Abstract:
A method for transferring data packets in a network of multiple user stations, the data packets being transferred over a set of channels with the frequency-hopping method and the channels being in this context selected for data transfer in accordance with at least one frequency-hopping pattern in temporal succession, in which the network is divided into at least two basic networks, each with a central station and a limited number of user stations; and in each basic network a separate frequency-hopping pattern is processed that is orthogonal to the frequency-hopping pattern of immediately adjacent basic networks, wherein data packets are exchanged for synchronization purposes between the first central station and the second central station via one of the user stations connected to the first central station, wherein the first central station is connected to the one of the user stations via a wireless connection and the second central station is connected to the one of the user stations via a wired connection.
