Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing signal boosters and repeaters face challenges in dynamically adjusting their gain levels to avoid oscillations, which can lead to network disruptions and premature shutdowns, especially in environments with changing antenna feedback path losses.
Innovation Solution
The solution involves a repeater that measures antenna feedback path loss and sets a maximum gain level with an oscillation margin, allowing it to operate at maximum gain without causing oscillations by dynamically adjusting based on measured path loss changes, thereby preventing network disruptions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the repeater operates at maximum gain to improve signal quality, then the signal amplification performance is improved, but oscillations may occur causing network disruptions
Solution Approach 1:
The system continuously measures the antenna feedback path loss and uses this feedback to dynamically adjust the maximum gain level. The controller monitors the feedback path characteristics and adjusts the gain accordingly to maintain optimal signal quality while preventing oscillations. This closed-loop feedback mechanism resolves the contradiction by enabling the repeater to operate at the highest safe gain level without causing harmful oscillations.
Solution Approach 2:
The system transitions from a static gain configuration to a dynamic gain adjustment mechanism. The maximum gain level is no longer fixed but is continuously adapted based on measured antenna feedback path loss conditions. This dynamic approach allows the repeater to optimize signal quality in real-time while automatically preventing oscillations by adjusting gain according to changing environmental conditions.
2Stability of the object's composition
If the repeater uses a fixed gain level to avoid oscillations, then network stability is maintained, but the signal amplification performance is limited
Solution Approach 1:
The system replaces fixed gain configuration with dynamic gain adjustment based on real-time measurements of antenna feedback path loss. The controller continuously adapts the maximum gain level to match current environmental conditions, enabling the system to achieve both network stability and optimal signal amplification performance. This dynamic approach eliminates the need to compromise performance for stability.
Solution Approach 2:
The system changes the gain parameter dynamically based on measured feedback path loss characteristics. By continuously monitoring and adjusting the gain parameter according to environmental conditions, the system optimizes signal amplification performance while maintaining network stability. This parameter adaptation resolves the contradiction between fixed stability and variable performance requirements.
3Power
If the repeater increases gain to compensate for path loss, then the signal strength is improved, but the risk of oscillation increases
Solution Approach 1:
The system uses feedback from path loss measurements to determine the appropriate gain level. By continuously monitoring the antenna feedback path loss and adjusting gain accordingly, the system maximizes signal strength while maintaining a safe margin below oscillation thresholds. This feedback-controlled approach enables the repeater to operate at the highest reliable gain level without increasing oscillation risk.
Solution Approach 2:
The system takes preliminary action by measuring the feedback path loss before setting the gain level. By characterizing the feedback path characteristics in advance and establishing an oscillation margin, the system prevents oscillations before they can occur. This proactive approach allows the system to set maximum gain levels that are optimized for signal strength while inherently preventing oscillation risks.
