New Spectrum Allocation

• 75 MHz band has been allocated by FCC at 5.9 GHz
• No auction, no fees
• Band allows both safety and commercial
  applications to coexist
• Band is available now
• Site licenses for roadside units, license by rule
  for on-board units

4
Dont Confuse With Existing DSRC

• 915 MHz
• Range
• Data rate 0.5 mbps
• Designed for ETC, but can be used for other
  applications
• Single unlicensed channel
• Requires special (custom) chip set software
• Vehicle to roadside
• Command-response
• Expensive roadside units

• 5.9 GHz
• Range to 1000 meters
• Data rate 6 to 27 mbps
• Designed for general internet access, can be used
  for ETC
• 7 licensed channels
• Uses open off-the-shelf chip set software
• Vehicle to roadside vehicle to vehicle
• Command-response peer to peer
• Cheap roadside units

- The channels overlapping these zones may be
restricted in some locations in Canada. In these
cases use channels 1, 2, and 3 in their place.

Based on IEEE 802.11a

• High speed road impacts physical layer
• Very short latency (
• Random MAC addresses to preserve privacy
• IPv6 for network layer
• Multiple protocol options above network layer
• Support for in-car networks

Will become 902.11p, known as Wireless Access in
Vehicular Environments (WAVE)
