Hyperlocation / Halo Testing in my lab

Note: These results are by no means accurate or are meant to reflect actual production data. I don’t have my Maps in CMX fine tuned and same goes for the AP placement and orientation. This testing is only for my personal learning and know how of the technology.

So, lets get started, shall we?

below is the view of my Map area for testing. The ‘pink’ dots on the Map are all the detected clients (irrespective of wireless infrastructure they are associated to) and the ‘green’ dot shows the associated clients to one of the WLC mapped to CMX 10.2.1.

To run the location accuracy test you basically have to click on one of the clients you want to run the test on (click the green dot and it will show you information about the client like mac address, ip address etc). When you click on a client, it will also show an option to run the location test.

Click on begin location accuracy test, enter a name for the test, drag the blue location icon to where you think the client really is and run the test.

Please make sure you run the test for at least 2 mins (make sure the client is up and interacting with the network and does not go off to sleep during the test). Move the client to a different locations and run the same test (for 2 mins) at those locations. A good sample space is about 10-20 locations for accurate results.

During the test the client green dot may move a little bit on the map which is normal as you can see in the video below. You can also see my test results at the end of the video which is about 2.93m (please note this is just a test environment)

You can check the test results from the results page

Note: if you notice some tests show 0.0 values which means the test failed. This happened to me because my iPhone auto lock is set to 1 min and hence the phone would go off to sleep within the 2 mins test period where it needs to be active at all times. I learned this the hard way :).

Below is a small snippet from the detailed logs downloaded from CMX
