Abstract
A first communication device transmits a first packet that includes a wakeup request packet configured to prompt a wakeup radio at a second communication device to prompt a network interface device of the second communication device to transition from a low power state to an active state. The first communication device measures a delay period after an end of transmission of the first packet. The delay period corresponds to a time required for the network interface device of the second communication device to transition from the low power state to the active state. After at least the delay period, the first communication device transmits the second packet.
