Bob,
Your first assumption is correct i.e. "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". This was the sentiment of the group. Indeed IEEE groups P1609
(Layers 3 and above for Wireless Access in Vehicular Environments (WAVE)
communications) & P1556 (security for WAVE systems) are working closely at
the upper layers with the National Public Safety Telecommunications
Council on public safety
requirements.
Therefore, to address your concerns with your good
suggestion the corrections to the paragraph 19 would read:
19.
ADDITIONAL NOTES: The primary use of the
amendment will be in support of surface transportation safety
applications. Some examples of such applications are: intersection
collision warning, stopped vehicle hazard warning, emergency vehicle approach
warning, work zone warning, and road hazard warning. The standard will not
address the safety issues of the cited example applications above, but will be providing
connectivity where the safety
issues will be addressed by other standards or specifications that use the
provided vehicular wireless access.
If this is suitably accepted, then it would be added to
the submitted PAR for NesCom.
Respectfully,
Stuart

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.
