Patent ID: 8625690

Claim:
An apparatus for wireless communication, comprising: a receiver configured to receive a wireless signal comprising a packet, at least a portion of the wireless signal configured to be received over a bandwidth lower than or equal to 1.25 MHz, wherein the packet is formed from at least one orthogonal frequency-division multiplexing (OFDM) symbol comprising thirty-two tones, the thirty-two tones corresponding to frequency subcarriers within the bandwidth, and wherein the thirty-two tones of the at least one OFDM symbol are allocated as: twenty-four data tones, two pilot tones, five guard tones, and one direct current (DC) tone; and a processor configured to evaluate the wireless signal, the processor comprising a transform module configured to convert the at least one OFDM symbol into a frequency domain signal using a thirty-two point mode: wherein the packet comprises a preamble portion and a payload portion, and wherein the preamble portion of the packet comprises a short training field (STF), a long training field (LTF), and a signal (SIG) field, wherein the SIG field comprises at least one of a space-time block coding (STBC) sub-field having a length of 1 bit, a modulation and coding scheme (MCS) sub-field having a length of less than 7 bits, and a cyclic redundancy check (CRC) sub-field having a length of less than 8 bits.
