Sterile, serialized, deterministic: Private 5G is the foundation of pharma’s reshoring boom

More than $170 billion is flowing into new pharmaceutical manufacturing facilities across the US. Driven by supply chain disruptions, national security priorities and changing trade policies, this reshoring effort represents one of the largest industrial investment waves in recent history.

Yet one of the most important decisions regarding these facilities isn’t receiving much attention.

Long before production begins, pharmaceutical manufacturers must decide how every system, machine and process inside the plant will connect. That decision will determine how the facility operates for decades. Once an aseptic production line has been validated, changing its connectivity infrastructure means revalidation — a costly and disruptive undertaking.

For pharmaceutical CIOs and plant engineering leaders, wireless connectivity has therefore become one of the most consequential infrastructure decisions they will make — not because it’s the biggest line item in the budget but because it underpins automation, compliance, data integrity and operational resilience.

As these next-generation facilities move from blueprint to production, the opportunity to get that decision right is narrowing quickly. Private 5G is uniquely positioned to meet the deterministic, secure and compliant connectivity requirements of these environments.

The cleanroom: The toughest wireless environment you’ll ever encounter

Few environments place greater demands on wireless connectivity than a pharmaceutical manufacturing facility. And few have higher consequences when that connectivity fails.

Aseptic manufacturing suites are filled with stainless steel, isolators and other equipment that reflect and scatter radio signals in ways that demand careful network design. At the same time, contamination-control requirements also make live troubleshooting of wireless infrastructure difficult. A coverage gap that would be a minor nuisance in a corporate office can become a validation issue inside a Good Manufacturing Practice (GMP) facility — referring to the system that ensures products are safely and consistently produced at high quality standards. And a validation issue can quickly become a regulatory concern.

The performance requirements are equally unforgiving. Continuous bioprocess control, sterile filling lines and high-speed packaging operations all depend on connectivity that remains predictable under all operating conditions. A dropped network handoff can half production, jeopardize a batch worth millions of dollars and trigger a regulatory investigation.

Serialization adds another layer of complexity. The US Drug Supply Chain Security Act requires item-level traceability for prescription drugs, meaning every saleable package must be uniquely identified and traceable throughout the supply chain. For manufacturers running packaging lines that process thousands of units per minute, this demands fast, reliable connectivity. It is not an environment where Wi-Fi, with its inherent variability under heavy loads, can reliably support operations.

Data integrity and connectivity right from the start

Data integrity underpins all of it. GMP and the US Food and Drug Administration’s 21 CFR Part 11 regulations require tamper-evident, traceable equipment telemetry with a complete audit trail. The network therefore becomes part of the compliance environment.

The challenge starts even before the facility is built. Wireless architecture typically has to be finalized before cleanroom construction begins. Once production systems have been validated, changing the underlying connectivity infrastructure becomes expensive, disruptive and time-consuming. With many new facilities moving from design to construction on compressed, tariff-driven schedules, the opportunity to make the right decision is closing quickly.

Building the validated, deterministic plant

NTT DATA’s approach is grounded in experience gained in regulated industrial environments. Private 5G should be treated as proven process infrastructure that is engineered and documented to the same standard as clean utilities and heating, ventilation and air conditioning (HVAC). It should not be treated as traditional enterprise IT extended to the plant floor.

Two initiatives define the architecture we bring to pharmaceutical manufacturing.

1. A single deterministic connectivity fabric

When you replace stitched-together Wi-Fi access points with campus-wide private 5G, your facility’s process control systems, connected workers, autonomous mobile robots, vision inspection and environmental IoT can operate on one governed network.

Private 5G delivers deterministic sub-30 millisecond latency, seamless handoffs and SIM-based device identity. Serialization cameras and material transport robots can operate continuously without losing connectivity. Coverage is engineered and documented, aligning with validation requirements.

The result is fewer production interruptions, improved serialization performance and a network that can be fully incorporated into validation documentation.

2. On-premises edge AI for yield, quality and release

Pairing private 5G with on-premises edge computing creates a manufacturing intelligence platform well suited to pharmaceutical operations.

Real-time vision inspection identifies defects before they move downstream, while predictive maintenance continuously monitors chillers, HVAC systems and other critical equipment to detect developing issues.

At the same time, GMP-relevant process records, proprietary formulation data and manufacturing telemetry remain on-premises under the plant’s control with a complete audit trail. Sensitive intellectual property never leaves the facility.

The result is fewer defects, less scrapped product and a more resilient production schedule.

NTT DATA’s full-stack advantage for regulated industries

Many technology vendors will claim a role in the pharmaceutical connectivity conversation. Our differentiation is built on delivering results in environments that closely mirror the challenges that pharmaceutical manufacturers face today.

We deployed private 5G for Celanese Corporation, the global specialty materials and chemical company, in a demanding industrial environment spanning hazardous zones, batch chemistry processes and SAP-integrated manufacturing execution systems. This environment closely resembles a sterile pharmaceutical facility: regulated, process-critical and tightly integrated with enterprise systems.

With our fully managed edge AI platform — the industry’s first managed IT/OT convergence platform — we go beyond connectivity to enable vision inspection, environmental monitoring and batch analytics, bringing networking, edge computing and AI together as a fully governed, SLA-backed managed service.

Scale matters just as much. Reshoring involves building many facilities, often on tight timelines. For Cargill, the global food, agricultural and industrial leader, we deployed private 5G at 50 sites, demonstrating our ability to deliver consistent, auditable architecture across a large manufacturing footprint. Repeatability reduces deployment risk and speeds up standardization.

In addition, we were named a Leader in Everest Group’s 5G Engineering Services PEAK Matrix® Assessment 2025 report and in the 2026 Gartner® Magic Quadrant™ for 4G and 5G Private Mobile Network Services.

The foundation for the future of pharmaceutical manufacturing

The pharmaceutical industry has a rare opportunity to do more than bring manufacturing back to the US. It can build a new generation of facilities designed for automation and AI from the ground up.

The decisions being made today will define how these plants operate for decades. Choices about connectivity, automation and data architecture will influence productivity, compliance, quality and manufacturers’ ability to adapt as technologies and regulations evolve.

The reshoring boom is about far more than building new factories. It’s also about laying the digital foundation for the next era of pharmaceutical manufacturing — one that helps organizations operate with greater confidence and stay competitive long after construction is complete.

At NTT DATA, we assist you in making these decisions. By combining private 5G, edge AI and deep experience in regulated manufacturing environments, we help you create facilities that are designed for today’s requirements and tomorrow’s innovations.
