  "textContent": "An apparatus and method is provided for indoor/outdoor transition detection of devices to improve selection of the navigation algorithms. A mobile device can scan resources such as radio frequency (RF) sources in its vicinity and compare the scanned resources with a set of indoor-only resources to determine whether the mobile device is located inside a structure (e.g., indoor) or outside the structure (e.g., outdoor). The techniques provide an apparatus and method to determine when a device transitions between indoor and outdoor to efficiently use appropriate algorithm for positioning and/or navigation.",
