Abstract

A site survey device including a location sensor and a processor coupled to the location sensor. The processor acquires location information from the location sensor and determines reception data relating to a signal received from a wireless device to identify a location wherein the reception data is determined. The location sensor may include an electronic compass to produce electrical signals corresponding to a heading of a surveyor and an inertial sensor to produce electrical signals corresponding to a magnitude of a change in location. The location information may be determined as a change in location. In operation, a plurality of location information may be acquired together with corresponding reception data from a wireless infrastructure. The device may indicate each of the plurality of location information and corresponding reception data on an electronic indication of a site map.

Claims

1. A site survey device configured to assist a surveyor during a site survey of a wireless infrastructure, the device comprising:

a location sensor;

and a processor operationally coupled to the location sensor, wherein the processor is configured to acquire location information from the location sensor, is configured to determine reception data relating to a signal received from a wireless device, and thereby identify a location wherein the reception data is determined.

2. The device of claim 1, wherein the location sensor comprises:

an electronic compass configured to produce electrical signals corresponding to a heading of the surveyor; and

an inertial sensor configured to produce electrical signals corresponding to a magnitude of a change in location, wherein the location information is a change in location from a first location to the location where the location information is acquired as determined by the electronic compass and the inertial sensor.

3. The device of claim 2, wherein the location sensor comprises a GPS configured to produce calibration data to calibrate the electronic compass to true-north.

4. The device of claim 1, wherein the location information is one of a plurality of location information, wherein the location sensor is configured to determine each of the plurality of location information and the processor is configured to determine reception data relating to each of the plurality of location information and indicate each of the plurality of location information and corresponding reception data on an electronic indication of a site map.

5. The device of claim 1, wherein the location sensor is configured to acquire correction data and wherein the processor is configured to receive the correcting data for correcting determined location information.

6. The device of claim 4, wherein the location sensor comprises at least one of a camera, a ranging sensor, and a GPS for acquiring the correction data.

7. The device of claim 4, wherein the location sensor comprises the camera which operates as a portion of a head-mounted imaging system configured to detect an object at the survey site that has a known position.

8. A method of performing a site survey of a wireless infrastructure, the method comprising the acts of:

acquiring location information from an electronic location sensor;

determining reception data related to a quality of a received signal from the wireless infrastructure at the location where the location information is acquired.

9. The method of claim 8, wherein acquiring location information comprises the acts of:

receiving heading data corresponding to a heading of a surveyor from a first location to the location wherein the location information is acquired; and

determining inertial data corresponding to a magnitude of a change in location from the first location to the location wherein the location information is acquired.

10. The method of claim 9, the method comprising the act of calibrating the heading data to true-north.

11. The method of claim 8, comprising the acts of:

acquiring a plurality of location information as a change in location from a previous location; and

determining a corresponding plurality of reception data.

12. The method of claim 8, wherein the location information is a change in location from a first location to the location where the location information is acquired, the method comprising the acts of:

acquiring electronic correction data; and

correcting the location information.

13. The method of claim 12, wherein acquiring the correction data comprises the acts of:

identifying a known position; and

determining the location where the location information is acquired from the known position.

14. An application embodied on a computer readable medium configured to aid in a site survey of a wireless infrastructure, the application comprising:

a portion configured to acquire location information from an electronic location sensor;

a portion configured to determine reception data related to a quality of a received signal from the wireless infrastructure at the location where the location information is acquired.

15. The application of claim 14, wherein the portion configured to acquire location information is configured to:

receive heading data corresponding to a heading of a surveyor from a first location to the location wherein the location information is acquired; and

determine inertial data corresponding to a magnitude of a change in location from the first location to the location wherein the location information is acquired.

16. The application of claim 14, comprising a portion configured to correct the location information.

17. A site survey device to assist a surveyor during a site survey of a wireless infrastructure, the device comprising:

a means for acquiring location information from an electronic location sensor;

a means for determining reception data related to a quality of a received signal from the wireless infrastructure at the location where the location information is acquired.

18. The device of claim 17, wherein the means for acquiring location information comprises:

a means for receiving heading data corresponding to a heading of a surveyor from a first location to the location wherein the location information is acquired; and

a means for determining inertial data corresponding to a magnitude of a change in location from the first location to the location wherein the location information is acquired.

19. The device of claim 18, comprising a means for calibrating the heading data to true-north.

20. The device of claim 17, comprising:

a means for acquiring electronic correction data; and

a means for correcting the location information.
