Logistic and Transportation

Wireless devices are projected to bring massive opportunities to the automotive industry and the Fourth Industrial Revolution.

Robotic Assembly Lines and
Self-Driving Cars

A variety of industry segments will benefit from new wireless technologies such as LTE-M and 5G, including:
The vast bandwidth and low latency of these wireless technologies will open new business opportunities as well as bring new challenges. The communication between devices and control systems will need to be unbreakable for continuous operation.

In such mission-critical communication services, continuous and fully-automated testing is crucial to ensure compliance and the identification of corner cases occurring outside of normal parameters. Scenarios must replicate realistic conditions and be verified under multiple, different circumstances.

Automating Data Collection

Smart devices that collect data from sensors and meters need to be automated. This commonly involves integrating low-level ASIC commands, RESTful API, SOAP API, or similar interfaces – all of which the SEGRON Automated Testing Framework (ATF) supports. The interface is used to trigger device events, such as meter value, an alarm, a report, or to initiate a voice channel.

For example, let’s say you have devices with chipsets that have a C library available for development purposes. Wrappers are created for the native library to build an API, which can then be integrated into the testing framework.
The SEGRON ATF inspects the reported data and compares it with the transmitted data to confirm the payload’s integrity and format.

Similarly, this method is used for verifying the quality of audio communication, for example, over the voice channel in LTE-M. The audio is tested with the same ATF audio verification features that are used for mobile devices. An audio sample is played from the device over the voice channel and recorded on the network side (or vice versa). Then the sample and the recorded piece are compared for similarity and quality.

IoT and Other Industrial
Applications

Test cases can be extended with radio control, a handle-able radio environment for stress and robustness testing. Tests can also be combined with packet capture and signalling verification.

After each test execution, the powerful reporting and logging functionality of the SEGRON ATF enables the identification of corner cases occurring outside of normal operating conditions. This ensures that all test-related files, including audio samples and trace files, are stored for post-processing.

Due to its flexible and distributed architecture, the SEGRON ATF integrates smoothly into existing CI/CD pipelines. This allows IIoT and other industrial applications to be tested continuously to ensure quality, consistency and fast identification of faults.
