IEEE 802.11p
802.11 is a set of
IEEE standards that govern wireless networking transmission methods. They are commonly used today in their
802.11a,
802.11b, and
802.11g versions to provide wireless connectivity in the home, office and some commercial establishments.
IEEE 802.11p is a
standard in the
IEEE 802.11 family. IEEE 802.11p also referred to as Wireless Access for the Vehicular Environment (WAVE) defines enhancements to
802.11 required to support
Intelligent Transportation Systems (ITS) applications. This includes data exchange between high-speed vehicles and between these vehicles and the roadside infrastructure in the licensed ITS band of 5.9 GHz (5.85-5.925 GHz).
802.11p will be used as the groundwork for
DSRC (Dedicated Short Range Communications), a US
Department of Transportation project â€" which will be emulated elsewhere - looking at vehicle- based communication networks, particularly for applications such as toll collection, vehicle safety services, and commerce transactions via cars. The ultimate vision is a nationwide network that enables communications between vehicles and roadside access points or other vehicles. The work builds on its predecessor,
ASTN a2213-O3.
Status
The 802.11p Task Group is still active. Per the
official IEEE 802.11 Work Plan predictions the formal 802.11p standard is scheduled to be published in April
2008.
