Bluetooth® SIG Liaison Report

Notice: This document has been prepared to assist IEEE 802.11. It is offered as a basis for discussion and is not binding on the contributing individual(s) or organization(s). The material in this document is subject to change in form and content after further study. The contributor(s) reserve(s) the right to add, amend or withdraw material contained herein.

Release: The contributor grants a free, irrevocable license to the IEEE to incorporate material contained in this contribution, and any modifications thereof, in the creation of an IEEE Standards publication; to copyright in the IEEE’s name any IEEE Standards publication even though it may include portions of this contribution; and at the IEEE’s sole discretion to permit others to reproduce in whole or in part the resulting IEEE Standards publication. The contributor also acknowledges and accepts that this contribution may be made public by IEEE 802.11.

Patent Policy and Procedures: The contributor is familiar with the IEEE 802 Patent Policy and Procedures <http:// ieee802.org/guides/bylaws/sb-bylaws.pdf>, including the statement "IEEE standards may include the known use of patent(s), including patent applications, provided the IEEE receives assurance from the patent holder or applicant with respect to patents essential for compliance with both mandatory and optional portions of the standard." Early disclosure to the Working Group of patent information that might be relevant to the standard is essential to reduce the possibility for delays in the development process and increase the likelihood that the draft publication will be approved for publication. Please notify the Chair [email protected] as early as possible, in written or electronic form, if patented technology (or technology under patent application) might be incorporated into a draft standard being developed within the IEEE 802.11 Working Group. If you have questions, contact the IEEE Patent Committee Administrator at <[email protected]>.

Future of Bluetooth Wireless Technology

• Expect to ship 2 Billion devices in 2011– Ultra Low Power devices

– Suitable for high speed applications of digital imaging, music, and video transfer between portable devices and fixed devices.

– 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 link idled when operation completed

GENERIC ALT MAC/PHY ARCHITECTURE

• The AMP architecture modifies the standard Bluetooth architecture by enabling multiple alternate radios under L2CAP– Discovery, connection set up and low

power connections still use the 2.4GHz radio

– The new AMPs are used as high speed data channels

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 (reference IEEE Std 802.11-2007)

• Enable high-speed use cases

• Create market that may 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)

• No changes envisioned for IEEE Std 802.11™ -2007 for use as a Bluetooth Alternate MAC/PHY

• Would like to see alignment of IEEE standard with WFA certification program to simplify product development.

• Possible collaboration with IEEE 802.11 on methods for co-location of Bluetooth wireless technology, IEEE 802.11, and Licensed Broadband Radios (LBR) operating in the 2.3 or 2.5 GHz band (e.g., WiMAX (IEEE 802.16e), LTE, UMB (IEEE 802.20)).
