Re: stds-802-mobility: Fwd: [802SEC] UPDATE: URL Link for 802.11 PARs For Consideration by the SEC
All,
For the benefit of those who have not seen the subject 802.11p PAR yet, I have copied the PAR's Title and the Scope sections below:
---------- Title --------
Title: [Amendment to Standard [for] Information Technology - Telecommunications and information exchange between systems - Local and Metropolitan networks - specific requirements - Part II: Wireless LAN Medium Access Control (MAC) and Physical Layer (PHY) specifications: Wireless Access in Vehicular Environments]
---------- Scope --------
9. Scope of Proposed Project:
[Amendment of IEEE 802.11 to support communication between vehicles and the roadside and between vehicles while operating at speeds up to a minimum of 200 km/h for communication ranges up to 1000 meters. The amendment will support communications in the 5 GHz bands; specifically 5.850-5.925 GHz band within North America with the aim to enhance the mobility and safety of all forms of surface transportation, including rail and marine. Amendments to the PHY and MAC will be limited to those required to support communications under these high-speed vehicular operating environments within the 5 GHz bands.]
---------
Clearly, the Scope text above indicates that the wireless applications targeted by this provisional 802.11p project are vehicles-to-vehicle and vehicle-to-roadside communications. There is no overlap with 802.20, at least not in the targeted frequency bands of operation (802.20: below 3.5 GHz versus 802.11p: 5 GHz band). More over, vehicle to roadside and vehicle to vehicle communication (at max. range of 1000 meters) can hardly be confused with "cellular" architectures. So, what is the concern? -- that the title of the PAR spell out the WAVE acronym (Wireless Access in Vehicular Environments)? Or that there is a "hidden" overlap with 802.20. If we worry about overlap, we should take a closer look at the IEEE 802.16e project. There is definitely an overlap (with 802.20) here, as both standards target similar mobile applications and the frequency bands of operation overlap too (in the 2-3.5GHz range). So, should we ask the ".16e" folks to change the title of their upcoming st!
andard as well?
In summary, I sense that all such a motion would accomplish, if it passes, is to make the IEEE 802.20 WG look bad. Therefore, I do not support it.
Regards,
Dan

Jerry,
With regard to the concern I expressed in my February 17th note to the reflector (attached), please be advised that I am planning to present the following motion during our open plenary:
Motion: Request to 802.11 to change the title of their PAR (provisionally
802.11p) from "Wireless Access for the Vehicular Environment" to "Wireless Access for Intelligent Transportation System (ITS) Applications" to avoid the appearance of overlap with the work of 802.20.
All: Please review this motion and be prepared to vote on it on Monday or Tuesday morning. According to the 802 operating rules we must get all of our concerns to the working groups planning to submit PARs by Tuesday at 5:00pm, and we must do so in writing. Quick passage of this motion will allow us to concentrate on our primary work with little delay to handle this potential concern.
If anyone has any concerns with the proposed motion, please post your concerns to the reflector so that we can try to resolve potentially conflicting ideas with a minimum of meeting time.
Thank you.
Best regards,
Joanne

Jerry,
I reviewed the various PARs and don't see any that impinge on the work of 802.20. However, the title of project, "Wireless Access for the Vehicular Environment" (provisionally 802.11 Task Group p), could give the impression that there is an overlap. If others in 802.20 agree, we could propose that they use a different title for the project. One option could be, "Wireless Access for Intelligent Transportation System (ITS) Applications". Personally, I think they would also benefit in having a title that more clearly and accurately reflects their purpose.
Best regards,
Joanne

All,
The 802.11 Working Group has four PARs that will be reviewed and voted on by the 802 Executive Committee at the March Plenary. Please review and provide any comments. If there are specific items that warrant a discussion directly with an 802.11 representative, then we can request a representative and add to our agenda for March. Regards, Jerry Upton Chair, IEEE 802.20
