Leaders in the Industry don’t want to start with a multi PHY endorsement –Multiple interoperability programs at the Wimedia (won’t happen) –Multiple solutions for WUSB promoters group (won’t happen) –Complexity in the channel The common signaling mode isn’t a compromise proposal or interoperability proposal, it’s a co-existence proposal for dual PHY Co-existence of other PHYs outside 15.3a may decide to place a mechanism to detect 3a preamble and include mechanism to coexist. A true compromise proposal must be something that each side can find to be minimally acceptable. No one has proposed something that meets this requirement.

A compromise or agreement is the package (combination of options across all issues) that both negotiators jointly agree upon after exchanging a sequence of offers. The art of dividing a cake in such a way that everybody believes he got the biggest piece. Placing an adversary in a position of vulnerability. a middle way between two extremes settlement of a difference of opinion in which both sides agree to give up a part of its demands.

We do not have a PAR for creating a specification for coexistence of multiple phy’s. (due diligence) –Fairness based on application and user priorities. –Mesh, mobility. –Dynamic range –Upper level logic and policy. –Use cases. –Etc. Compromise should be a process between the authors, not a forced action.
