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.
Claims19
An apparatus configured to provide direct current (DC) power, through a wiring connection and a DC-DC buck converter, to a radio of a cellular base station, the apparatus comprising:
- a first DC power supply comprising a power supply output electrically coupled through the wiring connection to the DC-DC buck converter configured to provide, at a converter output of the DC-DC buck converter and to a DC power input of the radio of the cellular base station, a first DC voltage that is less than or equal to a maximum DC voltage rating of the radio;
- wherein the first DC power supply is configured to provide a second DC voltage at the power supply output that is greater than the maximum DC voltage rating of the radio of the cellular base station.
A method for providing direct current (DC) electrical power, through electrical conductors and a DC-DC buck converter, to a radio of a cellular base station, the method comprising:
- generating a first DC power signal;
- and
- providing, at a power supply output, the first DC power signal having a first DC voltage that is greater than a recommended maximum DC voltage of the radio of the cellular base station, wherein the power supply output is configured to be electrically coupled through the electrical conductors to the DC-DC buck converter which is configured to provide, at a converter output of the DC-DC buck converter and to a DC power input of the radio of the cellular base station, a second DC voltage that is less than or equal to the recommended maximum DC voltage of the radio of the cellular base station.
