摘要： Methods for operating real-time wireless networks enable robust medium access strategies for communicating nodes in the network. A given wireless channel is divided into several sub-carriers, with each node assigned to a subset of sub-carriers. A master wireless node uses different subsets of the sub-carriers to communication with two or more slave wireless nodes simultaneously. The method includes generation of preambles that are robust to interference and multipath conditions. The method also enables communication within a maximum predetermined latency bound.

摘要： A transmission system and a transmission method for the wireless transmission of signals in an automation installation and also an automation installation having such a transmission system is disclosed. The transmission system is used for the wireless transmission of signals between a plurality of elements of an automation installation and comprises a plurality of network nodes, to which a respective element from the plurality of elements of the automation installation is connected. In this context, each network node has an associated separate, continuously useable logical channel which can be used to transmit signals wirelessly.
