FIELD: communication equipment.
SUBSTANCE: invention relates to a wireless network with spreading and frequency hopping for IoT applications. For this purpose, the network comprises mobile devices with non-synchronized local clocks, which transmit, including in the preamble portion, a plurality of sync bytes, each of which is combined with at least one serial index sample. Frequency hopping frequencies whereon sync words are transmitted differ from each other.
EFFECT: technical result consists in improvement of quality of communication due to detection and synchronization of signals, in spite of unavoidable mismatches of frequencies and collision.
