US Patent 9730255 Room-specific pairing via a combined ultrasonic beacon/bluetooth approach

Embodiments disclosed describe room specific pairing of electronic devices using the combination of ultrasonic signal and other wireless means such as Bluetooth. The ultrasonic signal is used to communicate a unique identifier to the electronic devices within the same physical location. The electronic device receiving the ultrasonic signal uses the unique identifier to establish a secure wireless communication with the base station. The wireless communication is then used to communication the configuration information for a second network connection between the base station and the electronic device.
