The method provided by an embodiment includes: selecting two channels as a prescribed channel and a spare channel; dividing a CFP of a superframe into three SCFPs, where a second SCFP is used to re-transmit data that a node fails to transmit in a first SCFP, a third SCFP is used to re-transmit data that the node fails to transmit in the second SCFP, and a timeslot position of each node in the first SCFP is the same as in the second SCFP; broadcasting a beacon frame on the prescribed channel in a beacon period of the superframe, where the beacon frame includes channel selection information and timeslot division information; receiving data from the node; and transmitting an acknowledgement frame."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Data transmission method and apparatus","description":"The disclosed is a data transmission method and apparatus configured to establish a frequency hopping-retransmission mechanism in a CFP of a superframe and switch a channel accordingly.
