The Hidden Challenges of IoT Connectivity

In the fast-paced world of IoT, connectivity is often overlooked during the Proof of Concept (POC) phase. This oversight can lead to significant problems down the line. Companies frequently rush ahead with hardware development, edge logic, and application integration, only to encounter connectivity issues later. Common challenges include poor signal penetration, roaming inconsistencies, incompatible radio modules, and data session failures. These issues are not hypothetical—they are frequent and costly, leading to project delays and increased expenditure.

The reality is that a device that performs flawlessly in a controlled lab environment may behave very differently once deployed in the field. Variables such as operator availability, signal interference, roaming agreements, network latency, and even the device’s power conditions can all impact connectivity. These factors highlight the importance of thorough testing in real-world conditions to ensure reliable and consistent performance.

Why POC Testing is Essential for IoT Projects

According to GSMA Intelligence, more than 40% of global IoT projects fail at the POC stage, with unreliable or misunderstood connectivity being one of the top reasons. This statistic underscores the importance of rigorous POC testing. Inadequate connectivity testing can result in widespread issues such as battery drain, missing data, troubleshooting costs, and even failed deployments.

POC testing is not merely a technical task; it is a strategic milestone. A successful POC test provides a validated foundation for network and carrier decisions, confidence in device design and connectivity architecture, and internal assurance for go-to-market timelines and investment. By investing in thorough POC testing, companies can avoid costly surprises later in the deployment lifecycle and ensure a smoother path to compliance and customer delivery.

However, a POC is more than just a technical exercise—it is a strategic milestone in the development process. A successful POC provides a validated foundation for network and carrier decisions, confidence in device design and connectivity architecture, and internal assurance for go-to-market timelines and investment.

In addition to validating connectivity performance, a POC can also be used to evaluate bespoke features for a specific customer, allowing them to gain early access and tangible insight into how the feature performs under real-world conditions. This approach not only strengthens customer engagement but also accelerates innovation and solution refinement ahead of full-scale deployment.

By investing in thorough POC testing, companies can avoid costly surprises later in the deployment lifecycle and ensure a smoother path to compliance and customer delivery.

Field-Level Validation is a Real-World Necessity

Lab tests can only go so far in replicating real-world conditions. Field-level validation is essential for understanding how devices will perform in the environments where they will actually be used. Testing in live environments allows companies to answer critical questions that directly impact cost, customer experience, and long-term scalability.

Field-level validation helps confirm network behavior, device performance across various technologies (such as 2G, 3G, 4G, LTE-M, or NB-IoT), handoff success and latency across networks or borders, device session stability, and power use under weak signal conditions. Additionally, it ensures that SIM and platform integration is effective, monitoring, lifecycle control, and security policies are in place, and future scalability for automation, billing, and diagnostics is prepared. Without this level of validation, companies risk deploying devices that may not function as expected in their intended environments.

The Strategic Advantage of Comprehensive Connectivity Testing

Connectivity testing is no longer a back-office task—it’s a strategic enabler. Comprehensive testing provides confidence that devices will perform consistently across global networks, regulatory environments, and user conditions.

Companies that invest in POC and field testing early benefit from:

• Reduced deployment risk and faster time-to-market

• Validated connectivity architecture that scales globally

• Better investment predictability and customer confidence

• Enhanced compliance with security and performance standards

By treating connectivity testing as a competitive advantage rather than a cost, organizations position themselves for long-term success. The return isn’t just technical—it’s commercial.

FAQ — Key Questions About IoT Connectivity Testing

1. Why does connectivity fail in so many IoT projects?
Because it’s often deprioritized during early development. Many teams assume lab success equals field success, but external variables—like network coverage, roaming, or latency—can cause real-world failures.

2. How can POC testing reduce IoT project failure rates?
A POC validates every layer of connectivity—from SIM behavior to carrier performance—before full rollout. It helps identify and fix costly issues early.

3. Can a POC test customized or bespoke features?
Yes. POC testing can evaluate bespoke functionality for specific customers, giving them early access and letting companies refine those features based on real-world feedback.

4. Why is field-level validation necessary if lab testing passes?
Because lab conditions can’t mimic network variability, interference, or environmental stress. Field-level testing ensures devices behave reliably in actual deployment environments.

5. What role does Velos IoT’s Starter Kit play in testing?
It allows companies to test connectivity performance under real-world conditions using multiple SIM types and networks—supported by Velos IoT’s Nomad platform for data visibility and analysis.
