A method, device, and system for detecting/recognizing in a radio range repetitive motions with at least one motional speed and each at least one repetition, is provided. The method includes the steps of collecting as input data for the repetitive motion detection/recognition based on the reception of quantifiable radio signals of an intended or unintended communication between a transmitting radio terminal being mobile or fixed and a receiving local fixed radio device in the radio range “Received Signal Strength”-values related quantities or “Channel State Information”-quantities, and determining a pattern in the received radio signals, and accessing the peak value until the peak value in accordance with a threshold check provides a reliable statement, particularly being used for controlling purposes.
