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.

Abstract
Communication devices and techniques for facilitating coexistence between networks operating at different bandwidths are described. In one embodiment, for example, an apparatus may include 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 the at least one wireless transmitter, the logic to determine a wideband preamble, determine a narrowband packet comprising a narrowband preamble and a narrowband packet data portion, and generate a binary-preamble packet comprising the wideband preamble and the narrowband packet. Other embodiments are described and claimed.
