Antenna Control Algorithm for Mobile Repeater Beam Direction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile repeaters with single antenna configurations face challenges in maintaining adequate signal quality as they move, as they cannot adaptively adjust beam patterns to track incoming signals or scan for better donor signals without complex and expensive multi-beam antenna systems.
Innovation Solution
Implementing an antenna control algorithm that selects an optimum antenna configuration at startup, maintaining it until performance metrics drop below a level, then scanning for a new configuration, and a speed-optimized algorithm that scans for better configurations only when performance falls below a minimum, allowing for dynamic management of radiation patterns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single antenna configuration is used in mobile repeaters, then device complexity is reduced, but the ability to maintain signal quality during movement deteriorates
Solution Approach 1:
The patent implements dynamic antenna configuration management where the system automatically switches between different antenna configurations based on real-time signal quality metrics. The controller monitors performance and activates alternative configurations when signal quality degrades, enabling the single antenna system to adapt dynamically to movement-induced signal variations without requiring complex multi-beam hardware.
2Adaptability or versatility
If antenna configurations are continuously scanned to track incoming signals, then signal tracking capability is improved, but device complexity and cost increase
Solution Approach 1:
The patent employs periodic scanning of antenna configurations triggered by signal quality thresholds rather than continuous scanning. The controller monitors signal metrics and only initiates configuration scans when performance degradation is detected, implementing a demand-driven periodic scanning approach that maintains tracking capability while minimizing the operational complexity of the antenna system.
Solution Approach 2:
The system performs self-diagnosis and self-adjustment by automatically monitoring its own signal quality metrics and autonomously selecting appropriate antenna configurations without external intervention. This self-service mechanism enables the system to maintain adaptability through intelligent automation rather than complex hardware controls.
3Adaptability or versatility
If antenna configurations are frequently updated to scan for better donor signals, then adaptability to new signals is improved, but loss of time and operational efficiency worsen
Solution Approach 1:
The patent implements a feedback-driven configuration update mechanism where the controller continuously monitors signal quality metrics and uses this feedback to determine when configuration scanning is necessary. By updating configurations only when performance thresholds are breached, the system achieves timely adaptation to better donor signals while minimizing unnecessary scanning operations that would cause time loss and operational interruptions.

AI summary
An antenna control algorithm is disclosed. Using this algorithm, the repeater will select an optimum antenna configuration at start-up. Once the configuration is selected, the system will keep this configuration until the performance metrics for this configuration drops below a specified level. At this point, the system will scan all antenna configurations to determine a new optimum configuration. In an alternative implementation, the repeater will select an optimum antenna configuration at start-up. Once the configuration is selected, the system will keep this configuration until the performance metrics for this configuration drops below a specified level. At this point, the system will start scanning antenna configurations to find a new configuration that yields a performance better than the required minimum performance level. This configuration would typically be faster than an optimum configuration as not all possible options need to be tested.
