thank you Bob.
Just to clarify, from my perspective, the new clarifications make the CSD clearer, but highlight some issues.
The new project appears to be targeting ‘high data rate’ OCC. While OCC may be used at a bunch of data rates, it cites needs at 100 Mbps. To do this requires devices with cameras (and also therefore blink and modulation rates on emitters)
in the 10k to 100k frames per second – per the referenced examples now in the PAR. While such cameras do exist, often for machine vision in applications requiring slow motion analysis, they are often expensive sensors, aren’t your normal integrated video
sensor, not your normal cellphone or video camera, or even those discussed in connection with 802.3’s automotive projects.
While each element stands alone, my concern is that if the project takes the data rate seriously AND the ‘millions of existing devices’ seriously, and the ‘economic feasibility’ analysis, the conjunction of these may end up with a null
set of solutions. Personally, I’m considering abstaining.

Subject: [802.3_DIALOG] Fwd: [802SEC] Response to comments on 15.7a PAR/CSD
Importance: High
Colleagues,
Below is the official response to our (and other WGs) comments on the proposed P802.15.7a PAR and CSD.
There has been significant change in the CSD in response to our comments.
Mr. Zimmerman and I have been exchanging some emails privately on the below latest 802.15.7a documents. We both still have concerns about the claims for the viability of upgrading existing equipment. Even though the new 802.15.7a documents
reduce the claim from “billions" to “millions” for existing devices and many of the application markets we questioned in our comments have been deleted, the revised CSD claims still don’t hold up to critical analysis. Others that might want to provide opinion
to Mr. Law are invited to look at the new documents and comment on this Dialog reflector.

Hi All
Attached is the response to comments received from 802.1, 802.3 and 802.11.on the 15.7a PAR CSD. Also attached are updated copies of the PAR and CSD. Please let me know if there are any questions.
Best
