Abstract
A first communication device generates a first portion and a second portion of a wakeup radio (WUR) wakeup packet. The first portion of the WUR wakeup packet corresponds to a wireless local area network (WLAN) legacy preamble, and spans a first frequency bandwidth. The second portion of the WUR wakeup packet spans a second bandwidth that is less than the first bandwidth, and is configured to cause a WUR of a second communication device to cause a WLAN network interface device of the second communication device to transition from a low power state to the active state. Generating the second portion of the WUR wakeup packet includes i) generating a sync portion having a plurality of sync symbols, and ii) generating a wakeup packet body. The first communication device transmits the WUR wakeup packet.
