1. A method of operating a wireless network, the method including:
- sending a wakeup tone;
periodically waking up from a sleep mode to listen for the wakeup tone;
upon receiving the wakeup tone, listening for at least one second tone, the at least one second tone being one of (i) a tone in a frequency different from the wakeup tone and (ii) a pattern of tones including at least one frequency different from the wakeup tone; and
upon receiving the at least one second tone, performing an action based on the at least one second tone.

10. A wireless network, comprising:
a receiver node that includes; an arrangement to receive a plurality of tones each at a predefined frequency; an energy storage arrangement; and a control arrangement to operate the receiver node in a sleep mode to conserve energy, wherein the receiver node is configured to periodically wake up from the sleep mode to listen for a wakeup tone, and upon receiving the wakeup tone, listening for at least one second tone, the at least one second tone being one of (i) a tone in a frequency different from the wakeup tone and (ii) a pattern of tones in at least one frequency different from the wakeup tone. - View Dependent Claims (11, 12, 13)
