0~Stevenson, Carl R.~carl.stevenson@ieee.org~610-965-8799~610-704-2349~Agere Systems~00~00~00~00~TR~While this document does reasonable job of characterizing interference potential between 802.11 FH and 802.11b WLANs and 802.15.1 (Bluetooth) WPANs and proposing some methods of improving coexistence, I think it falls short of what is currently needed in the following respects: First, it will be obsolete in short order because it does not address the proposed 802.11g extension at all.  Second, neither does it address 802.15.3 WPANs.  Third, neither does it address 802.15.4 WPANs.  Finally, while it offers a definition of "coexistence," that definition is very "fuzzy" and essentially ignores the pressing need to quantify just what constitutes acceptable coexistence between systems and what does not.  What is needed is a "figure of merit" or "measure of goodness" that defines both how much a system is affected by other systems and how much it affects them, and that should apply to ALL 802 wireless standards that operate in a given band, not just a subset.~Provide a quantifiable definition of "coexistence" and methods of evaluation of the interactions between ALL 802 wireless standards that share a common frequency band, allowing those combinations of systems to be evaluated in a sensible, measurable manner and defining what is "good enough" to constitute acceptable coexistence and what is not.  Include analysis and simulation models of 802.11g, 802.15.3, 802.15.4 so that the COMPLETE coexistence picture of current and "in development" 802 standards in the 2.4 GHz band can be evaluated.  Propose (or, in the case of "in development" standards, insist that the developing workgroups propose and provide) coexistence mechanisms for ALL combinations of systems, with the onus on the "newcomer" to propose and provide coexistence mechanisms that can be shown to provide reasonable protection to incumbent systems, accoarding to the aforementioned definition of "what is good enough" to constitute acceptable coexistence.~~X~O
