Re: WLAN/ New Structure of the Coexistence Group
Coexistence across wireless working groups is vital, therefore I favor options 2 or 3 over option 1. New proposals for the unlicensed bands must be evaluated
based on still yet to be established coexistence guidelines. No new standards should be developed for the unlicensed bands without *first* establishing these
guidelines. Either forms 2 or 3 seem capable of establishing coexistence guidelines.
Which structure is best depends on operating principles. I believe it is important that application of the coexistence guidelines be based on principle and 802
must avoid creating new wireless standards (now or in the future) that operate in the same radio space and yet do not coexist with any of its viable existing
standards in that radio space. Membership in various wireless working groups may increase or decrease as standards appear and mature. Therefore, there appears
to be a problem with managing coexistence through a joint task group which votes to approve new wireless standards, since the votes might just reflect relative
numbers of active voters in working groups, rather than rational coexistence principles.
This leads me to ask about a (fourth?) option where a joint task group (as Steve and Al have proposed) *develops* guidelines and then ExCom them self (or an 802
Wireless Coexistence Working Group) *applies* the guidelines in some predetermined fashion.
