A star topology network comprises a user device, a central gateway, and one or more sensor nodes added to the existing network. A communication between the user device and the central gateway is secured either based on public-key cryptography, symmetric-key cryptography, or by the use of a secure channel such as a wired communication. A request from the user device to the central gateway can be transmitted over the internet.

For coupling a first communication partner with a second communication partner, a signal source sends a radio signal to the first communication partner via a first channel. The first communication partner ascertains a first measured value of a measuring variable related to the first channel during the receiving of the radio signal, ascertains a first comparative value as a function of the first measured value, and sends the first comparative value to the second communication partner. The second communication partner ascertains a first relationship measure between the first comparative value and a second comparative value, and couples with the first communication partner if the first relationship measure exceeds a specified threshold value.
