Abstract

An electronic switching device connected between a base station antenna tower and the base station electronics allows an operator to selectably connect external equipment, such as a Cell-On-Wheels (COW).

Claims

1. A method for selectably connecting an external device at a cell site, comprising the steps of:

connecting each of a plurality of first terminals a switching device disposed at a cell site to a cell site antenna;

connecting each of a plurality of second terminals of the switching device to cell site electronics;

connecting of a plurality of third terminals of the switching device to an external cell site maintenance device; and

setting each of a plurality of antenna switches to a selected one of at least two antenna states, in a first antenna state a first terminal connected to a second terminal, and in a second antenna state a first terminal connected to a third terminal.

2. The method claimed in claim 1, wherein the setting step comprises setting an electronically-controlled switch in response to input provided by an operator on a control panel.

3. The method claimed in claim 2, wherein the control panel receives the input via a keypad.

4. The method claimed in claim 3, further comprising the step of decoding the input to determine which of the plurality of antenna switches to set to the first state and which of the plurality of antenna switches to set to the second state.

5. The method claimed in claim 3, further comprising the step of enabling the setting step in response to an authorized security code provided by an operator via the keypad.

6. The method claimed in claim 1, wherein each of the connecting steps comprises connecting a coaxial cable connector.

7. The method claimed in claim 1, further comprising the step of setting each of a plurality of load switches to a selected one of at least two load states, in a first one of the load states a second terminal is connected to an antenna switch, and in a second one of the states the second terminal is connected to a dummy load and not to an antenna switch.

8. The method claimed in claim 1, wherein the step of connecting each of a plurality of third terminals to an external cell site maintenance device comprises connecting each third terminal to a Cell On Wheels.

9. A method for retrofitting a cell site base station with a switching device, comprising the steps of:

disposing the switching device at a cell site, the switching device comprising an enclosure, a plurality of first terminals on the enclosure, a corresponding plurality of second terminals on the enclosure, a corresponding plurality of third terminals on the enclosure, a corresponding plurality of electronically-controlled antenna switches within the enclosure, and an operator control panel, each antenna switch having at least two operator-selectable antenna states selectable via the control panel, in a first one of the antenna states a first terminal connected to a second terminal, and in a second one of the antenna states a first terminal connected to a third terminal;

connecting each first terminal to a cell site antenna; and

connecting each second terminal to cell site electronics.

10. A switching apparatus for a cell site base station, comprising:

an enclosure;

a plurality of first terminals on the enclosure;

a plurality of second terminals on the enclosure, each second terminal corresponding to a first terminal;

a plurality of third terminals on the enclosure, each third terminal corresponding to a first terminal and a second terminal;

a plurality of electronically-controlled antenna switches within the enclosure, each antenna switch corresponding to a first terminal, a second terminal and a third terminal; and

an operator control panel, each antenna switch having at least two operator-selectable antenna states selectable via the control panel, in a first one of the antenna states a first terminal connected to a second terminal, and in a second one of the antenna states a first terminal connected to a third terminal.

11. The system claimed in claim 10, further comprising a plurality of electronically-controlled load switches within the enclosure, each load switch corresponding to a second terminal and having at least two operator-selectable load states selectable via the control panel, in a first one of the load states a second terminal is connected to an antenna switch, and in a second one of the load states the second terminal is connected to a dummy load.

12. The system claimed in claim 10, wherein the first, second and third terminals include ground conductors connected to each other in the enclosure and connected to the enclosure.
