Abstract
Embodiments may comprise an orthogonal frequency division multiplexing (OFDM) system operating in the 1 GHz and lower frequency bands. In many embodiments, physical layer logic may implement a new preamble structure with a new signal field. Embodiments may store the preamble structure and/or a preamble based upon the new preamble structure on a machine-accessible medium. Some embodiments may generate and transmit a communication with the new preamble structure. Further embodiments may receive and detect communications with the new preamble structure.
Claims22
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.
A non-transitory machine-accessible product comprising code, the code to cause a processor to perform operations when executed by the processor, the operations 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.
