Abstract
The present disclosure provides a data transmission method and apparatus. The method includes: obtaining to-be-transmitted data; putting the to-be-transmitted data into a to-be-transmitted data field with a fourth predetermined number of Bytes in a first predetermined frame format for encapsulation, to obtain a to-be-transmitted data frame, the first predetermined frame format sequentially including a first permeable field, a frame synchronization signal field, an address field, the to-be-transmitted data field, a check field, a first postamble field, and a first predetermined gap field; encoding and modulating the to-be-transmitted data frame in accordance with BPSK, and then transmitting the to-be-transmitted data frame; and demodulating and decoding in accordance with the BPSK to obtain an ACK signal.
