Accurate position capability can be quickly provided using a Wireless Local Area Network (WLAN). When associated with a WLAN, a wireless device can quickly determine its relative and/or coordinate position based on information provided by an access point in the WLAN. Before a wireless device disassociates with the access point, the WLAN can periodically provide time, location, and decoded GPS data to the wireless device. In this manner, the wireless device can significantly reduce the time to acquire the necessary GPS satellite data (i.e. on the order if seconds instead of minutes) to determine its coordinate position.

Systems, methods, and devices are disclosed for enabling a mobile device with limited RF capability to obtain accurate directions for finding an object or asset via a multiple-antenna locator device. The mobile device generates a request to the locator device to obtain directions to find the asset. A request can also be made to obtain the mobile device's own location from the multiple-antenna locator device which has an antenna array and is in a fixed location that has good RF visibility. The locator device identifies the target asset and receives an RF signal from it using the antenna array. The signal is detected at each antenna and phase samples are recorded. The phase sample data is used in angle-related functions, such as angle of arrival and angle of departure algorithms to calculate the direction of the asset.

Some embodiments relate to a method for locating a mobile target for a tracking vehicle, including a first communication module in a first location on the tracking vehicle in order to determine a first distance measurement between the first location and the mobile target at a first time, and a second communication module at a second location on the tracking vehicle in order to determine a second distance measurement between the second location and the mobile target at a second time, and a processing module for determining a forecast of the movement of the tracking vehicle between the first and second times, and for determining a location of the mobile target relative to the tracking vehicle from the first and second distance measurements, taking into account the forecast, so as to compensate for the movement, between the first and second times.

A system for measuring the position of one or more object in an area of interest. The system has one or more portable tag which is attachable to the object and four or more beacons each positioned in separate fixed locations in or near the area of interest, The beacons have a primary beacon function and a secondary beacon function and the portable tag measures the time referenced signal from the beacon using its primary beacon function and the time referenced echo from the beacons using their secondary beacon function to calculate the position of the portable tag with respect to the beacon. A controller switches said beacons between their primary beacon function and their secondary beacon function to create a plurality of calculations of the position of the portable tag.

The application relates to a method for positioning a user equipment (UE) in a cell served by a base station (BS), the BS comprises an array antennas capable of forming two or more beams in the cell, the method comprising: receiving beam information indicating which beam is selected, from the two or more beams, for serving the UE; and positioning the UE by determining an area where the UE is located in the cell based on the beam information. A network device, such as a radio network controller, and a base station for implementing the method are also disclosed. The method can be used with an RTT positioning method to improve the accuracy of position.

Position determination for a mobile station is achieved through the modification of certain Wi-Fi access point and station signals, that are radiated by a certain master (i.e., guiding) base station, combined with slave (i.e., guided) stations having known coordinates, and processing the signals received from these base stations at the mobile station to determine the desired position.

Certain cellular communication systems may use beamforming to create distinct signal beams in different radial directions relative to a base station. Upon receiving a request for the location of a mobile device, a position calculation function is used to calculate the location of the mobile device based on multiple types of location-related data. The location-related data may indicate the direction of the directional signal beam that is currently being used for communications between the mobile device and a base station. The direction may be used in conjunction with other location-related data, such as distance information, to estimate the location of the mobile device.

A method for determining a location of a vehicle. The method includes obtaining, by a marker reader of the vehicle, a marker location from a signal emitted by a marker located in a vicinity of the vehicle. The marker location is provided relative to a known reference point. The method further includes obtaining vehicle location information relative to the first marker using at least one sensor disposed in the vehicle, and obtaining an estimate of the vehicle location relative to the known reference point, using the marker location and the vehicle location information.

The present disclosure generally relates to localization and, more particularly, to remote localization and radio-frequency identification using a combination of structural and antenna mode scattering responses. A method and system include receiving location data of an object from a plurality of transmitter-reader pairs (TRPs); generating a plurality of first ellipses representing the received location data; determining blocking likelihoods at points of intersection between the plurality of first ellipses; generating additional ellipses representing additional location data received from additional TRPs; and updating the blocking likelihoods at points of intersection between the plurality of first ellipses and the additional ellipses.
