Abstract
This disclosure provides a method and apparatus for a staged wake-up of a wireless device. The wireless device may include a wireless wake-up receiver and a communication transceiver. The wireless device may begin operations in a low-power mode. The wireless wake-up receiver may identify radio-frequency (RF) activity and transition operation of the wireless device from the low-power mode to an active power mode when RF activity is identified. In some implementations, RF activity is identified when an energy pattern of a received RF signal is matched to an energy pattern associated with a known communication protocol.
