1. A system for saving power in a wireless network having two or more stations, at least some of the stations associated with the wireless network comprising: a partial address associated with a subset of the destination MAC address of a receiving station in the wireless network; and a PHY layer filtering protocol configured to generate and write the partial address into a PHY layer header portion of a frame of a sending station in the wireless network, or configured to read the partial address from the PHY layer header portion of a frame of the receiving station upon receipt of a data frame, wherein a plurality of receiving stations having the PHY layer filtering protocol associated with the wireless network determine at the PHY layer whether the partial address received in the PHY layer header portion of a received frame matches an internal partial address, and wherein the plurality of receiving stations reject the received frame if no match is found or the partial address in the received frame is a predetermined value.
