  8. Meeting Tone • PLEASE Bring your Engineer Mentality and Technologist Attitude • Please keep a Positive Attitude • Please check your Ego and Politics at the door. –Jon Rosdahl former HTSG Chair C. Wright, Azimuth Systems

  9. Review IEEE/802 & 802.11 Policies and Rules • Study Group: Everyone Votes. • All 802 policies apply • All 802.11 policies apply • Submissions must meet document format criteria. • All Study Group voting requires 75% consensus. C. Wright, Azimuth Systems

  10. IEEE-SA Standards Board Bylaws on Patents in Standards • 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. Approved by IEEE-SA Standards Board – December 2002 C. Wright, Azimuth Systems

  11. Inappropriate Topics for IEEE WG/TG/SG Meetings • Don’t discuss licensing terms or conditions • Don’t discuss product pricing, territorial restrictions or market share • Don’t discuss ongoing litigation or threatened litigation • Don’t be silent if inappropriate topics are discussed… do formally object. If you have questions, contact the IEEE Patent Committee Administrator at patcom@ieee.org Approved by IEEE-SA Standards Board – December 2002 C. Wright, Azimuth Systems

  12. Study Group Attendance • Attendance must be taken in study groups • 802 rules • Please sign in to the sheet being passed around • Don’t need contact info, don’t need time when attended • Just sign the sheet once during the week Thank you! C. Wright, Azimuth Systems

  13. A Friendly Reminder… • Don’t forget to log your attendance! • www.802wirelessworld.com • Attendance server problems? • Talk to Harry Worstell C. Wright, Azimuth Systems
