WiFi Module Test Method Using Non-Transmitting Boot Mode
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional test methods for WiFi modules in communication apparatuses are inefficient and prone to errors due to the need for multiple booting operations and interference between devices during testing, especially when switching between RSDB and non-RSDB modes.
Innovation Solution
A communication apparatus and test method where the wireless communication module does not transmit signals before testing, allowing the device to be booted once, and the operation mode is switched by the application unit to test different modes without interfering with other devices, thereby simplifying and reducing the test time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple booting operations are performed to switch WiFi module modes, then the mode can be changed, but the test time increases and the process becomes complicated
Solution Approach 1:
The patent applies preliminary action by pre-configuring the WiFi module to operate in a non-transmitting state before testing begins. This allows the mode switching to be performed through software control (application unit resetting the wireless driver) rather than requiring multiple physical boot operations, thereby reducing test time while maintaining mode adaptability
2Reliability
If WiFi module transmits signals during testing, then the module can be tested in real operating conditions, but it causes interference with other devices being tested
Solution Approach 1:
The patent extracts the harmful transmitting function from the testing process by configuring the WiFi module to remain in a non-transmitting state during tests. The module is tested in this isolated state, and the transmitting capability is verified separately through driver reset operations, thereby eliminating signal interference with other devices while maintaining test reliability
Solution Approach 2:
The patent creates an inert testing environment by preventing the WiFi module from transmitting signals during the testing process. This controlled non-transmitting state isolates the device under test from affecting other devices, similar to creating an inert atmosphere that prevents unwanted reactions
3Reliability
If WiFi module transmits signals during testing, then the module functionality can be verified, but it becomes difficult to identify which device transmits the signal
Solution Approach 1:
The patent introduces an intermediary approach by using the application unit and wireless driver as mediators between the test signals and the WiFi module. The module itself does not transmit, but the driver can be reset to trigger transmissions under controlled conditions, allowing the test device to identify and track signals through the driver reset mechanism rather than directly from the module

AI summary
A communication apparatus (100, 300) including a wireless communication module (110, 310), a wireless driver (120, 320) and an application unit (130, 330) and a test method thereof are provided. The test method includes: after the communication apparatus performs a booting operation, setting an operation mode (MD) as a default mode (MD0) by the wireless driver (120, 320) to activate first (ET1) and second (ET2) wireless interfaces of the wireless communication module (110, 310), and controlling the wireless communication module (110, 310) by the wireless driver (120, 320) to not transmit a wireless signal (WLS), and further includes re-setting the operation mode (MD) according to a test item (TSI), by the application unit (130, 330) when the application unit receives an execution command, so that the wireless driver (120, 320) controls the wireless communication module (110, 310) to transmit the wireless signal (WLS) corresponding to the operation mode (MD).
