Remote Controller Power Allocation for Distributed Antenna Units
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In distributed antenna systems, remote antenna units often face power management challenges due to power-consuming components like E/O and O/E converters, where insufficient power distribution can lead to inadequate operation of services, especially when multiple components share limited power resources.
Innovation Solution
A power management system that includes a remote controller to determine and allocate an available power budget to powered ports in remote units, ensuring sufficient power is provided to critical components based on priority services, allowing for efficient distribution of power among modules and devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If power is distributed to multiple components in remote antenna units, then more services can be provided, but power availability for each component decreases
Solution Approach 1:
The system implements feedback mechanisms where the remote controller continuously monitors power consumption of various components and adjusts power distribution dynamically. The controller receives power consumption information from remote units and modifies power allocation based on actual usage patterns, ensuring optimal power utilization while maintaining service availability.
Solution Approach 2:
The power distribution system transitions from static to dynamic allocation. The remote controller can adjust power levels to different components in real-time based on service requirements, component priorities, and available power budget. This dynamic approach allows the system to adapt power distribution to changing operational conditions.
2Reliability
If local power sources are provided at remote antenna units, then power reliability improves, but system complexity increases
Solution Approach 1:
The patent combines multiple power sources (local and remote) into a unified power management system. The remote controller coordinates between central power sources and local power sources at remote units, merging them into a single managed infrastructure that provides redundancy without requiring completely separate power management systems.
Solution Approach 2:
The remote controller acts as an intermediary between the central office power management system and local power sources at remote units. It mediates power allocation decisions, coordinating between remote power sources and local components, thereby reducing the complexity burden on both ends while maintaining reliability.
3Reliability
If power is allocated based on priority services, then critical components receive sufficient power, but power distribution flexibility decreases
Solution Approach 1:
The power allocation system dynamically adjusts priority assignments and power distribution based on real-time service requirements. While critical components maintain priority status, the system can temporarily adjust power allocation during different operational phases, allowing flexible response to changing service demands while maintaining reliability for essential functions.
Solution Approach 2:
The system changes power distribution parameters (voltage, current, allocation ratios) based on service priority levels and operational conditions. By dynamically modifying these parameters, the system maintains reliable power supply to critical components while adapting overall power distribution flexibility to match current service requirements.

AI summary
Power management for remote units in a wireless distribution system. Power can be managed for a remote unit configured to power modules and devices that may require more power to operate than power available to the remote unit. For example, the remote unit may be configured to include power-consuming remote unit modules to provide communication services. As another example, the remote unit may be configured to provide power through powered ports in the remote unit to power-consuming devices. Depending on the configuration of the remote unit, the power-consuming remote unit modules and/or power-consuming devices may demand more power than is available at the remote unit. In this instance, the power available at the remote unit can be distributed to the power-consuming modules and devices based on the priority of services desired to be provided by the remote unit.
