Roger,
I have one comment regarding the 802.k16r PAR.
Please explain the WG's rationale behind labeling the PAR with a particular application (SCB) as opposed to a generic label with it's functional capabilities (e.g., a BWA PHY/MAC with xxxxGbps peak capacity or throughput, etc.).
Another alternative is to take an approach similar to the 802.3 WG which labels some of their PHY projects simply with the peak data rate and physical media supported. This has the advantage, in my opinion, keeping the perception of the applications for the project wide open and, hence, may encourage wider participation.
Regards,
--Paul
