Abstract
In a method for generating a physical layer (PHY) data unit for transmission via a communication channel, a first preamble portion and a data portion of the data unit is generated. The first preamble portion includes one or more long training fields. The first preamble portion and the data portion are modulated using a plurality of orthogonal frequency division multiplexing (OFDM) symbols. Symbol duration of each OFDM symbol is at least 8 μs. The data unit is generated to include the plurality of OFDM symbols.
