Abstract
A method and apparatus for power conservation is provided for a multi-mode wireless communication device () capable of operating in a plurality of networks, each of the plurality of networks having a network signal with predetermined spectral characteristics. The wireless communication device () includes a variable bandwidth signal detector (), a threshold detector (), and a controller (). The variable bandwidth signal detector () receives radio frequency (RF) signals and defines a detection bandwidth for signal detection. The threshold detector () is coupled to the variable bandwidth signal detector () and detects a network signal within the RF signals in response to determining whether a signal is present within the detection bandwidth having a signal strength greater than a predetermined signal strength. The controller () is coupled to the variable bandwidth signal detector () and the threshold detector () and offsets a center of the detection bandwidth of the variable bandwidth signal detector () in response to the predetermined spectral characteristics of the network signal.
