Abstract

Wireless radio device alignment tools and methods. Described herein are methods for point-to-point alignment of wireless radio devices and alignment tools to assist in aligning wireless radio devices. These alignment tools may automatically or manually receive location information and may use a local compass function to determine a rough or initial alignment and additional tools to provide further (fine) alignment based on calculated and actual signal strength between the two devices being aligned.

Claims

1. A method for point-to-point alignment of wireless radio devices using an alignment tool having a compass, the method comprising:

determining a location of a first wireless radio device that is remotely located relative to the alignment tool;

determining a location of a second wireless radio device that is local to the alignment tool;

using the compass of the alignment tool and the locations of the first and second wireless radio devices to determine a direction to point the second wireless radio device; and

displaying, on the alignment tool, an indicator of the direction.

2. The method of claim 1, further comprising mounting the alignment tool onto the second radio device.

3. The method of claim 1, wherein determining the location of the first wireless radio device comprises entering the identity of the first wireless radio device into the alignment tool.

4. The method of claim 1, wherein determining the location of the first wireless radio device comprises entering the identity of the first wireless radio device into the alignment tool and receiving GPS information indicating the location of the first wireless radio device.

5. The method of claim 1, wherein determining the location of the first wireless radio device comprises wirelessly receiving, in the alignment tool, a GPS indication of the location of the first wireless radio device.

6. The method of claim 1, wherein determining the location of the second wireless radio device comprises determining the location of the alignment tool.

7. The method of claim 1, wherein determining the location of the second wireless radio device comprises receiving a GPS indication of the location of the second wireless radio device.

8. The method of claim 1, further comprising finely tuning the direction of the second radio device.

9. The method of claim 1, further comprising displaying with the alignment tool, an indicator of the measured signal strength between the first and second radio devices.

10. The method of claim 1, further comprising:

calculating an estimate of optimal signal strength between the first and second wireless radio devices; and

displaying on the alignment tool an indicator of the optimal signal strength between the first and second wireless radio devices.

11. The method of claim 1, further comprising:

calculating an estimate of optimal signal strength between the first and second wireless radio devices; and

displaying on the alignment tool an indicator of how optimal the signal strength between the first and second wireless radio devices is.

12. The method of claim 1, further comprising activating the alignment tool, wherein the alignment tool comprises a module attached to the second wireless radio device.

13. A method for point-to-point alignment of wireless radio devices using an alignment tool having a compass, the method comprising:

entering an identity of a first wireless radio device into the alignment tool, wherein the first wireless radio device is remotely located relative to the alignment tool;

determining a location of the first wireless radio device;

determining a location of a second wireless radio device that is local to the alignment tool;

calculating a direction of the first wireless radio device relative to the second wireless radio device; and

using the compass of the alignment tool to determine a direction to point the second wireless radio device so that the second wireless device is oriented towards the first wireless radio device; and

displaying, with the alignment tool, an indicator of the direction to point the second wireless radio device.

14. The method of claim 13, further comprising mounting the alignment tool onto the second radio device.

15. The method of claim 13 wherein calculating the direction of the first wireless radio device relative to the second wireless radio device comprises calculating the direction of the first wireless radio device relative to the second wireless radio device in the alignment tool.

16. The method of claim 13 wherein calculating the direction of the first wireless radio device relative to the second wireless radio device comprises calculating the direction of the first wireless radio device relative to the second wireless radio device in a remote processor and transmitting the direction to the alignment tool.

17. The method of claim 13, further comprising displaying with the alignment tool, an indicator of the measured signal strength between the first and second radio devices.

18. The method of claim 13, further comprising:

calculating an estimate of optimal signal strength between the first and second wireless radio devices; and

displaying on the alignment tool an indicator of the optimal signal strength between the first and second wireless radio devices.

19. The method of claim 13, further comprising:

calculating an estimate of optimal signal strength between the first and second wireless radio devices; and

displaying on the alignment tool an indicator of how optimal the signal strength between the first and second wireless radio devices is.

20. A method of aligning two wireless radio devices using an alignment tool, the method comprising:

rough aligning a first wireless radio device and a second wireless radio device by aiming the first wireless radio device at the second wireless radio device using an alignment tool on the first wireless radio device;

receiving an indicator of signal strength between the first and second wireless radio devices;

displaying the indicator of signal strength on the alignment tool; and

fine aligning the first wireless radio device and the second wireless radio device using the displayed indicator of signal strength on the alignment tool.
