Engineering Contradiction Analysis
1Productivity
If multiple electronic devices work in the same or adjacent WiFi channels, then the WiFi network can support more users and applications, but channel interference occurs which seriously damages data transmission performance
Solution Approach 1:
The patent implements dynamic adjustment of receiver sensitivity based on real-time channel environment detection. The system continuously monitors channel conditions and adapts the receiver sensitivity threshold dynamically, allowing the WiFi device to optimize its reception capabilities according to the current interference level, thus maintaining reliable data transmission while supporting multiple users in the same or adjacent channels
Solution Approach 2:
The patent changes the receiver sensitivity parameter based on detected channel conditions. By adjusting the sensitivity threshold according to the channel environment, the system can differentiate between relevant signals and interference, thereby maintaining high data transmission performance even when multiple devices operate in the same or adjacent WiFi channels
2Reliability
If receiver sensitivity is increased to improve data reception, then more weak signals can be detected, but channel interference from other devices causes more false detections and reduces transmission success rate
Solution Approach 1:
The patent dynamically adjusts the receiver sensitivity parameter based on real-time channel condition assessment. When channel interference is detected, the system modifies the sensitivity threshold to an optimal value that balances signal detection capability with interference rejection, preventing both missed detections and false detections
Solution Approach 2:
The system implements a feedback mechanism that continuously monitors channel conditions and transmission success rates. Based on this feedback, the receiver sensitivity is automatically adjusted to optimal levels, creating a closed-loop control system that adapts to changing channel environments and maintains reliable communication despite interference from other devices
