Abstract: In accordance with a first aspect of the present disclosure, a method is conceived for determining the position of at least one node in a communication network, wherein the communication network comprises a localization system that includes a processing unit, a primary anchor and at least one secondary anchor, the method comprising: the primary anchor transmits a poll message to the node and to the secondary anchor; the primary anchor receives a response message from the node; the secondary anchor receives said poll message from the primary anchor and said response message from the node; the processing unit calculates the position of the node using position information and timing information, wherein said position information is position information of the primary anchor and of the secondary anchor, and wherein said timing information is timing information of the poll message transmission by the primary anchor, of the poll message reception by the node and the secondary anchor, of the response message transmission by the node, and of the response message reception by the primary anchor and the secondary anchor.

Abstract: There is described a method of determining a time of arrival of a signal at a UWB ranging device comprising a first antenna, the signal being transmitted by another UWB ranging device, the method comprising: determining a first channel impulse response based on at least a part of the signal received at the first antenna; determining a first time value as an earliest point in time at which the amplitude of the first channel impulse response exhibits a peak value; setting a candidate time value to the first time value; determining a first upper value as the amplitude of the first channel impulse response at a time value corresponding to the candidate time value plus a predetermined upper time value; determining a second upper value as the peak value plus a predetermined upper amplitude value; determining a first lower value as the amplitude of the first channel impulse response at a time value corresponding to the candidate time value minus a predetermined lower time value; determining a second lower value as the peak value minus a predetermined lower amplitude value; determining, as a first condition, whether the first upper value is larger than the second upper value; determining, as a second condition, whether the first lower value is smaller than the second lower value; and if at least one of the first condition and the second condition is not fulfilled, setting the time of arrival to the candidate time value. Furthermore, a UWB ranging device and a UWB system are described.

Abstract: It is described a method of UWB-based communication between a mobile device (101, 401) and at least one peer device (102, 402a,b,c), the method comprising while the mobile device (101, 401) is in an idle mode: a synchronizing step (410) including that the mobile device (401) sends at least one synchronization message (418) without performing full Ranging cylce; the peer device (402) receiving the synchronization message (418); and the peer device (402) synchronizing with the mobile device (410) based on the received synchronization message (418); the method comprising while the mobile device (401) is in a non-idle mode: the mobile device starting a UWB-based DS-TWR session (425, 525, 526) with the synchronized peer device, in order to control the smart-device (402c, 502c) via the mobile device.
