Claim 1:
2. The method of claim 1, wherein:
generating the PHY preamble to include the plurality of additional OFDM symbols corresponding to the non-legacy signal field comprises:
generating the PHY preamble to include a third OFDM symbol corresponding to the non-legacy signal field, and
generating the PHY preamble to include a fourth OFDM symbol corresponding to the non-legacy signal field; and

generating the plurality of additional OFDM symbols to use the second modulation pattern comprises:
generating the third OFDM symbol using binary phase shift keying (BPSK) modulation, and
generating 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.
