Interoperable 5.9GHz DSRC to Enable New Public
Safety Applications

What is DSRC?

• Dedicated Short Range Communications
• Message Exchanges between Moving Vehicles and
  beacons at the roadside
• Vehicles moving up to highway speeds
• High Quality of Service 99.995 delivery
• 10 to 150 feet range (today)
• Vehicle positioning is a by-product of the
  communication
• Today, most NA DSRC systems operate in the
  non-multilaterated LMS allocation 909.75MHz
  through 921.75MHz. A few backscatter systems
  operate at other frequencies in the 902-928 MHz
  band.
• There is a major US initiative to create
  standards and regulatory framework for DSRC at
  5.9GHz

3
Why DSRC?

• DSRC is an enabling technology for Intelligent
  Transportation Systems (ITS).
• ITS Technology can provide a solution to increase
  vehicle throughput without increasing roadway
  capacity as much as would otherwise be necessary.

4
Five Worldwide Transportation Trends Fuel Demand
for ITS and Mobile Communication Services
5
Worldwide Trends

• Increased Vehicle Miles of Travel (VMT) Led by
  Commercial Vehicles
• Limited Road Capacity Enhancements
• Increasing Congestion
• Lengthening Commutes
• Limited Government Funds

6
US Example Since 1990.

• VMT has Grown 38 Percent
• Traffic Delays in Urban Areas Have Increased 41
  Percent
• Average Urban Driver Spends 62 Hours Stuck in
  Traffic Each Year
• Average Time Spent Commuting has Increased 14
  Percent Nationwide

7
Inevitable Result.?

• North American motorist demand for, and
  willingness to pay for, in vehicle ITS and
  communications technology will continue to grow.
  
• What level and features are yet to be determined.

8
US DSRC Deployment Today

• Electronic Toll Collection Delivers in Excess of
  3.4 Billion Transactions Annually
• More Than 1.5 Million Trucks Electronically
  Comply at Weigh Stations Each Month
• E-ZPass Plus at Albany Airport Processes Payment
  Three Times Faster Than Manned Booths.
• McDonalds Pilot Test Showed 30 Percent Increase
  in the Dollar Value of Each Transaction

9
Example E-ZPass Today

• Twenty one agencies in nine states
• New York, New Jersey, Pennsylvania,
  Massachusetts, Maryland, Delaware, Maine, New
  Hampshire, West Virginia
• 10,000,000 E-ZPass transponders
• 3 Billion E-ZPass toll transactions annually
• 4 Billion in annually toll revenues
• Equipment contractually committed to 99.99
  accuracy

10
MOREEmerging Application Deployment

• HazMat Tracking in Wake of 9-11
• Platooning of vehicles
• Vehicle to Roadside
• Vehicle to Vehicle (V2V)
• Packet Hopping Internet Potential
• Dynamic Infrastructure Relying on V2V

11
And...mCommerce

• Fast Food Drive-Thru
• Parking
• Other Cashless Transaction Applications

12
What That Means for Transponders

• Additional Memory Separate Pages for All
  Applications, Especially Government vs. Private
• Faster Communication Speeds to Transmit
  Additional Data
• Enhanced Security, Especially Financial Services
• Onboard Integration

13
Chicken and Egg Scenario

• No Known Killer Application to Drive Deployment
  of New 5.9 GHz Technology
• No Tags No Roadside Infrastructure
• No Roadside Infrastructure No Tags
• No Applications or Potential Integration with
  Other Roadside Devices
• Standards and regulations are being developed
  anyway.

14
Where is DSRC Going?

• A new Frequency Band allocated by FCC for DSRC
• Public Safety applications
• Primary status
• Private Applications being considered
• 75 MHz (5.850 - 5.925 GHz)
• Multiple Channels
• Vehicle to Vehicle capability
• Extended Range and Data rates

15
Who When?

• ASTM is creating a standard for DSRC to operate
  and has defined the Physical and Media Access
  layers of the standard.
• The rest of the standard is still evolving and
  may be substantially complete within 6 months.
• OEM Automotive industry is on board and
  supporting the standard development

16
Regulatory Activity

• FCC 02-302
• Nov 7, 2002 NPRM and Order
• WT Docket No. 01-90
• Amendment re 5.9GHz Band DSRC
• ET Docket No. 98-95
• Amendment of Part 2 and 90 to Allocate the 5.850
  5.925 GHz Band to the Mobile Service for DSRC
  of Intelligent Transportation Services
