Abstract

A beam shaping antenna matrix for use in wireless cell towers that is manually-configured at a patch panel by a wireless operator based on selection of a desired beam size and point of direction. The traffic matrix allows a wireless operator to sculpt and resculpt the beams to accommodate demographic or other changes preferably without a large amount of hardware or intensive processing capability.

Claims

1. A beam shaping antenna matrix for use in wireless cell towers having a plurality of antenna panels mounted on a tower and each incorporating at least one antenna, a Butler matrix, and antenna and phasing lines connecting each said antenna panel to said Butler matrix, and a plurality of transceivers located in a tower base and each having an output and two inputs, the antenna matrix comprising a patch panel located in said tower base and having manual connection means at the face thereof for electrically connecting said transceiver inputs and outputs to any of the plurality of antenna panels to adaptively form antenna beams having defined and reconfigurable attributes, said manual connection means being operable by an operator in said tower base from the face of said patch panel to sculpt the beams of said antenna panels to accommodate demographic or other changes.

2. The beam shaping antenna matrix of claim 1, wherein said manual connection means further comprise a plurality of panel-mounted coaxial connectors and a plurality of open slots and corresponding personality modules for insertion into said slots to sculpt the beams of said antenna panels to accommodate demographic or other changes.

3. A beam shaping antenna matrix for use in wireless cell towers having a plurality of antenna panels each incorporating at least one antenna mounted on a cell tower, a Butler matrix, and antenna and phasing lines connecting each said antenna panel to said Butler matrix, and a plurality of transceivers each having receive inputs and transmit outputs, said beam shaping matrix comprising:

a component cabinet located in a control room of a cell tower and housing a plurality of modules for facilitating manual operator-connection of said antennas to said transceivers, said modules further comprising a first type of module having a plurality of panel-mount coaxial connectors for patch-panel coaxial cable connection, and a second type of module having a plurality of open bays for insertion of corresponding personality modules for plug-in interconnection.

4. The beam shaping antenna matrix according to claim 3, wherein said modules are grouped at the face of said component cabinet into a receive area and transmit area.

5. The beam shaping antenna matrix according to claim 4, wherein the modules in said receive area bear a plurality of panel-mount sector receive connectors.

6. The beam shaping antenna matrix according to claim 5, wherein said sector receive connectors further comprise two sets of receive inputs for each antenna panel.

7. The beam shaping antenna matrix according to claim 5, wherein the modules in said receive area bear a plurality of panel-mount Rx out connectors for each antenna.

8. The beam shaping antenna matrix according to claim 7, comprising a single Rx out connector corresponding to each of said antenna panels.

9. The beam shaping antenna matrix according to claim 7, wherein said Rx out connectors are connected to said antenna panels through a duplexer and low noise amplifier.

10. The beam shaping antenna matrix according to claim 7, further comprising a plurality of length-calibrated patch cords for connecting the sector receive connectors to corresponding Rx out connectors in order to selectively connect the antennas to corresponding transceivers, thereby allowing manual sculpting of the beams from the transceiver'"'"'s as desired across the antennas to accommodate demographic or other changes.

11. The beam shaping antenna matrix according to claim 4, wherein the transmit area comprises a transceiver panel having a panel-mounted coaxial panel connector for each antenna panel.

12. The beam shaping antenna matrix according to claim 11, further comprising a transmit beam former panel having a plurality of open bays each adapted to receive a corresponding personality module.

13. The beam shaping antenna matrix according to claim 12, wherein each personality module includes a plurality of output coaxial connectors to branch the transmit inputs Tx out to the antennas.

14. The beam shaping antenna matrix according to claim 11, wherein each personality module includes one input coaxial connector for connection by calibrated coaxial cable to a corresponding panel connector of the transceiver panel.

15. The beam shaping antenna matrix according to claim 14, wherein the transmit area allows simple assignment from the face of the matrix of any number of antennas to any one transceiver.

16. A method of beam shaping, comprising the steps of:

placing a manual connection matrix in the control room of a wireless towel for access by a wireless operator;

allowing said operator to selectively mechanically and electrically connect any transceiver in said tower to any of a plurality of antennas in any of a plurality of antenna panels using calibrated coaxial cables to adaptively form antenna beams having desired and reconfigurable attributes.

17. A method of beam shaping, comprising the steps of:

placing a manual connection matrix in the control room of a wireless tower for access by a wireless operator;

allowing said operator to mechanically and electrically connect any transceiver in said tower to any of a plurality of antennas in any of a plurality of antenna panels using plug-in personality modules to adaptively form antenna beams having desired and reconfigurable attributes.
