Data communication method and related apparatus

An access device comprising:

• a processor;
• and
• a non-transitory storage medium coupled to the processor and storing instructions for execution by the processor, the instructions, when executed by the processor, causing the access device to:
• encapsulate a first beacon frame into a first standard protocol data unit that conforms to a first standard;
• encapsulate a second beacon frame into a second protocol data unit that conforms to a second standard;
• and
• broadcast the first protocol data unit and the second protocol data unit,
• wherein the first protocol data unit includes a preamble and a first bearer data including the first beacon frame,
• wherein a guard interval length of the preamble and a guard interval length of the first bearer data is a first guard interval length supported by the access device,
• wherein the second protocol data unit includes a legacy preamble, a high efficiency wireless local area network preamble, and a second bearer data including the second beacon frame, and
• wherein a guard interval length of the legacy preamble is the first guard interval length supported by the access device, and a guard interval length of the second bearer data is a second guard interval length supported by the access device.

A non-transitory computer-readable storage medium storing instructions for execution by a processor of an access device, the instructions, when executed by the processor, causing the access device to:

• encapsulate a first beacon frame into a first protocol data unit that conforms to a first standard;
• encapsulate a second beacon frame into a second protocol data unit that conforms to a second standard;
• and
• broadcast the first protocol data unit and the second protocol data unit,
• wherein the first protocol data unit includes a preamble and a first bearer data including the first beacon frame,
• wherein a guard interval length of the preamble and a guard interval length of the first bearer data is a first guard interval length supported by the access device,
• wherein the second protocol data unit includes a legacy preamble, a high efficiency wireless local area network preamble, and a second bearer data including the second beacon frame, and
• wherein a guard interval length of the legacy preamble is the first guard interval length supported by the access device, and a guard interval length of the second bearer data is a second guard interval length supported by the access device.
