Abstract: In one embodiment, an integrated power cable is provided. The integrated power cable, comprises a power cable having a first end and a second end; wherein the first end is configured to be electrically coupled to a DC power supply; at least one DC-DC voltage converter having at least one input and at least one output; wherein the second end is fixedly electrically and mechanically connected to the input; a first connector fixedly connected mechanically and electrically to the output; and wherein the first connector is configured to be coupled to at least one remote radio head.

Abstract: A method is provided. The method comprises: booting a system; determining if the system has properly booted; if the system has properly booted, then initiating communications with the at least one DC-DC voltage converter system that is configured to power at least one remote radio head; determining if communications have been established with the at least one DC-DC voltage converter system; and if communications have been established, then supplying a higher voltage from the system.

Abstract: In one embodiment, a method is provided. The method comprises: setting a first voltage level provided to a cable; operating a radio, coupled to the cable, with constant power consumption; measuring a first current level provided to the cable; setting a second voltage level provided to the cable; measuring a second current level provided to the cable; and determining a first resistance of the cable using the first and second voltage and current levels.

Abstract: A method is provided. The method comprises determining configuration data; wherein the configuration data comprises a resistance of a bypass circuit coupled between a remote radio head and a power cable; using the configuration data, determining the resistance of the power cable coupling a programmable power supply to the remote radio head mounted on a mounting structure, comprising: entering a calibration mode; setting an output voltage of the programmable power supply; measuring an output current of the programmable power supply; storing the output current; and determining the cable resistance; and storing the resistance of the power cable.

Abstract: System and method for implementing RMII Ethernet reset of a slave card is described. In one embodiment, the invention comprises a method of resetting a slave card electrically connected to an administrative processor of a system via a Reduced Media Independent Interface (“RMII”) Ethernet physical layer device (“PHY”). The method comprises, responsive to detection of a start of frame indicator (“SFI”), activating a shift register; shifting reset signal data into the shift register; comparing the reset signal data shifted into the shift register with compare data; and responsive to the reset signal data being the same as the compare data, resetting the slave card.
