                       Bluetooth Market

 • Installed base of Bluetooth enabled products reached
   1 Billion devices in November of 2006.
 • Every week, 13 million Bluetooth units are shipped.
   (~675 million per year or 21 every second)
 • Every working day, more than five new Bluetooth
   enabled products are qualified. (~1300 per year)

 • Broad surveys have shown that the Bluetooth brand is
   recognized by more than 75% of respondents world-
   wide. (Millward Brown internet survey for Bluetooth SIG: Bluetooth.org)

             Bluetooth Qualification Program
 • Bluetooth Qualification requires certain testing
   standards for all designs and products which use the
   Bluetooth wireless technology.
 • Qualification is a necessary pre-condition of the
   intellectual property license for the Bluetooth wireless
   technology.
 • Qualification is also a necessary prerequisite in order to
   apply the Bluetooth trademark to a design or product.
 • Bluetooth Profile Tuning Suite has been developed as a
   reference test system to ensure Bluetooth
   interoperability.

The Bluetooth Wireless Experience:
• Replaces cables connecting portable and/or fixed devices while
  maintaining high levels of security,
• Robust, low power, low cost solution,
• Any Bluetooth enabled device, almost everywhere in the world,
  can connect to other Bluetooth enabled devices in proximity,
• Bluetooth enabled devices with common profiles work together
  to provide a uniform user experience.

    Future of Bluetooth Wireless Technology

 • Expect to ship 2 Billion devices in 2011
       – Ultra Low Power devices
       – Suitability for high speed applications for digital imaging, music,
         and video transfer
       – Improved interoperability
       – Bluetooth Wireless Experience
 • Bluetooth Alternate MAC/PHY Approach
       – Bluetooth link used to discover peer device, authenticate, discover
         capabilities (e.g., 802.11), and initiate operation
       – 802.11 link enabled and used when higher performance required

              802.11 Alternate MAC/PHY (AMP)
• Bluetooth/802.11 combo chips on the market
• Both technologies in the mobile device
    – Bluetooth in ~50% of mobile phones (500M in 2007)
    – 802.11 only in 20M mobile phones in 2007
• Leverage 802.11 in AMP
• Enable high-speed use cases
• Create market that will increase Bluetooth+802.11 in mobile
  devices to more than 50% of TAM by 2010 (~600M devices)
    – Bluetooth market 1B/year by 2009
    – Current 802.11 market projection only 500M/year by 2009
    – Linkage with Bluetooth could double 802.11 market by 2010

    POTENTIAL COLLABORATION AREAS

•   Liaisons have been identified (IEEE 802.11 and WFA)
•   Evaluate common use cases and market requirements
•   Ensure reasonable levels of coexistence
•   Identify areas where improvements to 802.11 standards are
    desired
