Siemens’ Private 5G Expansion Shows the Market Is Maturing—Sovereign Partnership Shows Where It Can Go Next

Siemens has been making significant strides in private 5G recently, with a wave of announcements spanning geographic expansion, new partnerships, and a push into sovereign infrastructure. The company has expanded its industrial-grade private 5G infrastructure to 15 countries across Europe and the Americas, adding Belgium, Canada, Finland, France, Norway, Poland, and the United Kingdom, with U.S. availability planned for summer 2026 via a dedicated Citizens Broadband Radio Service (CBRS)-band radio unit. The solution operates on licensed spectrum to deliver deterministic, interference-free connectivity for business-critical applications, and integrates with existing Information Technology (IT) and Operational Technology (OT) systems as part of the Siemens Xcelerator portfolio.

Siemens has also enhanced its 5G routers with edge runtime capabilities, allowing applications to run directly on the device, eliminating the need for additional hardware and enabling real-time, Artificial Intelligence (AI)-ready data processing on the shop floor. On the partnership front, Siemens and Schwarz Digits (the IT and digital arm of the Schwarz Group) announced a strategic collaboration at Hannover Messe on April 23, 2026 to deliver private 5G campus networks for critical infrastructure and security authorities, targeting both internal and national defense use cases.

There are two elements to these announcements: First, the geographical extension shows what ABI Research has been saying for years: vertical-specific players like Siemens are in a unique position to create an appealing value proposition for Private 5G. They know the pain points and workflows of (potentially) implementing industrial enterprise better than anyone else—especially the horizontally-organized telco vendors. Expanding to other markets with a strong industrial base is the next logical step and a clear testament to this refined Private 5G value proposition.

Arguably more interesting is the partnership between Schwarz Digits and Siemens on Private 5G for sovereign capabilities, as this has the potential to expand the Private 5G value proposition in a timely fashion. The two companies combine local 5G campus solutions with a European cloud infrastructure, explicitly avoiding dependence on non-European providers. For particularly sensitive deployments, the network is designed for air-gapped operation, meaning the local 5G network functions in complete isolation from the public Internet or external networks, with hardware-based Subscriber Identity Module (SIM) card access control for precise device authentication. Rather than relying on components from global suppliers, Schwarz Digits and Siemens have built a predominantly German value chain, with Siemens' hardware manufactured in Germany and all software and cloud components developed domestically.

This partnership comes at a time when enterprises put increased focus on technology sovereignty and digital resilience. Recent geopolitical tensions and macroeconomic tensions mean that sovereignty has now become a real-life engineering requirement. While regulatory frameworks like the NIS2 Directive, Digital Operational Resilience Act (DORA), and Cyber Resilience Act (CRA) are now making sovereign architectures legally necessary. Aside from public safety and defense use cases, sovereignty continues to be an interesting debate for several IT (and even some OT) industries as well. The fear of extraterritorial interventions into enterprise data storage and AI models has become a more concrete concern as a result of increased geopolitical tensions.

There is an interesting synergy to explore between Private 5G and sovereign cloud offerings. The present partnership between Schwarz Digits and Siemens seems very focused on a select group of use cases in the public safety/defense sector. This could become an interesting value proposition for other verticals and pave the way for Private 5G into more of the IT-dominated verticals (particularly heavily regulated industries like financial services or healthcare), where Siemens’ standing is not as overwhelmingly strong as in industrial environments. When targeting the private enterprise sector, any vendor should understand, however, that full sovereignty is not the panacea that would solve all enterprises’ worries about business continuity and resilient supply chain; quite the contrary, with recent events in the Middle East laying bare how a fully air-gapped sovereign solution can even hinder business continuity. It has taken AWS several weeks to get enterprises’ data and workflows back on track after one of its sovereign data centers in the region was attacked.

Consequently, any connectivity offering for a sovereign technology solution (that wants to be successful not only in the public, but also the private enterprise space) will have to strike a fine balance between sovereignty requirements and business continuity guarantees. To ensure maintaining their Private 5G leadership position as the market moves closer toward mission-critical use cases and highly regulated industries, telco vendors like Nokia and Ericsson should watch this partnership closely and develop a durable strategy to keep up.

• Identify the Right Partner for Business Resilience Solutions: Network infrastructure vendors should be actively identifying enterprises in each target vertical that have built genuine sovereign infrastructure capability internally and are exploring joint Go-to-Market (GTM) models. The vendor provides the network stack and certification pedigree, the partner provides peer-level commercial credibility and regulatory fluency. In IT-dominated verticals—financial services, healthcare, retail—neither vendor currently has the commercial operating credibility that makes it a natural peer to a Chief Information and Security Officer (CISO) or Chief Information Officer (CIO). The right partner fills that gap. Selection criteria should prioritize operational authenticity over partner size. Given the regulatory difference of geographical markets, each region (or even country) will likely have to be served with a different partner.
• Define a Clear Vertical-Specific GTM Strategy: While enterprises prefer existing and proven digitization partners, this is even stronger for highly-critical use cases that require some degree of sovereignty. A financial institution facing DORA obligations is not running an open tender for connectivity technology; it is extending a relationship with an incumbent it already trusts to handle sensitive infrastructure. A hospital network evaluating clinical data containment is not starting from the network layer up. In both cases, the telco vendor is not the natural entry point, and attempting to lead the conversation from a connectivity starting position means competing on unfamiliar ground against partners that have spent years building exactly the kind of institutional trust that sovereign use cases demand. Ericsson and Nokia need to accept this structural reality and design their GTM strategy around it. Only this will allow vendors to identify the incumbent digitization partner in each target vertical, and position the network stack as the infrastructure layer behind a proposition that partner owns and leads.
• Define Clear Architectures That Combine Sovereignty with Business Continuity/Resilience Elements: Full sovereignty, pursued without geographic or architectural redundancy, can leave an enterprise less resilient and disrupt operations in times of geopolitical tensions. In any partnership, telco vendors should apply their experience designing networks that integrate private and public assets across multiple jurisdictions, while maintaining continuity across heterogeneous infrastructure. The opportunity is to translate that experience into a structured methodology for regulated enterprises. Map workloads against regulatory obligations, designing topologies that satisfy data residency requirements without creating single points of failure, and certifying the result.
