Samsung patents UWB method to adjust ranging zones using AI
Samsung describes a method where a device uses a trained neural network to analyze Ultra-Wideband (UWB) signals and determine if it has a clear line of sight to fixed anchors. Based on this analysis, the device adjusts the specific area where it can start a secure ranging transaction with a gate device.
In the filing’s own words
The present disclosure discloses a method by which an electronic apparatus adjusts a gate ranging region. The method according to the present disclosure may comprise the steps of, by using a trained first convolutional neural network (CNN) model, acquiring LOS probability data on the basis of a DL-TDoA signal received from at least one UWB anchor, acquiring an average LOS probability on the basis of the LOS probability data, on the basis of the average LOS probability, determining whether or not the electronic apparatus is present in an LOS environment, if the electronic apparatus is present in the LOS environment, maintaining an initially established gate access region, and if the electronic apparatus is present in the LOS environment, adjusting a gate access region according to the value of the average LOS probability. Here, the gate access region may be a region in which the electronic apparatus and a gate apparatus initiate DS-TWR ranging for a transaction.
What exactly they claim (claim 1)
1. A method by an electronic device using UWB communication, the method comprising: obtaining LOS probability data based on a DL-TDoA signal received from at least one UWB anchor using a trained first convolutional neural network (CNN) model; obtaining an average LOS probability based on the LOS probability data; determining whether the electronic device is in a LOS environment based on the average LOS probability; maintaining an initially set gate access area in case that the electronic device is in the LOS environment; and adjusting the gate access area according to a value of the average LOS probability in case that the electronic device is in the LOS environment, wherein the gate access area is an area in which the electronic device and a gate device initiate DS-TWR ranging for a transaction.
