Wireless Device Test Result Communication via Non-Link Data Packets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional wireless device testing methods require costly and time-consuming link-based connections for communicating test results, which is inefficient in production line settings where hardware failures are the primary concern, especially in devices without external ports due to aesthetics or sealing needs.
Innovation Solution
The method involves combining test data with other data to form packets that include a portion designated for identifying the device or tester, allowing test results to be transmitted via conductive or radiative data packet signal paths, utilizing existing system features and protocols to convey results without an active upper protocol stack connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If link-based testing methods are used to communicate test results, then test result communication is reliable, but test time increases and communication overhead increases
Solution Approach 1:
The patent segments the data packet structure into distinct fields, embedding test result information within existing packet structures (such as MAC address fields or data payload) rather than requiring separate communication protocols. This allows test results to be transmitted as part of normal data packets, eliminating the need for dedicated link-based communication channels and reducing overall test time while maintaining reliability.
Solution Approach 2:
The patent combines test result communication with existing data packet transmission protocols. By merging test data into standard data packets that already traverse the communication channel, the system eliminates redundant communication overhead and reduces test time while maintaining the reliability of established protocols for delivering test results.
2Reliability
If link-based testing methods are used to communicate test results, then test result communication is reliable, but communication overhead increases
Solution Approach 1:
The patent makes the data packet structure universal by designing it to carry both normal data traffic and test result information simultaneously. The same packet infrastructure used for regular communications is repurposed to convey test results, eliminating the need for separate communication channels and reducing overall system complexity and overhead.
Solution Approach 2:
The system uses existing data packet structures and communication protocols to carry test results without requiring additional communication infrastructure or protocols. The normal data transmission system serves dual purposes by also transporting test information, thereby reducing communication overhead and simplifying the overall system architecture.
3Ease of operation
If external ports are added to devices for testing, then test result communication is simplified, but device aesthetics deteriorate and sealing requirements increase
Solution Approach 1:
The patent extracts the test result communication function from physical external ports and implements it through existing wireless communication interfaces. By removing the need for dedicated test ports and utilizing standard wireless data transmission, the system maintains device aesthetics and sealing integrity while still enabling straightforward test result communication through software-based solutions.
4Ease of operation
If external ports are added to devices for testing, then test result communication is simplified, but device sealing requirements increase
Solution Approach 1:
The patent removes the requirement for physical external ports by extracting the test communication function and implementing it through existing sealed wireless interfaces. This approach maintains device sealing integrity and protection against environmental factors while still enabling easy test result communication through software-based data transmission over existing communication channels.
Data Source
AI summary
A method for communicating test results from a wireless device under test (DUT) using non-link testing resources. Test data resulting from testing one or more operations of the DUT are combined with other data to form one or more data packets for transmission to a tester. The test data occupies, e.g., via encoding, a portion of the one or more data packets designated for data identifying the DUT or a tester.
