Abstract
Embodiments herein describe waking up client devices using a physical layer protocol data unit (PPDU) with a preamble extension field with a length that permits the client device to wake up a higher power (or higher capability) radio. In one embodiment, a first portion of a preamble of the PPDU is received at the client device using a lower power (or lower capability) receiver. This triggers the client device to wake up its higher power receiver, which occurs while the client device receives the preamble extension field. At the end of the preamble extension field, the client device then receives the remaining portion of the PPDU using its higher power receiver.
