A method is provided for localizing mobile tags using a system including a plurality of anchors located at known locations, the method including: transmitting a plurality of ultra-wideband (UWB) localization packets using respective anchors of the plurality of anchors, in which each of the plurality of localization packets is transmitted by a respective anchor of the plurality of anchors at a different respective delay time; and transmitting an update UWB packet with either an anchor of the plurality of anchors that does not transmit one of the localization packets, or with a mobile tag, in which the localization packets include no payloads, the update packet includes a payload, and in which successive ones of the plurality of localization packets and the update packet overlap with each other in time. A system for localizing mobile tags is also provided.

A system and method for determining the presence of an individual at a particular spot within a location preferably based on the strength of signals received from beacons assigned to the particular spot by a software application (“App”) running on an electronic device of the individual. In one embodiment, certain presence calculations are performed by the App. In another embodiment, the App forwards information regarding the received beacon signals to an electronic identification and location tracking system and the presence calculations are performed by the system.

A system and a method for operating a lighting device may include a transmission device and an optional communication unit. The transmission device may be configured to wirelessly transmit a radio signal with identification data specific to the transmission device of the lighting device via at least two radio channels. The transmitted radio signal transmitted via a respective one of the at least two channels may include channel data with respect to the respective one of the radio channels. In a non-limiting embodiment, the transmission device is a beacon.

A system includes a first-vehicle processor configured to receive a signal broadcast from a second vehicle. The processor is also configured to determine a distance between a first transceiver, receiving the signal, and a second transceiver, transmitting the signal. The processor is further configured to determine second vehicle dimensions. Also, the processor is configured to digitally map a second vehicle perimeter around a second transceiver location, determined based on the distance and alert a first vehicle driver of a likely overlap condition of the second vehicle perimeter and a first vehicle perimeter.

Systems and methods for configuring and generating Narrowband Positioning Reference Signals (NPRS) for NB-IoT are provided. A network node provides (NPRS) configuration information indicating a system frame number (SFN) dependent resource mapping. A wireless device obtains a NPRS in accordance with the indicated SFN dependent resource mapping and uses it to perform a radio measurement operation.

An electronic device wirelessly communicates with an information processing device via a wireless communication unit and can operate at least in a first mode and in a second mode that is a state where power consumption is higher than in the first mode. The electronic device includes a direction information acquisition unit and a processor. The direction information acquisition unit acquires direction information about a direction of the information processing device in relation to a reference location of the electronic device by the wireless communication with the information processing device via the wireless communication unit. The processor performs at least one of a transition from the first mode to the second mode and a transition from the second mode to the first mode, based on the direction information.

Methods and systems are provided for determining a location of a device. The methods can include receiving information associated with a device, which can include one or more radio frequency (RF) signal strength values associated with communication between the device and at least one antenna element of an antenna array. The methods can also include, determining, based at least partly on the information associated with the device, a location for the device.

A system including a polarized RF scanning reference source and one or more cavity sensor receivers.

A server device includes: a first receiver to receive, from a settlement terminal, settlement identification information for identifying a settlement method by which the settlement terminal makes a settlement, and portable terminal identification information for identifying portable terminals located within a predetermined distance, the portable terminal identification information being included in a radio wave sent out, and intensity information representing a radio wave intensity of the radio wave received by the settlement terminal; a correlation unit to correlate the portable terminal identification information corresponding to the intensity information of the highest radio wave intensity received by the first receiver, with the settlement identification information; a memory controller to store, in a memory, settlement record information that correlates the settlement identification information with the portable terminal identification information; and an estimation unit to estimate a settlement method used on a per portable terminal basis, based on pieces of the settlement record information stored in the memory.

A method includes: acquiring, from a first communication terminal of a first user via a network, i) a request for an advertisement corresponding to a store and ii) a device identifier (ID) specifying a beacon signal transmitter disposed in the store, the beacon signal being received from the beacon signal transmitter; determining, based on the device ID, one branch store; generating, based on limited product information, the request for the advertisement, and branch store information, privileged advertisement information; and outputting the privileged advertisement information to the first communication terminal.
