Innovation Solution
A method and system that determine route quality indicators for each communication route associated with multiple antennas, allowing for the selection of the optimal antenna for video and audio data transmission, including network statistics, radio performance metrics, and user performance metrics, and enabling seamless transitions to improve video conferencing quality by switching to higher quality networks or antennas when conditions allow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the system uses a single antenna for video conferencing, then the device complexity is reduced, but the video conferencing quality and reliability deteriorate under varying network conditions
Solution Approach 1:
The system dynamically selects among multiple antennas based on real-time route quality indicators. The antenna selection is not fixed but changes adaptively according to network conditions, allowing the system to maintain reliable video conferencing quality while managing device complexity through software-controlled selection rather than hardware redundancy for each scenario
Solution Approach 2:
The system changes the operational parameter of antenna selection based on route quality indicators. By monitoring network statistics, radio performance metrics, and user performance metrics, the system selects the optimal antenna configuration for current conditions, improving reliability without permanently increasing device complexity
2Reliability
If the system dynamically switches between multiple antennas based on route quality, then the video conferencing quality is improved, but the device complexity increases
Solution Approach 1:
The system implements a feedback mechanism where route quality indicators (network statistics, radio performance metrics, user performance metrics) are continuously monitored and fed back to the antenna selection logic. This automated feedback loop improves video conferencing quality by responding to changing conditions while managing complexity through algorithmic decision-making rather than manual configuration
Solution Approach 2:
The antenna selection system operates autonomously by automatically monitoring route quality indicators and selecting the appropriate antenna without user intervention. This self-service approach improves video conferencing quality while managing complexity by embedding the selection logic within the system's existing processing architecture
3Measurement precision
If the system monitors multiple route quality indicators for antenna selection, then the selection accuracy is improved, but the processing time and energy consumption increase
Solution Approach 1:
The system monitors multiple route quality indicators including network statistics, radio performance metrics, and user performance metrics to achieve precise antenna selection. By comprehensively evaluating these parameters, the system improves measurement precision of route quality while managing processing time through efficient evaluation algorithms that prioritize critical metrics
4Adaptability or versatility
If the system switches antennas during video conferencing, then the adaptability to network conditions is improved, but the stability of the connection may be reduced due to transition disruptions
Solution Approach 1:
The system dynamically adapts to network conditions by switching between antennas based on real-time route quality indicators. This dynamic behavior improves adaptability to varying network conditions while managing connection stability through controlled transition mechanisms that minimize disruptions during antenna switching
