Wireless Communication Channel Selection with Dynamic Quality Thresholds
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in effectively managing communication channels when interference occurs, leading to a shortage of usable channels, which can result in communication errors and impaired interference avoidance functions.
Innovation Solution
A wireless communication system that detects communication quality using characteristic data, deletes channels not meeting a predetermined standard, and switches to channels satisfying a relaxed quality standard to maintain a minimum number of usable channels, thereby reducing communication errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If communication channels with high interference are deleted to maintain communication quality, then communication quality is improved, but the total number of usable communication channels decreases
Solution Approach 1:
The system dynamically adjusts the communication quality standard based on the total number of available channels. When the number of usable channels falls below a predetermined threshold, the system relaxes the quality standard to include channels with higher interference levels, thereby increasing the available channel pool while maintaining acceptable communication quality
Solution Approach 2:
The invention changes the parameter of communication quality standard (threshold for determining usable channels) based on system conditions. By adjusting this parameter dynamically, the system can expand or contract the set of usable channels to maintain both adequate channel quantity and acceptable communication quality
2Reliability
If a strict communication quality standard is applied, then communication errors are reduced, but fewer communication channels remain available for use
Solution Approach 1:
The system employs dynamic adaptation by switching between strict and relaxed quality standards based on the current number of usable channels. This dynamic approach allows the system to maintain high communication quality when sufficient channels are available while ensuring channel availability when the pool is limited
Solution Approach 2:
The system uses feedback from the number of available communication channels to adjust the quality standard. When channel availability drops below a threshold, the feedback mechanism triggers a relaxation of the quality standard, creating a closed-loop control that balances quality and availability
