Systems and methods for scanning for a wake up packet addressed to a wireless device

摘要

A system and method for wireless waking computing devices over a computer network is provided. A signal is broadcast over the network that includes one or more device specific wake-up data sequences. Each device specific wake-up data sequence includes multiple iterations of the hardware address of the wireless network card associated with that device. While in a reduced power or “sleep mode”, the wireless network card monitors wireless channels for packets containing a wake-up data sequence. If a wake-up data sequence is received, the sequence is matched against the hardware address information for that network card. If a match is determined, the network card sends a signal to the computing device causing full system power to be restored. A signal is sent to the network confirming that the device has been successfully woken from the sleep mode.

主权项

1. A method comprising:
scanning for a wake-up packet addressed to a wireless device, wherein the wake-up packet is configured to cause the wireless device to initiate a switch from operating in a first power mode to operating in a second power mode, wherein the scanning is performed for a predetermined period of time; and ceasing to scan for the wake-up packet addressed to the wireless device in response to not receiving the wake-up packet after the predetermined period of time has elapsed.
