I was
thinking along the same lines.
Not to
throw a monkey wrench into the works, but I am curious ... if the 802.11p
transport of data is relied on for safety things such as collision avoidance,
etc., what happens if the link fails to operate for any of a number of
reasons? (And does this require some additional explanation in item
18?)
Again,
I am not trying to obstruct progress, just not clear on how safety
aspects/implications are isolated/divorced from network/data transmission
reliability (or failure thereof).
Regards,
Carl
Comments:
1. I congratulate the study group on producing
thoughtful and detailed responses to the Five Criteria.
2. PAR item 19 -- The additional information raises
a concern as to why the provided text was not included in PAR item 18.
If I understand the nature of the project correctly, the 802.11 standard
itself will not address the safety issues of the cited possible applications
(e.g., collision avoidance), but will simply be providing connectivity and the
safety issues will be addressed by other standards or specifications that use
the provided vehicular wireless access. If this is correct, I would
recommend addition of a sentence to this effect to the note in 19. If it
is not correct, the paragraph in 19 should be moved to the explanation field
of 18 as an appropriate red flag of the intended use of the
standard.
