Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for determining wireless communication reliability in networks with multiple electronic devices are cumbersome and time-consuming, requiring proprietary tools to assess parameters like RSSI, LQI, and SNR, and do not easily translate to physical location of communication issues, especially in large-scale deployments.
Innovation Solution
Implement systems and methods for electronic devices and access points to track and display link quality information, including RSSI, LQI, and SNR, using a processor and memory to convert quantitative data into qualitative status indicators, such as color codes, allowing easy identification of communication issues and optimization of network reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If proprietary tools are used to assess link quality parameters (RSSI, LQI, SNR), then measurement precision is improved, but device complexity and ease of operation deteriorate
Solution Approach 1:
The system enables electronic devices to automatically track and report their own link quality parameters (RSSI, LQI, SNR) without requiring external proprietary assessment tools. Each device monitors its communication links and provides self-diagnostic information, eliminating the need for complex external measurement equipment while maintaining measurement precision.
Solution Approach 2:
The patent introduces a controller as an intermediary that collects link quality information from multiple electronic devices and coordinates the assessment process. This centralized mediator simplifies the overall system architecture by consolidating the assessment function, allowing precise measurement without requiring each device to have complex built-in diagnostic capabilities.
2Measurement precision
If detailed link quality parameters are tracked for multiple devices, then measurement precision is improved, but ease of operation deteriorates
Solution Approach 1:
The system converts complex quantitative link quality parameters into intuitive visual color indicators. Electronic devices display color-coded status information (e.g., green for good quality, red for poor quality) that allows users to quickly assess communication reliability without needing to interpret technical parameters like RSSI, LQI, or SNR values, thereby maintaining measurement precision while dramatically improving ease of operation.
3Reliability
If comprehensive link quality tracking is implemented across the network, then reliability is improved, but loss of time increases due to data collection and processing
Solution Approach 1:
The system continuously tracks and pre-processes link quality information in the background before diagnostic queries are initiated. Electronic devices maintain up-to-date link quality metrics and make this information readily available, so when a diagnostic assessment is needed, the controller can immediately retrieve and analyze the data without requiring time-consuming real-time measurements or data collection processes.
4Reliability
If real-time link quality monitoring is implemented, then reliability is improved, but use of energy increases
Solution Approach 1:
Instead of continuous real-time monitoring, the system implements periodic link quality assessments at predetermined intervals. Electronic devices update their link quality information and report to the controller at scheduled times, which maintains adequate monitoring reliability for diagnostic purposes while significantly reducing energy consumption compared to continuous monitoring. The periodic updates occur sufficiently often to detect communication issues but infrequently enough to conserve device battery power.
