| 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. | ||

| 主权项 | 1. A method for wireless transmission of data packets between network nodes of a control network, the data packets each having a preamble for synchronization consisting of a predetermined number of preamble symbols, the method comprising the steps of: coding each preamble subsymbol of a preamble symbol in the preamble by a phase angle of a transmitted single signal pulse during a first operating mode; and transmitting a signal pulse sequence for coding the preamble subsymbol instead of a single signal pulse during a second operating mode such that the single signal pulse is transmitted repeatedly within the single pulse sequence to increase a signal recognition performance for the preamble which is transmitted in a data packet. | ||
