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.
