摘要： The method includes one or more turnstiles using a non-secure ranging process to detect a proximity of one or more mobile computing devices carried by respective users. The method also includes one of the turnstiles, on making a proximity determination in respect of a first of said mobile computing devices, commencing a secure authentication process to authenticate a user carrying the first mobile computing device. The method further includes, in response to a determination that the user carrying the first mobile computing device has been authenticated, allowing the user carrying the first mobile computing device to pass through the turnstile.

摘要： Embodiments of a method and an apparatus for wireless localization are disclosed. In an embodiment, a method for wireless localization involves obtaining, by an Ultra-Wideband (UWB) radio of a localization device, UWB timing data from UWB anchors, transmitting, via a non-UWB transceiver of the localization device, the UWB timing data to a localization engine, and determining, by the localization engine, a location of the localization device using the UWB timing data.

摘要： Embodiments of methods and a system for wireless transactions are disclosed. In an embodiment, the method includes performing multicast Ultra-Wideband (UWB) ranging, where the multicast UWB ranging includes calculating a distance between a first device and a second device, and calculating an angle of arrival (AoA) of the second device, determining, using the distance and the AoA, whether the second device is located in a transaction zone that is defined by the first device, exchanging wireless transaction information between the first device and the second device when the second device is located in the transaction zone, where the wireless transaction information includes a transaction request, and initiating a transaction upon the second device accepting the transaction request and upon confirming, using the distance and the AoA, that the second device is still located in the transaction zone, and the second device is oriented towards the first device.

摘要： Disclosed are methods and devices for, UWB, ranging of a target using a plurality of antenna arrays. The method comprises: determining a first RSSI, from a first antenna of a first antenna arrays, and a second RSSI from a second antenna of a second antenna arrays; in response to the first RSSI being larger than the second RSSI, selecting the first antenna array, and selecting the second antenna array otherwise; using the selected antenna array, performing a UWB ranging measurement including measuring an angle of arrival of the signal from the target; including, if the angle of arrival of the signal from the target is out of range: selecting a different one of the plurality of antennae arrays, as a presently-selected antenna array; and, using that antenna array, performing a UWB ranging measurement including measuring an angle of arrival of the signal from the target.

摘要： There is disclosed devices and methods of operating a first device to determine a distance, between it and a further device, the methods comprising: transmitting a first broadcast frame comprising an identifier and a transmission timestamp; receiving a further broadcast frame, the further broadcast frame comprising an identifier of the further device, and a transmission timestamp of the further device, and at least one data pair comprising a transmitting device identifier and a reception timestamp, wherein the reception timestamp is indicative of the arrival time, at the further device, of a prior broadcast frame broadcast from the transmitting device; determining a reception timestamp of the further broadcast frame; comparing each transmitting device identifier with the identifier of the first device; and determining the distance between the first device and the further device.
