Outline Bluetooth advances in Windows Vista Partner slides: CSR Bluetooth features post Windows Vista Partner slides: Dell Inc Call to action

Core Stack Enhancements For Windows Vista Synchronous connection oriented links Channel avoidance Radio class driver enabled by Microsoft OS descriptors Pre-boot HID support for Bluetooth keyboards and mouse

Extensibility Improvements For Windows Vista Logical link control adaptation protocol (L 2 cap) and Service discovery protocol (SDP) interfaces Synchronous connection oriented links (SCO) interfaces Device installation extensibility Installation based on Bluetooth host controller (local) Installation interfaces for Server-side profiles

Profiles On Windows Vista Silicon agnostic headset and handsfree profiles available via Microsoft Update on Windows Vista Also available to PC OEMs for factory preinstall Stereo audio profiles (A 2 DP, AVRCP) available on Windows native stack via Bluetooth silicon vendors Microsoft update for stereo audio profiles currently being investigated Other profiles (FTP, BIP, BPP) available via Bluetooth silicon vendors

New Logo Requirements For Bluetooth Radios On Windows Vista Must support Bluetooth 2. 0 + EDR specifications as defined by the Bluetooth SIG Microsoft plans to upgrade stack qualification to Bluetooth 2. 0 + EDR Must support synchronous connection oriented links as defined by the Bluetooth SIG

Value Proposition of Bluetooth on Windows Vista Consumers Improved sync experience Better coexistence with 802. 11 “Ultimate” Headset experience Support for new Bluetooth radios Support for high growth profiles

Value Proposition of Bluetooth on Windows Vista OEMs and device vendors Extensible platform and reduced time to market for partners developing custom solutions Improved device coverage by Microsoft OS descriptors based radio class driver Support for high growth profiles Qualification update to Bluetooth 2. 0 + EDR

CSR Vista Profile Pack Adds profiles & features built on Microsoft Bluetooth APIs Stereo Audio A 2 DP & AVRCP Profiles Works with both HID & Mono Audio Additional Vo. IP clients for Mono Audio Skype Pre-boot HID Allows mouse/keyboard connection in BIOS

CSR’s Experience APIs are straight forward to use Rich interface with good granularity BRB interface follows familiar URB pattern Limitations: No RFCOMM access from kernel mode No API for Qo. S (bandwidth management & allocation) Error return codes for kernel mode APIs give limited information

Post Windows Vista Feature Considerations Core stack enhancements Simplified pairing Standardized pre boot HID solution Sniff Sub-rating Quality of service User experience Revamp of overall user experience based on Simplified pairing Improved dial-up networking and Internet connection setup experience

Post Windows Vista Feature Considerations Inbox inclusion of high growth profiles Headset and Handsfree profile Stereo audio profiles (A 2 DP, AVRCP) Other profiles which customers request Additional developer support New samples for SDK Function discovery integration (consistent APIs to discover Bluetooth devices)

Post Windows Vista Logo Requirements & Considerations Bluetooth 2. 0 + EDR requirements for HID, Printers and Headsets Microsoft OS descriptors requirement for Bluetooth radios Logo program for Bluetooth headset devices
