The contributor also acknowledges and accepts that this contribution may be made public by IEEE 802.11. Patent Policy and Procedures: The contributor is familiar with the IEEE 802 Patent Policy and Procedures <http:// ieee802.org/guides/bylaws/sb-bylaws.pdf>, including the statement "IEEE standards may include the known use of patent(s), including patent applications, provided the IEEE receives assurance from the patent holder or applicant with respect to patents essential for compliance with both mandatory and optional portions of the standard." Early disclosure to the Working Group of patent information that might be relevant to the standard is essential to reduce the possibility for delays in the development process and increase the likelihood that the draft publication will be approved for publication. Please notify the Chair <stuart.kerry@philips.com> as early as possible, in written or electronic form, if patented technology (or technology under patent application) might be incorporated into a draft standard being developed within the IEEE 802.11 Working Group.

Month Year doc.: IEEE 802.11-yy/xxxxr0 May 2005 Abstract TGp objective is to enable IEEE 802.11 to support on-highway applications which includes many that are safety related. Lee Armstrong, Armstrong Consulting, Inc. John Doe, Some Company

May 2005 Summary Originated as an enhanced form of Dedicated Short Range Communications (DSRC) Expanded range of applications planned New spectrum allocated in North America Present 802.11p amendment based on ASTM E2213 standard Lee Armstrong, Armstrong Consulting, Inc.

History Dedicated Short Range Communications (DSRC) mature technology May 2005 History Dedicated Short Range Communications (DSRC) mature technology Most common use – electronic toll collection Simple command-response system Intelligent Transportation Systems (ITS) will use enhanced DSRC for vehicle to vehicle and vehicle to roadside communications New applications required changes to existing DSRC technology Primary impact on DSRC is operating range, security, quality of service under all conditions Lee Armstrong, Armstrong Consulting, Inc.

Planned Applications Safety related Public safety May 2005 Planned Applications Safety related Collision avoidance Alerts, warnings Signage Public safety Police, fire, ambulance Electronic fee collection Toll collection, retail sales General purpose Internet access Lee Armstrong, Armstrong Consulting, Inc.

Impact on Requirements May 2005 Impact on Requirements Extended range – 1 to 1000 meters Security Spoofing Denial of service Eavesdropping, unauthorized access Quality of service Very short latency (<75 ms total time entering zone to completion of transaction) Multiple overlapping communication zones with no interference Very high reliability under all conditions Full interoperability required All vehicles in North America All safety-related applications Lee Armstrong, Armstrong Consulting, Inc.

Spectrum Issues Safety applications require special spectrum May 2005 Spectrum Issues Safety applications require special spectrum Freedom from interference Control over use of band Spectrum allocated by FCC for DSRC use 5.850 to 5.925 GHz Licensed but no auctioning Compatible with Canada and Mexico Effort underway for ITU management of world-wide DSRC band Lee Armstrong, Armstrong Consulting, Inc.

From Existing to Current Standards May 2005 From Existing to Current Standards Previous generation of DSRC standards developed in ASTM ASTM International (formerly known as American Society of Testing and Materials) had DSRC subcommittee as part of ITS program Previous standards were in 915 MHz band Dealt with OSI layers 1 and 2 (comparable to IEEE 802) New 5.9 GHz standards started by same subcommittee Identified need to base technology on IEEE 802.11 Applications interoperability required full 7 layer set of standards plus security Upper layers assigned to IEEE P1609 and security to IEEE P1556 Lee Armstrong, Armstrong Consulting, Inc.

May 2005 Movement to IEEE 802.11 Making ASTM E2213 based on IEEE 802.11 proved difficult Desire to maintain current with future amendments to IEEE 802.11 Became SG, now TGp Existing ASTM E2213 standard used as basis for 802.11p draft. Name change from DSRC to Wireless Access in Vehicular Environment (WAVE) DSRC had no meaning in 802.11 world Some confusion with existing DSRC technology and applications Lee Armstrong, Armstrong Consulting, Inc.

WAVE Architecture May 2005 To Airlink Management Plane Data Plane WME UDP/TCP WSMP IPv6 MIB LLC Scope of P1609 standards MLME WAVE MAC PLME WAVE PHY To Airlink Lee Armstrong, Armstrong Consulting, Inc.

Full Range of Standards Under Development May 2005 Full Range of Standards Under Development Lower layers (PHY & MAC) – IEEE 802.11p First draft under review Plan to ballot summer 2005 Upper layers (LLC to Application layer) – IEEE P1609 Major revision completed April 2005, under comment resolution process prior to balloting P1609.1, P1609.3, P1609.4 being treated as a set, to be balloted as a set Security (all layers) – IEEE P1556 First draft to be distributed May 2005 Vehicle Safety Applications – SAE First draft under development, scheduled for completion late 2005 Lee Armstrong, Armstrong Consulting, Inc.
