Abstract
In a method for generating a null data packet (NDP) sounding packet for transmission via a communication channel, a signal field and one or more long training fields are generated. The signal field and the long training fields are modulated using a plurality of orthogonal frequency division multiplexing (OFDM) symbols. Symbol duration of each OFDM symbol of the plurality of OFDM symbols is at least 8 μs. The NDP sounding packet is generated to include the plurality of OFDM symbols. The NDP sounding packet omits a data payload portion.
