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.
