Abstract: Wireless devices, transmitters, systems and methods are provided that have a narrow band signaling channel and a wide band channel, for example an OFDM channel. In order to save power, the wireless device is nominally powered down with the exception of a receiver specific to the narrow band signaling channel. Once instructed to do so over the narrow band signaling channel, the wireless device wakes up the rest of its wide band receive circuitry.
