    Abstract: Various techniques are provided which may be implemented as methods, apparatuses and articles of manufacture for use by a mobile device. In certain example implementations, a mobile device may process a barometric pressure measurement indicative of an altitude effect and a weather effect to determine a first parameter corresponding to the altitude effect and a second parameter corresponding to the weather. Such a mobile device may further determine whether it may be transitioning or may have transitioned from an initial level to another level of a multiple level structure based, at least in part, on the first and second parameters.

    Abstract: Systems, apparatus and methods for preparing assistance data in a location server from coverage report messages of one or more access points from a plurality of mobile devices are presented. Several mobile devices each collect information from and about one or more access points. This crowd-sourced information is sent from a mobile device to a location server and may include ranging information (such as RSSI or RTT) and/or broadcast information (such as broadcast position and/or transmit power level) and/or computed information (such as path loss). Using this crowd-sourced information, the location server may form assistance data for an assistance data database, which may later be tailored for and send to a specific mobile device.
