Supplemental Voltage Control for RRU Power Drop Compensation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Telecommunication service providers face significant financial burdens and service disruptions due to unexpected power losses affecting Radio Frequency (RF) antennas, which can be caused by hardware failures, software issues, or network congestion, leading to compromised communication quality.
Innovation Solution
A Supplemental Voltage (SV) controller is implemented to monitor voltage changes in power transmissions to Remote Radio Units (RRUs) and activate a supplemental DC power source to maintain a predetermined voltage threshold, ensuring continuous and quality communication services by compensating for voltage drops using sensors and machine learning algorithms to anticipate and mitigate power interruptions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a primary DC power source is used to supply power to RF antennas, then the system structure is simple, but voltage drops occur during power transmission that compromise communication quality
Solution Approach 1:
The power supply system is segmented into a primary DC power source and a supplemental DC power source. The primary power source handles normal operation while the supplemental power source compensates for voltage drops, dividing the power supply function to maintain voltage thresholds and ensure communication quality without requiring complete system redesign
Solution Approach 2:
A supplemental DC power source acts as an intermediary between the primary power source and the RF antennas. This intermediary provides additional voltage compensation during transmission, ensuring that voltage thresholds are maintained at the antenna level despite distance or load variations
2Reliability
If voltage compensation is implemented to maintain power transmission quality, then communication service reliability is improved, but device complexity increases
Solution Approach 1:
The system implements feedback through a controller that monitors voltage levels from sensors and dynamically adjusts the supplemental power source output. This closed-loop feedback mechanism automatically maintains voltage within thresholds without manual intervention, improving reliability while keeping the control logic centralized and manageable
Solution Approach 2:
The supplemental power source system is designed to self-regulate based on voltage monitoring. When voltage drops are detected, the system automatically activates compensation; when voltage is sufficient, compensation is reduced or stopped. This self-service capability reduces the need for complex external control mechanisms
Data Source
AI summary
This disclosure describes techniques that enable a supplemental voltage to be delivered to a Remote Radio Unit (RRU) to compensate for a voltage loss that occurs between a primary Direct Current (DC) power source and the RRU. A supplemental voltage controller is described that captures current environmental metadata associated with an operation of the RRU and calculates an RRU voltage at the RRU. In doing so, the supplemental voltage controller may generate a supplemental voltage control signal that supplements the RRU with a supplemental DC voltage.
