No proxies Voting rules differ based on topic?

31. doc.:IEEE802.11-01/240r1 Submission May 2001 Bruce Kraemer, IntersilSlide 31 Procedures Used Today in MMAC & 3GPP MMAC Consensus decision making where possible Voting –requires 71% agreement One vote per company no weighting – simple majority Anyone can attend meetings – typically all conducted in Japanese For large companies, additional one vote per subsidiary is allowed if fee paid Do not know if Proxies are allowed? 3GPP Individual members are = companies Consensus sought- unanimous agreement If consensus not reached, One vote per company – no weighting Voting –approval requires 71% agreement Only members can attend meetings Proxies are allowed Voting rules differ based on topic?

32. doc.:IEEE802.11-01/240r1 Submission May 2001 Bruce Kraemer, IntersilSlide 32 5WING Voting Rights – First Draft Use entity voting – one vote per company (need to further define rights of divisions, subsidiaries, sectors, groups….?) This is acceptable under IEEE rules Equivalent to MMAC Minor deviation from ETSI rules Equivalent to 3GPP Are proxies to be allowed? How will operating expenses be collected? Membership fees ? Fees: per company, per meeting

New IEEE 802 standards will be added to the "Get IEEE 802" program, in PDF format, six months after publication. The "Get IEEE 802" pilot marks the first time the IEEE-SA has joined forces with industry to make a series of standards widely available. The program was established to assist potential users for whom the standard itself could be more costly than its actual implementation for network connectivity.

36. doc.:IEEE802.11-01/240r1 Submission May 2001 Bruce Kraemer, IntersilSlide 36 IEEE SA Policies Definition/Use of Consensus 8.3 - CONSENSUS IEEE shall ensure that its standards represent a consensus, to the extent possible, of all interests substantially concerned or potentially affected by the standards and that proper procedures have been carried out in their development. This implies that all interests shall have had an opportunity to submit input to, or comments on, standards proposals, that all dissenting views shall have been considered and addressed, and that an adequate appeal mechanism is available to parties objecting to a standard. Consensus embodies more than merely a majority but not necessarily unanimity.

37. doc.:IEEE802.11-01/240r1 Submission May 2001 Bruce Kraemer, IntersilSlide 37 IEEE SA –Standards Development NEW OPTIONS FOR DEVELOPING STANDARDS Traditional balloting on IEEE Standards has been by individuals. An employer funded many of these individuals. In a few cases the individual was funded by an organization and was identified as an organizational member of the balloting group. This tradition of individual balloting has been a hallmark of the IEEE standards process. Some standards developing efforts do not benefit from this traditional balloting process. Instead, there are instances where projects will benefit from a sense of organizational involvement and voice. Organizational involvement can offer: Accelerated standards development. Organizations can commit resources to conduct many meetings over a shorter time interval than customary, Continued involvement by the organization even if personnel changes occur, Organizational voting assures equal voting, a level field – not multiple votes from individuals having the same employer, Some projects are only available for IEEE sponsorship if decision making is "organizational", Organizations may offer quicker and wider distribution of information, may widely distribute draft information, and are more likely to purchase paper and electronic versions of approved standards. A study of these and other concerns over the last four years has identified need for IEEE to offer more options for developing standards. The options adopted by the IEEE-SA Standards Board to become available in 1999 are: Continuation of the traditional individual balloting without any change, and Entity voting (A combination of entity and individual voting is under consideration) An entity can be any type of "person" except an individual. Examples are a corporation; federal, state, provincial or local government agency; partnership and similar. The entity must be a member of IEEE-SA. The type of voting must be indicated on the PAR when submitted for Standards Board approval.
