This disclosure describes techniques for identifying and mitigating a voltage loss in a power transmission to a Remote Radio Unit (RRU) associated with Radio Frequency (RF) antennas of a telecommunications network. More particularly, a Supplemental Voltage (SV) controller is described that is configured to monitor and detect a change in voltage that occurs during a power transmission from a primary Direct Current (DC) power source to the RRU and selectively cause a supplemental DC power source to transmit a supplemental voltage to the RF antennas. The SV controller may cause a supplemental DC power source to transmit a supplemental voltage to the RRU based on an empirical data analysis, sensory data analysis, or current environmental metadata. Further, the SV controller may determine whether the primary DC power source has suddenly ceased transmitting power to the RRU, and in doing so, cease transmission of a supplemental voltage to the RRU.
