In the cellular IoT development process, ensuring the reliability and performance of a device is not just a technical requirement—it’s the cornerstone for the success and adoption of cellular solutions. These factors are critical for several reasons, impacting everything from user experience to the overall success of the solution:
- User Trust and Experience – Devices that deliver consistent performance enhance user satisfaction and contribute to broader adoption.
- Operational Continuity – Reliable devices are essential to prevent system failures that can disrupt productivity and safety, especially in critical sectors like healthcare and industrial automation.
- Data Integrity – Accurate data collection relies on the performance of IoT devices, with device failures potentially skewing important analytics.
- Cost Efficiency –Investing in high reliability and performance from the start can lower long-term costs related to maintenance, troubleshooting, and device replacement.
- Compliance and Standards – Cellular devices must comply with stringent industry certifications that dictate performance standards.
The Role of Testing in Product Development
The testing phase of product development is where critical design decisions are made to support the device’s reliability and performance. The insights gained from reliability testing guide the device’s design and ensure the product exceeds expected standards.
Anechoic Chamber Testing
A key tool in this process is the anechoic chamber, an environment engineered to absorb sound or electromagnetic waves. This eliminates external interference and allows for precise measurement of the device’s performance and connectivity capabilities.

Taoglas’ Approach to Ensuring Cellular Reliability
Taoglas takes a comprehensive approach to reliability testing, as exemplified by the EDGE EM15 System-on-Module in the video above:
- Testing Setup—The EDGE EM15 is connected to a radio communication analyzer within the anechoic chamber. An antenna within the chamber communicates with the module to test its cellular reliability.
- Network Performance Assessment – The module is tested across various network standards, including LTE categories and narrowband IoT, with fallback capabilities across 4G, 3G, and 2G networks.
- Real-World Simulation – By mimicking network conditions, Taoglas engineers can evaluate the device’s performance, pinpoint potential issues, and adjust the design for enhanced connectivity and reliability.
The Gateway to Optimal Connectivity
The testing process is more than a checklist item—it’s a deep dive into the communication capabilities of devices like the EM15. This is crucial to understand how devices will perform in various scenarios, ensuring that a device with Taoglas products can reliably maintain connectivity in any setting.
