July 2004 doc. : IEEE 802. 11 -04/xxxr 0 5. 9 WAVE / DSRC CONCEPT 5. 9 GHz WAVE / DSRC (Dedicated Short Range Communications) is a short to medium range communications service that supports both Public Safety and Private operations in roadside-to-vehicle and vehicle-to-vehicle communication environments. 5. 9 WAVE / DSRC is meant to be a complement to cellular communications by providing very high data transfer rates in circumstances where minimizing latency in the communication link and isolating relatively small communication zones are important.

July 2004 doc. : IEEE 802. 11 -04/xxxr 0 5. 9 WAVE / DSRC USAGE REQUIREMENTS (continued) • Receipt of Vehicle Safety Messages must not be interrupted for extended periods of time. Extended periods of time probably means somewhere between 100 and 500 ms or more • Some transactions will take more than 100 ms to complete and we want to maximize the efficiency of channel usage • The Car companies want the ability to implement Vehicle Safety Messages and the Cooperative Collision Avoidance Application with a one channel radio Submission 7 Broady Cash, Justin Mc.

July 2004 doc. : IEEE 802. 11 -04/xxxr 0 PUBLIC SAFETY Messages Have Priority • Management Frames have a higher priority than any priority of data frame. Beacon Frames have the highest priority but only one level. Levels of Priority must be added to Action Frames. • High Priority Public Safety Broadcast Messages are sent in Wave Service Information elements in Beacon Frames from RSUs or Action Management Frames from OBUs. • Quality of Service Data Frames have priority levels that allow further delineation of priority among applications • Private Application Messages are sent in Action Frames on the Control Channel and Quality of Service Data Frames in Service Channels Submission 8 Broady Cash, Justin Mc.
