1. A method comprising:
- providing an access point in a wireless network with wake packet filtering instructions;
enabling an access point to wirelessly receive a packet; and
enabling said access point to determine, using said wake packet filtering instructions, whether to awaken a host.

Abstract
An access point in a wireless network may receive packets over a wired network. The access point may be provided with instructions from the host to determine when to awaken the host from a reduced power consumption state in response to the receipt of a packet. Thus, the access point can enforce wake packet filtering rules while the host is maintained in a reduced power consumption state. This may reduce the power consumption of the host by avoiding the unnecessary awakening of the host every time a packet of little importance arrives over the network.

11. An article comprising a computer-readable medium storing program instructions that, if executed, enable a processor-based system to perform the steps of:
-
providing distribution services; receiving wake packet filtering instructions from a host before the host transitions to a reduced power consumption state; receiving a wireless packet; and applying said wake packet filtering instructions to said packet to detennine whether to awaken the host. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)
