Abstract: A software defined radio type radio receiver is used in an environment that is self-sufficient in energy. The radio receiver has a receiving device, which receives the data in the form of a data packet or a portion thereof or a data stream at a certain data rate, and provides the data for further data processing. Wherein in an operating mode, the data is diverted at the receiving device and supplied to a microcontroller at a sampling rate which preferably can be defined. The microcontroller decimates the data by selecting a subset from the set of samples, and the microcontroller buffers in a memory and provides for further processing the decimated data.

Abstract: A method transmits data via radio between a node and a base station with bidirectional radio transmission-based operation. The base station has a communication module with a first frequency transmitter. The node has a communication module with a first frequency transmitter and a second frequency transmitter with a frequency lower than the first frequency transmitter.

The communication module of the base station transmits data in the downlink to the communication module of the node by virtue of a radio telegram being split into two data packets transmitted successively with a temporal spacing. The transmission time and/or the carrier frequency of at least one of the data packets is corrected.

Abstract: A method provides communication between a meter and a flying device. The meter records consumption data. The flying device performs flight movements to a prescribed target position of the meter. Radio signals are received by a reception device and information is ascertained, relating to the transmission quality of a radio channel, based on the received signals. A poor transmission quality, satisfaction of which is dependent on the quality of the information, results in the reception of received signals and the ascertainment of the information being repeated after a communication protocol for communication with the meter has been changed, a position of the flying device being altered and/or a directivity of the reception device is altered until the transmission quality or a termination condition is satisfied. Upon having a satisfactory quality condition, meter information is captured and a message for controlling the operation of the meter is sent to the meter.

Abstract: 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.

Abstract: To optimally receive smart meter control messages transmitted by a concentrator, in a meter having a transceiver for bidirectional data interchange, despite its minimal resources, a current modulation reference frequency which is subject to drift is shifted by the instantaneous frequency difference between the current transmitter-side reference frequency and the current transceiver-side reference frequency in the concentrator. Therefore, the current reference frequencies correspond in the downlink without having to intervene in the meter. This frequency difference in the concentrator is obtained by comparing the current receiver-side demodulation reference frequency with the current transmitter-side reference frequency, and the current transceiver-side reference frequency, on the other hand, from messages from the transmitter of the concentrator and from the transceiver of the meter which are received using the receiver of the concentrator.
