Abstract

A method performed at a cell site with an Unmanned Aerial Vehicle (UAV) communicatively coupled to a controller to perform a cell site audit, without requiring a tower climb at the cell site, includes causing the UAV to fly substantially vertically up to cell site components using the controller, wherein flight of the UAV is constrained in a three-dimensional rectangle at the cell site; collecting data associated with the cell site components and the surrounding airspace and environment using the UAV; transmitting and/or storing the collected data; and processing the collected data to obtain information for the cell site audit.

Claims

1. A method performed at a cell site with an Unmanned Aerial Vehicle (UAV) communicatively coupled to a controller to perform a cell site audit, without requiring a tower climb at the cell site, the method comprising:

causing the UAV to fly substantially vertically up to cell site components using the controller, wherein flight of the UAV is constrained to fly vertically in a three-dimensional rectangle at the cell site;

collecting data associated with the cell site components and the surrounding airspace and environment using the UAV;

transmitting and/or storing the collected data; and

processing the collected data to obtain information for the cell site audit, wherein the processing comprises determining a down tilt angle of one or more antennas of the cell site components, plumb of the tower and/or the one or more antennas, azimuth of the one or more antennas, and Global Positioning Satellite (GPS) coordinates, for the cell site audit.

2. The method of claim 1, wherein the cell site audit is performed by one of i) a single operator flying the UAV without a license or ii) two operators including one with a license and one to spot the UAV.

3. The method of claim 1, further comprising:

performing one or more aspects of the cell site audit without the UAV at least a portion of which are in a shelter or cabinet located proximate to a cell tower; and

utilizing the UAV to perform one or more aspects of the cell site audit that would require the tower climb.

4. The method of claim 1, further comprising:

flying the UAV to another cell site, wherein, once at the another cell site, flight of the UAV is constrained in a three-dimensional rectangle at the another cell site.

5. The method of claim 1, wherein the determining further comprises ensuring the down tilt angle and the azimuth are within a tolerance based on previous data collected on a Radio Frequency (RF) data sheet for the cell site.

6. The method of claim 1, wherein an operator operates the UAV through a mobile device to perform various aspects of the cell site audit on the cell site components, the UAV comprising a camera broadcasting to the mobile device, providing a real-time view to the operator.

7. The method of claim 1, wherein the UAV comprises one or more antennas configured to provide wireless service, and the method further comprising:

hovering the UAV at the cell site to provide the wireless service, wherein the wireless service is provided through one of licensed or unlicensed spectrum.

8. The method of claim 1, further comprising:

utilizing the UAV to attach or detach one or more components associated with the cell site components.

9. The method of claim 1, further comprising:

hovering the UAV at the cell site to provide real-time video footage back to a mobile device or another location.

10. An Unmanned Aerial Vehicle (UAV) configured to perform a cell site audit at a cell site, without requiring a tower climb at the cell site, the UAV comprising:

one or more rotors disposed to a body;

a camera associated with the body;

wireless interfaces;

a processor coupled to the wireless interfaces; and

memory storing instructions that, when executed, cause the processor to;

receive instructions, via the wireless interfaces, related to flight at the cell site, wherein flight of the UAV is constrained to fly vertically in a three-dimensional rectangle at the cell site;

cause the one or more rotors to operate pursuant to the instructions;

operate the camera pursuant to the instructions; and

transmit, via the wireless interfaces, or store, in a data store, data from the camera, for performing the cell site audit, wherein the data is processed to obtain information for the cell site audit, wherein the information comprises a down tilt angle of one or more antennas of the cell site components, plumb of the tower and/or the one or more antennas, azimuth of the one or more antennas, and Global Positioning Satellite (GPS) coordinates, for the cell site audit.

11. The UAV of claim 10, wherein the cell site audit is performed by one of i) a single operator flying the UAV without a license or ii) two operators including one with a license and one to spot the UAV

12. The UAV of claim 10, wherein one or more aspects of the cell site audit are performed without the UAV at least a portion of which are in a shelter or cabinet located proximate to a cell tower, and wherein the UAV is utilized to perform one or more aspects of the cell site audit that would require the tower climb.

13. The UAV of claim 10, wherein the UAV is flown to another cell site, and, once at the another cell site, flight of the UAV is constrained in a three-dimensional rectangle at the another cell site.

14. The UAV of claim 10, wherein the information is used to ensure the down tilt angle and the azimuth are within a tolerance based on previous data collected on a Radio Frequency (RF) data sheet for the cell site.

15. The UAV of claim 10, wherein an operator operates the UAV through a mobile device to perform various aspects of the cell site audit on the cell site components, the camera broadcasting to the mobile device providing a real-time view to the operator.

16. The UAV of claim 10, wherein the UAV comprises one or more antennas configured to provide wireless service, wherein the UAV is configured to hover at the cell site to provide the wireless service, wherein the wireless service is provided through one of licensed or unlicensed spectrum.

17. The UAV of claim 10, wherein the UAV is utilized to attach or detach one or more components associated with the cell site components.

18. The UAV of claim 10, wherein the UAV is configured to hover at the cell site to provide real-time video footage back to a mobile device or another location.

19. A system configured to perform a cell site audit at a cell site, without requiring a tower climb at the cell site, the system comprising:

a mobile device comprising;

mobile device wireless interfaces communicatively coupled to wireless interfaces on an Unmanned Aerial Vehicle (UAV);

a display;

a processor, wherein the mobile device wireless interfaces, the display, and the processor are communicatively coupled to one another; and

memory storing instructions that, when executed, cause the processor to;

cause the UAV to fly substantially vertically up to cell site components through communication to the UAV wireless interfaces, wherein flight of the UAV is constrained to fly vertically in a three-dimensional rectangle at the cell site;

receive data associated with the cell site components from the UAV wireless interfaces;

display the received data to the display; and

process the received data to obtain information for the cell site audit, wherein the information comprises a down tilt angle of one or more antennas of the cell site components, plumb of the tower and/or the one or more antennas, azimuth of the one or more antennas, and Global Positioning Satellite (GPS) coordinates, for the cell site audit.

20. The system of claim 19, wherein the cell site audit is performed by one of i) a single operator flying the UAV without a license or ii) two operators including one with a license and one to spot the UAV.
