Data communication method and related apparatus

An access device, comprising:

• a non-transitory storage medium;
• and
• a processor coupled to the storage medium and configured to:
• encapsulate a beacon frame into a first standard protocol data unit and encapsulate a beacon frame into a second standard protocol data unit;
• the first standard protocol data unit includes a preamble and bearer data;
• and a guard interval length of the preamble and a guard interval length of the bearer data is a first alternative guard interval length supported by the access device in the first standard;
• the second standard protocol data unit includes a legacy preamble, a high efficiency wireless local area network preamble, and bearer data;
• and, a guard interval length of the legacy preamble is the first alternative guard interval length supported by the access device in the first standard, and a guard interval length of the bearer data is a second alternative guard interval length supported by the access device in the second standard;
• and
• broadcast the first standard protocol data unit and the second standard protocol data unit.

A non-transitory computer-readable storage medium, wherein the medium is configured to store instructions for execution by a processor of an access device to perform a data communication method comprising:

• encapsulating a beacon frame into a first standard protocol data unit and encapsulating a beacon frame into a second standard protocol data unit;
• and
• the first standard protocol data unit includes a preamble and bearer data;
• and a guard interval length of the preamble and a guard interval length of the bearer data is a first alternative guard interval length supported by the access device in the first standard;
• the second standard protocol data unit includes a legacy preamble, a high efficiency wireless local area network preamble, and bearer data;
• and, a guard interval length of the legacy preamble is the first alternative guard interval length supported by the access device in the first standard, and a guard interval length of the bearer data is a second alternative guard interval length supported by the access device in the second standard;
• broadcasting the first standard protocol data unit and the second standard protocol data unit.
