑or‑nothing” — they are pursuing three clear, practical priorities fully aligned with your Messaging House:

• Performance parity is non‑negotiable — No operator will trade reliability or service quality for architecture flexibility. All change must match or exceed existing SLAs before scale‑up.
• Pragmatic, phased evolution — Leaders including Vodafone and Deutsche Telekom are adopting hybrid models: starting in lower‑risk areas, building internal capability, and scaling only when proven.
• Diversification is strategic — The goal is not short‑term cost cuts alone, but reducing supply chain risk, avoiding lock‑in, and building foundations for 5G‑Advanced and 6G — exactly as outlined in your Mobile Networks theme.

Where Network X 2026 Fits

Making these decisions requires more than vendor presentations and data sheets. It requires peer‑to‑peer insight, real deployment lessons, and regional perspective.

That is exactly the value of Network X 2026, taking place 13–15 October at VIECON, Vienna.
