Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a channel scanning operation is performed to determine a better channel, then wireless communication performance is improved, but receiver efficiency is influenced and communication is interrupted
Solution Approach 1:
The wireless communication device is divided into two independent paths: a communication path for normal data transmission and a channel detection path for scanning and detecting available channels. This segmentation allows channel scanning to occur without interrupting the communication path, thus maintaining receiver efficiency while improving wireless communication performance through better channel selection.
Solution Approach 2:
The channel detection path performs preliminary channel scanning and detection operations in advance, identifying suitable channels before the communication path needs to switch. This preliminary action allows the communication path to switch channels proactively without interrupting ongoing communications, maintaining both performance and efficiency.
2Adaptability or versatility
If the device prepares to use a DFS channel, then channel selection flexibility is improved, but continuous monitoring for several minutes is required affecting communication continuity
Solution Approach 1:
The channel detection path performs preliminary monitoring and detection of DFS channels in advance, completing the required several minutes of monitoring before the communication path needs to use the channel. This ensures channel availability criteria are met while maintaining communication continuity on the original channel during the monitoring period.
Solution Approach 2:
By separating DFS channel monitoring into an independent channel detection path, the system can monitor DFS channels for the required duration without affecting the communication path's continuity. The communication path remains uninterrupted while the detection path independently performs the time-consuming monitoring task.
3Reliability
If channel switching is performed to avoid interference, then wireless communication performance is improved, but communication interruption occurs during switching
Solution Approach 1:
The channel detection path identifies suitable target channels in advance before the communication path needs to switch. By having channel switching information prepared beforehand, the actual switching operation can be executed quickly with minimal interruption, as the communication path only needs to switch to a pre-identified channel rather than searching during the transition.
Solution Approach 2:
The channel detection path continuously monitors channel conditions and provides feedback about available channels to the communication path. This feedback mechanism allows the communication path to switch channels based on real-time channel quality information, ensuring performance improvement while minimizing interruption by switching only when necessary and to pre-verified good channels.
