摘要

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.

FIG. 1 illustrates an example architecture of an Adaptive Voltage Modification (AVM) controller that is configured to mitigate an effect of a power interruption that impacts a Remote Radio Unit (RRU) and the operation of Radio Frequency (RF) antennas.

FIG. 2 illustrates a block diagram of various components of an AVM controller.

FIG. 3 illustrates an AVM controller process for performing an analysis of sensor data to quantify a voltage-boost to increase the voltage of a power transmission received at a Remote Radio Unit (RRU).

FIG. 4 illustrates an AVM controller process for performing an analysis using voltage compensation tables to quantify a voltage-boost to increase the voltage of a power transmission received at a Remote Radio Unit (RRU).

FIG. 5 illustrates an AVM controller process for generating an analysis model to preemptively infer power interruption events that may impact an operation of one or more RF antennas.

FIG. 6 illustrates an AVM controller process for initiating a voltage-boost at a point-in-time prior to an inferred power interruption event impacting an operation of one or more RF antennas.

FIG. 7 illustrates an AVM controller process for selectively initiating a voltage-reduction of a power transmission at a Remote Radio Unit (RRU) to protect hardware and software elements from a power surge.
