The invention relates to a method for establishing an end-to-end communication between two networks, wherein: a message is received from one first network, this message having a first header and an application-data part; data of said first header is coded into a second header within the application data part, with the aid of a first coding scheme, so as to produce a modified application data part; said modified application data part is coded with the aid of a second coding scheme so as to produce a coded message; and this coded message is transmitted to a second network.

Method and device for establishing an end-to-end communication between two networks

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, which preamble consists of a predetermined number of preamble symbols; wherein, in a first operating mode (FIG.), each preamble-subsymbol (Cj, Cj+1) of a preamble symbol in the preamble is coded by the phase angle of a transmitted single signal pulse; wherein, in a second operating mode (FIG.), in order to increase the signal recognition performance, for the preamble which is transmitted in the data packet, a signal pulse sequence (SIF) for coding the preamble-subsymbol (Cj, Cj+1) is transmitted instead of a single signal pulse, in which signal pulse sequence (SIF) the single signal pulse is transmitted repeatedly.

Method and apparatus for wireless transmission of data packets

A method establishes an IP-based communications connection between an electric vehicle and a charge control unit associated with a charging station assigned an IP address. The electric vehicle is connected to the charging station via a charging cable and/or an inductive charge coupling for charging and/or discharging. A first communication connection that can be used exclusively by the electric vehicle and the charging station is provided via the charging cable and/or the inductive charging coupling. The electric vehicle having the charging control unit and the charging infrastructure can communicate via a second communications connection that can be used in parallel by other electric vehicles and charge control units. An identification is provided to the electric vehicle and the charging control unit. An IP-based communication is established between the electric vehicle and the charging control unit, using the IP address.

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.

A method of associating time slots with a transmission path in a wireless interconnected network made of a plurality of network nodes such that the transmission path extends between a source node and a destination node and comprises a plurality of sequential links between adjacent network nodes, data being transmitted in the network on a time slot basis by the association of the time slots to be used with the links of the transmission path, wherein a quality value is determinable for each link within an association sequence of time slots describing an end-to-end data transmission from the source node to the destination node along the transmission path, where the value represents the reliability of the data transfer. An overall quality value for the association sequence can further be determined as a function of the quality values of each of the links.

An ultra-broadband signal having a plurality of pulses is transmitted from one or more transmitting nodes to one or more receiving nodes. In the ultra-broadband signal, data are transmitted by pulses having a first pulse rate in a first data transmission and by pulses having a second pulse rate in at least one second data transmission, with each second pulse rate higher than the first pulse rate. The pulses having the second pulse rate are transmitted in intervals, during which no pulses having the first pulse rate are transmitted. This has the advantage that by utilizing time gaps between pulses of the first data transmission, the data of a second data transmission can be transmitted at a higher pulse rate. The transmitting and receiving nodes need not be coordinated explicitly or coordinated from the outside.

Method for pulse-based ultra-broadband communication between at least one transmitting node and at least one receiving node

A bus device that has recently been connected to a bus system is first addressable at a pre-set address. A bus master transmits a new address and an identification to the bus device. The bus device compares the transmitted identification with an identification that has been stored in the bus device and assumes the transmitted new address, if the transmitted identification corresponds with the identification that has been stored in the bus device. The bus device is then addressable at the new address.
