1. A kind of 1. data transmission method, it is characterised in that including:

  • Data to be transmitted is divided into multiple data packets by initiator;

    Initiate direction recipient and send synchronization request, the synchronization request carries the factor for calculating frequency point sequence;

    Initiator is utilized respectively the factor with recipient and identical frequency point sequence is calculated;

    The transmission frequency point of initiator and recipient using the frequency point sequence as the multiple data packet;

    Detect the corresponding channel of frequency point to be used and whether there is signal interference;

    If presence signal is disturbed, abandon carrying out data transmission using the channel, and reselect from the frequency point sequenceFrequency point to be used and/or time slot to be used are transmitted the data packet;

    If signal interference is not present, carried out data transmission using the channel;

    If it is determined that the recipient does not receive data packet, frequency point to be used is reselected from the frequency point sequence to describedData packet is transmitted again.
