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.

In some examples, the AVM controller 102 may monitor and analyze sensor data 130(1)-130(M) from the one or more sensor(s) 128(1)-128(N) to quantify voltage loss that occurs during a power transmission from the DC power source 114 to the RRU 104. In other examples, the AVM controller 102 may infer voltage loss at the RRU 104 based on a combination of sensor data 130(1)-130(M) and empirical data accessible by the AVM controller 102. For purposes of clarity,
