Abstract
The disclosure is directed to a system and methods for waking-up a wireless receiver on a wireless network. The method includes the steps of: listening, by the wireless receiver, for signals in a predetermined frequency band periodically and decoding a wake-up key; validating the wake-up key by correlating the wake-up key with values stored in a memory using a first processing device; if the wake-up key is validated, decoding at least one PHY Protocol Data Unit (PPDU) and checking the value of one or more bits of the PPDU to validate the decoded PPDU as a wake-up PPDU; if the wake-up packet is validated, decoding a wake-up address and comparing the wake-up address to the station (STA) wake-up address; if the decoded wake-up address matches the STA wake-up address, powering-up a second processing device and confirming wake-up by exchanging an encrypted frame with Access Point (AP).
