Claim 6:
7. The communication device of claim 6, wherein the one or more IC devices are further configured to:
as part of generating the PHY preamble to include the plurality of additional OFDM symbols corresponding to the non-legacy signal field:
generate the PHY preamble to include a third OFDM symbol corresponding to the non-legacy signal field as part of, and
generate the PHY preamble to include a fourth OFDM symbol corresponding to the non-legacy signal field; and

as part of generating the plurality of additional OFDM symbols to use the second modulation pattern:
generate the third OFDM symbol using binary phase shift keying (BPSK) modulation, and
generate the fourth OFDM symbol using quadrature binary phase shift keying (Q-BPSK) modulation to signal that the PHY data unit is generated according to the range extension PHY mode.
