Proposed Charter (1)
IEEE 802 Coexistence Technical Advisory Group (TAG) is responsible to recommend and maintain the IEEE 802 policy regarding coexistence among implementations of IEEE 802 and other standards.
To offer, when required, assessments to the SEC regarding the degree to which standards developers have conformed to coexistence criteria.
To develop coexistence documentation of interest to the technical community outside 802.
To assist, when requested by a Working Group running a ballot, with evaluation of proposals during the downselection process.
Jim Lansford, Mobilian

17. May 2003
Proposed Charter (2)
To assist, when requested by a Working Group running a ballot, with the resolution of comments related to coexistence.
To issue reports and recommendations to the SEC representing a balanced viewpoint regarding impending SEC actions in which coexistence may be a concern.
Approved per COEX-TAG, relevant Working Group, and LMSC rules. (see LMSC Rules, Procedures 3 and 4.)
To develop and maintain IEEE Standards (either Recommended Practices or Guides) to foster coexistence within the communications industry, provided that such work is done under an approved PAR.
The Coexistence TAG may recommend additional activities consistent with its Purpose Statement, subject to approval by the SEC.
