1. A method of operating a cellular base station, the method comprising:
- supplying a direct current (“
DC”
) power signal from a power supply to a remote radio head that is mounted remotely from the power supply over a power cabling connection that includes a power supply conductor and a return conductor, the power cabling connection including a shunt capacitance unit coupled between power supply conductor and the return conductor;
transmitting an alternating current (“
AC”
) control signal onto the power cabling connection;
receiving the AC control signal after it passes through the shunt capacitance unit; and
determining a resistance or an impedance of the power cabling connection based on the received AC control signal.

Abstract
Tower systems suitable for use at cellular base stations include a tower, an antenna mounted on the tower, a remote radio head mounted on the tower and a power supply. A power cable having a power supply conductor and a return conductor is connected between the power supply and the remote radio head. A shunt capacitance unit that is separate from the remote radio head that is electrically coupled between the power supply conductor and the return conductor of the power cable.
