Location Accuracy

Location Accuracy

You can perform a location accuracy test for a single device with multiple location points. You can use the Location Accuracy Test tool to validate the placement and number of access points (APs), for a good location accuracy experience. The Location Accuracy tool provides you with the ability to quantify the location accuracy for a specific location. During the Location Accuracy test, the administrator uses a wireless client device to measure the difference between the actual and the calculated location of a device.

Restrictions for Location Accuracy

  • The display refresh time is three seconds and cannot be reconfigured.

  • You cannot run this location accuracy test on APs with external antennas. However, location detection is supported on these APs.

  • You cannot reconfigure the display refresh time. The display refresh time is three seconds.

  • The sample count displayed during a location accuracy test is a best-effort estimate of location values collected during back end processes. This sample count may differ from actual samples captured during an accuracy test.

Test Location Accuracy

This Cisco Spaces: Detect and Locate shows you how to run the location accuracy test.

Procedure

Step 1

From the Detect and Locate dashboard, search for a device using a MAC address from the Search MAC, IP, SSID, Manufacturer text field.

Figure 1. Detect and Locate: Dashboard

Step 2

Ensure that the Status of the device is ASSOCIATED and the Source is COMPUTE.

Step 3

In the device details window, click Accuracy Test tab.

Step 4

Enter a unique report name. Move the blue pointer to the client's real-time location or adjust the X and Y coordinates. To begin, click Start Test.

You can observe that the number of samples begins to increase.

Note

 

The display refresh time is three seconds.

Step 5

Wait for the number of samples to reach 20 and click Stop Test. Move the blue pointer representing the data point to a new location and click Start Test again.

Step 6

Repeat for multiple locations for a more accurate understanding of location accuracy.

Step 7

Repeat for multiple locations for a more accurate understanding of location accuracy.
