Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional testing equipment is used to test access point reception performance, then measurement precision is improved, but device complexity and time consumption increase
Solution Approach 1:
The access point performs self-testing by using itself as both the device under test and the testing equipment. The AP transmits test packets to neighboring APs and measures throughput automatically, eliminating the need for external testing equipment and reducing device complexity while maintaining measurement precision.
Solution Approach 2:
The access point is designed to perform multiple functions: normal wireless communication and self-performance testing. By integrating testing capabilities into the existing AP hardware and software, the system avoids adding separate dedicated testing equipment, thus reducing overall device complexity.
2Measurement precision
If traditional physical connection testing is performed, then measurement precision is improved, but loss of time increases
Solution Approach 1:
The access point continues its normal wireless communication operations while simultaneously performing throughput testing with neighboring APs. The testing is conducted during regular operational hours without requiring the AP to be taken offline, thus eliminating time loss and maintaining continuous useful action.
Solution Approach 2:
The AP uses its own operational traffic and neighboring APs as test subjects, allowing throughput measurement during normal service provision. This self-service approach eliminates the need to stop the AP for testing, thereby reducing time loss while maintaining measurement precision.
3Measurement precision
If access point operation is stopped for testing, then measurement precision is improved, but productivity decreases
Solution Approach 1:
The access point maintains continuous service provision to clients while performing throughput testing with neighboring APs in the background. The testing operations do not interrupt normal wireless communication, thus preserving productivity and service availability while achieving accurate measurement.
Solution Approach 2:
The access point performs testing operations during low-traffic periods or in coordination with neighboring APs without disrupting normal service. By planning tests during appropriate times and using neighboring APs as test subjects, the system achieves measurement precision without significantly impacting productivity.
