I recently installed a building with an RTLS design, along with Hyperlocation modules installed. The customer was looking to get 1-3m accuracy for associated devices. This building is a walled office, and Cisco Best practices for Hyperlocation state that the hyperlocation APs need line of sight between them which we don’t have in this building.
I marked out on a map a number of locations to take location accuracy tests from:
I then used Cisco CMX to perform a location accuracy test:
The tests were conducted using a MacBook Air and a Samsung Galaxy S6 Edge.
Caveat: In order to speed up the location sample collections inSSIDer was ran on both the devices to speed up the number of probes sent which CMX uses for location calculations.
In my opinion for the additional costs involved to install Hyperlocation within a “walled office” environment I can not see the ROI benefits. Until I repeat this test in a “open planned” environment the jury is still out in whether Hyperlocation gives any huge benefits over a traditional RSSI location service.
That being said one benefit that Hyperlocation did give was that the location accuracy was more correct more of the time compared to the RSSI location calculations.
