1. An apparatus, comprising:

  • a clock circuitry;

    at least one memory; and

    logic for a narrowband communication device, at least a portion of the logic comprised in hardware coupled to the at least one memory and at least one wireless transmitter, the logic configured to;

    determine a first wideband preamble, of a plurality of wideband preambles, each wideband preamble of the plurality of wideband preambles comprising a predefined preamble having a respective legacy signal field (L-SIG) length value associated with a respective length of narrowband packets;

    determine a narrowband packet comprising a narrowband preamble and a narrowband packet data portion;

    increase a clock rate of the clock circuitry to correspond to a first wideband signal bandwidth to generate the first wideband preamble;

    decrease the clock rate of the clock circuitry to correspond to a narrowband signal bandwidth to generate the narrowband packet, the first wideband signal bandwidth greater than the narrowband signal bandwidth; and

    generate a binary-preamble packet comprising the first wideband preamble and the narrowband packet, the first wideband preamble determined based on a length of the narrowband packet and the respective length of narrowband packets associated with the L-SIG length value of the first wideband preamble.
