Devices, systems and methods for wireless communication system employing overlapping frequency bands

Abstract

According to embodiments, methods, devices and systems can include monitoring all of a first channel for a first monitoring period. After the first monitoring period, monitoring at least one narrow band for at least a first narrow band signal. In response to detecting the first narrow band signal, establishing a network connection over the narrow band, wherein the at least one narrow band has a frequency range less than one half that of the first channel.
