Device positioning
An apparatus, method and computer program is described. The method can include receiving a first measurement report from a first communication node of a mobile communication system. The first measurement report can include downlink measurement data generated at a user device in response to a positioning reference signal sent by the first communication node. The method can further include receiving a second measurement report from the first communication node. The second measurement report can include uplink measurement data generated at the first communication node in response to an uplink reference signal sent by the user device. The method can also include determining an integrity of the measurement data based on a comparison of said uplink and downlink measurement data and setting an integrity verification notification in accordance with the determined integrity.
GEOLOCATIONING SYSTEM AND METHOD FOR USE OF SAME
A geolocationing system and method for providing awareness in a multi-space environment, such as a hospitality environment or educational environment, are presented. In one embodiment of the geolocationing system, a vertical and horizontal array of gateway devices is provided. Each gateway device includes a gateway device identification providing an accurately-known fixed location within the multi-space environment. Each gateway device includes a wireless transceiver that receives a beacon signal from a proximate wireless-enabled personal locator device. The gateway devices, in turn, send gateway signals to a server, which determines estimated location of the wireless-enabled personal locator device.
UNMANNED VEHICLE RECOGNITION AND THREAT MANAGEMENT
Systems and methods for automated unmanned aerial vehicle recognition. A multiplicity of receivers captures RF data and transmits the RF data to at least one node device. The at least one node device comprises a signal processing engine, a detection engine, a classification engine, and a direction finding engine. The at least one node device is configured with an artificial intelligence algorithm. The detection engine and classification engine are trained to detect and classify signals from unmanned vehicles and their controllers based on processed data from the signal processing engine. The direction finding engine is operable to provide lines of bearing for detected unmanned vehicles.
Hybrid positioning techniques based on RTT and TOA/TDOA
Example methods, apparatuses, or articles of manufacture are disclosed herein that may be utilized, in whole or in part, to facilitate or support one or more operations or techniques for hybrid RTT and TOA positioning, such as for use in or with a mobile communication device, for example.
Positioning with wireless local area networks and WLAN-aided global positioning systems
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 of seconds instead of minutes) to determine its coordinate position.
SYSTEMS AND METHODS FOR USING DOPPLER MEASUREMENTS TO ESTIMATE A POSITION OF A RECEIVER
Estimating the position of a receiver using positioning signals and Doppler frequency measurements. Approaches for estimating the position of a receiver using positioning signals and Doppler frequency shift measurements determine an initial estimate of a receiver's position using ranging signals from a first system, generate Doppler frequency shift measurements using the Doppler positioning signals from a second system, and refine the initial estimate using the Doppler frequency shift measurements.
RFID tag search method, non-transitory storage medium storing RFID tag search program, and RFID tag search device
A method to be executed by a user terminal for searching for locations of one or more wireless devices that are located within an area in which the one or more wireless devices can wirelessly communicate with the user terminal, wherein each of the one or more wireless devices periodically transmits a beacon signal. The method includes detecting a number of the one or more wireless devices that are located within the area based on the beacon signals; determining a transmission period for transmitting the beacon signals depending on the number of the one or more wireless devices; and instructing the one or more wireless devices that are located within the area to transmit the beacon signals in accordance with the determined transmission period.
RFID tag search method, non-transitory storage medium storing RFID tag search program, and RFID tag search device

The method includes detecting a number of the one or more wireless devices that are located within the area based on the beacon signals; determining a transmission period for transmitting the beacon signals depending on the number of the one or more wireless devices; and instructing the one or more wireless devices that are located within the area to transmit the beacon signals in accordance with the determined transmission period.
METHODS FOR PERFORMING PARALLEL WIRELESS SIGNAL MEASUREMENTS
Systems, methods, and apparatuses are presented for performing parallel uplink wireless signal measurements (UL measurements), in which a signal measuring apparatus determines information on UL measurements being performed or to be performed by the signal measuring apparatus over a predetermined measurement period. The signal measuring apparatus further determines a capability of the signal measuring apparatus to perform parallel UL measurements. The signal measuring apparatus may adjust a measurement requirement or a measurement resource based on a comparison of the UL measurements being performed or to be performed over the measurement period with a capability of the measuring apparatus to perform parallel measurements. The signal measuring apparatus performs the UL measurements based on the adjusted measurement requirement or adjusted measurement resource.
Rotation based alignment of a group of wireless tags
A method for determining a location of a wireless tag, the method may include generating or receiving, by a tagged mobile device, an estimated location of another tag that communicates with the tagged mobile device; receiving or generating, by the tagged mobile device, multiple distance measurements that are obtained during different points of time; wherein the multiple distance measurements are obtained during a rotational movement of the tagged mobile device and represent distances between the tagged mobile device and the other tag; finding a certain angle of rotation of the mobile device that corresponds to a minimal distance measurement of the multiple distance measurements; and amending the estimated location of the other tag based upon the certain angle of rotation.
