A vehicle movement tracking system that employs floor mats having ridges for generating location information in the form of modulated vibrations, detectable with an accelerometer. Two sensors are in a wheel of a vehicle. One sensor senses wheel rotation, and the other sensor senses vertical acceleration. The vehicle passes over a floor mat comprising vertically elevated ridges thereon that code the mat and thereby indicate the location at which the mat is at. When the vehicle travels over this mat the vertical acceleration sensor in the wheel detects the vertically elevated ridges and the wheel rotation sensor detects the distance between the vertically elevated ridges. In combination these two sensors are used to create a location word that denotes the mat over which the vehicle passes over. The location word is stored in non-volatile memory and later uploaded to a location collection station.

The described technology is generally directed towards user equipment geolocation. Network measurement data associated with user equipment can be separated into static periods in which the user equipment was not moving, and moving periods in which the user equipment was moving. Static location processing can be applied to determine static locations from the static period network measurements, and moving location processing can be applied to determine moving locations from the moving period network measurements. Resulting static location information and moving location information can then be merged in order to improve the accuracy of both the static and the moving location information. The enhanced accuracy location information can be stored and used for any desired application.

A method and apparatus for determining pose of a transmitter, and by extension the pose of one or more receivers, in an electromagnetic tracking system when the transmitter is allowed to move freely in the physical environment. The method operates in a system that incorporates two separate tracking technologies and an Inertial Measurement Unit, one determining the pose of a device relative to a global reference frame and another determining the pose of the same device relative to a local reference frame, thereby avoiding the latency problem and resulting inaccuracy of pose determinations of known prior approaches.

An Internet of Things (IoT) device, receives, from an Access Point (AP), a beacon signal including unique identifier information of the AP, which is generated based on position coordinates of each position while at least one mobile robot equipped with the AP moves; records an RSSI value, unique identifier information of the AP, and the position coordinates from each of the received beacon signals in a reception list table; selects the best three or more RSSI values in the reception list table; calculates distances to three or more APs respectively corresponding to the three or more RSSI values by using the three or more RSSI values; and estimates the position of the IoT device by using the distances to the three or more APs.

A computing system receives location data from a computing device of a transport provider and based on the location data, monitors a location of the transport provider as the transport provider operates a vehicle to travel towards a service location of the service request. The system determines, based on monitoring the location of the transport provider, that the transport provider has not indicated at least one of a correct start location or a correct start time for fulfilling the service request. In response to determining that the transport provider has not indicated the at least one of the correct start location or the correct start time, the system uses a set of the location data received from the computing device of the transport provider to determine the at least one of the correct start location or the correct start time for fulfilling the service request.

A system to assist in monitoring and improving services in hotels, motels and other lodging facilities. The system includes a plurality of fixed-location wireless devices that are situated throughout the facility and each service provider or asset to be monitored or tracked is provided with a cooperating mobile wireless device. The mobile devices may periodically transmit beacons that are received by the fixed location devices. The system may determine location based on evaluation of signal strength across a plurality of fixed devices. The system may include premapped calibration data on signal strength to assist in determining location. The location information may help to assess employee performance, to assist in improving performance and to provide improved services. The system may also interact with an application running on a hotel guest's electronic device to allow the system to track guest location. Guest location information can be used to provide improved guest services.

A system and method for frequency offset determination in a MANET via Doppler nulling techniques is disclosed. In embodiments, a receiving (Rx) node of the network monitors a transmitting (Tx) node of the network, which scans through a range or set of Doppler nulling angles adjusting its transmitting frequency to resolve Doppler frequency offset at each angle, the Doppler frequency shift resulting from the motion of the Tx node relative to the Rx node. The Rx node detects the net frequency shift at each nulling direction and can thereby determine frequency shift points (FSP) indicative of the relative velocity vector between the Tx and Rx nodes. If the set of Doppler nulling angles is known to it, the Rx node can determine frequency shift profiles based on the FSPs, and derive therefrom the relative velocity and angular direction of motion between the Tx and Rx nodes.

A computer implemented method in a communications network for determining location information about an actual location of a drone comprises obtaining (302) a reported location of the drone at a first time point and obtaining (304) a measurement of radio conditions between the drone and a node in the telecommunications network, at the first time point. The method then comprises predicting (306) radio conditions at one or more locations related to the reported location of the drone, and determining (308) the location information about the actual location of the drone based on the measured radio conditions and the predicted radio conditions.

An operating method of a first device (100) in a wireless communication system is presented. The method may comprise the steps of: receiving, from a second device (200), through a first band, a positioning request including at least one candidate band and information related to positioning; determining, from the at least one candidate band, a second band on the basis of the number of devices present in each candidate band and a value related to the communication range based on the first device (100); transmitting, to the second device (200), through the first band, a positioning response including information related to the determined second band; and transmitting, to the second device (200), through the second band, a first positioning reference signal (PRS) on the basis of the information related to positioning.
