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.
Claims18
An apparatus configured to be electrically coupled to a direct current (DC) power input of a radio and to a first DC-DC voltage converter, the apparatus comprising:
- a second DC-DC voltage converter including a first input, a second input, and an output;
- and
- wherein the first input is configured to receive a first DC power from the first DC-DC voltage converter;
- wherein the output is configured to be electrically coupled and provide a second DC power to the DC power input of the radio;
- wherein the second input is configured to receive parameter data about the radio;
- wherein the second DC-DC voltage converter is configured to provide, at the output, a first DC voltage level determined with use of the parameter data and to provide, at the DC power input of the radio, a second DC voltage level that exceeds a nominal DC input voltage rating of the radio.
A method for setting a first DC voltage level of a first direct current (DC) power, the method comprising:
- receiving, at a first input of a first DC-DC voltage converter, a second DC power from a second DC-DC voltage converter;
- providing first DC power, at an output of the first DC-DC voltage converter, to a DC power input of a radio;
- receiving, at a second input of the first DC-DC voltage converter, parameter data of the radio;
- and
- providing the first DC voltage level of the first DC power, at the output, using of the parameter data, and further providing a second DC voltage level at the DC power input of the radio that exceeds a nominal DC input voltage level, of the radio, at which the radio is recommended to operate.
