Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the access point apparatus selects the wireless channel having the higher transmission rate, then the transmission speed is improved, but the transmission efficiency degrades when the wireless channels are overcrowded
Solution Approach 1:
The patent implements dynamic channel selection by continuously monitoring communication parameters (signal strength, interference level, channel occupancy) and adjusting channel selection based on real-time conditions. The system calculates a channel quality metric that combines multiple factors and dynamically switches to the optimal channel, resolving the contradiction between selecting high transmission rate channels and avoiding overcrowded channels.
Solution Approach 2:
The access point apparatus periodically collects communication parameters from the wireless channel and uses this feedback to evaluate channel quality. The system calculates channel quality metrics based on collected parameters and adjusts channel selection accordingly, creating a closed-loop control system that balances transmission rate and channel crowding to optimize overall transmission efficiency.
2Adaptability or versatility
If the access point apparatus uses a fixed channel selection method, then the device complexity is reduced, but the system cannot adapt to instant data transmission conditions
Solution Approach 1:
The access point apparatus autonomously monitors communication parameters, evaluates channel quality, and performs self-adjustment of channel selection without external intervention. The system automatically calculates channel quality metrics and switches channels based on real-time conditions, achieving adaptability through self-service operation while keeping the implementation relatively simple.
Solution Approach 2:
The patent changes the operational parameter of channel selection from a fixed configuration to a dynamic parameter that adjusts based on monitored communication conditions. By continuously evaluating parameters such as signal strength, interference level, and channel occupancy, the system adapts to instant data transmission conditions while maintaining manageable complexity through standardized evaluation metrics.

AI summary
The present disclosure discloses an access point communication method having dynamic channel selection mechanism used in an access point apparatus that includes steps outlined below. A wireless communication is performed with a station apparatus through a neighboring relay access point apparatus. Communication parameters related to the wireless communication are collected periodically. A required data flow amount of the station apparatus is calculated according to the communication parameters and available data flow amounts of wireless channels between the access point apparatus and the relay access point apparatus are calculated. Ratios between the required data flow amount and the available data flow amounts are calculated as channel crowding parameters. One of the wireless channels corresponding to one of the channel crowding parameters having a smallest value is selected to be a selected wireless channel to perform packet transmission to the station apparatus through the relay access point apparatus.
