Engineering Contradiction Analysis
1Productivity
If the electronic device selects the frequency band and bandwidth to perform wireless communication without considering surrounding environment, then communication connection is established, but channel interference occurs and communication performance deteriorates
Solution Approach 1:
The electronic device performs preliminary actions by scanning for external devices and measuring interference levels before establishing a wireless communication connection. The processor determines a recommended bandwidth based on pre-measured interference levels in different bandwidths, ensuring the connection is established with optimal parameters already selected, thereby avoiding channel interference and maintaining communication performance.
2Productivity
If the electronic device uses maximum bandwidth for wireless communication, then data rate increases, but interference from other external devices increases
Solution Approach 1:
The electronic device changes the bandwidth parameter dynamically by measuring interference levels across different bandwidths and selecting the optimal one. The processor compares interference levels in the maximum bandwidth versus reference bandwidths and determines a recommended bandwidth that balances data rate and interference, adjusting the parameter based on actual environmental conditions rather than using a fixed maximum.
Solution Approach 2:
The electronic device implements feedback by measuring actual interference levels in the environment and using this information to determine the recommended bandwidth. The processor receives capability information from external devices, measures interference across different bandwidths, and selects the optimal bandwidth based on this feedback, creating a closed-loop system that adapts to real-time environmental conditions.
