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, 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 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.http:// ieee802.org/guides/bylaws/sb-bylaws.pdfstuart.kerry@philips.compatcom@ieee.org Date: 2005-07-19 Authors:

3. Doc.: IEEE 802.11-05/669r2 Submission July 2005 Charles R. Wright, Azimuth Systems, Inc.Slide 3 6. Patents 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. This assurance shall be provided without coercion and prior to approval of the standard (or reaffirmation when a patent becomes known after initial approval of the standard). This assurance shall be a letter that is in the form of either a) A general disclaimer to the effect that the patentee will not enforce any of its present or future patent(s) whose use would be required to implement the proposed IEEE standard against any person or entity using the patent(s) to comply with the standard or b) A statement that a license will be made available without compensation or under reasonable rates, with reasonable terms and conditions that are demonstrably free of any unfair discrimination This assurance shall apply, at a minimum, from the date of the standard's approval to the date of the standard's withdrawal and is irrevocable during that period. IEEE-SA Standards Board Bylaws on Patents in Standards Approved by IEEE-SA Standards Board – December 2002

4. Doc.: IEEE 802.11-05/669r2 Submission July 2005 Charles R. Wright, Azimuth Systems, Inc.Slide 4 At the December 2004 meeting of the IEEE-SA Standards Board Patent Committee (PatCom), Paul Nikolich (Chair, 802) on behalf of Stuart Kerry (Chair, 802.11)led discussion on an agenda item titled 'Discussion of P802.11n Protest'. You noted that some members of the P802.11n working group requested a clarification of policy from PatCom regarding what would be acceptable to discuss during a working group technical presentation, regarding patent information/statements. PatCom is charged with providing oversight for the use of patents and patent information in IEEE Standards. PatCom is also charged with reviewing patent information submitted to the IEEE Standards Department to determine conformity with patent procedures and guidelines. As empowered by the IEEE-SA Standards Board Bylaws, PatCom has reviewed the information presented and rendered its decision by interpreting the policies and procedures of the IEEE and the IEEE-SA relevant to the issues. In regards to the presentation of information to a standards development group, PatCom has decided the following: 1. After a patent letter of assurance (LoA) has been accepted by PatCom, it is allowable for a presenter to state that an LoA has been filed by a Patent Holder, accepted by PatCom, and listed in the online listing of LoAs at http://standards.ieee.org/db/patents/index.html Anyone seeking a copy of the accepted LoA should contact the PatCom Administrator. 2. Discussion of the content of accepted, submitted, or proposed LoAs is prohibited. 3. Discussion of licensing terms and conditions is prohibited. Patent Committee Ruling – January 6, 2005

16. Doc.: IEEE 802.11-05/669r2 Submission July 2005 Charles R. Wright, Azimuth Systems, Inc.Slide 16 “First list of metrics” I realized that slide 6 of 11-05/378r3 contained a list of metrics These metrics have been discussed in presentations in the past Therefore, let’s call this our “first list of metrics” and then assign individuals to create proposals It seemed to make sense to assign the authors of these original presentations to be those to create the proposals Naturally, we are all volunteers, but we’re not going to get a worthwhile draft without proposals! The assignees are welcome to develop a proposal that addresses the metric, or to let us know if it turns out the metric is not actually useful
