Abstract:
A method of predicting positioning performance of a set of N access points in an indoor region includes: obtaining a signal-strength map including signal-strength vectors and corresponding locations in the indoor region, the signal-strength vectors each including N signal-strength indications that each indicate an expected received signal strength from a corresponding one of the set of N access points; and determining a position uncertainty value using the signal-strength map, the position uncertainty value being indicative of a positioning accuracy at a corresponding point of interest in the indoor region.
Abstract:
Disclosed are systems, apparatus, devices, methods, computer program products, and other implementations, including a method of controlling navigation tasks on a mobile device that includes obtaining data representative of a route of travel for the mobile device, obtaining a list of navigation tasks associated with the route of travel for the mobile device, and performing one or more navigation tasks in accordance with the list of navigation tasks based, at least in part, on proximity of the mobile device to one or more points on the route of travel. Performing the one or more navigation tasks includes one or more of, for example, obtaining satellite positioning assistance data in response to a determination that the mobile device is transitioning from an indoor area to an outdoor area, and/or establishing a communication link with an access point.

Abstract:
A system includes: an interface; and a processor configured to: receive one or more search criteria from the interface, the one or more search criteria being a first portion of a search query; determine a second portion of the search query based on the first portion of the search query and an association of the first portion of the search query with an entity, the search query being a request for a location of a target device associated with the entity; cause a transceiver of the interface to transmit the search query wirelessly in one or more outbound electronic signals to a first intermediate device; receive one or more inbound electronic signals from the first intermediate device via the interface, the one or more inbound electronic signals including a location of the target device; and cause the interface to provide an indication of the location of the target device.
Abstract:
A method of operating a wireless device includes determining to operate the wireless device in a discontinuous reception (DRX) mode of operation such that a receiver of the wireless device is expected to operate in a low-power state during a scheduled low-power period of time and the receiver is expected to operate in an active-power state during a scheduled active-power period of time. The wireless device schedules a measurement of a positioning signal using the receiver. The measurement is scheduled to occur during a scheduled measurement period of time. The scheduled measurement period of time at least partially overlaps with at least one of the scheduled low-power period of time or the scheduled active-power period of time. The wireless device operates the wireless device in the DRX mode of operation after scheduling the measurement and before a start of the scheduled measurement period of time.
Abstract:
A method of locating a target device includes: producing, at a query device, a request for a location of a target device, the query device including a first radio, of a first type, configured to communicate wirelessly using a first communication protocol, the target lacking a radio of the first type but including a second radio, of a second type, configured to communicate wirelessly using a second communication protocol, the second communication protocol being incompatible with the first communication protocol; and transmitting the request wirelessly, from the query device to a first intermediate device, using the first radio.
Abstract:
A method of performing functions by proxy for a set of associated proximate devices is disclosed. In some embodiments, the method may comprise associating a set of user equipments (UEs), wherein upon determination that a first UE in the set is unavailable for performing a requested function, at least one alternate second UE in the associated set of UEs is selected, wherein the at least one second UE is proximate to the first UE and the at least one second UE is available for performing the requested function. The performance of the requested function on the at least one second UE is initiated.
Abstract:
Methods and systems for utilizing priority based geofences are disclosed. A mobile device receives, from another device over a wireless network, at least one geofence, each of the at least one geofence having an assigned priority level indicating an importance of the at least one geofence, wherein the assigned priority level is one of a plurality of priority levels and is received from the other device over the wireless network, determines, based on the priority level of the at least one geofence, a geofence breach detection method and an evaluation rate, and monitors a position of the mobile device relative to the at least one geofence at the evaluation rate using the geofence breach detection method.
Abstract:
Systems and methods for managing activities among two or more mobile devices that are collocated include means for determining a set of tasks to be performed collectively by at least a first mobile device comprising a first set of subsystems and a second mobile device comprising a second set of subsystems, while the first and second mobile device are collocated during a period of time in the future; means for assigning a first task of the set of tasks to be performed by the first mobile device based on the first set of subsystems; and means for assigning a second task of the set of tasks to be performed by the second mobile device based on the second set of subsystems. The first and second sets of subsystems are different from one another with regard to at least one subsystem.
Abstract:
Techniques for determining the position of a mobile device using almanac data are provided as are techniques for providing almanac data to the mobile device from a location server. The almanac data can be provided to the mobile device based on coarse location information provided by the mobile device. The almanac data can include information Media Access Control (MAC) addresses of one or more wireless access points and most recently used channel identification. The almanac data can also be binned by location by the location server and a subset of the almanac data can be selected to be provided to the mobile device based on the coarse location of the mobile device and on positioning effectiveness criteria associated with the wireless access points included in the almanac data.
