Test Interface Segmentation for Wireless Device Validation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current testing methods for communication devices are complex and inefficient, requiring establishment of a communication connection via the device's communication interface, which complicates the testing process and introduces errors, especially during development and production.
Innovation Solution
A test method that separates the communication interface and test interface logically, allowing direct transmission of test commands to the device under test via a dedicated test interface, enabling quick and efficient communication without prior establishment of a communication connection, using a measurement unit to transmit, generate, and evaluate communication signals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If communication connection is established via communication interface for testing, then device can be tested according to communication standard, but testing procedure becomes complex and error-prone
Solution Approach 1:
The patent segments the testing system into two distinct interfaces: a communication interface for standard communication and a test interface for testing operations. This segmentation allows test commands to be transmitted directly without requiring establishment of a full communication connection, thereby simplifying the testing procedure while maintaining testing accuracy.
Solution Approach 2:
The patent introduces a test interface as an intermediary channel between the measurement unit and the device under test. This intermediary allows direct transmission of test commands and reception of test responses, bypassing the complex communication connection establishment process while ensuring reliable test data exchange.
2Adaptability or versatility
If full communication interface is used for testing, then complete communication protocol is available, but testing cannot be performed in early development stage with reduced peripherals
Solution Approach 1:
The testing interface is segmented as a separate functional unit that can operate independently of the full communication interface. This allows the test interface to be implemented with minimal peripherals in early development stages, while the complete communication interface can be added later without affecting the testing capability.
Solution Approach 2:
The test interface enables preliminary testing actions to be performed before the complete communication interface is available. By providing a simplified testing channel that requires fewer peripherals, developers can conduct early-stage testing and validation without waiting for the full communication stack to be implemented.

AI summary
A test method for testing a device under test with a measurement unit comprises transmitting a number of test commands from the measurement unit to the device under test via a test interface of the device under test, generating in the device under test in response to the test commands respective communication signals, emitting by the device under test the generated communication signals via a wireless communication interface, receiving signals from the device under test in the measurement unit, and evaluating the received signals in the measurement unit.
