With all due respect, that is *not* what the industry is telling us.
Almost two years ago, the WFA standardized bandwidth attributes, but we
were unable to locate any vendor who had implemented those attributes, nor
any customer who had deployed them.

The reason why the attributes have not been deployed is *not* merely  
because of lack of hardware support, though that is certainly part of the 
issue.  802.11 vendors who already support 802.11 QoS schemes also have not 
implemented the specification, and do not plan to do
so in the future, because the current specification does not provide 
functionality equivalent to what is already supported on their APs.

Similarly, switch vendors who have support IEEE 802.1Q also have not 
implemented the specification -- and have indicated that they also do not 
plan to implement it in the future.

The "good news" is that there does appear to be significant interest in the 
general concept of bandwidth limitation, and were the document to be 
modified to address the issues developed in the review, it seems likely that 
vendor interest would increase substantially.
