Systems, methods, and non-transitory computer-readable media can provide an interface that includes a grid of content items, the grid also including at least a first slot through which a first content channel is accessible and a second slot through which a second content channel is accessible. A determination is made that the second content channel is ranked higher than the first content channel based at least in part on one or more measurements. The interface is updated so that the second content channel is presented in the first slot and the first content channel is presented in the second slot.

Systems and methods for ranking content

Methods, apparatuses, and devices are disclosed to estimate a position of a mobile device using, for example, beacon signals transmitted using virtual access points utilizing a single, physical transceiver. Determination that beacon signals emanate from a single, physical transceiver may be based, at least in part, on a similarity among acquired beacon signals conveying identifiers, such as media access control identification (MAC ID) addresses and/or basic service set identifiers (BSSIDs), and on measurement of beacon signal characteristics, such as received signal strength at a mobile device and/or round trip time between the mobile device and the transceiver.

Methods, apparatuses, and devices for mobile device position estimation using virtual access points

Methods and apparatus for processing positioning assistance data are provided. An exemplary method includes receiving, from a positioning server, virtual access point (VAP) data including a list of unique identifiers, and determining a location of a mobile device by using the VAP. The VAP data indicates that the unique identifiers included on the list identify signals originating from the same physical access point. The unique identifiers can be MAC addresses. In an example, the location determining the can include actively scanning a signal identified by a unique identifier on the list and not actively scanning a different signal identified by a different unique identifier also on the list. Not scanning the other MAC addresses that are on the access point's list and assigned to the mobile device keeps the mobile device from performing duplicative scanning that wastes time, processor cycles, and energy.

Method and apparatus for delivering assistance data from a server to a device identifying virtual access points

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.

Mobile device positioning based on independently obtained barometric pressure measurements

Disclosed are systems, methods and devices for providing positioning assistance data to a mobile device. In a particular implementation, a mobile device may receive parameters representing an inference model. The mobile device may then apply observations to the inference model to classify the location of the mobile device as being in a particular region. The mobile device may then request positioning assistance data based, at least in part, on the particular region.

System, method and devices for delivering positioning assistance data

Example methods, apparatuses, or articles of manufacture are disclosed herein that may be utilized, in whole or in part, to facilitate or support one or more operations or techniques for utilizing a pressure profile to determine a location context identifier (LCI) for use in or with a mobile communication device.
