Meeting Etiquette • IEEE 802 is a world-wide professional technical organization • Meetings are to be conducted in an orderly and professionalmanner in accordance with the policies and procedures governed by the organization. • Individuals are to address the “Technical” content of the subject under consideration and refrain from making “personal” comments to or about the presenter. Rich Kennedy, Research In Motion
Task Group Chair’s Functions • [From the 802.11 Working Group Operations Manual] • The TG Chair may decide non-technical issues or may put them to a vote of the TG. The TG participants and the Chair decide technical issues by vote. The TG Chair decides what is non-technical and what is technical. • The TG Chair is responsible for presiding over TG sessions. • The TG Chair shall operate the TG in an unbiased fashion. To maintain impartiality, the TG Chair shall refrain from taking sides in debate on technical motions. • It is the responsibility of the TG Chair to lead the TG in producing a quality draft standard in a timely fashion as specified by the specific PAR Rich Kennedy, Research In Motion
Introduction • WELCOME to the sixth face-to-face meeting of IEEE 802.11 TGaf! • On Friday, November 20, 2009 the IEEE 802.11 TGaf was approved by the EC (10/1/4) with this motion: • Believing that the PAR and Five Criteria contained in the document referenced below meet IEEE-SA guidelines, • Move to forward the 802.11 TVWS PAR information from 11-09/934r8 to NesCom. • On December 8th NesCom approved the formation of the Task Group for P802.11af • We are heading down the homestretch to the first WG letter ballot, needing only to clean up the draft and incorporate changes from FCC 10-174 Rich Kennedy, Research In Motion
PAR Scope and Purpose • Approved PAR Scope: An amendment that defines modifications to both the 802.11 physical layers (PHY) and the 802.11 Medium Access Control Layer (MAC), to meet the legal requirements for channel access and coexistence in the TV White Space • Approved PAR Purpose: The purpose of this amendment is to allow 802.11 wireless networks to be used in the TV white space Rich Kennedy, Research In Motion
Purpose, Principles and Vision/Outcome“If you don't know where you are going, you might wind up someplace else.”* • 11-06-0056-00-0000-cbp-and-david-allens-methods • http://en.wikipedia.org/wiki/Getting_Things_Done • Purpose: the Task Group should create an amendment whose implementation in solutions is likely to receive FCC approval for operation in the TV White Spaces under the 47 CFR Part 15 subpart H rules. • Principles: • If the FCC changes the rules, the Task Group should change the amendment accordingly • The amendment should not duplicate functionality that is being standardized in other Task Groups that are likely to complete before 802.11af. • There is no need for backwards compatibility with 2.45 GHz ISM operation. • The starting point is changes to Clauses 17 and 19 and Annexes D and E • Vision/Outcome: Use the OFDM PHYs with 5-, 10- and 20-MHz channel widths to specify the basis for a system that the regulators can approve for operation in the TVWS bands. * Yogi Berra Rich Kennedy, Research In Motion
TV Bands Regulatory Requirements • These [FCC] rules are primarily intended to ensure the efficient sharing of the TV Bands while protecting incumbent users • The FCC has enabled this band for TVBDs if and only if the licensed users’ interests are protected • We must not interfere • Mitigation of any interference issue should not increase the enforcement requirements for the Commission • There are no formal changes in regulatory status since San Diego • Expected announcement on September 23rd at FCC Open Meeting Rich Kennedy, Research In Motion
