摘要： A method synchronizes frame counters for protecting data transmissions between a first end-device and a second end-device. The data, in particular data frames, are transferred between the first end-device and the second end-device. The data frames are provided with frame counters to protect the data transfer between the first end-device and the second end-device. The second end-device sends a first data frame to the first end-device. The first data frame contains a marker in its payload data. The first end-device sends back a second data frame as an answer to the second end-device. The second data frame contains a frame counter in the header data, and the second data frame contains the frame counter and the marker in its payload data.

摘要： A method improves antenna matching for a wireless node, preferably of a sensor wireless node and/or actuator wireless node. A radio signal, or at least a portion thereof, is coupled out of the antenna and/or out of the transmit path of the wireless node. The impedance and/or the resonant frequency of the antenna is determined therefrom in the wireless node, and the impedance and/or the resonant frequency of the antenna is adjusted according to the determined impedance and/or resonant frequency by a circuit acting on the antenna.

摘要： A method and a device are used during battery operation of a smart metering meter equipped with a consumption sensor and a transmit clock generator for a radio module for transmitting consumption data packets, in the event of a decreased residual capacity of the battery, to determine if the data packets can be transmitted as previously with the residual capacity over the residual time period until a scheduled battery exchange at the end of a specified operating time period. If not, the transmit power, for example, of the data packets is reduced and/or their transmit clock is extended over the residual period. This determination, along with a control specification, are preferably performed in a concentrator and are transmitted to the meter by using bidirectionally operating radio modules so that computer capacities required therefor need not be retained in each individual meter of a supply area.

摘要： Data are transmitted by radio between a terminal and a data collector. The data collector is intermittently or constantly in receive mode. The terminal attempts, from an idle phase, to set up a communication with the data collector in order to send all or some of the data to the data collector and/or to receive them from the data collector. Alternatively, the data collector attempts to set up a communication with the terminal in order to send all or some of the data to the terminal and/or to receive them from the terminal. The setup of the communication is followed by the terminal sending a message to the data collector and the data collector, after receiving the message, continuing, interrupting and/or terminating the transmission of the data during communication on a basis of the content of the message.

摘要： Data are transmitted and/or received in a communication system by a communication participant, which has a communication device, a microprocessor, and an energy supply. The latter has an electrical variable that changes from an initial value when it supplies the microprocessor and/or the communication device with energy. The microprocessor encodes the data before transmission and/or decodes the data after reception, each using a computing cycle. When the electrical variable changes during the computing cycle, it is interrupted, preferably at any desired point. The encoding and/or decoding are carried out separately during the computing cycle in individual encoding phases in which the value of the electrical variable changes. Regeneration phases for regenerating the electrical variable are provided between and/or within the encoding phases. The duration of a regeneration phase is such that the value of the electrical variable approaches or reaches the initial value during the regeneration phase.

摘要： A method for operating an electronic consumption data module. Consumption data are transmitted via a communication system to a receiver, and different keys are provided for different software authorizations. Command authorizations are defined as software authorizations in the consumption data module. A consumption data module has a memory, a control and/or regulating unit, and a communication device for the consumption data transmission. Different keys are provided for different software authorizations, and the command authorizations are defined as software authorizations in the consumption data module. The consumption data module is operable by the method.

摘要： A control device for a meter device, particularly a water meter device, includes a first data interface for a meter unit measuring a flow of a fluid of the meter device, a second data interface for a reading device communicating with the meter unit through the control device, and a supply interface receiving a combined clock and voltage supply signal for the control device. The control device can assume a read mode in which data at the first data interface can be transmitted by the control device to the second data interface upon receiving a clock and voltage supply signal having a read signal variation. The control device can additionally assume a write mode in which data at the second data interface can be transmitted to the first data interface upon receiving a clock and voltage supply signal with a write signal variation different from the read signal variation.

摘要： A method operates a consumption meter system, in which the consumption of a supply medium by a consumer is determined using a consumption meter. A consumption value is transmitted in the form of data between the consumption meter and a first receiver. The first receiver is assigned to a higher-level supplier and the data are transmitted between the consumption meter and the first receiver via a first data channel. The data are encrypted on the meter side using a first key for transmission via the first data channel. A second data channel is provided for transmitting the data between the consumption meter and a second receiver. The data are encrypted on the meter side by a second key for transmission via the second data channel.

摘要： Mobile units moving in a local network environment and at times in the vicinity of meters of the network, at least temporarily bypass relay functions of a concentrator operated in a stationary manner, if the relay function is not yet available, for instance during construction, for radio communication of data packets of the meter linked into the smart-metering network to a center. The mobile units are persons and/or vehicles with communication devices such as smartphones for long-distance links over the Internet or in the mobile radio standard. The communication devices, as modified mobile radio telephones, receive data packets from meters by using hardware or a software app over a short-distance link to the mobile unit being accidentally temporarily located in the vicinity of the meter. Long-distance communication of packets from mobile unit to center then takes place over the Internet or the mobile radio standard.
