Abstract
A method of operating a wireless communications device may include determining a wake-up time for a receiver using a low frequency clock. Beginning at the wake-up time, the receiver may listen for reception of a packet transmitted from a remote device over a wireless interface. An actual time of reception of the packet transmitted from the remote device may be detected, and a new wake-up time for the receiver may be determined using the low frequency clock and the actual time of reception of the packet.
Claims20
A method of operating a wireless communications device, the method comprising:
- determining a wake-up time for a receiver using a low frequency clock;
- beginning at the wake-up time, listening at the receiver for reception of a packet transmitted from a remote device over a wireless interface;
- detecting an actual time of reception of the packet transmitted from the remote device;
- and
- determining a new wake-up time for the receiver using the low frequency clock and the actual time of reception of the packet.

A wireless communications device comprising:
- a low frequency clock;
- a receiver configured to receive wireless communications from a remote device over a wireless interface;
- and
- a processor coupled to the low frequency clock and coupled to the receiver, wherein the processor is configured to determine a wake-up time for the receiver using the low frequency clock, to use the receiver to listen for reception of a packet transmitted from a remote device over the wireless interface beginning at the wake-up time for the receiver, to detect an actual time of reception of the packet transmitted from the remote device, and to determine a new wake-up time for the receiver using the low frequency clock and the actual time of reception of the packet.
