Abstract
In order to detect movements of objects and/or living beings in a radio range, which enables easily with a minimum of hardware complexity an automated movement detection based on a Single-Sensor, it is proposed to: Collect as input data for the movement detection based on received 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 a set of “Channel State Information”-values, determine a change in the received radio signals, which are derived from the facts that the movement influences the transmitted radio signal in the radio range based on the collected CSI-values by the indication of a statistical parameter value, and assess on the basis of the statistical parameter value a “chaos index” value until the “chaos index” value in accordance with a threshold check provides a reliable statement.
