The invention relates to a method for deterministic wireless transfer of time-triggered real-time messages in a distributed real-time system, which real-time system comprises a plurality of node computers and one or more base stations, which are arranged in an arena, wherein all node computers and base stations have a global time, wherein one or more real-time message sequences are periodically transferred in the arena, wherein a real-time message sequence consists of a time-triggered header message with variable length and a sequence of one or more time-triggered real-time messages with a priori known length, and wherein, at an a priori determined transmission time, the software of a T-node issues, to a communication controller thereof, the command to send the header message, and wherein the communication controller of the T-node starts to send the header message as soon as no activity is determined in the arena during an IFS, and wherein the sending of the header message is aborted at an a priori determined time-triggered abort time of the T-node, and wherein, in a command interval before the abort time of the header message, the software of the computer node that has to send the first real-time message of the real-time message sequence issues, to the communication controller thereof, the command to send the first real-time message of the real-time message sequence, and wherein, in the command interval before the termination of the first real-time message, the software of the computer node that has to send the following real-time message of the real-time message sequence issues, to the communication controller thereof, the command to send the following real-time message, and wherein this process is repeated until all real-time messages of a real-time message sequence have been sent.
