Abstract
In one embodiment, a method includes receiving a sonic signal from a beacon device at a mobile device, receiving a wireless signal from the beacon device at the mobile device, detecting a presence of an enclosure surrounding the beacon device by the mobile device based on a disparity between a normalized strength of the sonic signal and a normalized strength of the wireless signal, and determining whether the detected enclosure complies with installation guidelines associated with the beacon device by the mobile device.
