11. A method of operating a cellular base station, the method comprising:
-
outputting a direct current (“
DC”
) power signal from a power supply and supplying the DC power signal that is output from the power supply to a remote radio head that is mounted remotely from the power supply over a trunk cable and a jumper cable that are connected in series, the jumper cable including a power supply conductor, a return conductor and a shunt capacitance unit that is coupled between the power supply conductor and the return conductor; andadjusting a voltage level of the DC power signal that is output from the power supply so that the DC power signal that is delivered to the remote radio head has a substantially constant voltage notwithstanding variation in a current level of the DC power signal that is output from the power supply. - View Dependent Claims (12, 13, 14, 15)
