Briefly, in accordance with one implementation, a method may include extracting, at a mobile device, visual features from one or more images captured via a camera sensor of the mobile device; and estimating a location of the mobile device based, at least in part, on a match between extracted visual features and one or more brand-specific visual signatures associated with one or more points of interest of one or more known locations. In some instances, an estimated location of a mobile device may be refined based, at least in part, on at least one additional POI of one or more POIs of one or more known locations.

摘要： Methods and apparatuses are provided that facilitate providing an object-based transport protocol that allows transmission of arbitrarily sized objects over a network protocol layer. The object-based transport protocol can also provide association of metadata with the objects to control communication thereof, and/or communication of response objects. Moreover, the object-based transport protocol can maintain sessions with remote network nodes that can include multiple channels, which can be updated over time to seamlessly provide mobility, increased data rates, and/or the like. In addition, properties can be modified remotely by network nodes receiving objects related to the properties.

摘要： The subject matter disclosed herein relates to systems, methods, apparatuses, devices, articles, and means for updating radio models. For certain example implementations, a method for one or more server devices may comprise receiving at one or more communication interfaces at least one measurement that corresponds to a position of a first mobile device within an indoor environment. At least one radio model that is stored in one or more memories may be updated based, at least in part, on the at least one measurement to produce at least one updated radio model. The at least one radio model and the at least one updated radio model may correspond to the indoor environment. The at least one updated radio model may be transmitted to enable a second mobile device to use the at least one updated radio model for positioning within the indoor environment. Other example implementations are described herein.
