An access point transmits buffered broadcast and/or multicast data that is destined for two or more wireless client devices that are in a power-save mode and are associated concurrently with the access point following transmission of a beacon frame in a beacon signal that has a IEEE 802.11 delivery traffic indication message, IEEE 802.11 DTIM, to indicate the presence of the buffered data, and transmits the buffered data following transmission of another beacon frame in the beacon signal that has a IEEE 802.11 DTIM to indicate the presence of the buffered data. |
