Solution Overview
Problem
Existing technologies face challenges in implementing effective wireless link quality assessment due to varying wireless channel conditions and interference, which complicates network management in enterprise campus networks.
Innovation Solution
A method for assessing wireless link quality involves monitoring user traffic and wireless channel characteristics to generate link quality factors, which are then used to determine an overall assessment using a truth table, triggering network management actions as necessary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If wireless link quality assessment is implemented using traditional methods, then network coverage and functionality can be increased, but the assessment becomes difficult due to varying wireless channel conditions and interference
Solution Approach 1:
The patent segments the complex wireless link quality assessment into multiple discrete quality factors (signal strength, signal-to-noise ratio, bit error rate, packet loss rate). Each factor is evaluated independently with a fixed number of possible outcomes, making the overall assessment manageable despite varying channel conditions and interference
Solution Approach 2:
The patent introduces a truth table as an intermediary mechanism that systematically combines the discrete outcomes of multiple quality factors to determine the overall link quality assessment. This truth table acts as a mediator that translates complex multi-factor evaluations into a clear overall assessment, resolving the difficulty caused by varying wireless conditions
2Reliability
If multiple wireless link quality factors are monitored to improve assessment accuracy, then the reliability of network management decisions is improved, but the device complexity and computational requirements increase
Solution Approach 1:
The patent divides the assessment into discrete quality factors (signal strength, SNR, BER, packet loss rate), each evaluated independently with a fixed number of possible outcomes. This segmentation allows reliable multi-factor monitoring while keeping each factor's evaluation simple and manageable
Solution Approach 2:
The patent changes the parameters of each quality factor into discrete categories with a fixed number of possible outcomes rather than continuous values. This parameter transformation simplifies the computational requirements while maintaining reliable assessment through the systematic combination of discrete factors using a truth table
