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. A frequency-measuring comparator only needs to be connected upstream and downstream of the demodulator in the concentrator for this purpose.

Claim (Index 1):
A method for bidirectional communication between a data collector having a transmitter and a receiver, on the one hand, and measuring devices having transceivers, on the other hand, by means of a reference frequency, the transceivers, the receiver and the transmitter each having an oscillator with oscillator frequencies being subject to drift and from which the reference frequency to be modulated or demodulated is derived, which comprises the step of:\n shifting a current transmitter-side reference frequency by an instantaneous frequency difference between the current transmitter-side reference frequency and a current transceiver-side reference frequency in the data collector in order to transmit messages from the data collector to a meter.
