Abstract
A mechanism can be implemented for reducing the power consumption of a wireless radio device in establishing a wireless connection by utilizing a wideband signal to detect a narrowband trigger signal at a potential narrowband trigger frequency. The wireless radio device may operate a wideband receiver to receive an RF signal. Being aware of the potential narrowband trigger frequencies, the wideband receiver may utilize the received RF signal to detect the presence of a narrowband trigger signal at one of the potential narrowband trigger frequencies.
