Welcome to Wireless Performance Prediction July 2004 Welcome to Wireless Performance Prediction Charles R. Wright charles_wright@azimuthsystems.com C. Wright, Azimuth Systems

July 2004 Meeting Tone PLEASE Bring your Engineer Mentality and Technologist Attitude Please keep a Positive Attitude Please check your Ego and Politics at the door. We try hard to follow the process - not because we like process, but because enables us to conduct our meetings in a fair and efficient manner Try hard to understand another member’s viewpoint. Try especially hard to “hear” what they are not saying. Many disagreements arise from such unspoken assumptions. –Jon Rosdahl former HTSG Chair C. Wright, Azimuth Systems

Review IEEE/802 & 802.11 Policies and Rules July 2004 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

IEEE-SA Standards Board Bylaws on Patents in Standards July 2004 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

Inappropriate Topics for IEEE WG/TG/SG Meetings July 2004 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

July 2004 Name change for WPP? Our name is taken from the document title on the PAR: “Recommended Practice for the Evaluation of 802.11 Wireless Performance” It’s too late to change this without a lot of effort C. Wright, Azimuth Systems

Formation of Special Committees July 2004 Formation of Special Committees Environment Components Application Metrics? C. Wright, Azimuth Systems

Plan for now until Berlin July 2004 Plan for now until Berlin Template, next rev: Bob, Chris, Gerard Definitions list: Don, to be presented 29 July RF Environment types Device operating environment Device Configuration Metrics Application traffic patterns with metric Define test traffic to be used with metrics, where specific test traffic is required to test that metric C.
