The next IoT challenge: making connected products work at global scale

Connected products have entered a new phase. Scaling IoT globally now requires far more than connecting a device. Deutsche Telekom IoT sees this shift across industries, from logistics and healthcare to smart buildings and industrial automation.

Connecting a machine, container, medical device, meter or robot is no longer the biggest challenge. The harder question is whether that product will keep generating value when it leaves the lab, crosses borders, switches networks, ages in the field and becomes part of daily operations.

When a connected product fails to deliver critical data at the right moment, the impact goes far beyond a technical issue. It can affect service reliability, operational performance and customer trust.

This shift is reflected in Deutsche Telekom IoT’s “Smarter with IoT” approach: helping organizations move from isolated connected devices towards scalable, manageable IoT services that work reliably across markets and use cases.

From connected devices to connected operations

While many IoT programmes begin with successful pilot deployments, scaling those deployments internationally introduces a far more complex operational challenge. Organizations must then contend with network availability, roaming, persistent device communication, fleet management, data security, regulatory compliance, lifecycle costs and large-scale support requirements.

Simon Boyd, IoT expert at Deutsche Telekom IoT, sees this as the real test for connected-product strategies. “A pilot proves the concept. Scale proves whether the operating model works. Once products move across markets, networks and regulations, connectivity becomes part of the product itself,” he says.

That distinction matters. If a connected product is deployed globally, rented as a service, monitored remotely or used in a regulated environment, network access is no longer a background function. It becomes part of the product experience, service reliability and ultimately customer trust.

In practice, this means four requirements: global reach, security, flexibility and simplicity. Organizations need central visibility over devices, SIMs, data usage, security policies and connection status, as well as a managed IoT environment that reduces operational complexity rather than adding to it.

Why global products need global infrastructure

Global scale changes the role of connected infrastructure. A product that operates in one country can often be supported with local workarounds. A product that moves across networks, jurisdictions and operating environments needs a more resilient foundation. At that point, IoT becomes less about connecting individual devices and more about managing connected operations.

The business case is easy to see in logistics. Global logistics provider Dachser uses connected swap bodies across its European operations. Around 8,500 swap bodies are equipped with tracking modules that relay position data via LTE-M to the cloud, helping the company improve transparency, use cargo space more efficiently and optimise processes across its network.

The same logic applies in healthcare, where connected products can directly influence confidence in the care model. Medical technology company BIOTRONIK uses IoT to transmit data from connected pacemakers and defibrillators daily to more than 5,000 clinics and medical practices worldwide. The value is not just that the device is connected. It is that reliable data transmission becomes part of continuous care.

In the built environment, Northern Irish startup CreevX shows how IoT can turn a manual compliance process into an automated, data-driven service. Its devices monitor water temperatures, trigger automatic flushing where needed and send data to the cloud via Deutsche Telekom's mobile IoT network. Telekom's global IoT connectivity helps CreevX deploy across the UK, Ireland and Europe on a single tariff, without separate country contracts.

These examples point to the same conclusion: smart products do not scale through hardware alone. They scale through resilient infrastructure, manageable data flows, central control and an operating model that can support them over time.

Three questions scaling teams should ask before expanding IoT

1. Is connectivity designed into the product or added afterwards?
   If connectivity is treated as an add-on, complexity often emerges further down the line, particularly around provisioning, diagnostics, support and lifecycle management. For products operating at global scale, connectivity needs to be embedded into the product architecture from the outset.
2. Can the solution work across markets without creating excess complexity?
   Connected products often need to function in different countries, networks and regulatory environments. IT, operations and product teams therefore need clear visibility and control over devices, SIMs, data usage, security policies and connectivity status across the entire fleet.
3. Can the organization support the product once it becomes an ongoing service?
   Connected products fundamentally change the relationship between manufacturers and customers. Manufacturers may need to monitor performance, provide remote updates, detect faults, support customers and prove compliance long after the product has shipped. This requires platforms, processes and partners designed for continuous operation.

The new role of connected infrastructure

The next wave of IoT will not be defined by the number of connected devices alone. It will be defined by which organizations can make those devices work reliably as part of real operations.

For some organizations, that means tracking assets across borders. For others, it means monitoring medical devices, automating building compliance, managing energy consumption or operating autonomous equipment. In each case, the value comes when connected infrastructure, data, security and service logic work together.

That is where you have a decisive role to play. You are no longer simply enabling product teams to “connect something”. You are helping define whether a connected product can become a scalable, secure and commercially viable service.

As Boyd puts it: “The question is no longer whether products can be connected. The challenge is ensuring they continue to operate reliably once they move into real-world environments, across markets, networks and day-to-day operations.”
