1Reliability
If MIMO antenna systems operate in a fixed mode, then device complexity is reduced, but communication signal quality deteriorates under varying environmental conditions
Solution Approach 1:
The system measures the multi-path power metric of received communication signals and uses this feedback to dynamically select the appropriate antenna operating mode. The control logic continuously monitors the multi-path power metric and adjusts the operating mode accordingly, ensuring optimal signal quality while adapting to changing environmental conditions.
Solution Approach 2:
The antenna system transitions from a static fixed mode operation to a dynamic mode selection system. The control logic enables real-time switching between different operating modes based on the measured multi-path power metric, allowing the system to adapt its characteristics to match current environmental conditions and maintain optimal performance.
2Productivity
If the wrong antenna operating mode is selected, then device complexity is reduced, but data throughput deteriorates
Solution Approach 1:
The control logic uses the measured multi-path power metric as feedback to determine the optimal operating mode for maximizing data throughput. By continuously monitoring this metric and selecting modes based on predetermined thresholds, the system ensures high productivity without requiring complex manual intervention or trial-and-error mode selection.
Solution Approach 2:
The system changes operational parameters (antenna operating modes) based on the measured multi-path power metric. Different modes are optimized for different multi-path conditions, and the control logic selects the appropriate mode by comparing the metric against predetermined thresholds, thereby maximizing data throughput for current channel conditions.
3Reliability
If antenna modes are dynamically switched based on multi-path power metric, then communication signal quality is improved, but device complexity increases
Solution Approach 1:
The antenna system performs self-diagnosis and self-adjustment by measuring its own multi-path power metric and automatically selecting the appropriate operating mode. The control logic monitors the system's own performance characteristics and makes autonomous decisions about mode selection, eliminating the need for external intervention or complex manual control mechanisms.
Solution Approach 2:
The system implements a closed-loop control mechanism where the multi-path power metric is measured, compared against thresholds, and used to control mode selection. This feedback-driven approach ensures optimal signal quality while keeping the control logic relatively simple, as it only requires threshold comparisons rather than complex optimization algorithms.
4Adaptability or versatility
If fixed antenna operating mode is used, then ease of operation is improved, but adaptability to environmental conditions deteriorates
Solution Approach 1:
The system automatically adapts to environmental conditions by measuring the multi-path power metric and selecting appropriate modes without user intervention. This self-service capability provides full environmental adaptability while maintaining ease of operation, as users simply need to operate the device normally without manually adjusting modes or configuring settings.
Solution Approach 2:
The antenna system transitions from a static fixed mode to a dynamic adaptive mode selection system. The control logic enables real-time adaptation to changing environmental conditions by switching modes based on the measured multi-path power metric, providing both adaptability and operational simplicity through automated control.
