WLAN PHYSICAL LAYER FRAME FORMAT FOR WLAN

摘要

In a method for generating a data unit according to a first communication protocol, a first field and a second field to be included in a preamble of the data unit are generated. The first field contains one or more information bits of the first set indicating the duration of the data unit and the first field is formatted to allow the receiver device according to the second communication protocol to determine the duration of the data unit. . The second field contains a second set of one or more information bits indicating to the receiver device according to the first communication protocol that the data unit conforms to the first communication protocol. The first field and the second field are modulated by a second communication protocol using a modulation technique specified for the field corresponding to the first field and the second field, respectively.
