First of all, sounds excellent to me any initiative oriented to solve 
some of the limitations of the wifi specs which penalized it's usage on 
medium distances.

After a diagonal read, and I'm not the best in understanding some 
technical questions about RF communications dropped in the draft but to 
check my correct understanding of the overall and the impact that this 
could have at the real world:

-Is that draft something which is intended to be applicable to current 
deployed RF equipments 802.11b/g?
-Regardless of the response to the previous question, I assume that to 
make it successful, will require the support from the industry 
(manufacturers, drivers...), is that right? There is already any 
visibility on this?

Sorry if I missed something obvious already described in the draft.

Ramon.
