Abstract:
Techniques are provided, which may be implemented via various methods, apparatuses, and/or articles of manufacture. For example, an electronic device may obtain an estimated location of a mobile device, determine a quality of a geometric distribution of transmitting devices capable of transmitting wireless signals to the mobile device at the estimated location, and assign an uncertainty to the estimated location. In certain implementations, an electronic device may further determine an adapted transmission setting for a transmitting device and transmit a corresponding message to the transmitting device. In certain implementations, an electronic device may identify adapted assistance data for the mobile device and transmit a corresponding message to one or more other electronic devices.
Abstract:
Systems, apparatus and methods for determining whether to use an indoor map or an outdoor map based on local area network (LAN) signals from access points (APs) are disclosed. If only weak AP signals belonging to a location content identifier (LCI) are received, prior art systems display an indoor map associated with the LCI. An improvement herein further determines a quality of AP signals and/or wide area network (WAN) signals before determining whether to display the indoor map or an outdoor map.
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:
Techniques are provided which may be implemented using various methods and/or apparatuses in a vehicle to determine proximate vehicles, for example, vehicles within a pre-designated range or within broadcast distance or otherwise geographically proximate, through the use of broadcast or other messages sent by the other vehicles, and to obtain GNSS carrier phase measurement data from the proximate vehicles wherein the shared carrier GNSS phase measurement data may be utilized to update the location(s) of proximate vehicles.
Abstract:
A wireless communication device includes: a memory; a transceiver; and a processor communicatively coupled to the memory and to the transceiver and configured to: obtain a first device identity for each of a plurality of first radio-frequency (RF) devices each configured to transmit a wireless RF signal; obtain a mobility status for each of the plurality of first RF devices, the mobility status indicative of whether the respective first RF device is expected to be mobile or static; obtain an RF signal measurement for each of the plurality of first RF devices; and produce a profile of the plurality of first RF devices using the first device identity for each of the plurality of first RF devices, the mobility status for each of the plurality of first RF devices, and the RF signal measurement for each of the plurality of first RF devices.
Abstract:
A method of using one or more radio-frequency signals includes: monitoring, with at least one radio-frequency (RF) receiver, one or more RF characteristics of one or more wireless RF signals from one or more RF devices in an environment; comparing the one or more RF characteristics to a reference RF profile for the environment; and initiating an action based on a difference between the one or more RF characteristics and the reference RF profile determined by the comparing.
Abstract:
A method of associating environmental context with wireless access points is disclosed. In some embodiments, a method on a user equipment may comprise determining at least one environmental context associated with a subset of one or more Access Points (APs) visible to the UE at an estimated location of the UE. The at least one environmental context associated with the subset may be determined based on one or more of wireless measurements by the UE, and/or sensor measurements by the UE. Further, at least one AP cluster may be determined by clustering the subset of the one or more APs visible to the UE based on the at least one environmental context and the estimated location. Environmental context for APs may be crowdsourced and stored and provided to a UE as location assistance information to facilitate location determination and other functions.
Abstract:
Disclosed embodiments facilitate combining a plurality of wireless signal measurement sets with displacement measurements within some time interval of a position request to determine a User Equipment (UE) position. A first set of wireless signal measurements may be obtained from a first set of base stations at a first time at a first location. Subsequently, a second set of wireless signal measurements from a second set of base stations may be obtained at a second time at a second location distinct from the first location. A displacement measurement (e.g. a displacement vector) between the first location and the second location may be obtained. The position of the UE at the second location may then be determined based on the first and second sets of wireless signal measurements and the displacement measurement. In some embodiments, the first and second sets of wireless signal measurements may each be deficient measurement sets.
Abstract:
Disclosed is an apparatus and method for synchronization of sensing operations performed by a plurality of devices. The method may include collecting sensing capabilities of one or more connected devices that are communicably coupled with a central device. Each connected device may include one or more sensors, and the sensing capabilities may include at least sensor type and sensing interval for each sensor. The method may also include coordinating sensing operations performed by the central device and the one or more connected devices.
Abstract:
Method and apparatus for processing access point (AP) crowdsourcing data are disclosed. In one embodiment, the method comprises receiving WiFi scan lists and their corresponding location descriptions, where the WiFi scan lists and their corresponding location descriptions include information observed about at least one access point device, consolidating the WiFi scan lists and their corresponding location descriptions based at least in part on a set of selection criteria to generate a WiFi AP record, where the set of selection criteria comprises a maximum number of scan lists to be uploaded in a predetermined period of time and the maximum number of scan lists to be uploaded in a single upload, and uploading the WiFi AP record to a crowdsourcing server.
