Battery life extension is effected by ensuring that a PMP host processor is only on when in designated 802.11 coverage or when needed by a user by employing probabilistic channel scanning. The method includes bringing an access terminal host equipped with an 802.11 interface to an advanced configuration and power interface (ACPI) state S3 or an equivalent sleep state prior to the device or PMP going to sleep. Additionally, the method includes programming a Bluetooth (BT) device at the access terminal is to look for a certain IAC (inquiry access code), whereupon finding this IAC, the access sends a Bluetooth inquiry directing an access point (AP) to wake-up the device or PMP via a wake-up packet."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for adaptive bluetooth low power discovery and wake up","description":"Disclosed is a method of low power discovery (LPD) that extends the battery life of a portable Wi Fi device or portable media player (PMP) using an IEEE 802.11 interface.
