22 Claims

1. An apparatus, comprising:

memory; and

a processor coupled with the memory 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 processor to generate the preamble as a 1 MHz bandwidth (BW) preamble and to replicate the STF, the LTF, and the signal field of the 1 MHz BW preamble to generate a 2 MHz BW preamble for transmission of the PPDU as a 2 MHz BW PPDU, a 4 MHz BW preamble for transmission of the PPDU as a 4 MHz BW PPDU, an 8 MHz BW preamble for transmission of the PPDU as a 8 MHz BW PPDU, or a 16 MHz BW preamble for transmission of the PPDU as a 16 MHz BW PPDU; and

cause transmission of the PPDU.
