`
`In a method for generating a data unit for transmission via a communication channel,
`wherein the data unit conforms to a first communication protocol. a preamble of the
`data unit is generated. The preamble includes a first field having information that
`indicates a duration of the data unit, the first field being formatted such that the first
`field is decodable by a receiver device that conforms to a second communication
`protocol but does not conform to the first communication protocol to determine the
`duration of the data unit based on the first field. Additionally, the preamble is formatted
`such that a portion of the preamble is decodable by a receiver device that conforms to
