Abstract: An industrial automation system comprising a digital fingerprint that is allocated to a unit requesting access to the automation system and which is based on one or more parameters of a communication between the unit and a fingerprint-determining component of the automation system, wherein the industrial automation system additional comprises the fingerprint-determining component which, during the operation of the automation system, grants the requesting unit access to the automation system and compares the determined fingerprint of the requesting unit with a stored fingerprint.

Abstract: A radio station system for a wireless network with at least two access network nodes, wherein a first of the at least two access network node is assigned to the radio station system as an access network node in the wireless network and the radio station system is connected to the first access network node over an active radio link for the transmission of user data. During the existence of the active radio link between a first radio station and the first access network node, a second radio station transmits or exchanges no user data via a radio link with an access network node in the wireless network and at least at times identifies available access network nodes in the wireless network for the radio station system.
