Abstract: A method for regulating transmission of a plurality of industrial devices in a first section of an industrial facility is disclosed. The method includes measuring radio signal strength at a first location in the first section and comparing the measured radio signal strength against a predefined threshold associated with the first location in the first section. The radio signal strength is associated with one or more signals transmitted by at least one industrial device of a first wireless network in the first section. The comparison of the measured radio strength against the predefined threshold is performed for transmitting a message to the industrial device. Based on the message, the at least one industrial device is configured to adjust at least one transmission parameter of the industrial device.

Abstract: A method for operating a radio communication system for an industrial automation system, which includes at least one base station and a plurality of subscriber stations, wherein at predefined transmission times the base station cyclically polls datagrams to be transmitted by the subscriber stations, where the base station predefines for the subscriber stations the transmission times, within a polling cycle, for transmitting the datagrams to be transmitted, where the transmission times are each determined from a preceding transmission time by adding a polling cycle duration and subtracting a delay time, while the at least one datagram to be transmitted prior to the preceding transmission time is already in the corresponding subscriber station and ready for transmission, and where the subscriber stations transmit information to the base station regarding the corresponding delay time to determine the transmission times.

Abstract: For wireless communication in the industrial environment, there is, inter alia, an iWLAN protocol, which meets the requirements but provides no time synchronization in the data transmission. According to the invention, an additional—ideally wireless—channel is used for the synchronization. In an advantageous embodiment of the invention, a simple radio system is used for this. Pulses or telegrams for time synchronization are initiated directly from a unit, which is designed as hardware and which is responsible for the time synchronization and which has a highly accurate clock, or supplied on the side to be synchronized of such a unit. The radio system can be designed very simply and unidirectionally. The transmission process is started without delay in order to prevent variable delays.

However, when a mobile device (2) is connected, the lines are separated and connected to a control logic (5) on the mobile device side. By this means the identity (ID) of the connectivity box (1) is transmitted to the mobile device (2).
