A method of detecting a malicious interference source in a wireless network in an industrial facility includes receiving network quality information from a plurality of network devices, detecting a degradation in a section of the network based on the network quality information from at least one network device, determining a geographical area associated with the section of the network, and determining a location of the malicious interference source based on measurements of at least one network key performance indicator (KPI) from at least one mobile unit in the geographical area.

Method of detecting an interference source in an industrial facility

A radio communication system for an industrial automation system includes at least one first communication device operated as a radio base station, and several second radio communication devices operated as radio subscriber stations, wherein the first communication device is arranged or movable on a vehicle, where the first communication device and the second communication devices can be assigned to a group of communication devices and can only be connected to one another in a wireless manner within the same group of communication devices, where the first communication device and the second communication devices detect within their assigned communication device group distances between the first communication device and the respective second communication device, on the basis of signal strength measurement values or position data and where, depending on the detected distances, the first communication device allocates radio resources for a radio communication with the respective second communication device.

Method and radio communication system for an industrial automation system

A radio communication system for an industrial automation system includes at least one radio base station and at least one radio subscriber station that each have a multiplexer unit for data frames that are to be sent redundantly, where the radio base station and the radio subscriber station each transmit data frames that are to be sent redundantly in parallel using multiple different carrier frequencies and each comprise a redundancy handling unit for processing received redundant data frames, and where the redundancy handling units each detect received redundant data frames or restore redundantly sent data frames from different data frame fragments.

Radio communication system for an industrial automation system and method for operating the radio communication system

The invention relates to a method of connecting a mobile, electronic control and/or monitoring unit ( ) to at least one machine or at least one machine component in a group or a plurality of machines ( ) or machine components to be controlled and/or monitored. During a connection or log-on procedure between the control and/or monitoring unit ( ) and a co-operating distant point on the respective machine ( ), a clear link or log-on connection is set up either by means of interfaces ( ) to the selected, wireless direction-finder of the co-operating distant point or alternatively by means of transmitters and/or receivers ( ) tuned to a restricted, localized functional or operating range ( ). Once the connection has been acknowledged and established, the programmed control and/or monitoring of the machine ( ) or the machine component is managed via another, standard data transmission means ( ), for example a hard-wired network and/or via a wireless link between the control and/or monitoring unit ( ) and the selected machine ( ). Also proposed is a control and/or monitoring unit ( ) for implementing this method.
