At 402, the AVM controller may monitor, via one or more sensor(s), a voltage output from a DC power source. The AVM controller may monitor the one or more sensor(s) on a continuous basis, per a predetermined schedule, or in response to a triggering event. The predetermined schedule may be based on a time interval of one hour, six hours, or 12 hours. Any time interval is possible. Further, the triggering event may correspond to receipt of an indication that at least one QoS parameter associated with signal data (i.e. voice and data communications) transmitted by the RF antennas has fallen below a predetermined QoS threshold. The QoS parameters may relate to data packet loss, data latency, jitter, echo, downlink throughput, uplink throughout, or any combination thereof. In some examples, the AVM controller may receive an indication of QoS parameters from an enterprise server of the telecommunications network or client device that is experiencing a reduction in QoS. Further, the predetermined thresholds may be set by an operator of the AVM controller or an administrator of the telecommunications network.

At 404, the AVM controller may quantify a voltage of the power transmission at the RRU, based at least in part on the voltage compensation tables. The AVM controller may receive an input of voltage output from the DC power source and, using the voltage compensation tables, output the voltage of the power transmission at the RRU. In some examples, the voltage compensation tables may be based on properties of the cables, such as cable length, cable resistance coefficient, and cable diameter.
