Abstract
A mobile device that comprises a main receiver and a wake-up receiver is operated by periodically attempting to receive a first signal that is configured for receipt by the wake-up receiver. For each attempt, a detection result is generated that indicates whether the first signal was received with a signal quality that satisfies a predetermined minimum quality criterion. One or more of the detection results are used as a basis for deciding whether or not the wake-up receiver is within range of an access point. An operation of the mobile device is adjusted in response to a decision that the wake-up receiver is not within range of the access point.
