Abstract: A method and apparatus for authenticating a wireless connection between a first device and a second device. In a first aspect, the first device generates a changing passkey code and converts the passkey code to an audio file that is played through a speaker of the first device as an audible signal. A user hears the audible signal and enters the passkey code into a keyboard of the second device. The second device sends the entered code to the first device for authentication. In a second aspect, the first device generates a passkey code and displays the code on a screen. A user speaks the code aloud to a microphone on the second device. The second device converts the speech into text and then sends the converted speech to the first device for authentication. If the codes of the first or second aspect match, the wireless connection is authenticated.

Abstract: Methods and apparatus for determining device location in crowded indoor environments. A mobile device is configured to determine its location using a Wi-Fi Time of Flight (ToF)-based location scheme. Once the device determines it location, it may broadcast its location to nearby devices using a low energy location sharing mechanism that employs low energy broadcast signals identifying the location of the device. The low energy broadcast signals may be used by other devices having a similar configuration, as well as devices that don't use the ToF-based location scheme to determine their locations using RSSI measurements and multi-lateration and/or have such capabilities disabled. The location of a device may be updated by fusing location data derived from the ToF-based location scheme with location data received from nearby devices that are broadcasting their locations using the low energy location sharing mechanism.

Abstract: Techniques for obtaining device location using a BLE location beacon are provided. Specifically, methods are presented, that when taken alone or together, provide a device or group of devices with an efficient, low power means for obtaining a proximate location using a universally unique identifier.
