Transmission of wide bandwidth signals in a network having legacy devices

摘要

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.

1. A method for transmitting a wireless communication, the method comprises:
generating a first legacy frame in accordance with a legacy version of the IEEE 802.11 protocol; generating a second legacy frame in accordance with the legacy version of the IEEE 802.11 protocol; transmitting the first legacy frame and the second legacy frame in a current channel having a wide channel bandwidth in accordance with a current version of the IEEE 802.11 protocol; and wherein the first legacy frame and the second legacy frame are duplicate frames, wherein the first legacy frame includes a first legacy preamble portion having a first legacy short training sequence and a first legacy long training sequence and the second legacy frame includes a second legacy preamble portion having a second legacy short training sequence and a second legacy long training sequence.
