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]>.

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.

New Attendance Recording

• We will continue to use the provisional new attendance recording software– http://newton/ ← note changed URL

• It’s still under development!• It’s unlikely to fail, but if it does, we’ll probably go

back to the paper method (very unlikely)

• NOTE: You must sign in with your contact information before claiming attendance.

• Further note: the number on your badge is different for this event than the past meetings. Be sure to use the number on your badge when you sign in with your contact information

Local Document Server

• There’s a local server that mirrors the documents on www.802wirelessworld.com that’s updated every 15 minutes– ftp://newton/11 (the actual path is sometimes changed so log into the root)

• Please use this server for downloads to conserve bandwidth on our link to the outside world

• For document submissions, use the web interface on www.802wirelessworld.com, as per usual

• One more comment: www.802wirelessworld.com is to be used only for document submissions– Assigning a DCN– Uploading documents for dissemination

• NOTE: USE THE NEW DOCUMENT TEMPLATES!!!– Stuart’s email address has changed in the notice on the title page
