Abstract
A wireless device may include processing circuitry that is configured to process a preamble of a packet, the preamble comprising a legacy portion comprising a legacy signal field (L-SIG) and a subsequent portion comprising a non-legacy signal field. The processing circuitry may be further configured to determine whether a symbol of the non-legacy signal field is modulated using binary phase shift keying (BPSK) or modulated using quadrature binary phase shift keying (OBPSK). The processing circuitry may be further configured to process the subsequent portion of the packet in accordance with a first packet format if the symbol of the non-legacy signal field is modulated using OBPSK, and to process the subsequent portion of the packet in accordance with a different packet format if the symbol of the non-legacy signal field is modulated using BPSK.
