[Phil Barber] The current IEEE 802.16-2004 document supports fixed (as defined in the standard, which may include nomadic use) service in LE bands. 802.16e PAR specifies application in licensed bands only. Since any LE TG would be an amendment document to IEEE 802.16-2004, as modified and amended by 802.16e, 16f, and 16g, the contemplated LE TG would be similarly constrained until such time as a new PAR defining LE 802.16 mobility service is considered and approved. Until that time, it would be out-of-scope for any LE TG to address functionality not supported in the current or pending standard projects. Leave the word 'fixed' in; take it out. It makes no difference. Presence of the term does not affect the inherited restriction. Unless we are considering starting a new project for 802.16 LE mobility in the near future, we are probably best served leaving the 'fixed' in the proposed scope.
