The invention relates to a method for determining an angle of arrival of a received radioelectric signal implemented by a receiving antenna system including either one rotating antenna having at least two receiving channels, or two rotating antennas with a same speed each having a receiving channel, and having different antenna diagrams. The method includes, in the operational phase, the following calculating and storing a series of ambiguous angle error measurement values obtained from receiving amplitude values of a radioelectric signal coming from an emitting source on said first and second receiving channels, each angle error measurement value being representative of a ratio between receiving amplitude values on said first and second receiving channels, and corresponding to an angular deviation relative to a reference angular value; calculating a convolution function on said angular range tween said series of ambiguous angle error measurement values and a series of theoretical angle error measurement values of said receiving channels previously calculated and stored, determining an angle of arrival of said received radioelectric signal as a function of an estimate of a maximum of said calculated convolution function.

An object of the present invention is to provide a terminal authentication device that can suppress a troublesome operation to authenticate a terminal when the terminal is connected to a network. A reception unit receives a beacon signal broadcasted from a terminal. A position determination unit determines the position of the terminal using the received beacon signal. A connection control unit controls the terminal to be connected to a mesh network in the case where the determined position of the terminal is within a predetermined authentication possible region.

A wireless animal location system is provided that identifies a location of a pet roaming within an environment using a single base unit. The wireless animal location system tracks and manages animal behavior in the environment using information of pet location.

User equipment (UE), an enhanced NodeB (eNB) and method of improving positioning accuracy and enabling vertical domain positioning of the UE are generally described. The UE may receive a prsInfo control signal having at least one PRS configuration and subsequently a plurality of Reference Signals (RSs). The RSs may have a first Positioning Reference Signal (PRS) pattern in a first set of PRS subframes and a second PRS pattern in a second set of PRS subframes received prior to a subsequent first set of PRS subframes. The RSs may have a vertical positioning RS and a lateral positioning RS. The UE may measure PRS resource elements (REs), each having a PRS, in the first and second PRS pattern. The UE may transmit a measurement of the PRS in the first and second PRS pattern. The patterns may enable horizontal and vertical positioning to be determined.

A tracking system that tracks persons and/or objects of interest without the need for triangulation techniques is disclosed. The tracking system utilizes very low power active radio frequency tags with limited effective broadcast range that operate only in the transmit mode with no need to establish two-way communication with any part of the system. The person or object of interest is provided with a radio frequency tag incorporating a unique identifier. Gateways connected to a common network interface are positioned relative to specific areas within the facility to be monitored. A computer connected to the same network as the gateways analyzes data relating to the strength of the of the radio frequency signals received by the radio frequency receivers from the radio frequency tags to determine if, and when, persons and/or objects of interest are present within particular subareas within the facility.
