Abstract
Systems, apparatuses, and methods are configured to monitor signals received via a transmission medium by a paging monitor to detect an activity trigger. Systems, apparatuses, and methods are further configured to, in response to detecting the activity trigger, cause, by the paging monitor, a main receiver to transition from an energy conservation mode to an active mode to monitor the transmission medium for data traffic.
Claims20
One or more non-transitory computer-readable media, storing computer-executable instructions that, when executed by a computing device, cause the following to occur:
- switch a computing device from an active mode of data reception operation to an energy conservation mode of data reception operation;
- while the computing device is in the energy conservation mode, monitor an incoming signal for a wakeup signal that contains an address identifying the computing device, and which is sent using a modulation that is orthogonal to a data modulation used on data processed by the computing device during the active mode of data reception operation;
- and
- in response to receiving the wakeup signal, switching the computing device from the energy conservation mode of data reception operation to the active mode of data reception operation.
A method, comprising:
- switching, by a computing device, a data reception operation from an active mode to an energy conservation mode;
- receiving, by the computing device while in the energy conservation mode, an incoming wakeup signal containing an address identifying the computing device, and which uses a modulation that is orthogonal to a data modulation used on data processed by the computing device during the active mode of data reception operation;
- and
- switching the computing device from the energy conservation mode of data reception operation to the active mode of data reception operation in response to receiving the wakeup signal.
A method, comprising:
- determining that a computing device is to be switched from an energy conservation mode to an active mode;
- transmitting a wakeup signal containing an address identifying the computing device;
- and
- modulating the wakeup signal using a modulation that is orthogonal to a data modulation used to transmit data to the computing device when the computing device is in the active mode.
