Patent Policy and Procedures: The contributor is familiar with the IEEE 802 Patent Policy and Procedures < 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 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 Working Group.

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

4. 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.

5. 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.

6. 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.

7. 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 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.

8. 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
Applications interoperability required full 7 layer set of standards plus security
Upper layers assigned to IEEE P1609 and security to IEEE P1556

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

Full Range of Standards Under Development
Lower layers (PHY & MAC) – IEEE p
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, P 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
