Abstract

Disclosed is a power distribution system for powering a plurality of remote radio heads mounted on the top of a cell tower. The distribution system includes a plurality of bulk power inputs, each of which is coupled to a row of power input sockets, and a plurality of breaker input socket rows. The power input socket rows and breaker input socket rows are arranged such that they are evenly spaced and the sockets are in columns. The system includes a plurality of jumpers that are designed to be installed such that multiple combinations of connections between bulk power inputs and circuit breaker inputs such that the system can be easily reconfigured.

First claim

What is claimed is:

1 . A power distribution system for powering a plurality of remote radio units in a wireless telecommunications system, comprising:
a plurality of bulk power inputs; a plurality of power input socket rows, each of the plurality of power input socket rows coupled to a corresponding bulk power input, each of the plurality of power input socket rows having a plurality of power input sockets arranged along an x-axis and coupled together by a bus bar, wherein the plurality of power input socket rows are arranged whereby the plurality of power input sockets are arranged in columns along the x-axis, and whereby the plurality of power input socket rows is divided into a first subset of power input socket rows having a first number of rows and a second subset of power input socket rows having a second number of rows; a plurality of breaker input socket rows having a third number of rows, each of the plurality of breaker input socket rows having a plurality of breaker input sockets arranged along the x-axis whereby they are aligned along the x-axis with a corresponding power input socket within each of the plurality of power input socket rows, wherein each of the plurality of breaker input sockets is a given column are coupled together and coupled to a corresponding circuit breaker input; a plurality of circuit breakers, each of the plurality of circuit breakers coupled to a corresponding circuit breaker input, and each of the plurality of circuit breakers having a circuit breaker output, wherein each circuit breaker output is configured to be coupled to a corresponding remote radio unit via a conductor cable; and a plurality of jumpers configured to couple a source power input socket within the plurality of power input socket rows to a corresponding breaker input socket, each of the plurality of jumpers having a jumper length, wherein the plurality of breaker input socket rows are disposed between the first subset of power input socket rows and the second subset of power input socket rows, and wherein the first number of rows and the second number of rows are not greater than the third number of rows, wherein the plurality of power input socket rows and breaker input socket rows are spaced along a y-axis by a row spacing, and wherein the jumper length corresponds to the row spacing multiplied by the third number of rows.

2 . The system of claim 1 , wherein the third number of rows equals two.

3 . The system of claim 1 , wherein the third number of rows equals three.

4 . The system of claim 1 , wherein each of the plurality of power input socket rows comprises eight power input sockets.

5 . The system of claim 1 , wherein the row spacing is 1.2″.

6 . A method for configuring a power distribution system for a plurality of remote radio units, the method comprising:
determining a required power for each of a plurality of remote radio units; determining an available power from each of a plurality of bulk power inputs; identifying a power allocation between the plurality of bulk power inputs and the plurality of remote radio units; and installing a plurality of jumpers between a plurality of power input socket rows and a plurality of breaker input socket rows, wherein each of the plurality of power input socket rows is coupled to a corresponding bulk power input, wherein each of the plurality of jumpers couples one of the plurality of bulk power inputs to one of the plurality of remote radio units according to the power allocation.
