METHOD AND SYSTEM FOR FREQUENCY CORRECTION WHEN TRANSMITTING DATA IN LPWAN NETWORKS

摘要

FIELD: computer engineering.;SUBSTANCE: invention relates to the computer engineering. Method is realized using a computing device connected to the LPWAN network. Method comprises: determining the actual frequency of the received message as a middle of a given portion of the spectrum, where in the given spectral region, the following condition is met: the message was successfully received in a given portion of the spectrum, the signal quality metric has a maximum value in a given portion of the spectrum compared to all other portions of the spectrum, where the message was also received; calculating expected frequency of radio signal based on data contained in message; determining error of frequency of received radio signal as difference between actual and expected frequencies of signal; generation of message sending frequency based on frequency error of received radio signal.;EFFECT: high spectral efficiency of the data network.;13 cl, 3 dwg
