摘要: Method for wire-free transmission of data packets between network nodes in a control network, wherein the data packets each have a preamble for synchronization consisting of a predetermined number of preamble symbols, and wherein during a first operating mode, each preamble-subsymbol of a preamble symbol in the preamble is coded by the phase angle of a transmitted single signal pulse, during a second operating mode to increase the signal recognition performance, for the preamble which is transmitted in the data packet, a signal pulse sequence for coding the preamble-subsymbol is transmitted instead of a single signal pulse, where the single signal pulse within the signal pulse sequence is transmitted repeatedly.
