Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Telecommunications service providers face significant financial burdens due to power interruptions at cell sites, which can disrupt communication services and require costly field repairs, especially when power surges or disruptions affect Remote Radio Units (RRUs) and Radio Frequency (RF) antennas.
Innovation Solution
The deployment of an Adaptive Voltage Modification (AVM) controller that monitors voltage changes in power transmissions from a DC power source to RRU, using sensors and potential transformers to incrementally boost or reduce voltage, ensuring it remains within a predetermined range (50-57.5 volts) to maintain Quality of Service (QoS) parameters, and employs machine learning algorithms to preemptively mitigate power interruptions and surges.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If voltage is increased to maintain QoS during power interruptions, then communication service reliability is improved, but risk of hardware damage from power surges increases
Solution Approach 1:
The system dynamically adjusts voltage levels in real-time based on monitored power conditions. The AVM controller continuously monitors voltage from the DC power source and controls the potential transformer to step-up or step-down voltage as needed, transitioning from static voltage supply to adaptive dynamic voltage management that responds to changing power conditions.
Solution Approach 2:
The system implements closed-loop feedback control where sensors monitor voltage at the RRU and feed this information back to the AVM controller. The controller analyzes this feedback and adjusts the potential transformer accordingly to maintain voltage within the predetermined range, ensuring reliable operation while preventing damage from surges.
Solution Approach 3:
The system performs preliminary voltage adjustment before power interruptions or surges occur. By monitoring power conditions and predicting potential issues, the AVM controller proactively modifies voltage levels to prevent QoS degradation and hardware damage, rather than reacting after problems occur.
2Reliability
If manual monitoring and repair of power interruptions is performed, then power service stability is improved, but operational cost and time consumption increase
Solution Approach 1:
The system enables self-service operation where the AVM controller automatically detects power conditions, analyzes sensor data, and adjusts voltage without human intervention. The system self-manages the entire process from monitoring to correction, eliminating the need for manual field repairs and reducing operational costs while maintaining power service stability.
Solution Approach 2:
The system replaces manual mechanical monitoring and repair processes with automated electronic control. Sensors, processors, and automated voltage control substitute for human technicians physically monitoring and repairing power equipment, dramatically improving operational efficiency while maintaining reliability.
3Object-affected harmful factors
If voltage is reduced to protect hardware from power surges, then hardware protection is improved, but QoS parameters and communication service quality deteriorate
Solution Approach 1:
The system dynamically adapts voltage levels based on real-time power conditions rather than using fixed reduced voltage. The potential transformer continuously adjusts voltage within the predetermined range (50-57.5 volts) to provide hardware protection while maintaining adequate voltage for QoS, transitioning from static protective reduction to dynamic adaptive voltage management.
Solution Approach 2:
The system changes voltage parameters adaptively within an optimized range. Rather than simply reducing voltage for protection, the AVM controller maintains voltage within the predetermined range (50-57.5 volts) that balances hardware protection with QoS requirements, optimizing both protection and service quality simultaneously.

AI summary
This disclosure describes techniques to identify and mitigate an effect of a power interruption that impacts the operation of Radio Frequency (RF) antennas associated with a telecommunications network. More specifically, an Adaptive Voltage Modification (AVM) controller is described that is configured to monitor and detect a change in voltage that occurs during a power transmission from a Direct Current (DC) power source to a Remote Radio Unit (RRU). A power interruption may include a power disruption or a power surge. The AVM controller may be configured to cause a potential transformer that is coupled between the DC power source and the RRU to incrementally step-up or step-down the voltage of a power transmission from the DC power source. In this way, the AVM controller may preemptively mitigate an impact of a power interruption on Quality of Service (QoS) parameters associated with signal data transmitted by the RF antennas.
