Abstract
Devices, systems and methods generate a packet including a first preamble and a narrow band packet. Embodiments assign a first frequency band to the first preamble and assign a second frequency band to the narrow band packet. The second frequency band is a first sub-band of the first frequency band. Embodiments transmit the packet by transmitting the first preamble across the first frequency band and transmitting the narrow band packet across the second frequency band. The narrow band packet includes a second preamble and narrow band packet data.
