A safety system and a method for localizing at least one object having a control and evaluation unit have at least one radio location system. The radio location system has at least three arranged radio stations. Position data of the object can be determined by means of the radio location system and can be transmitted to the control and evaluation unit. At least three radio transponders are arranged at the object, each arranged spaced apart from one another and the three radio transponders form different points on a plane and unambiguously define the plane in space. The control and evaluation unit is configured to compare the position data of the radio transponders and to form checked position data of the object. The control and evaluation unit is configured to form orientation data of the object from the position data of the radio transponders.

Prior arrangement information is automatically fetched in response to detection that a radio presence advertising mobile device of a user is disposed in a region of interest that is operatively adjacent to a transaction-processing location. The fetched information is used to automatically modify the transaction.

Disclosed is a method and apparatus for estimating a signal source, the method including receiving, in at least one receiving node, a signal emitted from a signal source, extracting a steering matrix corresponding to a virtual antenna array by vectorizing the signal received in the at least one receiving node, and estimating a location of the signal source based on the steering matrix.

Methods and apparatus for transmitting information associated with verified positions of Nodes based upon wireless communications between Nodes included in an array. Values for variables derived from multiple wireless transmissions between Nodes are aggregated, and a position of a particular Node may be determined based upon multiple data sets generated by multiple communications between disparate Nodes. Information is geolocated based upon the respective positions of the disparate Nodes. A user interface may provide a pictorial view of positions of all or some Nodes in an array, as well as associated information.

An indoor positioning method detects a moving object defines a possible location area of the moving objects according to errors calculated by RSSI values of the moving object, and calculates RSSI moving vectors between the moving object and wireless devices according to the RSSI values to predict an exact position of the moving object according to the dependency of the RSSI moving vectors and relative angular positions of the moving object. The high relevance feature between CCI of multi-nodes and CINR is transformed as vectors and the vectors are compared with the RSSI moving vectors to calculate a RMSE value. When the root mean square error is less than a preset threshold value, the exact position of the moving object can be obtained.

Embodiments herein describe performing AoA resolving to identify a plurality of AoAs corresponding to a multipath signal and then using AP voting to identify a location of the client device. AoA resolving enables an AP to identify the different angles at which a multipath signal reaches the AP. That is, due to reflections, a wireless signal transmitted by a single client device may reach the AP using multiple paths that each has their own AoA. The AP can perform AoA resolving to identify the AoAs for the different paths in a multipath signal. In one embodiment, the AoAs for two APs (or a subset of the APs) can be used to identify cross points or intersection points that represent candidate locations of the client device. A voting module can determine whether those cross points corresponds to AoAs identified by the remaining APs.

A location system for determining a position of a device is described here. The location system comprises a memory and a processor, the processor executes the computer-executable instruction to perform operations. The operations include sending a first instruction to a locator beacon to determine a first location of the device based on angle of arrival calculation of a first set of one or more packets received from the device. The operations further include sending a second instruction to the device to determine a second location of the device based on angle of departure calculation of a second set of one or more packets received from the locator beacon. Furthermore, the operation includes receiving the first location from the locator beacon and receiving the second location from the device. The operations further include determining the position of the device based on a function of the first location and the second location.
