摘要：
A method of low power discovery (LPD) that extends the battery life of a portable Wi Fi device or portable media player (PMP) using IEEE 802.11 interface by ensuring that PMP host processor is only on when in designated 802.11 coverage or when needed by a user, by employing probabilistic channel scanning-comprising: A) bringing an AT host equipped with an 802.11 interface to an advanced configuration and power interface (ACPI) state S3 or equivalent sleep state, and prior to said device or media player going to sleep; and B) programming the 802.11 WLAN to wake up based on a predetermined trigger logic.
