1. doc.: IEEE 802.11-11/0659r1 Submission May 9, 2011 Fei Tong, CSRSlide 1 Reference waveform generator for 11ac: Status Update 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, 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: 2011-05-09 Authors:

3. doc.: IEEE 802.11-11/0659r1 Submission May 9, 2011 Fei Tong, CSRSlide 3 History Presentation first made in March 2011 in Singapore –Document number IEEE 802.11-11/0295r3 –Reference model as an informative part of the 11ac standard Very favourable straw poll results –#1 Are you in principle in favour of providing a sample transmitter tool, as an informative annex to the 11ac standard (same as 11n)? Yes – 37, No – 1, Abstain – 4 –#2 Do you agree with the framework of the model we have presented and using it as a basis for the 11ac reference transmitter model? Yes – 26, No – 1, Abstain - 7

5. doc.: IEEE 802.11-11/0659r1 Submission May 9, 2011 Fei Tong, CSRSlide 5 Current Model Status Reference model (with User Guide) first uploaded on 8 April 2011 –Document number IEEE 802.11-11/0517 Cross-checked with several interested parties (Special thanks!) –Sigurd Schelstraete (Quantenna) –Meir Shahar and Greg Lerner (TI) –Ken Voelker and Pete Cain (Agilent) Latest version updated on 5 May 2011

6. doc.: IEEE 802.11-11/0659r1 Submission May 9, 2011 Fei Tong, CSRSlide 6 Pre-motion 1 Do you support adding the reference transmitter model described in document IEEE 802.11-11/0517 as an informative annex to the 11ac standard (e.g. as a reference link to document 11/0517)? Yes No Abstain Passed with no objections.
