Abstract
A method for reducing power consumption in wireless devices includes establishing a wireless link between a local device and a remote device and sending a message to the remote device across the wireless link. The message may specify a communication schedule. Communications between the local device and the remote device are performed according to the communication schedule. The communication schedule specifies time periods in which data is not transferred between the local device and the remote device, and during such time periods at least one of the local device or the remote device enters a low power mode.
Claims19
A method for reducing power consumption in wireless devices, the method comprising:
- generating a communication schedule in a local device based on a profile stored in the local device, wherein the communication schedule specifies (i) a first duration of time during which data is transferred between the local device and a remote device, and (ii) a second duration of time during which data is not transferred between the local device and the remote device, and wherein the profile indicates (i) a start time, (ii) a duration, and (iii) a periodicity for communicating between the local device and the remote device using a wireless protocol at a close range;
- establishing a wireless link between the local device and the remote device;
- sending the communication schedule in a message to the remote device across the wireless link, wherein the message is a pre-existing message of the wireless protocol used to communicate interference present in an operating environment of the local device and the remote device;
- and
- communicating between the local device and the remote device according to the communication schedule,
- wherein, during the second duration of time, at least one of the local device or the remote device enters a low power mode.
A wireless device comprising:
- a wireless transmitter;
- a wireless receiver;
- and
- a controller configured to
- generate a communication schedule in the wireless device based on a profile stored in the wireless device, wherein the communication schedule specifies (i) a first duration of time during which data is transferred between the wireless device and a remote device, and (ii) a second duration of time during which data is not transferred between the wireless device and the remote device, and wherein the profile indicates (i) a start time, (ii) a duration, and (iii) a periodicity for communicating between the wireless device and the remote device using a wireless protocol at a close range;
- use the wireless transmitter and the wireless receiver to establish a wireless link between the wireless device and the remote device;
- and
- using the transmitter, send the communication schedule in a message to the remote device across the wireless link, wherein the message is a pre-existing message of the wireless protocol used to communicate interference present in an operating environment of the wireless device and the remote device,
- wherein the communication occurs in accordance with the communication schedule, and
- wherein, during the second duration of time, at least one of the wirelesses device or the remote device enters a low power mode.
