Dedicated Short Range Communication (DSRC) is an IEEE 802.11-based platform for
|
|
|
|
|
vehicle-to-vehicle and vehicle-to-roadside infrastructure communications.
|
|
|
|
|
A variant of 802.11, 802.11p, makes use of a designated spectrum,
|
|
|
|
|
with some minor adaptations to the basic 802.11 WLAN standards, to handle the
|
|
|
|
|
particular challenges of short-range communications in the vehicular environment.
|
|
|
|
|
In addition to the low level wireless communications platform defined by 802.11p,
|
|
|
|
|
additional standards define higher-level protocols for short messaging and
|
|
|
|
|
message content, including the IEEE 1609.x family, as well as SAE J2735 and J2945.1.

|
|
|
802.11p specifies an additional mode of operation called OCB (Outside the Context of
|
|
|
|
|
a BSS) mode that allows stations to communicate in a broadcast mode without having
|
|
|
|
|
an established connection to an access point (BSS) or another station (peer-to-peer).
|
|
|
|
|
This mode of operation could be used on any spectrum available to 802.11 transmissions,
|
|
|
|
|
although some of the spectrum area in the 5.9 GHz range has been allocated for 802.11p use in
|
|
|
|
|
DSRC communications.
