Disclosed are various embodiments of a wireless access point. An 802.11 probe request frame is obtained from a wireless device in a wireless access point. Identifying information about the wireless device is extracted from the 802.11 probe request frame. The identifying information and an access point identifier corresponding to the wireless access point to at least one server via a network, from which location and/or proximity to the wireless access point can be determined.

Proximity detection

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.
