1. A method comprising:
- determining that a device should enter a sleep mode;
transmitting, in response to determining that the device should enter the sleep mode, a sleep mode configuration request to a remote computing device;
receiving, from the remote computing device, a wake configuration file identifying a first frequency and a predetermined change in a signal characteristic, wherein the predetermined change comprises at least a change in a number of Quadrature Amplitude Modulation (QAM) points received on the first frequency;
setting a component of the device to the first frequency;
configuring the component to detect the predetermined change in the signal characteristic;
detecting, by the component, the predetermined change in the signal characteristic; and
waking the device from the sleep mode in response to detecting the predetermined change in the signal characteristic.

Abstract
Disclosures related to waking a sleeping device while minimizing active components needed to receive a remote wakeup request. In one aspect, devices having an RF tuner, may be configured to detect a digital or an analog signal variation or change in RF signal characteristics. Further, the variation or change may be interpreted as a wakeup signal.

9. A computing device, comprising:
-
a radio frequency (RF) tuner; a signal characteristic detection circuit coupled to an output of the tuner; and a processor, configured to perform the following; determine that a device may enter a sleep mode; receive, from a remote computing device, a wake configuration message comprising a first radio frequency on which a wakeup signal is expected to be received and a predetermined wakeup signal characteristic change; set the RF tuner to the first radio frequency; detect, with the signal characteristic detection circuit, the predetermined wakeup signal characteristic change; and initiate an exit from the sleep mode in response to the detection, wherein the processor is further configured to place the device in a light sleep mode, and to permit waking the device from the light sleep mode in response to both the predetermined wakeup signal characteristic change on the first radio frequency and a locally-generated wakeup signal from a sleep scheduler circuit. - View Dependent Claims (10, 11, 12, 13, 14)

15. A method, comprising:
-
storing, at a computing device, sleep mode configuration data for a plurality of remote devices; receiving a request from a first remote device to enter a sleep mode; identify, in response to receiving the request, in the stored sleep mode configuration data, a wakeup signal characteristic change corresponding to the first remote device, and a wakeup signal frequency, wherein the wakeup signal characteristic change comprises a change in a number of Quadrature Amplitude Modulation (QAM) points received on the wakeup signal frequency; and in response to determining that the first remote device should wake, transmitting the wakeup signal characteristic change on the wakeup signal frequency. - View Dependent Claims (16, 17, 18, 19, 20)
