Abstract
Methods of powering a radio that is mounted on a tower of a cellular base station are provided in which a direct current (“DC”) power signal is provided to the radio over a power cable and a voltage level of the output of the power supply is adjusted so as to provide a substantially constant voltage at a first end of the power cable that is remote from the power supply. Related cellular base stations and programmable power supplies are also provided.
Claims11
An apparatus configured to provide direct current (DC) power to a radio of a cellular base station through electrical conductors including first ends and radio ends, the apparatus comprising:
- a DC power supply comprising an output configured to provide a DC power signal from the first ends to the radio ends which are configured to be electrically coupled to the radio of the cellular base station;
- and
- wherein the DC power supply is configured to adjust a first DC voltage level, of the DC power signal, at the output responsive to a value of a parameter of a system including the DC power supply and the electrical conductors;
- wherein the DC power supply is further configured to provide a second DC voltage level, of the DC power signal and at the radio ends, that exceeds a nominal DC voltage rating of the radio of the cellular base station.
