Wireless Module Self-Diagnosis via Overlapping Channel Probing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face challenges in diagnosing and resolving wireless communications issues in electronic devices, as hardware and software faults, along with electrostatic discharge events, can impair communication, making it difficult for users to recognize and fix these problems without professional assistance, which degrades the user experience.
Innovation Solution
A system and method where a second wireless module transmits data on an overlapping channel to obtain a measured response from a first wireless module, allowing a control module to initiate remedial actions, such as resetting, based on the response, thereby self-diagnosing and resolving potential anomalies without user intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If users manually diagnose and fix wireless communications issues, then they can resolve hardware and software faults, but it requires user time and professional assistance which degrades user experience
Solution Approach 1:
The system enables self-diagnosis and self-repair by having the wireless module automatically test its own functionality through probe signals and respond to diagnostic commands without requiring user intervention or professional service personnel
Solution Approach 2:
The system performs preliminary diagnostic actions by automatically initiating communication tests and functionality assessments before user problems occur or escalate, enabling proactive identification and resolution of issues
2Reliability
If the wireless module is reset to resolve anomalies, then communication issues can be resolved, but the reset operation may disrupt ongoing wireless communications
Solution Approach 1:
The system performs wireless communications reliability testing at periodic intervals through automated diagnostic cycles that send probe signals and assess module functionality without continuously disrupting normal operations
Solution Approach 2:
The system conducts preliminary functionality tests and diagnostic assessments before actual communication failures occur, allowing potential issues to be identified and resolved proactively during low-impact periods

AI summary
Methods, devices and systems are provided for diagnosing a wireless module of a device. An exemplary method involves operating a second wireless module of the device to transmit data on a second wireless channel that overlaps, at least in part, a first wireless channel. A measured response associated with the first wireless channel concurrent to the data transmitted on the second wireless channel is obtained from the first wireless module and a remedial action is initiated with respect to the first wireless module based at least in part on the measured response.
