determining, by a transceiver, a packet including a header portion and a data portion; and
transmitting, by the transceiver, the packet including the header portion and the data portion, wherein:
the header portion indicates one or more communications parameters used for the data portion of the packet, and
the data portion is used for communication of a number of data bytes at a data rate; and wherein:
the header portion includes a legacy header portion containing a Rate field indicating a legacy data rate value and a Length
field indicating a legacy number of data bytes,
the number of data bytes communicated in the data portion of the packet is different than the legacy number of data bytes
indicated in the legacy header portion of the packet, and
the data rate used in the data portion of the packet is different than the legacy data rate indicated in the legacy header
portion of the packet.
