XNZR is a personal WiFi Access Point direction finder on back of your mobile; powered by an AR GUI.
The direction finder can be manual or automatic. The automatic version doesn’t need to be moved in order to find the angle of arrival, however the hardware costs much more than the manual one. The manual device must be moved around in order for the target to find the angle. All modern mobile devices have a camera on the back. This helps to find a target using a Manual Direction Finder. Installation of a Manual Direction Finder on the back of a mobile device is extremely “organic”.
