Abstract
One illustrative example includes wireless device having a first wake-up receiver and a second wake-up receiver. The first wake-up receiver can detect a first wake-up signal within a first group of wireless signals and responsively activate the second wake-up receiver. The second wake-up receiver can then detect a second wake-up signal within a second group of wireless signals and responsively activate a transceiver, where the transceiver is usable to engage in bidirectional communication with a remote device.
