1. An apparatus, comprising:
a memory; and
logic, at least a portion of which is in hardware coupled with the memory, the logic to generate a preamble in a physical protocol data unit (PPDU) to transmit by a transmitter via a wireless channel of a below 1 GHz frequency band, the preamble of the PPDU to comprise a short training field (STF), a long training field (LTF), and a signal field, the signal field to comprise a space-time block coding (STBC) field having a one-bit length, a short guard interval field comprising a bit set to 0 if a short guard interval is not used and set to 1 if a short guard interval is used, and a coding field to designate whether to use binary convolutional coding (BCC) or low density parity check coding (LDPC), a bandwidth (BW) of the PPDU comprising one of: 1 MHz, 2 MHz, 4 MHz, 8 MHz, and 16 MHz, the logic to generate the preamble as a 1 MHz BW preamble and to replicate the STF, the LTF, and the signal field of the 1 MHz BW preamble into two 1 MHz BW preambles to generate a 2 MHz BW preamble for transmission of the PPDU as a 2 MHz BW PPDU.
