Method and locating device for locating radio tags, and method and arrangement for configuring the locating device

A method for configuring a locating device for locating radio tags, the method comprising:

• a) conveying one or more first radio tags many times under varied conveying conditions through a predefined area, wherein in each case
• a current position of a respective first radio tag is captured by a localization sensor, and
• a radio signal from the respective first radio tag is received and a respective signal strength curve of the received radio signal is captured;
• b) training a machine learning module on a basis of the captured current positions and signal strength curves, to reproduce a corresponding current position on a basis of at least one signal strength curve;
• and
• c) configuring the locating device to feed signal strength curves of received radio signals from second radio tags into the trained machine learning module and to determine a respective current position of a respective second radio tag on a basis of the resulting output signals from the machine learning module, wherein a reproduction error of the machine learning module is captured,
• wherein specific signal components which at least on average reduce the reproduction error when fed into the machine learning module are searched for in captured signal strength curves, and
• wherein signal components found in this manner are deliberately extracted from captured signal strength curves and are fed into the machine learning module in order to train and/or use the machine learning module.
