DTECH 2026 Takeaways: Private LTE Edges Forward in Hybrid Utility Networks

DTECH 2026 in San Diego confirmed just how much the utility connectivity ecosystem has matured. For the Sequans team, being there felt less like discovering new territory and more like engaging with a community we know well—one that is evolving steadily while staying true to its mission. Utilities are part of a nation’s critical backbone: without reliable power, modern society—from hospitals and transportation to industry, data centers and homes—cannot function for long. What stood out this year was how carefully the sector is embracing new tools—private and hybrid cellular networks, stronger security practices, and emerging AI use cases—to improve reliability and modernization without losing sight of its responsibilities.

AI was more visible this year, but not as a hype cycle. It appeared as a practical enabler: in cloud platforms orchestrating fleets of assets and increasingly at the edge, where local intelligence can detect anomalies, optimize operations, and reduce truck rolls. For utilities managing millions of endpoints and complex distribution networks, this approach is intuitive. AI helps sift through massive data streams, surface what matters most, and support faster, better-informed decisions. Still, AI is only one piece of a broader puzzle that includes connectivity choices, security foundations, and long-term migration paths from LTE to 5G.

Hybrid public + private connectivity takes shape

A key takeaway from conversations was how nuanced connectivity strategies have become. Private LTE continues to attract interest, particularly as spectrum options such as Anterix band 106 and Black and Veatch band 26 become better understood and ecosystem-ready. Utilities recognize the value of control, predictable performance, and security that private networks can deliver for critical assets and defined geographies.

At the same time, few see private networks as a universal solution. Hybrid public-plus-private models are gaining traction as a pragmatic middle ground. Larger utilities may invest in private infrastructure for high-criticality operations while relying on public networks for broad coverage and faster rollout. Smaller utilities, often unable to justify full private deployments, are leveraging public cellular today while keeping the option open for targeted private use later.

This hybrid thinking is closely tied to future-proofing. A stable private LTE layer can support long device lifecycles, even as public networks evolve toward 5G. That stability, combined with public-network flexibility, allows utilities to adopt new capabilities on their own timelines—aligned with operational needs rather than forced technology shifts.

Security and trusted supply chains

Security discussions have moved well beyond checklists. Conversations increasingly focused on supply-chain trust: who designs the silicon, where products are manufactured, how firmware is updated, and how long vendors commit to supporting devices in the field. For utilities deploying assets that may remain operational for 10–20 years, this is foundational, not theoretical.

This reality is driving demand for transparent partners with clear IP ownership, secure manufacturing processes, and credible long-term roadmaps. Utilities want assurance that connectivity platforms will remain secure, supported, and compliant as regulations tighten and threats evolve. It reflects the sector’s conservative DNA: innovation is welcome, but only when the foundations are proven and durable.

Building on this, we have spent the past few years formalizing a practical playbook for secure, compliant cellular IoT: from our blog on engineering IoT security, focused on how to make “secure‑by‑design” tangible for product teams, to our white papers mapping concrete IoT threats and defenses to RED DA requirements, and detailing the security features and lifecycle controls available in today’s modules. Together, these resources are what we use to guide utilities and device vendors as they turn high‑level security and supply-chain expectations into architectures, design choices, and certification plans that can stand up over 10–20 years in the field.

How Sequans supports this transition

In this evolving landscape, Sequans positions its Monarch and Calliope families as enablers of both today’s LTE deployments and tomorrow’s 5G-ready architectures. Our chipsets and modules operate across public and private networks, giving utilities flexibility to choose the right connectivity mix at each stage of their journey. By supporting LTE-M, NB-IoT and LTE Cat 1bis today while providing a clear path toward 5G NR, we help customers design once and deploy with confidence over long lifecycles.

Our perspective is shaped by projects in the U.S. and globally. While regulatory frameworks and spectrum allocations differ, the underlying challenges are consistent: extending field visibility, enabling smarter automation, and strengthening resilience against physical and cyber risks. By combining cellular IoT expertise, secure supply chains, and a strong partner ecosystem, Sequans aims to support utilities worldwide as they build more connected, intelligent, and future-proof networks.
