Abstract:
1. A network comprising: several network clusters each network cluster having at least one wireless network node and at least two fixed network nodes, each of the at least two fixed network nodes belonging to a sub-network and exchanging data with other fixed network nodes of the sub-network through wire connections, each of the at least two fixed network nodes and the other fixed network nodes being coupled to a respective wireless network node of the at least one wireless network node via a respective wire interface, each of the at least one wireless network node including a transmitter for the wireless transmission of packets in time slots of given length in a time multiplex process, the variable length of the packets having at least a value which is smaller than the length of a fixedly given time slot, wherein a transmitting wireless network node of the wireless network nodes is configured for combining several packets into a superpacket and for transmitting the superpacket to all wireless network nodes authorized for the data transmission via a point-to-multipoint link, wherein the superpacket is transmitted to all wireless network nodes in one or more time slots of the fixedly given time slots wherein each of the one or more time slots includes at least two packets of the superpacket, and wherein a receiving wireless network node of the wireless network nodes after reception of the superpacket is designed to extract a packet from the superpacket if the destination of the packet of the superpacket lies in a network cluster corresponding to the receiving wireless network node; the transmitting wireless network node being configured for segmenting the superpacket into cells when the length of the superpacket exceeds the length of the fixedly given time slots, and for inserting the cells into several time slots, wherein each cell includes at least two packets from the superpacket, and the receiving wireless network node which receives the cells being configured for forming the superpacket from the cells.
