METHODS AND EQUIPMENT FOR REDUCING POWER LOSS IN CELLULAR SYSTEMS

摘要

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.

主权项

1. A method of determining a resistance of a power cabling connection between a power supply and a remote radio head, the method comprising:
outputting a first direct current (“DC”) power signal having a first voltage level from the power supply onto the power cabling connection; measuring a first current level of the first DC power signal; outputting a second DC power signal having a second voltage level that is different than the first voltage level from the power supply onto the power cabling connection; measuring a second current level of the second DC power signal; and determining a resistance of the power cabling connection based at least in part on the first and second voltage levels and the first and second current levels.
