A system may be configured to identify from among a plurality of access points in an area in communication with a network, a first access point associated with the area. In addition the system may also be configured to determine first location-related data for the first access point. Determining second location-related data for a second access point of the plurality of access points, the second access point being interior to the first access point within the network includes exchanging ranging data indicative of a first relative distance between the first access point and the second access point, the ranging data based at least in part on ranging message exchange measurements, and communicating the first location-related data from the first access point to the second access point.

Exemplary methods, apparatuses, and systems read location data representing a current location of a mobile device. The location data for the mobile device is taken at a first sampling rate. Upon determining that the location data indicates that the mobile device is approaching a geographic area having a history of wireless communication loss, the mobile device is triggered to increase location data sampling from the first sampling rate to a second sampling rate.

A train position detection apparatus is configured to detect a position of a train by receiving positioning radio waves from satellites through a reception antenna. The train position detection apparatus includes: a memory that stores therein in advance a railway design standard of a railway track on which the train travels; and one or more hardware processors that detect a position of the train by self-contained navigation based on an input signal from a self-contained navigation sensor. When a result of the train position detection based on the positioning radio waves does not satisfy the railway design standard, the one or more hardware processors correct the result of the train position detection based on the positioning radio waves with a result of the position detection by self-contained navigation.

Geolocated information is communicated to a user based upon a position of smart device in a building as determined by optical recognition of a first visual identifier, a second visual identifier and a third visual identifier. A distance determined from each of the visual identifiers, as well as a direction of interest indicated by a user. A user interface is generated for display on a Smart Device based upon the position of the Smart Device and direction of interest.

An information handling system operating a diverse wireless location determination system, comprising receiving an instruction to determine a location of an endpoint information handling system having a plurality of network interface device modules supporting a plurality of wireless network protocols, a processor executing instructions to aggregate data including detected time of flight (TOF) signal distance and signal quality values relating to signals exchanged between the endpoint information handling system and a plurality of diverse wireless protocol access points, the processor to determine at least three diverse wireless protocol access point signals meet a signal quality threshold, where at least two of the diverse wireless protocol access points operate under different wireless protocols, and the processor conducting weighted multiangulation or multilateration utilizing the detected TOF signal distances of the exchanged signals based on the detected signal quality category and type of wireless protocol for the exchanged signal.

A user equipment (UE) receives assistance data for positioning that includes relative position information for anchor points, such as base stations and/or sidelink UEs. The relative position information may include, for example, distances or angles between anchor points. The UE performs positioning measurements for reference signals received from the anchor points. The UE performs outlier rejection of the positioning measurements using the relative position information. Positioning measurements selected by the UE using the relative position information are provided to a location server. The location server may perform UE-assisted positioning using the selected position measurements and the actual locations of the anchor points. Accordingly, the outlier rejection of the position measurements may be off loaded from the location server to the UE while maintaining confidentiality of the actual locations of the anchor points.

Methods and Apparatus relating to environmental monitoring and control systems are discussed. More specifically, the present invention relates to methods and systems for monitoring temperature and other environmental conditions in a cold storage facility and tracking the locations and environmental conditions of a product throughout its cold storage life cycle using the environmental control system and smart devices in logical communication therewith. Tracked interactions with personnel in relationship to products in cold storage are also discussed.

A method for operating a plurality of antennas of a vehicle is disclosed, in which the vehicle communicates wirelessly with an external radio station while traveling through a radio cell of the external radio station by means of a radio signal emitted by the plurality of antennas. The vehicle includes a plurality of antennas and a controller operatively connected to the antennas.

A communication device comprising: a wireless communication section; and a control section configured to correlate a first signal with a second signal from another communication device at a designated interval, convert a data matrix including an array of a plurality of correlation computation results into a format including a matrix product of an expanded modal matrix and an expanded signal matrix, estimate the expanded signal matrix that minimizes a predetermined norm, and estimate reception time of the second signal on a basis of the expanded signal matrix that minimizes the predetermined norm.

The present disclosure provides a positioning method of a target node in a wireless ad hoc network, including: performing an initial positioning to obtain a first positioning result for the target node; determining, based on the first positioning result and a second positioning result for an other node in the wireless ad hoc network, whether a positioning error exists in the first positioning result or not, wherein the second positioning result at least contains an accurate second positioning result; and calculating a third positioning result for the target node based on the accurate second positioning result, in response to determining a positioning error exists in the first positioning result. The present disclosure further provides a positioning apparatus of a target node in a wireless ad hoc network, an electronic device, and a storage medium.
