In one embodiment, when conditions are observed a wireless device keeps its radio circuitry powered down during a designated transmission window orchestrated by an associated Access Point (AP) for forwarding buffered broadcast and multicast data to reduce power consumption by the wireless device. The wireless device then temporarily powers up its radio circuitry to receive a beacon outside the designated transmission window. When the received beacon indicates buffered data, the wireless device transmits a request for a unicast transmission of the buffered data from the AP. |
