Abstract:
A method for generating a preamble of a frame for a wide-bandwidth channel wireless communication begins by generating a legacy carrier detect field. The method continues by generating a channel sounding field, wherein the channel sounding field includes a plurality of tones within the wide-bandwidth channel, wherein a first set of the plurality of tones corresponds to tones of a legacy channel sounding field. The method continues by generating a legacy signal field, wherein, in time, the legacy signal field follows the channel sounding field, which follows the legacy carrier detect field.
