Abstract

Methods of operating a cellular radio are provided in which a first power supply signal is transmitted from a power supply to a wireless power unit at least in part over a power cable. A second power supply signal is wirelessly transmitted from the wireless power unit to the cellular radio to power the cellular radio. Data is transmitted from a baseband unit that is associated with the cellular radio to a wireless transceiver at least in part over a data cable. This data is wirelessly transmitted from the wireless transceiver to the cellular radio. The data is then transmitted through an antenna that is coupled to the cellular radio.

Claims

1. A method of operating a cellular radio that is remote from an associated baseband unit, the method comprising:

transmitting a first power supply signal from a power supply to a wireless power unit at least in part over a power cable;

wirelessly transmitting a second power supply signal from the wireless power unit to the cellular radio to power the cellular radio;

transmitting data from the associated baseband unit to a wireless transceiver at least in part over a data cable;

wirelessly transmitting the data from the wireless transceiver to the cellular radio; and

transmitting the data through an antenna that is coupled to the cellular radio.

2. The method of claim 1, wherein the wireless power unit is part of a trunk cable that includes the power cable and the data cable, and wherein the cellular radio is a remote radio head.

3. The method of claim 2, wherein the wireless power unit is part of a first cable termination that receives a first end of the trunk cable.

4. The method of claim 3, wherein the first cable termination includes a buck converter that reduces an average voltage of the first power supply signal.

5. The method of claim 4, further comprising a second cable termination that receives a second end of the trunk cable, the second cable termination including a boost converter that increases an average voltage of the first power supply signal.

6. The method of claim 5, wherein the trunk cable and the first and second cable terminations together form a sealed trunk cable assembly that cannot be opened in the field.

7. The method of claim 3, wherein the wireless transceiver comprises an 802.11 transceiver, and wherein the first cable termination is positioned adjacent the cellular radio near the top of a tower.

8. The method of claim 3, wherein the first cable termination includes a flexible extension, and wherein the wireless power unit is within the flexible extension.

9. The method of claim 3, wherein the wireless power unit comprises an electromagnetic induction unit, and wherein the first cable termination is positioned adjacent the cellular radio near the top of a tower.

10. The method of claim 3, wherein the data cable comprises a fiber optic data cable, and wherein the first cable termination includes an optical-to-electrical converter that converts an optical data signal into an electrical signal that is provided to the wireless transceiver.

11. The method of claim 1, further comprising wirelessly transmitting control signals to an antenna line device that is adjacent the cellular radio.

12. The method of claim 11, further comprising wirelessly providing a power supply signal to the antenna line device.

13. The method of claim 11, wherein the cellular radio and the antenna line device are located on a tower, wherein an antenna line device controller is located at the bottom of the tower and wirelessly transmit the control signals to the top of the tower, and wherein the antenna line device is powered at least in part by power from solar cells.

14. A trunk cable assembly for a cellular base station, comprising:
