Business


Things we take for granted

Outside the car•We can get weather and sport events from miles away

•We SMS, Skype, Twitter, and “My space” with our family and friends any time and any place

•We do business with partners from other countries which we may never meet.

In the car •We accept that flying airplane is safer than driving a car

•With our own senses and limited attention we keep track of traffic lights, speed limits and actions of other drivers

•Hand gestures and headlights remained most common way of wireless communication and safety advisories


Wireless communications – the missing link

• IntelliDriveSM is a suite of technologies and applications that use wireless communications to provide connectivity that can deliver transformational safety, mobility, and environmental improvements in surface transportation.

safety

• Cellular – Long range, always-on, voice-grade, but infrastructure is required minute based charges,

• Satellite – Broad coverage, one-way information distribution, but line-of sight limitations

• WiFi – Midrange, broadband, consumer accepted, but shared spectrum• Bluetooth – Short range, low power, supported in many communication devices• 5.9GHz DSRC - short to mid range, low latency, high-speed, dedicated spectrum


What is 5.9 GHz DSRC?

• 5.9 GHz DSRC is a secure wireless communication technology for point-to-point communication among vehicles and vehicle to transportation infrastructure for information sharing.

• Enables rapid and secure exchanges of data among vehicles and road infrastructure

• Designed to support cooperative safety and mobility applications


•Operate at freeway-speeds (up to 200mph)•Optimized for data exchanges•Short and intermittent connectivity•Mobile-mobile as well as mobile-roadside communication

•Provide scalable security•Leverage existing technology (i.e. 802.11)•Future-proof technology (i.e. IPv6)

5.9 GHz DSRC System Objectives


5.9 GHz DSRC is tailored for safety and mobility applications

Line-of-sight communication, allow flexibility in installations, larger communication “hot” zone

100-1000mSufficient range

Communication of collision warnings 10 times faster than driver reaction time

< 50 msShort connection time

Exclusive (Primary) usage for safety and mobility applications V2V and V2I

Interoperability and certification for devices will be required in the future.

75MHz FCC license required for devices

Licensed spectrum

What does it meanDetailsFeature

IEEE 802.11 IEEE 1609

128bit AES ECC-PKC

3-27 Mbps7 channels10 MHz

Use of open standards allow open procurement, interoperability between vendors and devices

Standard based interoperability

Anonymous and encrypted data communication. Certificate-based trust framework

Strong security

Two-way reliable exchange between vehicle and roadside, or among vehicles during short time.

High speed

Channel Switching for application multiplexing

•By default radio stay on predefined Control Channel•Switch to a Service Channel when participating in a WAVE Basic Service Set (WBSS)•Control and Service Channel intervals are 50 ms


Data communication over 5.9GHz WAVE/DSRC

•WAVE Short Message (WSM)•Point-to-point data exchanges without infrastructure support• Instant exchange of safety information among vehicles or between a specific RSU and vehicles nearby

• Internet Protocol (IPv6) Datagrams•Most common means for end-to-end communication with network routing

•Direct and secure data exchange with roadside and routing to back-office services

•Facilitates network build-out using COTS equipment•Provides robust mechanisms for network addressing and network management
