1. A method of powering at least one radio, the method comprising:

  • obtaining a resistance of a power cabling connection between a power supply and the at least one radio;

    outputting direct current (DC) power, comprising a voltage, from the power supply;

    supplying the DC power that is output from the power supply to the at least one radio over the power cabling connection;

    measuring a current level of the DC power;

    automatically adjusting a voltage level of the DC power using the obtained resistance and changes in the measured current level of the DC power so that a voltage at the at least one radio remains at a desired voltage level or a voltage within a desired voltage level range;

    wherein a voltage drop in the power cabling connection is the current level multiplied by the resistance;

    wherein the voltage level of the DC power is equal to the desired voltage level, or the voltage within the desired voltage level range, plus the voltage drop;

    wherein obtaining the resistance comprises;

    transmitting a voltage pulse onto the power cabling connection at a first end of the power cabling connection; and

    measuring a return pulse that is reflected from the second end of the power cabling connection, where the second end is opposite the first end.
