Abstract
A data communication method and a related apparatus are provided, and the data communication method includes: constructing, by an access device, a beacon frame, where the beacon frame includes a newly added field, and the newly added field represents multiple data guard interval lengths supported by the access device; and broadcasting, by the access device, the beacon frame, so that a terminal selects an available guard interval length matching a data guard interval length supported by the terminal from the beacon frame, and performs data communication with the access device by using the available guard interval length. By using the present invention, data communication between the access device and the terminal can be implemented when the access device supports multiple data guard interval lengths.
